Making Q&E connections with Q&E expansion tools Note: All standard Uponor expander heads are compatible with the M12 and M18 tools. Uponor expander heads will not auto-rotate on the Milwaukee tools (only Milwaukee expansion heads will auto-rotate on the M12 and M18). Milwaukee heads are not compatible with Uponor tools. Milwaukee heads are easily distinguished by color coding and the Milwaukee logo.

Important! When making a Q&E connection, be sure to follow the guidelines for the tool you are using in your application.

1. Square cut the PEX pipe perpendicular to the length of the pipe. Remove all excess material or burrs that might affect the fitting connection. 2. Slide the Q&E ring over the end of the pipe until it reaches the stop edge. If using a Q&E ring without a stop edge, extend the ring over the end of the piping no more than 1⁄16” (1mm).

3. Milwaukee Q&E expansion tools come with built-in auto rotation. If using a Uponor Milwaukee expansion head, simply hold the pipe and tool in place while holding the trigger to expand the pipe. The head will automatically rotate to ensure the pipe is evenly expanded. 3

Note: Do not force the pipe onto the expander head. Ensure the expander head is rotating during each expansion. Note: The required number of expansions can vary with ambient temperature. Uponor recommends making a test connection first to gauge the pipe’s reaction time. Note: Only Milwaukee tool auto rotates.

4. Continue expanding until the pipe and ring are snug against the shoulder on the expander head. See table below for the recommended number of expansions for each pipe size.

Important! Rotating the tool between expansions will provide smooth, even expansion of the pipe. Failure to rotate the tool will cause deep grooves in the piping, which can result in potential leak paths. 5. After the final expansion, immediately remove the tool and insert the fitting. Ensure the pipe and ring seat against the shoulder of the fitting.

Important! Only perform the necessary number of expansions. DO NOT over expand the pipe. You should feel some resistance as the fitting goes into the pipe. If you do not feel any resistance, the pipe may be over expanded and will require additional time to shrink over the fitting.

Making Q&E connections with Q&E 110V REMS expansion tool

1. Square cut the PEX pipe perpendicular to the length of the pipe. Remove all excess material or burrs that might affect the fitting connection.

2. Slide the Q&E ring over the end of the pipe until it reaches the stop edge. Extend the ring over the end of the pipe no more than 4â &#x201E;16â&#x20AC;? (4mm). 3. Slide the expander head into the pipe until it stops. Full expansions are necessary to make a proper connection.

4. Press the trigger to expand the pipe.

5. Release the trigger, remove the head from the pipe, rotate it 1â &#x201E;8â&#x20AC;? (3mm) turn and slide the head back into the pipe. Continue expanding and rotating until the pipe and ring are snug against the shoulder on the expander head.

6. After the final expansion, immediately remove the tool and insert the fitting. Ensure the pipe and ring seat against the shoulder of the fitting.

Troubleshooting Q&E connections 1. Ensure the Q&E expander tool is properly maintained and in good working condition. 2. Make sure the expander head is securely tightened onto the tool. 3. Frequently check that the expander head is securely tightened to tool. 4. Ensure the segment fingers are not bent. 5. Remove excess grease. 6. Check the fitting for damage. Nicks and gouges will cause the fitting to leak. 7. Make sure the last expansion is not held in the expanded position before inserting the fitting. 8. If using a manual (hand) expander or REMS tool, rotate the head 1/8“ (3mm) turn after each expansion.

Cold weather expansions Temperatures affect the time required for the piping and ring to shrink onto the fitting. 1. Warming the Q&E fittings and Q&E Rings reduces contraction time. Put fittings and rings in your pockets prior to installation to keep them warm. 2. Make Q&E connections at temperatures above -15°C (5°F). 3. Fewer expansions are necessary in temperatures below 4.4°C (40°F). 4. Perform a test connection for each pipe size when temperatures differ from day to day, keeping note of number of expansions to make a snug fitting connection.

Power tool maintenance Keep your tool, battery pack and charger in good repair by adopting a regular maintenance program. Each month: • Remove the expander head and soak in degreasing agent to remove grease from between expander segments • Wipe expander cone with clean, dry, lint-free cloth Re-lubricate: After six months to one year, depending on use, return the tool, battery pack and charger to a Milwaukee service facility for: • Lubrication • Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.) • Electrical inspection (battery pack, charger, motor) • Testing to assure proper mechanical and electrical operation If the tool does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the tool still does not work properly, return the tool, charger and battery pack, to a Milwaukee or REMS service facility for repairs. Cleaning: Clean dust and debris from charger and tool vents. Keep tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean the tool, battery pack and charger since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use flammable or combustible solvents around tools. Repairs: For repairs, return the tool, battery pack and charger to the nearest service centre.

The following products are recommended with Q&E PPSU products PTFE tapes according to EN 751-3 FRp Loctite 5061, Loctite 5331, Loctite 516

Special notes for pressure testing Q&E joints Uponor Q&E joints depend on the elasticity of the Uponor PEX material to form a tight joint. At low temperatures, the elasticity of the material is reduced. This means a longer period of time for the joint to become tight. The pipe will always shrink back to it’s original dimensions and the joint will always eventually become leak tight.

The following products are strictly forbidden with Q&E PPSU products Ever Seal Thread 483 Loctite 55, Loctite 518, Loctite 542, Scotch-Grip Rubber 1300, Scotch- Grip Rubber 2141 Scotch-Grip Rubber 847, Rector Seal 5 Rite-Lock, Selet Unyte

Please observe the minimum waiting time after making the last joint before making the system pressure test. The joint can be pressure tested after 30 mins at ambient temperatures above 5OC. At lower temperatures allow more time before testing the joints, as shown in the table below. The maximum test pressure for Uponor PEX pipe with Uponor Q&E joints which must not be exceeded is 18 bar.

Expansion compensating devices No special expansion compensators are needed if: •The water pipe is supported and anchored at a maximum spacing of 6m. •The water pipe is run in a conduit where the necessary space for expansion is provided in the gap between water pipe and conduit. •The pipe is run in long lengths on a rack.

However, in installations allowing the thermal expansion, where the pipes are expected to stay straight, expansion campensators should be used.

Calculation of a flexible arm and expansion loop The flexible arm should be long enough to prevent damage, and support clamps should be placed sufficiently far from the wall to allow for longitudinal thermal expansion. Use the formula below to calculate the minimum length of the arm. When designing an expansion loop it is preferable to design it so that I2= 0.5I1. In case the flexible arm is calculated according to the equation below:

Example: An Uponor PE-Xa pipe with an outside diameter (OD) of 50mm is installed with 30m between anchor points. The hot water it carries is 70OC and the ambient temperature is 20OC. Calculate the length (LB) of the flexible arm. Calculate the thermal length variation by using the diagram. From the graph, the thermal expansion at 20OC is 2.5mm/m, while the expansion at 70OC is 12.5mm/m. The expansion of the pipe will be 12.5-2.5 = 10mm/m when carrying water at 70OC. The total thermal length variation in this case is: ∆L - 10mm/m x 30m = 300mm.

Pressure testing Hydraulic pressure testing shall be undertaken in accordance with BS EN 806-4:2010 or Water Regulations 1999 using cold potable water BEFORE the system is taken into operation. Hydraulic pressure testing is not a substitute for the correct installation of the PEX pipe and associated ﬁttings. It is essential that the correct size ﬁttings are used for the pipe and that thermal movements are taken into account when installing the pipe. The test pressure applied to the system should be 10 bar or 1.5 x the maximum pressure rating of

the lowest rated component in the system. The maximum test pressure applied to Uponor Q&E pipe should not exceed 18 bar at 20°C. Other equipment in the system, such as boilers, cylinders, radiators, valves, etc. should be checked with the manufacturer as to their maximum pressure rating BEFORE any pressure test of the complete system is performed. If in any doubt, isolate all other equipment before pressure testing and only test the Uponor PEX pipe with the Uponor Q&E joint or Uponor compression ﬁttings. Air testing is acceptable.

Pressure testing graph 1.5

Method • Vent and ﬁll the system with water. • Visually inspect the whole system for leaks. • Pressurise the installation to a test pressure of not less than 1.5 times the maximum working pressure. • Apply the test pressure by pumping for a period of 30 minutes. Inspect for leaks. • Reduce the pressure in the pipework by bleeding water from the system to 0.5 times the maximum working pressure. • Close the bleed valve. Visually check for leakage and monitor for 90 minutes. If there is no reduction in pressure the system is regarded as leak tight. • Flush the system as required.

Other considerations Gas

Anti-freeze

Uponor PEX pipes must not be used to carry gas inside a building or to carry compressed air.

Ethylene glycol central heating anti-freeze mixtures have no adverse effect on Uponor PEX pipes.

Corrosion inhibitors Corrosion inhibitors should be used in central heating systems in the normal way to prevent corrosion of steel radiators and other components. Uponor PEX pipes are not affected by proprietary anti-corrosion compounds such as Fernox or Sentinel at the normal recommended dosing levels.

Where systems are left with residual water in unheated and unprotected buildings in freezing conditions, there is a risk of frost damage to the pipe. In all cases where there is a risk of freezing, add a glycol-based antifreeze to the water to avoid ice damage to the pipe. The % mixture should be in accordance with the particular brand of anti-freeze being used and the expected temperature level. www.uponor-qe.com

After freezing conditions have lifted and before the system is started, the anti-freeze mixture should be fully flushed out of the loops and disposed of properly in accordance with local regulations. Painting Uponor PEX pipe is specially manufactured in white to obviate the need for onsite painting. It is not recommended to paint Uponor PEX pipe.

Uponor Q&E storing and handling guidelines Refer to the Uponor Q&E plumbing installation guide for a comprehensive list of guidelines.

• Do keep PEX piping in the original packaging until time of installation. • Do not store PEX piping outdoors. • Do not use Uponor piping where temperatures and pressures exceed limits. • Do not weld, glue or use adhesives or adhesive tape with Uponor piping. • Do not apply open flame to Uponor piping. • Do not install Uponor piping for any gas appliances. • Do not install Uponor piping within 12" of any recessed light fixture unless the piping is protected with suitable insulation or the light is Insulation Contact (I.C.) rated.

• Do not install Uponor piping within 5 ft. of direct view from fluorescent lighting without sleeving the pipe with UV-blocking material.

• Do not solder, braze, weld or fusion-weld within 18" of any Uponor piping in the same water line. Make any heat-related connections prior to making the Q&E connection.

• Do not spray on or allow organic chemicals, strong acids or strong bases to come into contact with Uponor piping.

• Do not use petroleum or solvent-based paints, greases or sealants on Uponor piping.

• Do not use Uponor piping for an electrical ground. • Do not press Q&E brass fittings (i.e., copper press). Note: When transitioning from PEX to other piping materials, follow the appropriate installation instructions for that product.
