Putting the cool in cooling A number of years ago, I had the opportunity to chat with Mike Rowe, the perpetual apprentice and host of the show Dirty Jobs. One item that stuck with me was his concern for society once there are not enough professional, licensed tradespeople available to install what needs to be installed and ﬁx what needs to be ﬁxed.

Check out our digital archive! If you’d like to have a look at our chat with Mike Rowe, and any of our other celebrity encounters, be sure to check out our back issues, in digital format, at mechanicalbusiness.com. Just click on Digital Issues, under the “More” tab on the site. And if you are in need of a new hat, shirt or beard pomade that supports the hard work of trades pros, check out trollcoclothing.com.

From the time that I started writing in this sector, close to two decades ago, we’ve been talking about pending personnel shortages and the difficulty attracting young people to the trades. Unfortunately, not much has changed from the time Mike and I chatted, except that we keep getting closer and closer to a tipping point that most of us would not like to reach. Let’s face it, when a consumer can’t find – or afford – a trained professional, they are far more likely to turn to a jack-of-all-trades or cousin’s-roommate’s-neighbour – you know, the people whose work pros fix on a regular basis. The potential for cross connections, improper joints and other risks is a scary thought.

A number of the journeymen on the trip were sporting on-trend attire with the trades-positive message: “Dirty Hands, Clean Money.”

EDITOR’S

To ensure we have a steady ﬂow of new people into the ﬁeld, Mike suggested that we need consumers to become fans of the trades, so that they would not talk young people out of an apprenticeship. A recent work trip with a group of skilled trades professionals has me thinking that we might be able to tap into that idea by doing a bit of a brand-building exercise.

We acknowledge the support of the Government of Canada.

Prompt payment Bill passed into law Canada’s ﬁrst federal prompt payment law received royal assent on June 21. Bill C-97, the Budget Implementation Act, 2019, contained the Prompt Payment for Construction Work Act, which lays the foundation for prompt payments throughout the construction chain on construction projects procured by the federal government. Legislation has been years in the making and was made possible through the hard work of a number of industry groups, as well as politicians and other civil servants. “It was a long journey but this will be welcomed by our commercial HVAC/R contractor members that work on federal construction projects,” HRAI said in a statement. hrai.ca

Lifting of tariffs a win for business The lifting of steel and aluminum import tariffs throughout North America in late May was broadly welcomed by Canadian businesses. Canada had imposed a tariff of 25 per cent on steel and 10 per cent on aluminum after U.S. President Donald Trump imposed identical import taxes last summer. The tax had increased prices on many plumbing and HVAC/R products, but it is now hoped a period of price stability will follow the agreement. “While there’ll be some challenges... in the long term it will be a better outcome for Canada and for North America,” said Canadian Manufacturers and Exporters Association president and CEO Dennis Darby. canada.ca

Natural Resources Canada has published amendments to its Energy Efficiency Regulations in the Canada Gazette Part II. The changes contained in Amendments 15 and 16 update existing energy standards for a number of product categories, including a wide range of mechanical system components. Products affected include several types of furnaces, boilers, HRVs and water heaters. Both amendments will come into force on December 12, 2019, with the exception of changes to efficiency requirements for through-the-wall furnaces, which have already come into effect. A key change is the introduction or increase of Minimum Energy Performance Standard (MEPS) levels for many of the affected product categories. For the most part, the revisions will align with regulations that exist in the U.S. and will be phased in between now and 2025. “Natural Resources Canada has published these new amendments as a part of Canada’s approaches to meet its greenhouse gas reduction targets and the amendments are intended to eliminate the least efficient energy-using products from the market,” explained Chang Lee, technical advisor with industry body HRAI. “While the amendments typically align HVAC/R product testing and efficiency requirements to those in the U.S. to reduce regulatory burdens, Canada-specific energy efficiency levels apply to some HVAC/R products due to unique Canadian circumstances.” gazette.gc.ca

Job vacancy rate grows The shortage of skilled trades workers continues to bite across the country, with the job vacancy rate in construction hitting 4.9 per cent in the first quarter of 2019 — the highest of any sector. According to the Canadian Federation of Independent Business (CFIB), total private sector job vacancies reached a new high of 3.3 per cent in the first three months of the year, although the rate of growth appears to be slowing. CFIB’s latest count represents roughly 435,000 private sector unfilled openings, almost 13,000 more than in the final quarter of 2018.

Few Ontarians have serviced their AC A survey of more than 1,000 Ontario homeowners has found that only 60 per cent of Ontario homeowners test their air conditioner on an annual basis, and only 30 per cent have had their air conditioner serviced within the past year. In contrast, it is clear that air conditioning is something the vast majority of Ontarians value as almost three-quarters (74 per cent) of respondents to the survey stated they would not buy or rent a home that does not have air conditioning.

Reader Proﬁle Wally Boonstra: Feeling good about giving back

Whether it’s offering young people the opportunity for a good career, or passing along education by sharing knowledge from journeyman to apprentice, the skilled trades have a long history of giving back, but Wally Boonstra doesn’t just stop there. Boonstra, the owner of Excel Heating & Air Conditioning Systems, an HVAC ﬁrm with 15 employees just west of Toronto, joined the industry when his uncle, Clarence Boonstra, gave him his ﬁrst apprenticeship. Learning from industry titans like his uncle, as well as Paul Messenger, past-owner of A1 Air Conditioning, imparted a wealth of business knowledge, and a strong sense of community. As we chatted, Wally explained that he truly enjoys the feeling that he gets when he gets a chance to give back for the betterment of his community, volunteering his time, experience, and even his team of trades pros to worthy causes. He’s currently helping with a Habitat for Humanity build, donating the HVAC systems for a triplex near Hamilton, Ont., and hopes to be able to do more such builds in the future.

Q A

What’s the most interesting project that you’ve been involved in over the years? We recently completed the installation of four large boilers, a total of 1.6 million BTUs, in one of the largest homes in Southern Ontario. What made it interesting was the complexity of integrating the whole system. There’s snowmelt, 19 air handlers, pool heat, in-ﬂoor heat and domestic hot water. What's the biggest challenge for a mechanical business nowadays?

HIGH-PERFORMANCE HVAC

SUCCESS WITH

VRF I think it was about 12 to 15 years ago that I first read about VRF systems – Variable Refrigerant Flow systems – making their way to North America. It was around the time that ductless minisplits were finding their way into more and more applications, and the leading manufacturers were promising a compelling opportunity to apply the related VRF technology to a much wider array of commercial and institutional applications. I suspect many of you will already know the advantages of applying VRF technology, but a quick review of a few of those is warranted before we consider some installation specifics. VRF technology might be described as nimble. Seemingly large, complex applications can be made modular. Multiples of small, relatively lightweight outdoor units that are easily transported and located are coupled together to serve equally small and compact indoor units to allow individual climate control of diverse spaces. There is inherent flexibility available in both how the system can be applied in stages throughout a

long build cycle and in its ultimate operation. The variable speed compressors can adjust to part loads in individual spaces and, with multiple compressors available, the total system can be heating and cooling different spaces at the same time, and even recover energy from one space to be used in another part of the building. That kind of flexibility and the variable speed compressors result in very high heat pump energy efficiency. Imagine how this nimble, efficient technology fits so well with the drive toward zero energy buildings where the intermittent heat gain load of large windows can be quickly and efficiently accommodated without compromising the comfort of occupants. It should be no surprise that the growth of VRF applications in North America has outpaced the growth of traditional unitary equipment in commercial and institutional markets – a growth rate averaging 15 per cent per year over the past five years or so.

A SERIES OF REPEATABLE PROJECTS

SUCCESS BREEDING CREATIVITY

The very first VRF job tackled by Mike Martino of Can Air Mechanical left him with a wealth of advice that any contractor can deploy.

The success of VRF in meeting the efficiency and control expectations of building owners has spurred the development of new versions of VRF that feature even smaller, more compact outdoor units at more competitive prices in both single and three-phase configurations to allow for a wider array of applications.

Looking at a 322-ton VRF application for a new medicinal cannabis production facility in Hamilton, Ont., he admits that it seemed daunting. After all, there were 43 outdoor units and 49 indoor units, but Mike explained to me that he was able to see the project as just multiples of small, repeatable modules – not unlike

the mini-split projects that many contractors are familiar with. Each indoor space and its corresponding ductless unit linked back to the rooftop equipment with individual refrigerant and control lines. With a bit of assistance from suppliers, and following

their instructions about wiring and refrigerant lines, he was able to get the system up and running with very few hiccups along the way. Says Mike, who is now working on the second phase of the facility, “Don’t over think it. VRF is not difficult, it’s just different!”

WIRING IT ALL UP One of the defining virtues of VRF systems is the individual space control capabilities of these applications. Of course, the spectre of complicated wiring and programming could be a deterrent to some contractors so I was anxious to get Mike Martino’s thoughts on that from his first project. He explained that he took steps to ensure success, running the control lines with the same care and attention to detail as the refrigerant lines, with ample documentation and testing. A helpful hint from one manufacturer is to do a continuity (ohm) check on those long, small gauge control wires before even starting the cabling, just to be sure you aren’t wasting efforts on compromised cables. When it came to the final connection and startup of those first units, Mike admits there were crossed fingers but, in the end, he wasn’t really surprised that everything worked as planned. In his research prior to the job, he had found all of the leading manufacturers have embraced a plug-and-play concept with a modular approach to heating and cooling large buildings. Perhaps the most important attribute of VRF to mechanical contractors is the integration of controls with the mechanical components.

I have recently been intrigued by engineers who are looking into marrying traditional unitary equipment, which is often better for large open spaces, with VRF systems that are perhaps better suited for individual, special purpose areas of the same building. Much as I have reported on hybrid systems in residential applications, forward thinking engineers and mechanical contractors will be using combinations of VRF heat pumps and more traditional unitary equipment to enhance the health, comfort, durability and energy efficiency in both new and retrofit applications.

FACING TECHNICAL CHALLENGES As Mike Martino explained to me, and most experienced contractors will agree, the final installation of every large mechanical project will vary from the original engineered design. In a VRF job, it’s necessary to watch changes that could affect refrigerant management. It is vital to measure, document and adjust to the length

and size of the refrigerant lines, explained Mike, down to the nearest foot. Fortunately, the leading VRF equipment manufacturers will provide technical guidance with respect to amount of refrigerant and the required commissioning pressures, if they are given thorough documentation of the installed lines.

With the exception of the mainframe, I have owned them all at one time or another and employed them in my business. What has this done for and to society? It has disrupted almost everything.

EVOLVE OR BE LEFT BEHIND A mobile mob bile base base We now have the entire knowledge of the world at our fingertips. In fact, 75 per cent of homes in the United States now have at least one smartphone and last year, for the first time, mobile access to the internet was more popular than desktop browsing.

From home systems to social media, we are connected to everyone and everything we want to be, and this technological evolution is disrupting industries of all kinds. I can now book a car that is not a taxi. I can find a place to stay that is not a hotel. Industries are being completely turned upside down every day. This hyper-connectivity has completely changed the way that we act as consumers. Technology has given us an incredibly granular anular level of control.

Change is always coming, but those who embrace it are the ones who will succeed. Our future is in our own hands.

Keeping ahead of the curve, with Roger Grochmal Kodak is a famous example of a business that didn’t move quickly into the digital era and paid the price. In Canada, Sears was one of the earliest “shop from home” businesses with their catalogues, yet they moved away from that model, rather than envisioning how the company could change to keep up with the times. On the other hand, change often provides an amazing opportunity for organizations to reposition themselves in a stronger way. Staples Canada has evolved from warehouse-style office supply stores to providing dynamic co-working spaces. Clearly, Staples Canada understands the growing demand for collaboration, connection, and community-whereyou-work, and it has cleverly avoided the danger of becoming obsolete as society shifts from pen-and-paper work to digital solutions.

STAYING STRONG, IN BUSINESS How do we evolve our organizations so that we don’t fall on the pile of obsolescence? Firstly, ensure all processes and systems are up to date. Can your customers book their service appointments, track your service truck, pay, and leave an online review, all from their smartphone? We just completely redid the AtlasCare website to meet current mobile-friendly standards because we wanted to ensure the best possible web experience for our customers. Don’t forget to ensure your online privacy and data protection systems are up to code, too. Secondly, ensure that your staff is equipped with the necessary technology and training to provide the service your customers are expecting. This can include being well practiced in

using the tools for doing business, such as a tablet that is “hotspot” connected to their smartphone, as well as the newest innovations in the industry like smart thermostats, zoning system design and greywater recycling systems. Thirdly, and most importantly, communicate with your customers. Where are they searching for information about your service? How are they talking about you? What are they asking? Consider educating your customers and prospects through a blog, social media, or other method that best suits your audience. You are their principal source of information about the world of HVAC and plumbing, and this is your opportunity to become their go-to expert.

PLANES, AIRPORTS AND DOMESTIC HOT WATER A UNIQUE PROJECT The Calgary airport is a city within a city, with some interesting code applications that allow it to adapt to the needs of such a huge place. For example, gas and water pressures are many times above the maximum allowed pressures in most normal buildings, so there are some unique piping designs needed. Next time you travel through an airport, remember it’s got some banged up mechanical helping take care of its people and planes.

HOT WATER AT YYC Fun facts about the domestic hot water system at the Calgary airport: • Two 900-gallon hot water tanks feed all the domestic hot water for public spaces. • The system serves a 2 million square foot building. • The airport sees 18.3 million passengers per year. • There are approximately 150 washroom groups in the facility. • Up to a year’s worth of trended use can be tracked on a sophisticated BMS.

M e c h a n i c a l

t was a cold, humid, winter day as the plane sat idling on the frozen tarmac of the municipal airport in London, Ont. The year was 1979. My Steelers would play the Los Angeles Rams in the Super Bowl in just a few days, but I sat uncomfortably in my passenger seat nervously watching the maintenance men de-ice the wings of the plane. When you are just 19 and have never flown before, all sorts of catastrophes run through your mind. My anxiety and nerves must have shown, or maybe my new tie was too tight, but for whatever reason, a pretty stewardess (that’s what we called flight attendants back then) sat beside me and reassured me of the short, safe flight to Toronto. I was really worried that I would get plane sick and throw up all over my new suit – my brother did that a year earlier on his first flight. I was so worried that I didn’t eat the day before so that my stomach would be empty. After a little while, the propellers started rumbling, the plane vibrated a bit, and we started to roll down the tarmac. On take-off, I was glued to the window, watching as the buildings began to shrink and people turned into insect size bodies. I still remember grasping on to my armrests every time the plane shook from a rough spot. As the plane went higher, feelings of nausea and light headedness set in. All I could think was: do not throw up all over my brand new dark blue suit, and definitely do not throw up on the pretty stewardess who kept coming by. I somehow made it to the tiny bathroom. I wanted to throw up, but I couldn’t figure out how to flush the toilet. What kind of idiot plumbing apprentice was I? Too embarrassed to leave vomit in the toilet, I held it in and slowly slumbered back to my seat. After about just 15 minutes, the concerned stewardess looked at me and asked if I was alright. I tried to act cool, and attempted a smile, but my white sweaty face gave me away. She was very caring, eventually convincing me to chew some gum that she had brought out. After chewing the gum, my ears popped and I began to feel better. I was so relieved that I didn’t throw up on her, that I was able to relax and ponder my future.

MARVELLING AT MODERN SYSTEMS Iâ&#x20AC;&#x2122;m a seasoned veteran of ďŹ&#x201A;ying now and, equipped with my pack of gum, air pressure doesnâ&#x20AC;&#x2122;t bother me. A recent landing in the new international wing of the Calgary airport had me feeling pretty good, except for having a full bladder. I hate going to the bathroom on airplanes. The ďŹ rst thing I did after landing was run to one of the new washrooms. I love new plumbing. As I washed my hands in the lavs, I noticed how the perfectly tempered hot water immediately ďŹ&#x201A;owed from the new faucet. I know a little about the mechanical of this airport thanks to Danny Coles, a former student of mine who is now in charge of the mechanical at the airport. Danny and I have probably done around 10 tunnel tours

for my 4th-year apprentice students. On any given tour, you can witness 40 to 50 years of mechanical evolution. The mechanicals run through a ďŹ ve-kilometre maze under the airport, and Danny is the perfect guide for this tour as he is like a Wikipedia of the airportâ&#x20AC;&#x2122;s mechanical systems and history. One of the things Iâ&#x20AC;&#x2122;ve noticed about the older sections of the airport is that they seemed to like to hide the piping in small chases, thereby making it more difďŹ cult to access for the tradesmen. Even the old tunnels were smaller. The new tunnels are more like a modern freeway in size and structure. The new wing of the airport displays hundreds of cross connection devices â&#x20AC;&#x201C; way more than the old section â&#x20AC;&#x201C; and also boasts a fairly dynamic geothermal system with several hundred bored wells.

One of my major pet peeves in many older high-rise buildings is the lack of balance or quantity of hot water in these large buildings, which is why I can appreciate the water delivery at the airport. When a shower takes too long to warm up there is either a problem with the recirculation pump or the system was inadequately designed. In newer buildings, we try to include more balancing valves than just the one interconnecting the riser and recirc line, in order to provide an even distribution of hot water throughout the building. I thought a 30-storey building was intense enough to ﬁgure out the hot water supply demands, but you ain’t seen nothing until you’ve seen the domestic hot water demands of an airport.

HANDLING THE COLD A couple of years ago, Danny Cole ran into a situation where he and I had to troubleshoot a domestic hot water issue at the Calgary airport while keeping the system active and providing hot water to the public facilities. A cold snap had temperatures down below -20°C for an extended period and the radiant system was stealing the majority of the heating load to keep the perimeter of the building warm. Since the domestic hot water tank was at the end of the heating loop, it was struggling to keep the supply water temperature at a safe level. While troubleshooting, we found that one of the two boilers had failed, leaving only one to supply radiant heating and domestic hot water. By rerouting some heating lines for a

more direct ﬂow to the hot water tank bundle, and by making a few adjustments to the recirculation pumps, we were able to keep the system fully operational without any domestic hot water interruptions.

Quality work builds a quality rep Before I joined this esteemed publication, the only previous times I had come into contact with members of the mechanical trades was when something in my house had gone awry. Having never been someone you could describe as being “gifted with his hands,” even small problems would have me desperately scanning Google for a saviour. The biggest fear of the mechanically naïve is being taken advantage of by an unscrupulous technician. We’ve all heard horror stories of outrageous charges and shoddy workmanship, and I’m sure many of you have been called in by a desperate Never stop learning homeowner to ﬁx something that had already “been repaired.” As systems and regulations But having had my feet under the table here for a little under a year, the thing that has struck me most, whether talking to techs or mixing with company owners at industry events, is how much everyone cares about what they do; how much they love helping customers and solving their problems.

GUEST COMMENTARY

Helpful resources and modern technology

hen I first started in the industry, I needed to educate myself about hydronics, boiler design and troubleshooting. At the time, the resources were very limited. The most accessible materials were either short, quick reads about pumping and piping or 350-page textbooks. While these were great educational pieces, they were not very convenient. If I was on a site troubleshooting, I couldn’t just pop open to page 175 and read about short cycling a boiler. In just under a decade, the resources available to us have become so much more advanced. We can now program our boilers to send warning and troubleshooting notifications to us via text message or email. And we now have apps on our phones that allow us to monitor and receive real-time updates for systems we have worked on. Our troubleshooting capability and time spent troubleshooting has become so much more efficient. No longer are we expected to scramble on a site to find equipment manuals (if they haven’t been thrown away), flip to a troubleshooting guide and try to find our error code before going through the steps to resolve the problem. We can study issues before we get to the site, because we know exactly what the error message is and the time that it happened. Technical advances have given us interactive troubleshooters, control simulators and short how-to videos on equipment websites, all of which can help to get us in and out of job sites more quickly. Imagine receiving a text message notification letting you know that one of the boilers you installed three years ago – one you’ve completely forgotten about – has a high-limit error code. You need to get to the site and fix the problem because there is no heat in the house. You quickly open your phone, type the name of the manufacturer into your browser, and click on the interactive troubleshooter to find a step-by-step guide as well as a simulator so you can actually practice the repair before you get to the site. Not only will you fix the issue, but you will look like the ultimate professional at the same time, and that’s pretty slick.

Making use of drive time I use a number of educational platforms, and ﬁnd podcasts and YouTube to be great opportunities to learn. I have listened to hours and hours of podcast episodes about buffer tanks, hybrid systems, circulation in hydronics systems, air in hydronics systems, and more – often while in my car. The best part is all this information comes from the very different viewpoints of manufacturers, designers and technicians. You get everyone’s perspective on their way to put systems together and to resolve issues.

Catching up during

SUMMER BREAK

Bob “Hot Rod” Rohr has been a plumbing, radiant heat and solar contractor and installer for 30 years. A long-time columnist and trainer, he is manager of training and education with Calefﬁ North America. You can reach Hot Rod at bob.rohr@calefﬁ.com.

o me, the summer months seem to be a great time to catch up, relax, and finish those projects you’ve left hanging – you know, the ones that you didn’t install, but you’ll get around to fixing, right? If you’ve been in the hydronics trade for a while, and even if you’re relatively new to the field, I’ll guarantee that you have seen a share of less than perfect installations. Summertime, or the “off heating season” months, is an ideal time to return to the scene of the crime to right those wrongs. Here are a few classic examples and opportunities that I have seen and heard about (over and over, in some cases). And even better than just keeping you busy during the dog days of summer, solving these problems for your customers will make you feel good about making a less-thangreat job a much-improved job.

NET POSITIVE EFFECTS The proper placements of the expansion tank and circulator provides a number of desirable effects. Air elimination becomes a non-issue. As long as a proper, working air separator is included, the system will self-purge after the initial fill and power purge. Noise issues related to the inability to rid the piping of microbubbles will also disappear. And properly placed pumps provide positive pressure (try saying that five times fast) as the circulator will add its pressure differential (ΔP) to the static fill pressure differential, which will keep high pressure drop boilers and heat exchangers happy.

Quick Tip:

WHERE’S YOUR PUMP? Top of my list, and perhaps my number 1 pet peeve, is improper circulator placement. This has everything to do with knowing where the system’s Point of No Pressure Change (PONPC) is and then selecting the proper spot for the circulator to reside. At this point, I’d hope that all hydronic specialists, or novices for that matter, understand the value and importance of “pumping away.” An occasional reread of the classic Dan Holohan book Pumping Away can help to keep this concept fresh. Hydronic components may, and will, change over the years, but this concept, generously left to our industry by B&G hydronic visionary Gil Carlson, is everlasting. In the heat of the season, making major piping changes is often not an option. We are sometimes obligated to come up with an ad hoc solution, or to treat a symptom instead of completing the appropriate fix or upgrade, but the summer may afford us appropriate time to go back and make a proper fix. Of course, the key is being competent enough to troubleshoot the issue, and that starts with identifying the proper PONPC.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

It can take some “imagineering” to determine the PONPC when multiple circulators are used with primary secondary piping and low-loss headers (hydraulic separators). A number of suppliers have training materials that can help with piping arrangement options.

BASICS WITH BENEFITS

Another classic hydronic error is the lack of a pressure bypass on multiple zone-valved, single fixed-speed circulator installations.

While you have time in these “off season” months, don’t overlook some simple upgrades that you can suggest to home and building owners. It’s rare to ﬁnd a boiler installation that would not beneﬁt from some pipe insulation. We generally want the heat energy transferred to the living or occupied space, not the boiler room, and on a typical residential hydronic system 100 to 150 bucks-worth of insulation goes a long way to eliminating unwanted piping loss. Did you perform a combustion analysis on the last trip? You should do that on every boiler, be they non-con or mod-con. And leave a copy of the report so that it’s there for reference next time.

UNDER PRESSURE

How about labelling components and generating a piping and wiring schematic for the next mechanic? That’s a nice favour that would save all of us some time if it became standard practice for all of us. And remember, it could be you working on that system again 10 years from now, so it’s not only about making life easier for the next guy (or gal). Having an as-built or some documentation of the system is a big plus. Having your company name on it is better yet.

Adding a Pressure Activated Bypass (PAB) banishes many hydronic demons, but perhaps even better yet is to substitute in a properly sized ΔP smart pump. That’s a circulator with ECM technology and a brain to adjust itself to changing flow and pressure dynamics in the system. When selling this improvement to your client(s), don’t forget to mention the electrical energy savings that they’ll experience over the life of the system.

SHAPING UP THE BUSINESS,

BODY AND SOUL

The off season is also a good time to work on your business as well. Adding some organization to work vehicles can make you more productive moving forward. Maybe it’s time to update the shelves and brackets, adding in tool chargers and containers for small parts. Even a good clean and purge of the winter’s worth of accumulation, inside and out of the van, can get you primed and ready for your next project. Customers also like when you are keeping in touch and show that you are concerned about their mechanical systems, comfort and energy costs. A simple courtesy call to remind them of postponed work, or upgrade options, is time well spent and could evolve into a nice job (or referrals). I also find that factory training is often more enjoyable in the warm months of the summer. The activities associated with them are often less frenzied and more comfortable, unless you ski or dog sled. And it is not always just about work. The dog days of summer are a perfect time to rehab your body and soul as well. Work on home or hobby projects. Take family or friends fishing, hiking, boating, sightseeing to a new yet unexplored location. Visit a festival. Look up an old friend, or plan to attend a school reunion. Read a book – they still exist, and are they viable as ever for learning, and being entertained. And finally, thanks for reading this rambling. I hope you are in the hammock with a relaxing beverage nearby while doing so. 42

NOTE: Boiler fill valves behave properly when connected at the PONPC.

CHECK OUT SOME NEW CONTROLS The upgrading of thermostats and boiler controls is another suggestion that you can make to building owners. Systems with indoor and outdoor temperature feedback can add to comfort levels while reducing equipment cycling. In most cases, they’ll reduce energy costs. Wi-Fi thermostats, and really Wi-Fi anything, makes most techie owners smile. They seem to want to feel that they are not missing out on the Internet of Things (IoT).

It’s A Great Trick If You Can Do It. We did... and it just got better.

Introducing the Aqua3 The best tankless water heater on the market now does heating, too. There’s a reason the Aqua3 uses heat exchanger and component technology typically found on a boiler. Nobody told it that it wasn’t one. Imagine the durability and functionality of a boiler in a compact domestic water heater. High GPM output. Long vent run ﬂexibility. Industry-leading UEF ratings. And home heating. That’s the Aqua3.

James Thomas Blanchett and His Passport to the World

s the industry faces ongoing challenges in recruitment, those tasked with convincing our young folk that a career in the skilled trades could be for them can look to James Blanchett for real-life inspiration. The Prince George, B.C., journeyman gasﬁtter and plumber’s dedication to his career has enabled him to indulge his passions away from the job site – using his time off the tools to travel all over the world. Despite having reached every continent except Antarctica (so far) there is one pin in his map a little closer to home that evokes special memories for him – and it was the job that took him there.

“My favourite project I have ever worked on was actually for a zinc mine in the Yukon,” he recalls. “I was able to practise my love of hydronics on a larger scale there and was there for several months. “It was a job that was so unlike anything I had done before or done since and I loved that challenge. “The Yukon is an incredibly beautiful place as well, which made the experience an even greater adventure for me.” “Join the trades and see the world.” Now there’s a slogan the industry can get behind.

DISTRICT HEATING & COOLING

By Dale Hanscomb

Sheridan College

creates a living laboratory

ith a commitment to optimizing campus-wide energy performance, Sheridan College turned to district heating and cooling as it built an expansive new trades teaching facility at its campus in Brampton, Ont., and even went so far as to incorporate the equipment into its training programs.

52,000 sq. ft. of workshops with high ceilings and large overhead doors to accommodate the industrial equipment used in the curriculum. Special features include a three-storey atrium with skylights, rugged ﬁnishing on the exterior and two accessible roof areas for outside work.

The Skilled Trades Centre (STC) provides in-school training for 1,500 apprentices and post-secondary students each year, preparing them for careers as plumbers, electricians, industrial mechanic millwrights, tool and die makers, welders and general machinists.

The Faculty of Applied Science and Technology (FAST) wanted the teaching facility to serve as a “living laboratory” in which students and interdisciplinary experts could participate in new technologies and design strategies that respond to a changing world, technologies like the tri-generation energy centre that will eventually power all the buildings on the campus.

tri-generation works

A tri-generation plant produces Other Heating/ electricity, heat and cooling in a Cooling Loads series of interconnected processes. By generating electricity on site, using the waste heat to power heating and cooling systems, a tri-gen plant reduces energy consumption and provides a level of independence from the grid. Each Tedom co-generation unit is paired with a JCI absorption chiller, producing enough heat to run the chiller in summer and the radiant heating in the winter. Multiple EnerPro boilers will provide supplemental heat when required. The JCI scroll chiller has a similar effect on the cooling system. A pair of 13,200-gallon tanks hold heated and chilled water, storing energy that is not yet needed. “We designed the system to provide the greatest amount of operational ﬂexibility,” explains David Ng, vice-president of The Aquila Group, the project’s mechanical engineer of record. “The building operator is given numerous options to match the building’s instantaneous load with the optimal system operation.”

Every aspect of STC is designed with sustainability in mind. The building meets the environmental and functional performance requirements of LEED Gold standards for its overall siting, design and construction. Energy performance at 32.2 kBtu/ft2/yr is well below the consumption of typical LEED Gold buildings. The challenge of maintaining comfortable temperatures in a structure with such high ceilings made it a good candidate for radiant. “The workshop’s double-height configuration makes it especially applicable to use the in-floor radiant heating and cooling because we could essentially heat or cool only the occupied area – the first five to six feet – and maintain a lower overall indoor temperature while retaining comfort in the space,” says Ng.

Optimizing performance Hydronic radiant is the primary heating/cooling source, allowing the amount of ductwork and rooftop air handlers to be minimized. This is particularly beneficial in a design where structures and building systems are exposed. A dedicated outdoor air system (DOAS), with a passive desicant wheel, was installed for fresh air ventilation and humidity control. While hydronic radiant systems can be served by a two-pipe design, STC used a fourpipe design with separate circuits that can simultaneously serve different parts of the campus with heating or cooling.

“Flexibility is the key word in this HVAC system design,” say Ng. “We gave facility management a lot of options for running at the lowest operating cost and adapting to changing requirements on the campus.”

The radiant system uses low-temperature heating and high-temperature cooling to achieve the aggressive energy target. “Radiant is very good at dealing with sensible loads and DOAS is very good at dealing with latent loads,” adds REHAU’s Ryan Westlund. “It just takes a little more planning to integrate the two systems for a best-of-both solution.”

To address the risk of condensation, the floors near overhead doors were separately zoned so cooling can be turned off when the doors are opened. Air curtains were installed to prevent conditioned air from flowing out, maintaining occupant comfort. Six dew point sensors were strategically located throughout the STC building to monitor the automated system and keep the humidity in check. The facility also employs hydronic technology outdoors in a snow and ice melting (SIM) system that is installed under the perimeter sidewalks and the receiving dock where the welding tanks and specialty gas are delivered.

FIND THE FIX

LOOKING FOR COMFORT IN THE ZONE So, we’re still crunching some numbers and sorting out some details on that renovated building that now has 32 office spaces es on two floors. Each office has low-temp baseboard heating, and nd is zoned using valves and a thermostat for individual control off each space. You have a pair of boilers, two ⌬P zone circulatorss and have it piped with a low-loss header. 1. If the pipe length from the boilers to the low-loss header and nd back to the boilers is 20 feet, and there are seven elbows, and nd the boiler loss is four feet of head, what is the approximate head loss to size the circulator? or? a) 12’ b) 4’ c) 8’ d) 19.5’ because the total flow is 44 gpm. 2. If the total length of each zone’s piping is 400 feet of 1-1/4” ” pipe pipe, and the heat loss on each floor is 160,000 BTUH, can you deliver all the boiler heat to the new radiators? a) Yes, but the main piping has to be at least 2”. b) No, but on a mild day you might deliver some heat. c) The pipe size doesn’t matter as long as the rads are big enough. d) Yes, but it will fall just outside of the ASHRAE standard of four feet per second, so the pump must be capable of 16 gpm at approximately 23 feet of head loss. 3. Is the pipe size to the DHW Indirect tank capable of delivering 160,000 BTUH at 20°F ⌬T? a) Yes

a) There is nothing wrong with the way it is piped. b) Just insulate the piping. c) Move the supply and return piping to the boiler side of the low-loss header. d) Move the S/R piping onto the supply piping before the low-loss header and install it with closely spaced Ts. e) C & D

The party was a celebration of Wirsbo having sold enough PEX tubing to circle our globe 10 times. That was an amazing achievement in 1990, and Uponor has taken quite a few more PEX romps around our planet since then. Thing is, though, I remember that party mostly because of the chickens.

PEX and installed it under the turf of Olympia Stadium

And, no, I didn’t eat any chicken while there. I ate other things. On Scandinavian Airlines, for instance, they fed me reindeer. That seemed a bit strange, it being just a few weeks before Christmas and me being way up in the air, but my young daughters thought it was hilarious. Oh, and I also ate bear while there. Our waiter gave me a certiﬁcate when I was done and wiping my mouth. It was in Swedish, of course.

But about the chickens. They showed up at the big Wirsbo celebration by way of a delicious talk given by a guy who never got to ﬁnish high school. His name was Thomas Engel, and he was the man who invented PEX.

Wirsbo bought the licence to make Engel-method

grew up on Long Island, New York, where a thousand farmers once grew potatoes on 70,000 acres of rich soil. Grapes grow on much of that land these days. In 1947, while Thomas Engel was still driving a taxi cab, a man named William Levitt visited the Rowehl family. The Rowehls owned a very large potato farm about 25 miles east of Manhattan.

Mr. Levitt offered to buy the whole shebang from them, and the Rowehls quickly realized that growing tract housing was a lot more proﬁtable than growing potatoes, so they smiled and signed the papers. And that’s how Levittown got its start. In the three years that followed, Levitt put up 17,000 nearly identical houses and they all had radiant-ﬂoor heating. He hired Irwin

Jalonack to ﬁgure out the heating for those homes. His daughter, Carol Blum, once wrote to tell me all about him. “My father began his work life as a plumber,” she said, “He then became an HVAC engineer, and, as William Levitt’s executive vice-president, made the decision to use oil-ﬁred, hot-water radiant systems in the houses of Levittown. “The idea was to build an inexpensive

PORTRAIT OF AN INVENTOR Thomas Engel never ﬁnished high school. At 19, he walked out of an American POW camp at Ingolstadt, Bavaria. He worked as a dishwasher, drove a taxi, laboured in a furniture factory, and in construction. And then he invented PEX. He went on to get 120 patents, but preferred selling rights or licences to his inventions rather than become a manufacturer.

He was a millionaire before he was 30. He was also a maker of ﬁne watches, some of which Christie’s Auction House has sold for more than what I paid for my car. He lived to be 88 years old and I will always remember the smile on his face when he told us about his neighbour’s chickens. “Can you make pipe out of PEX so that when the chickens poop on the PEX pipe, the PEX pipe won’t pop?” “Um: Yes!”

During his speech at the party, Mr. Engel told us that if a shoe factory had been present in his vicinity when he invented PEX, we would perhaps today be walking around on shoes with soles made of cross-linked polyethylene. They’d probably never wear out. But it was chickens and not shoes that put PEX on the map. “In our neighborhood, there was a chicken farm,” he said. “And one day, my neighbour asked whether I could make pipes of this material, which he could then lay in the ground. In this way, his hens would have a larger amount of heat and would lay more eggs.” I can imagine the farmer saying, “Thomas, we run hot water though steel pipe to heat the chickens, but when the chickens poop on the pipe, the pipe pops. Can you make pipe out of PEX so that when the chickens poop on the PEX pipe the PEX pipe won’t pop?” Say that ﬁve times fast. “In 1965, I was together with various scientists of the Phillips Petroleum Company in Bartlesville, Oklahoma,” high-school dropout Engel continued. “And we were discussing the crosslinking of polyethylene. “It was possible at that time to cross-link polyethylene by means of highly active radiation. The problem, however, lay not only in the extremely expensive, and somewhat dangerous, equipment, but also because this method of cross-linking was feasible only for wall thicknesses of up to 0.5 mm,” he explained. “The important uses for cross-linking polyethylene would, however, always be for

house that could be run economically. Clearly, building on a slab was the way to go. My father made the decision to go with oil heat and radiant, and then went looking for an oil-fired boiler that was small enough to fit in the kitchen, right next to the other appliances.” York-Shipley and General Electric made those boilers. Today, both Weil-McLain and Peerless make boilers specifically designed to fit in the footprint of those original

thick-walled parts, having a wall thickness of one to 10 mm.” After experiments with an extruder, and then lasers, he decided in favour of a compression method, with intermolecular friction. “The cross-linking of the molecules would have to be easier if I could heat them rapidly and bring them closer together by high pressure, so as to then cross-link them in the presence of a catalyst,” he said. “Years of intensive research followed, ﬁnally culminating in success. The result was a handful of glittering white plastic, which came out of the autoclave.” With that small treasure in his pocket, Engel ﬂew back to Phillips Petroleum in the U.S., where further analysis was carried out. “We found I had actually obtained 97% cross-linking. And as a result, the thread-shaped chains of molecules connected directly to each other. We heated the polyethylene and the plastic simply would no longer melt into a shapeless mass. The joy was immense, but what was to be done with this new plastic, and into what could it be fabricated?” he pondered. Engel then explained how he travelled from one chemical company to another in the hope of selling a licence, but the answer was always the same: “That’s marvelous, but what do we do with it?” Enter the chickens. They led Thomas Engel to Wirsbo because Wirsbo had been making pipe since the 1600s, and chickens were pooping back then, too.

Levittown boilers. To pipe them, you need a shoehorn. But then, if you can pipe in Levittown, you can also pipe inside a clothes hamper, so there’s that. Those who work in Levittown these days tell me that only about ﬁve per cent of the radiant systems are still working. Most have been replaced with ﬁntube baseboard. Levitt didn’t bother with vapour barriers or slab insulation of any sort. Nowadays, one way to tell which radiant systems are still

working is to wait for snow. If the system is working, there won’t be any snow within ﬁve feet of the house, and the tulips will be growing. Maybe even some potatoes.

f there is one overriding theme for the 2019 truck markets, it has to be the return of the midsize pickup.

Five years ago, only Toyota and Nissan still built midsize trucks, but Detroit is back in the game, and sales are brisk. GM is offering the Canyon and Colorado twins, while Ford has brought back its much-missed Ranger. Jeep is also in the mix with its first new truck in 28 years, the Gladiator, and rumours of a pending new Ram Dakota are rampant. Over in the bigger toys, HD trucks are getting makeovers and reaching ever higher weight and power numbers. Personal driver assistance features are becoming the new standard and there are even electric options on the horizon.

CELEBRITY ENCOUNTER By Adam Freill

PICKING FAVOURITES What’s Ron’s pick for the car he wants to be in, on or off the track? The Corvette ZR1. “With 755 horsepower, it’s an awesome car, and nice on the street. It is an absolute treat to get it on the track, especially with the Michelin Pilot Sport Cup 2s.”

In the driver’s seat, with

Canadian Tire Motorsport Park Location: Bowmanville, Ont. Opened: 1961 Grand Prix Circuit: 2.459 mi (3.957 km) Turns: 10 Additional tracks: Driver Development and Karting Social Media Handle: @CTMPOfﬁcial Website: canadiantiremotorsportpark.com

An icon in racing, and a champion on some of racing’s biggest stages, Ron Fellows is also a welcome and engaging host, sharing insights with thousands of drivers each year at his performance driving academies and welcoming guests to Canadian Tire Motorsport Park. Fellows made time to chat with us about sport, business and the importance of passion and perseverance – something that he discovered in himself when a key was turned at a memorable race.

RON FELLOWS

Photos by John Packman.

The year was 1969 – 50 years ago – and Ron’s uncle brought Ron and his brother to the Canadian Grand Prix in Bowmanville, Ont., at a track then known as Mosport.

“It was absolute magic,” says Fellows, reﬂecting on the fact that his love of the sport started at the very track that he is now a partner in, Canadian Tire Motorsport Park. “Fast cars and competition was in the soul, but it needed something to bring it out,” he says. “That was coming here and seeing the Formula One cars. From that moment on, it was, ‘Forget about hockey.’”

IT TAKES MONEY TO RACE Many people don’t realize that much of racing occurs off the track, but the price to play can be significant so drivers and teams are constantly seeking sponsors and spending time on marketing. “The desire to want to compete was really, really powerful, so out of necessity, you learn how to make it happen,” says Fellows. “Not coming from a wealthy family background, it was trying to figure out how to make as much money as possible, working, and then trying to find sponsors, which is way easier said than done.” After getting a taste of winning in karting, Ron moved into Formula 1600, a logical, but expensive, progression. “I went broke trying to do that,” he admits, but his perseverance kicked in, and he found ways to work through the expenses. “I spent 10 years working in construction, and three or four years working as a machine operator doing trenching for small gas pipeline work. That was my day job.” By the mid-80s, a number of new racing series emerged, with relatively inexpensive vehicles and attractive prize money. “My timing was pretty good,” he says of his entry into the Player’s GM Series, which featured showroom stock Camaros and Firebirds. “You literally drove them to the track and raced them.” His break, he says, came from one of two races that was televised that season. “I won the one in Quebec, and things changed after that,” he says. “Not only did I learn how to race in that series, but I also learned how to do some marketing. It was trial by fire, but I was really fortunate along the way to find people who believed in my ability and were able to help me financially.”

From the driver’s seat to the boardroomm“As a racing driver,” says Fellows, “you are part of a team focused on the goal of winning races, but ultimately, the driver is the one that has to deliver. You want to be the guy. Give me the ball.

Driving tips, from a pro “You’ve got to stay attentive,” says Fellows about staying safe behind the wheel, be that in a Corvette on the track or in a work van on the highway. “A lot of that comes from a simple thing like seat position. You are not lounging at home. You are driving a multi-thousand-pound vehicle at a speed that you are putting yourself and others potentially at risk if you are not paying attention. “Make sure that you are comfortable to the point where you can see what you are doing; keep your eyes moving; keep your eyes up; and always have an out – an outlet you can take in an emergency.”

Rebuilding a legacy “We have great tracks here in Canada,” says Fellows. “There’s a reason why we produce, as a country, a disproportionate amount of great drivers. It is because of tracks like this [Canadian Tire Motorsport Park]. If you can go fast and win here, you can go fast and win anywhere.” The track, he says, is a bucket-list track for drivers around the globe. “It is world famous, world-class. The beauty of the racing surface is long, fast corners, and elevation change; it is super challenging, and drivers love it,” he explains. “The layout is the same as when it opened in 1961. Is it wider and safer? Yes, but the apexes are in the same place. That’s the beauty of it.” While the layout is the same, the track amenities certainly are not. “We really felt, as a group, if we could bring this facility into the 21st century, in terms of our ability to host not just spectators, but corporately, then it’s a bit of a Field of Dreams – rebuild it and they will come back.” Following major upgrades every winter from 2011 to 2015, the facility now has a 24,000-square-foot main building that can host corporate sponsors, weddings and special events year-round, as well as improved karting and development tracks. “We’ve been growing quickly. This is not the same place it once was.”

OR NOT TO

clean

THAT IS THE QUESTION!

emember the “Good old days” of furnace servicing, when we had ribbon burners and cast-iron heat exchangers? Back then it was easy to know which parts of the equipment needed to be cleaned. Armed with our brushes, vacuum and mirror we would scrub the heat exchanger, oil the motor, tighten and adjust the belt and conduct our safety checks. With the invention of the inshot burner and the multi-pass heat exchanger, our processes have completely changed. Rarely will you hear manufacturers speak about cleaning the heat exchanger anymore, but does that mean we don’t need to clean anymore? I say no. There are still numerous things that we need to ensure are cleaned, but the processes have changed, so we must evolve to remain relevant. For example, we all look at the flame rod, but do we think about the face of the burner? The flame rectification circuit must go to a reliable ground so any rust build-up on the face of the burner can produce erratic readings.

That’s an item to have on our cleaning checklist, but there’s more to do during equipment servicing than just cleaning. We need to be checking for airﬂow, electrical continuity, refrigerant charge, proper combustion, temperature differentials, and much more. As the equipment continues to change and improve, so too must ﬁeld technicians. Manufacturers have made changes to ensure that HVAC equipment will operate correctly despite facing some pretty intense conditions at times, but to do so these units need regular, and proper, maintenance. What used to be done 20 years ago is not acceptable today. A maintenance contract can no longer simply be a cleaning service, rather, today’s maintenance contracts should have us checking the equipment for things that could go wrong before they do, and we have the tools available to allow us to do just that, if we choose to use them.

DON’T TAX THE MOTOR The blower motor is a piece of the equation that often gets overlooked. As motors have evolved, technicians often believe that these are pieces of equipment that they no longer need be concerned about. That could lead to problems, however If you look at the electronically commutated motor, it ramps up or down based on settings. If we fail to pay attention to any buildups on the blower wheel, we’re asking the motor to work harder. In the courses that I teach, I often ask students, “What do you use to eat soup?” The answer is, as expected, “A spoon.” When asked, “Why not a knife?” they laugh and say because they will not be able to get any of the soup into their mouths. Similarly, when the blower wheel gets clogged with dirt, it is unable to lift any air into the ductwork. This becomes especially evident when you run a PSC blower motor and add lots of static pressure. When this happens, the amps actually go down. Why? Because the blower motor is not doing any work. This same thing can happen with an ECM. The motor will ramp up to try and compensate for the reduced lift of the blower wheel, causing the motor to work harder and the watts to go up.

HVAC CHECKING THE CONDENSER

COMBUSTION MATTERS An important maintenance check for furnaces is to ensure we are achieving proper combustion. One of the most important, but probably most underutilized tools, in our toolbox is the fuel gas analyzer. This could be because back in the day, when we had the ribbon burner, it was relatively simple to look in at the flame and make an adjustment to the air shutter. Since the inception of the inshot burner, it has become impossible to simply view the flame, and yet many technicians still think they can look at the flame without any tools and see incomplete combustion. This is simply not true. Today every technician should be equipped with an analyzer. This tool enables them to see the condition of the air after a completed combustion cycle. Being able to see the amount of excess air before and after the circulation blower turns on can be one indicator that there is a problem with the heat exchanger. This fantastic tool can also tell us the condition of the flame, such as if it is over- or under-fired.

With the invention of higher SEER equipment, the temperature difference across the outdoor coil has become increasingly lower, while the coils have grown significantly bigger. As the demand for smaller footprints grows, some manufacturers are doubling up the coil rows, or even looking toward microchannel as an option. For any of these coils to work, no matter the application, there must be adequate airflow across them. Even the smallest amount of dirt or debris can cause the airflow to change, which will impact its efficiency. It is therefore imperative to ensure that the airflow is correct before beginning any checks on the equipment’s proper operation. Just because the charge is correct and the AC seems to be working fine, if you are not checking its airflow, an equipment fault can easily be missed. There are several ways of checking airflow during maintenance calls, but whether we are looking at the furnace or the air conditioning unit, we need to make sure we do more than just dust off the outside of the unit and call it a day.

KEEPING CUSTOMERS During the cooling season, we need to ensure that our customers understand the need to have their air conditioning units maintained, and that this should be performed by a qualiﬁed individual for safety and accuracy. Most modern AC units have a sealed condenser fan, so there is no lubrication required, but the condenser and line set should still be inspected for signs of oil leaks. Also check the unit for proper voltage and amperage. When it comes to the outdoor coil, it is prudent to remember that in most units air is drawn through condensers, so when washing the coil, backﬂushing will keep debris from being

cool

driven deeper into the coil, which could negatively impact its performance. With regards to the indoor coil, airflow is king, so ensure the proper volume of air is flowing across the coil. And be mindful that there is a potential for leaks when you hook up gauges. In some cases, non-invasive testing can be used to ensure the unit is charged correctly and operating to the manufacturer’s specifications.

Smartphones and tablets continue to change the way we communicate. In addition to having a number of options for communicating with others (e.g. phone calls, emails, texting, discussion forums via the internet, etc.) smart devices can also be a very useful tool for our day-to-day business activities.

Some apps are available at no charge, but don’t be surprised if a free app displays ads during its use, unless a fee is paid.

A challenge when diagnosing failures with a technical support person who cannot be at the equipment location has always been describing what you are seeing. Being able to share images or even videos with the support person can save a lot of time.

Among the apps that I ﬁnd useful are the ones that can be used to look up the saturation pressures and temperatures for a refrigerant.

Electronic manifolds began to ars enter the market several years ns of ago. The earliest generations these manifolds were typically ally connected via cables to pressure essure transducers and temperature re sensors for the purpose of checking superheat and subcooling. In order to be able to do this, the manifold contained a list of refrigerants to choose from. With this technology, also came the opportunity to record operating conditions to support troubleshooting, or even to document the system operating conditions. Some of the more recent versions use wireless connectivity, like Bluetooth, to connect sensing devices to software. Most of these new devices have a data-logging feature. Along with battery life expectations, the practical communication distance between the host device and sensors has also improved over the years, making the newer manifolds that much easier to work with.

BUILT-IN DIAGNOSTICS Itâ&#x20AC;&#x2122;s not just our phones that got smart over the past decade. There are now many smart controllers that can aid in equipment troubleshooting and servicing. For example, some manufacturers provide controls that monitor compressor operation, to ensure that the compressor stays within its envelope. With conventional protection modules, their main purpose is to meet local and national electrical code requirements, however, the newer extended-function modules not only meet the code requirements, but also provide the best protection available for the compressor. This is because they can be conďŹ gured for a particular compressor model number, refrigerant and voltage. 0 8 . 1 9

With built-in data-logging features, modules record the operational conditions, warnings and alarms, along with other useful information such as number of starts, number of running hours, and the percentage of capacity at which the compressor is operating. Also, with the number of interconnecting wires between the main control panel and compressor signiﬁcantly reduced, control wiring is less confusing and easier to trace – and it also simpliﬁes installation. For those who want to fully exploit the potential of these modules, Modbus can be used as a communication link to merge compressorlevel information with a central controller. This gives the user the ability to view the operating parameters of a system at the various hardware levels.

PROGRAMMABLE LOGIC CONTROLLERS Growth of these devices has been on the rise for several years now. Most modern industrial-grade chillers and other HVAC equipment use PLCs because of the many advantages that they bring, including the ability to monitor operational information at the system level and accommodating remote connections for viewing, and perhaps even troubleshooting. When using PLCs in conjunction with smart controllers, like at this Zarky’s in Hamilton, Ont., the user has access to a lot of information on one screen. By connecting smart component devices, such as compressor monitors, variable speed drives, and communicating oil-level regulators, to the PLC and programming it accordingly, you can have a complete system for directing the sequence of operation for a system, while offering monitoring, diagnostics, alarms, remote connect, and more.

Some advanced modules may not wait for an overload condition, proactively working to avoid an overload by making adjustments to the capacity control and auxiliary cooling, such as head cooling fans and liquid injection.

Be sure to tune in next time… These are just a few of the changes that have hit jobsites and equipment over the past little while, and there are plenty more, some of which we will continue to explore, in the next edition of Mechanical Business.

Building trust with every action I

A scientiﬁc perspective According to trust researcher Adam Waytz of the Kellogg School of Management, the four key components of trust are integrity, competence, predictability and benevolence. Other studies demonstrate that from a science point of view, the hormone oxytocin increases trust by suppressing the neural systems that regulate our fear of betrayal. In other words, gain trust and they let their guards down. While not everyone believes that a whiff of a hormone will build trust among strangers, being trustworthy in business does give you a leg up on the competition. Grounding our business actions by doing things like the themes outlined here can go a long way to building trust-based relationships that will last for the long term.

n a timee of hyper-engagement through traditional nal and social media, in which rs critically examine what is consumers presented d to them, there is an everexpandingg list of competitors, all vying for customer attention ding dollars. So, and spending how do we convince ences our audiences that we’ree eir worth their ce? conﬁdence?

The answer: Show, don’t tell. Avoid dropping ads with headlines that say you’re “Trusted since 1980” or proclaiming “You can trust us!” As one client mentioned to me recently, “We don’t need to ask our customers to ‘trust us’ as long as we are demonstrating why they should.”

Creating a trust culture Now, more than ever, building trust with customers is a key to business success. Thankfully, there is plenty of fascinating literature about the psychology of trust and how to build it in the people we meet.

Focus on your employees – This year, the Edelman Trust Barometer, an annual survey of thousands of people across North America, showed that people now trust their own employers more than the media, government, NGOs, or other businesses. They have conﬁdence in what’s closest to them – things they can see, control or feel empowered to change. Our employees can be our greatest spokespeople – or our worst PR nightmare, because once we lose their trust, it’s tough to gain it back. How do you focus on your employees? Invest in them through training and professional development. Ensure that you have systems in place to promote healthy work-life balance. Provide opportunities to receive and give feedback. Say thank you once in a while. And strive to keep them. Reduced employee turnover shows your staff and your customers that your organization has stability.

Promise what you can deliver, and deliver what you promise – This one may seem like a no-brainer, but in the desire to sound better than the competition, it can be easy to overpromise.

I’ve learned this is especially true in my business, especially since new, highly specialized areas of marketing are emerging every day. You can’t “fake it until you make it.” Customers won’t be impressed if you don’t sound credible, or can’t meet your own launch deadlines or service guarantees. Stay in your lane, and focus on improving internal processes so that you can meet or even over-perform what you promised.

B u s i n e s s

0 8 . 1 9

Fix your mistakes properly – Mistakes will happen in any business. Owning it and taking responsibility can build a more solid trust foundation with a customer than if it hadn’t happened at all, because it demonstrates integrity. Deal with the error quickly, avoid laying blame, evaluate it carefully and circle back with the customer — not only to make sure they’re satisﬁed with the outcome, but to communicate how you’ve changed your business to prevent the problem in future.

Communicate effectively

Let your customers and employees know what’s going on. They want to know that your organization values more than a large proﬁt at the end of the year. Blogs and newsletters are great ways to share internal processes, training, community involvement, and more. Tell the stories of your people, your customers and your community. This humanization will help your customers see the faces behind your purpose, fostering trust and connection.

Engage in the broader community

Three-quarters of people believe businesses can make money as well as improve society. In other words, they want companies to take a stance on public issues and important causes, and commit to them. What are the values that drive your organization? How can you support the individuals and systems in your industry? For example, restaurants can support local food networks, and developers can support affordable housing initiatives. It’s important to mention here that, while one-time ﬁnancial donations are an aspect of corporate social responsibility, there is an increasing desire in customers to see organizations investing in “systems of change.” This may mean a long-term partnership with a nonproﬁt, a change in your value chain and sourcing, or even a shift in organizational goals and mission.

Focus on retention – You should always be thinking about customer retention and follow-up. It makes good ﬁnancial sense, as, according to research, returning customers spend a third more than new customers. Not only that, the more loyal a customer is to you, the more likely they will trust your brand and recommend your business to their friends and family. What do retention programs look like?? It starts with great customer wservice. Beyond that, it can mean followup emails, referral/returning customer promotions, loyalty programs, newsletters, informative blogs and g more. It’s important to offer something of value to the customer each time they return.

The seven deadly sins of CROSS CONNECTION P

ol olluted or contaminated fluids co (and sometimes other materials) materia can enter drinking drrinking water piping through backflow and or back-s back-siphonage in the water system. In other wate words, the water is word flowin flowing in the reverse direction to which it was intended. In most cases this reverse flow cannot be seen when it occurs. These cross connections, whether actual or potential, can be eliminated through the use of an air gap. When an air gap is not possible or appropriate, cross connection risk can be reduced by using approved backflow prevention devices and assemblies. Depending on the hazard of the connection (minor, moderate or severe) an appropriate approved backflow preventer device or assembly would be installed to protect the potable water system.

SIN NO. 1: THE HOSE BIBB

A connected hose with an open end can be immersed into mixing pails, tubs or M e c h a n i c a l

For more information regarding backﬂow protection please consult the current National Plumbing Code, CSA B.64.10 standard and the Canadian Cross Connection Control Manual.

SIN NO. 2: THE SERVICE SINK FAUCET Normally found in schools and commercial buildings, the service sink faucet can create a cross connection through the faucet when a hose is attached. If the flexible service sink hose is immersed and filling a pail with cleaning chemicals, the potential exists for backflow if the water pressure is lost in the building.

Corrective action: Install an approved hose connection vacuum breaker on the service sink faucet or switch out the faucet for a modern one with a built-in atmospheric vacuum breaker.

sinks, or may be laying on the ground in a pool of water, which can create a potential or actual cross connection allowing fluids other than drinking water back into the building water supply.

The ever-popular hose bibb, found in homes and buildings throughout Canada, is thought to be the most common offender that can lead to a cross connection.

Find out more

B u s i n e s s

If a building loses water pressure, perhaps from a water main break or if the building’s water is turned off by a repairman, the contaminated contents of the pail or pool of water on the ground can be backsiphoned into the drinking water lines of the building. When the water pressure is restored, the contaminated water is now distributed through the drinking water system.

Corrective action: Properly install a hose connection vacuum breaker to control the cross connection, or use a wall hydrant (frostfree hose bibb) with a built-in vacuum breaker. 0 8 . 1 9

SIN NO. 5: BOILERS SIN NO. 3: THE Y FITTING This use of Y fittings, a rubber hose that gets connected to the hose thread of a service sink faucet to provide two outlet valves, is very concerning, and unfortunately happens too often. Once the service sink’s hot and cold handles are opened, the cleaner has two outlets rather than one to use at the sink. A problem can occur, however, when the cleaner does not close the hot and cold faucet handles, only stopping flow at each end of the Y.

This boiler has the correct RP backﬂow preventer installed, but an illegal bypass means the potable water supply is not protected. Most heating systems have a connection to a potable water line to maintain the boiler water pressure. An approved backflow preventer must be used to protect the potable water where a direct water connection is used. If chemicals are used in the heating system’s fluids, to protect the boiler from corrosion or freeze ups, a backflow preventer that is approved for this severe hazard application must be used.

Corrective action: Install an approved RP backflow preventer This puts constant pressure on the atmospheric vacuum breaker that is typically found in the faucet spout. These atmospheric vacuum breakers are designed for a maximum of 12 hours of continuous use, after which they can get frozen in a closed position, becoming inoperative. A failed atmospheric vacuum breaker provides only a false sense of protection.

Corrective action: Remove the rubber Y fitting immediately and inform the person responsible about this potentially dangerous connection.

for a direct water line connection, or eliminate the direct water line connection by using a separate, self-contained pressurized boiler water supply.

SIN NO. 6: TOILETS AND URINALS Water closets typically have direct connections to the potable water supply, and must therefore use an approved backflow prevention device on the plumbing fixture to protect the water system from potential siphonage of fecal material and urine back into the potable water lines.

Corrective action: A residential tank style WC will use a ballcock

SIN NO. 4: CHEMICAL DISPENSERS Wherever cleaning chemicals are added to a water system, a severe hazard is created. An approved backflow preventer must be used to protect from these chemicals backflowing and entering the drinking water system.

Corrective action: The installation of an approved Reduced Pressure Principle Assembly (RP) backflow preventer to isolate the water lines serving the chemical line connections. Alternatively, the installation of an approved air space vacuum breaker.

He currently oversees the national “Bad and Ugly” cross connection photo contest for the Western Canada Section of the AWWA. You can email him at wilson4@telusplanet.net.

with an approved anti-siphon device. A commercial flushometer style toilet or urinal will use an approved atmospheric vacuum breaker to suit the flushometer valve.

SIN NO. 7: SINKS, BASINS AND TUBS Kitchen sinks, wash basins and bath tubs all have hot and cold potable water connections and are designed to use an air gap, considered to be the most effective method of preventing a cross connection. The air gap is the actual open-air space below the outlet of the faucet spout and the flood level rim of the plumbing fixture it serves. This feature physically prevents any pollutants or contaminates from entering the faucet spout and water lines by back-siphonage. However, the addition of a hose to the spout of the plumbing fixture can circumvent the air gap.

Corrective action: Ensure the air gap height is a minimum of 2 times the effective opening (measured as a pipe diameter) of the faucet spout and never less than 1” in height. If a hose is connected to a plumbing fixture spout and there is no approved atmospheric vacuum breaker installed, the hose must be removed to re-establish the air gap protection.
