• Design

• Reliability

• Efficiency

Research conducted by the Engineering Department have resulted in units with a high design efficiency and optimum performance. The selection of prime components and our quality and control system ensures performance and reliability. All main components are rigorously tested and qualified before being installed. Each unit design has gone through long hours of rigorous testing to ensure reliability, durability and quality of the entire system.

All structures are made of galvanized steel sheet, coated with electrostatic baked paint to ensure long durability and no corrosion in any weather, such as prolonged direct sunlight, rain and wind.

Our units are designed to meet the needs of any project. Our featured intelligent process controllers and smart temperature sensors provide maximum performance while saving energy.

All units are designed to fit a reduced installation space, eliminating thus large installation areas. We only use high quality components to ensure durability and reliability even under harsh environmental conditions.

The system automatically modifies the operation mode to maintain optimal conditions, making it very easy to operate.

All units have a compact and sturdy structure while maintaining a slim profile.

NOTE: For applications in tropical climates our units are coated inside and outside with Corrosion Protection Our products have efficiency certifications from AHRI and electrical certifications from ETL, we also comply with all industry safety standards. We are members of the American Society of Air Conditioning, Refrigeration and Heating Engineers (ASHRAE). To support our commitment to customers and our stakeholders our units have a 1 year mayor warranty after start up, . Our units use R410A refrigerant, which is harmless to the ozone layer and is not toxic or flammable, even in case of leakage. Finally, the heat exchanger efficiency and modular design allow for an easy and quick installation.

All temperature sensors are calibrated and set at the factory before shipment. Start up has to be performed by a qualified technician, during the initial startup steps the unit will be set to local conditions and all points of operation will be reviewed. Once the unit is set, operation is a matter of pressing the start and stop button and making sure that the unit operates properly, after this the unit will operate automatically, starting itself according to the demand of the cooling system and local conditions.

• Flexibility The units have smart processors and sensors to automatically control the temperature at optimum operating conditions. The units were designed to mate with each other and be combined to meet different load variations (tandem installation). You can combine up to 8 modules; these combinations may be done with chillers of different capacities ranging from 3 to 200 tons. Capacity varies depending on the number and type of units.

FEATURES / BENEFITS

All external paint has been tested in a saline chamber and is rated at 1,500 hours proof. Compressors and heat exchangers ensure high equipment efficiency capacity. The water pump is specially designed to work properly and with minimal vibration and noise.

• Communication

• Installation

• Factory Testing

The units can be controlled independently as a single unit (individual mode), or they can be connected to a central control unit (tandem mode). Operation and user input is done via a color 7" touch screen.

The units have been designed for a field-friendly installation. Screw type connections provide easy installation of the water pipes, said connections are located on both sides of the unit, so that the pipes can be connected on either side of the equipment.

Each unit is pressure and vaccum tested, then charged with the refrigerant required for proper operation based on the client installation conditions.

Our units can handle different communication protocols; such as Modbus and Bacnet, the most commonly used protocols in the HVAC industry.

The individual assembly of the units reduces installation costs on site, the units have a rigid base which bears the weight of the unit and allows an easy installation.

The units are then evaluated at full load operation with water flow, thermal load and line voltage set to the actual conditions in which the equipment will operate. Finally the units are performance tested at application temperatures ranging from -10 °C to 45+ °C.

• Maintenance

NOTE: The warranty policy requires that the start up be made by qualified and authorized personnel.

Our units keep track of all the programming variables in real time, as well as monitoring performance and specific alarms in the refrigeration cycle, the electrical system as well as external factors such as fire and flood detection (optional sensors). The control and monitoring system ensures the proper operation of the unit by monitoring in real time the health of all mayor components (high and low refrigerant pressure, compressors and fan motors health, etc). In case of a malfunction the event will be recorded for later analysis, facilitating the location of the possible failure and its solution.

The simplicity in the design of each unit allows maximum ease in maintenance. All mayor components are available to maintenance personnel by opening the service panel. If an emergency stop occurs, the control section will indicate the detailed cause of the failure, helping to accelerate and facilitate the solution process.

Units are built with control and design in mind, assembled with technically specialized control software. Some of our features are in house production of all piping and wiring, scroll type compressors, new generation evaporators, air cooled condensers, optional hydraulic components, and several safety and security protections.

(Fig. 1)

• COMPRESSOR

Set the switch to the ON position (Figure 2), this will allow the compressor to turn ON and OFF according to the status.

COMPRESOR

NOTE: Once the pump is turned on it starts a delay of a few seconds until a uniform water flow is detected, at the end of this delay, the flow switch is monitored, if the switch is open it commands the pump to shutdown (5 tries within a space of 10 seconds), if a uniform water flow is detected the unit starts its operation. Under normal conditions, the equipment will operate turning on and off the cooling circuit of the unit, according to the cooling demand. When alarms are presented in the system it will always be indicated on the user interface. The digital control will begin the operation of the compressors according to the logic set on the control.

The sequence of operation begins with a review of all points of pre programmed computer control security, if the necessary conditions are met the unit is ready to start its operation. To start the operation of the equipment set the ON / OFF switch to "ON" (Fig. 3) position. After a few seconds the computer will command the power of the water pump. If the computer detects water flow it will command the start of the internal control sequence of this unit.

PUMP STARTUP The pumps in the units are always working independent of the thermal demand; flow detection as well is always being monitored. If after the timeout flow detection, digital input status change is detected, the unit start is enabled by demand for the unit in question. Fig. 5 shows an example of this case. If the flow detection fails after the elapsed time for digital input detection, it is necessary to turn off the pump and back on to make an attempt to start after the waiting time between attempts has elapsed. If after a certain number of attempts flow is still undetected, the flow alarm is triggered and the operation of the unit in question is disabled, as illustrated by Fig. 6.

REGULATION The temperature control can be performed in different ways depending on the system configuration. If there are “Son” units present, the temperature can be set in "Tandem" mode (all the units are coordinated by the Mother unit from the calculation of aggregate demand) or each unit can work in "standalone mode", where each unit calculates the local demand from its respective injection temperature sensor (in case of failure of the injection head sensor). In "Tandem" mode, the control temperature is the reading from the main head sensor. From this reading the global demand is calculated. Fig. 7 shows an example of calculating demand when the control is set to "Proportional". If the units are in "independent mode", each unit calculates its local demand from its injection temperature sensor. Local demand for the Mother unit is generated by the same PID control equations, while the demand for “Son” units is a starting and stopping cycle with hysteresis, as Fig. 8 shows. The choice between heating and cooling (when the system was configured as a heat pump) can be performed by the digital input terminal. All units in a tandem always work in the same mode.

UNIT ROTATION When the system is operating in tandem mode, global demand is calculated as mentioned in the previous section, depending on how many units are operating, the system will request the start or stop of units to meet demand. In any configuration, the mother compressor (whose capacity is controlled by a variator or flow valve) is the first to start and the last to stop. Fig. 9 shows an example of the management of the global demand starting and stopping units.

When because of demand the startup or shutdown of the units is requested, and the system is working in tandem mode, the system can perform the rotation of units for better wear balance between the units. The types of rotation that may be performed include: • FIFO. The first unit to start is the first unit to stop. • LIFO. The first unit to start is the last unit to stop. • Cumulative operation time. Always starts first the unit with fewer hours of accumulated work, and the first unit turned off is the one with the most cumulative hours. • Custom. You assign priorities to start and stop each unit. Note: Regardless of the type of unit rotation set, the unit with frequency variator or discharger remains the first to start and the last to stop. Note: If a unit is working and stops for any situation (like an alarm), it will be replaced by the next available unit in the rotation algorithm.

• DEFROST ROUTINE

Fig. 9 Example of managed delivered capacity according to demand, for a mother unit and two Son units of 10T cooling each.

CONTROL

Only air-cooled machines that function as a heat pump can program a defrost routine in the condensing unit. This icing is done every so often and can be done in two ways: by reversing the operating mode (heating / cooling) or stopping the compressor without stopping the fan. This deicing is performed simultaneously in all units enabled in the system. You can set the frequency, mode of work, its duration, and the duration of the drip. This defrost routine can be disabled by the user.

Note*: the BMS1 port requires a communications card (pCOnet to BACnet MS/TP or pCOweb for BACnet IP). Programming of the logical package in the alternate protocol is also needed. Also can be connected a FLG- Modbus to connect a bacnet MS/TP.

ALARMS The alarms that may occur, depending on the initial configuration are: • Sensor Failures Alarms: If a sensor is detected as disconnected or broken, the algorithm which is used will be disabled. If the sensor is the head injection sensor, the units will work in standalone mode automatically • Phase Failure Alarm: activated by a digital input. The MotorSaver alarm is a high priority situation and stops all machine functions. It is manually reset. • No Flow Alarm: The No Flow Alarm is a high priority alarm and must be manually reset. This alarm stops all machine functions. • Freezing Alarm: If the freezing temperature sensor is below a programmed threshold, the freeze alarm is triggered. This condition stops all functions of the equipment in question. This alarm is automatically restored when the temperature exceeds a value of restitution and keeping the unit in reset mode (no power to operate) for the scheduled time. • Freezing Water Alarm: Same case as the freezing alarm, but in this alarm the reading from the injection sensor is considered. • High Pressure Alarm: It is activated through a digital input. This alarm is a high priority event and stops compressor operation; but it does not stop the pump. It is a manually reset alarm. If the unit is cooled by air a command is sent to start the fan of the condenser unit. To restore keep the unit in high return, the compressor will not start until the scheduled time has elapsed. • Low Pressure Alarm: It is activated through a digital input. This alarm stops the compressor of the unit in question. It is automatically restored but keeps the unit in a low return mode.

• Condenser High Temperature Alarm: This alarm is enabled only when the unit is air-cooled. The alarm is activated when the reading from the condenser temperature sensor exceeds its limit. No control action is taken. • Condensate Flow Alarm: the condensate flow alarm functions like the main flow alarm; the alarm routine is activated only when the system is cooled by water. • Lack of Refrigerant Alarm: this alarm is activated when a start command is sent because of cooling demand, and after a while no temperature change is detected in the injection temperature sensor. This alarm takes no action control and can be disabled by the user.

• Disconnection Alarm: If the system was setup with any “Son” units and any of these units disconnects this alarm will be trigged.

By pressing the "Alarm Present" button, the alarm screen shown below is displayed. In this screen all alarms that are active at that time are shown. Any alarm can be reset with the "Reset" button. It is worth mentioning that if the alarm condition is not corrected, the alarm will be triggered again.

ALARM LOG

Within the navigation bar of these two screens the button "Alarms Logâ&#x20AC;? will be displayed.

BY PRESSING THIS BUTTON, THE USER IS TAKEN TO THE SECTION "ALARM LOG".

GRAPHS

The pGD Touch terminal stores in its internal memory the temperature data readings of the injection and return sensor in the head unit, and injection and return temperatures for all units enabled. Pressing the Graphics button in the navigation bar of the home screen will take the user to a menu where graphic type can be selected. In the section "head unit" (and only if the sensors are enabled in the head unit) readings for the injection and return of the mother head unit are displayed. In the section "units" sensor readings for injection and return for all units are shown. The graphics properties that can be edited are: Duration (time scale) and minimum and maximum limits (temperature scale). These properties are edited in the navigation menu screens where graphics are displayed by pressing the "graphics settings" button. The pGD Touch terminal stores a reading for each of the temperatures mentioned (head injection and return, and injection temperature for every unit enabled) every 180 seconds (every 3 min) and may save up to 100,000 data samples before rewriting the oldest data. With these parameters, the pGDTouch can store data up to seven months old (208 days old).

CONTROL

In this screen you can see the alarms that have been activated in a given period of time. These records are stored in the internal memory of the terminal so it does not matter if the alarm condition is no longer present, it will be saved in memory for review at a later time.

If a unit icon is pressed, the user will be sent to the summary page containing more detailed information of that unit. In this page you can view the system inputs (temperature sensors, digital inputs for suction and discharge pressure of MotorSaver) and outputs of the unit (compressor, pump and fan). In this case we can find two kind of displayÂ´s one with palette water flow sensor and another with ultrasonic water flow sensor, that depends of the kind of unit you have.

For a water heat pump chiller you will see the outlet condenser temperature and the condenser flow.

In the navigation bar of these pages is the icon of "Input / Output". This will display a screen with the explicit information of all inputs and outputs of the configured devices in the initial setup. This screen is also accessible via the navigation button with Level 1 "Maintenance".

CONTROL 53 V.1.1

REGULATION In the regulation section, the user can modify the set point for cooling and heating (for units configured as a heat pump) and choose the operation mode of the units.

â&#x20AC;˘ Central control (tandem): means that the control temperature sensor is the injection sensor in the head unit. This reading will be displayed in the initial screen and the calculation of global demand will decide on the operation of all units. Unit rotation logic is also enabled. â&#x20AC;˘ Independent control: ignores the injection and return temperature sensors in the head unit. In the screen the temperature readings for injection and

return of the Master unit will be displayed. Every unit will generate its own demand load based on its injection temperature. Unit rotation logic is disabled.

Note: If the system is configured as central control, but the sensors in the head are broken or disconnected, the system automatically switches to standalone mode.

54 V.1.1

WORK MODE SELECTION

This section is only enabled for systems that are configured as "heat pump".

The work mode selection screen is divided in two sections: â&#x20AC;˘ Selection work mode from the terminal or Digital input â&#x20AC;˘ Current work mode indicator.

The selection of the operating mode can be configured in two ways: by digital input or by selecting it in the terminal (configuration section). If the working mode selection is done via digital input any other selection at the terminal will be ignored. If the work mode selection is set by the user at the terminal, only via this screen can the work mode be edited or changed, ignoring the state of the digital input.

In the clock settings page the user can set and change the date, time and how to display the date: there are two options, standard format (day-month-year) or US format (Month-Day-Year).

SETTINGS In the Settings section, password-protected access level 2, the parameters for the control and management of demand for cooling (and heating for the systems configured as heat pump) are shown. The parameters for the central control (“Tandem Mode”) are completely independent of the type of regulation in standalone mode, with the exception of the cooling set point, the heating set point and the choice to erase the accumulated integral error when the set point is reached.

CENTRAL CONTROL OR TANDEM The control parameters in the central regulation mode or tandem using temperature control as the temperature of a head unit are: • Central control parameters or “Tandem Mode”: • Type of regulation (P, PI or PID) • Remove the integral error when reaching the set point to avoid fluctuations inherent to the integral control • Rotation Type • Differential (Chiller and heat pump) • Neutral zones (chiller and heat pump) • Derivative time Note: To set PD control, select PID and set the integral time to 0. Note: Even if you select the rotation type as custom, the unit with frequency variator or unloader (master unit) will always be the first to be turned on and the last to be turned off, regardless of their assigned priority.

• If the type of rotation is selected as Custom, a window will be enabled to prioritize the start and stop of the units enabled with the button marked • The order of priority is ascending, with 1 being the highest and 5 the lowest priority. • The available unit (without alarms) with higher priority is first turned on or stopped.

CONTROL

• Integral time

57 V.1.1

INDEPENDENT CONTROL Independent control computes all the parameters that regulate the demand control in each unit independently using the injection temperature as the main parameter.

As the master unit can regulate its capacity, it has a single proportional control algorithm, P + I, or PID with independent parameters to the central control. If you want to set the PD control, the user must select PID and set the integral time to 0 sec. • Parameters mode or central Independent regulation for Master unit: • Type of regulation (P, PI or PID) • Remove the integral error when the set point is reached to avoid fluctuations inherent to the integral control. • Differential (Chiller and heat pump) • Neutral zones (Chiller and heat pump) • Integral time

CALIBRATION

In the calibration section, protected by password level 2, the user can adjust the sensor readings connected to units so that they match the readings in a measurement pattern. In addition, you can set the operating logic of the digital inputs; they can be "normally open" (NO) or "normally closed" (NC).

CONTROL

Also you can calibrate the minimum flow to be permitted to start the system, the chiller system require 2.4 Gal/min per Ton. So if you have a 10 Ton chiller you will need 24 gal/min, in some cases if the hydronic installation can´t provide these flow you can rise to 80 % of you permited flow to reduce the flow alarms, be carful to decrease down to 80 %, could have several problems in your system

60 V.1.1

For water heat pump you will see the condenser sensor, don’t change the Max and Min. Value shoul be configured in the facility

This kind of sensor can´t messure up to 39.6 gal/min so if you have more of this value the value in tne display tag going to show 295.6 prox. Check your hydronic system to regulate the flow. The value consider acceptable will be the same for evaporator and condenser sensor.

EXPORT RECORDS

• The user may export to a USB drive all the data stored in the unit to a commaseparated value format (CSV) file. The user may export 3 different files with different information: • The alarm log • The injection temperature of the master unit and if available head unit temperatures • Injection temperature for “Son” units (if present in the system)

DELETE RECORDS In the last section of the level 2 navigation menu, the user may delete historical graphics and alarm records from the internal memory of the pGDTouch terminal. Note: If the records are deleted they cannot be recovered later.

CONTROL 61 V.1.1

CONFIGURATION

The global configuration of the system is protected by password access level 3. In the configuration section are the global parameters of the system. These are separated into three categories:

Global Parameters • Reset Delay: if the controller is turned off, when resetting the controller will wait this time before beginning regulatory processes. • Enable unit on by digital input • Selecting the operating mode • Set point Safety Limits

Network Communication

CONTROL

The controller port BMS2 may be used for monitoring the entire system remotely with an external supervisor via Modbus RTU protocol.

DEVICES This section contains device configuration parameters for each of the enabled units. On the first page of the section, the user can enable or disable units to prevent their operation (in case of maintenance for example). Disabled units are

ignored in the rotation algorithm and may not start by demand.

The minimum demand to start the master unit is also set here. If the unit is modulated by a downloader the period is also set here. You can also determine if the units are of different capacities (only if at least one “Son” is present).

On the second page of the Devices section, the user sets the parameters for the alarm routines. The screen contains four groups (or five if the units are airwater); the following are the alarm routines: • Water Flow Alarm • Ice Water / Freezing Alarm • Low Vacuum Pressure and High Discharge Alarm • Refrigerant Alarm Unit protection time lapse: • Charging time (time between starts of multiple units) • Discharge time (time between the stop of several units) • Minimum time for compressors cycles • Minimum time for pump stop • Start Delay and fan stop (Only for air-water equipment).

• Condensing Unit High Temperature Alarm (only for air-water equipment)

CONTROL

Unit Capacity: If the system is set up with units of different capacities, a button will be enabled that will open this window, here the user may set the enabled units individual capacity.

63 V.1.1

FLOW ALARM Detection routines for water flow are explained in the section "Starting Pumps." The parameters that the user must assign are:

• Waiting time for detection of the digital input once the pump has been turned on • Number of attempts to start the pump in case of digital inflow detection failure • Timeout between attempts to start the pump

FREEZING & COLD WATER ALARM The freezing and ice water logic are the same, except that a one considers the freezing sensor, and the other the injection sensor as the main source of data

CONTROL

For each of the alarms a trigger value, restoration time and recovery time (in which the active alarm unit will not restart) should be established. Each unit has an internal counter that keeps track of how many times the unit has had a freezing or cold water alarm. If the unit exceeds a certain number of alarms in a given time, the continuous freezing alarm will be triggered, which will disable the unit until the user reestablishes the unit.

64 V.1.1

HIGH & LOW PRESSURE ALARMS The High and low pressure alarms are activated immediately after a change has been detected in the digital input. Both alarms stop the compressor operation immediately. The high pressure alarm does not reset automatically, the user must restart it manually. The low pressure alarm is automatically restored when a change is detected in the corresponding digital input. During alarm reestablishment the compressor is disabled during the recovery time that the user sets in this section.

REFRIGERANT ALARM

The Refrigerant Alarm is a user-enabled warning that evaluates the change in the injection temperature sensor when the compressor starts working. If it detects a change in the given time the alarm is triggered. This alarm will not stop any routine control. In this section the user can enable or disable the alarm, and if applicable, set the minimum detection rate and the maximum time in which this change should happen to not trigger the alarm.

This routine is only enabled if the System is air cooled

This alarm is triggered when the condenser temperature sensor exceeds the value set in this section. This alarm is a warning, it does not affect any routine control or stop the compressor from operating.

RESTORE

In the last section of the password access level 3 is the option to restore the unit to factory settings.

Restoring the system allows the user to reconfigure the system as a brand new installation and re-establish the initial settings. The restoration resets the parameters of initial system configuration, but does not modify any other values stored in the controller memory (set points, differentials, alarms, etc.).

It is the responsibility of the user to properly configure the system with the new configuration for the correct operation of the units.

CONTROL

Note: When the system is restored, the user must restart both the controller (pCO) and the terminal (pGDTouch).

APPENDIX

â&#x20AC;˘ Expansion Modules Serial Address Each slave unit uses an expansion module that communicates via Modbus with the Master (PCO) controller via the port controller Fieldbus1. Consequently, the units need to be configured with the correct serial address. To avoid errors the serial address is set and fixed when the controller is programmed and cannot be changed. The only thing that the users have to do is set the physical direction of the expansion modules by combining four "dip switches" in each expansion module. The address in the "Switches" is set with the four-bit binary number that they represent. The switch down position is "1", and the up position is "0".

No other serial address will be recognized, the expansion module disconnect alarm is triggered if a wrong address is used.

92 V.1.1

• • • Figure 2 - Use forklift or crane to lift unit (s).

Make sure that there is a strong, solid foundation to reduce noise and vibrations. Avoid installing the unit in areas that could be dangerous during maintenance operations, such as platforms without handrails, guide rails or in areas that fail to comply with requirements as regards free space around the unit. The installer is responsible for calculating the best position for the unit. It is vital that all minimum distances for all units are complied with to ensure there is adequate ventilation for the condenser racks. When deciding where to position the unit and to ensure proper airflow, the following factors must be taken into consideration: Avoid the recirculation of hot air Avoid insufficient air supply for the air cooling condenser. Both these conditions can cause an increase in condenser pressure which can lead to poor energy efficiency and refrigerating capacity.

The noise generated by the unit is mainly due to the rotation of compressors. The noise level for each model size is listed in the documentation. If the unit is correctly installed, operated and maintained, noise emission levels do not require any special protective devices to operate continuously close to the unit without any risk. In case of installation with special noise requirements it may be necessary to install additional noise softening devices. When transporting the unit, it is recommendable to use a forklift or crane to lift it. All units have lifting points. Only these points may be used for lifting the unit, as shown in the following figure.

â&#x20AC;˘ LOCATION The unit must be inspected for any possible damage immediately upon reaching the final site of installation. All components described in the delivery note must be inspected and checked. Should there be evidence of damage, do not remove the damaged components and immediately report the extent and type of damage both to the transportation company and the manufacturer's representative, sending if possible photos which may be useful in identifying those responsible for the damage. Damage must not be repaired before the inspection of the transportation company representative and the manufacturer's representative. Before installing the unit, check that the model and power supply voltage shown on the nameplate are correct. The manufacturer will not accept responsibility for any damage following acceptance of the unit. Provide enough space around the outdoor unit to allow the installation and maintenance personnel unrestricted access to all service points. Refer to submittal drawings for the unit dimensions. A minimum of 1 meter is recommended for compressor service. Provide sufficient clearance for the opening of control panel doors. Refer to Figure 1 for minimum clearances. In all cases, local codes which require additional clearances will take precedence over these recommendations.

All wiring must comply with local codes and the National Electric Code. Typical field wiring diagrams are included at the end of the manual. Minimum circuit ampacities and other unit electrical data are on the unit nameplate. See the unit order specifications for actual electrical data. Specific electrical schematics and connection diagrams are shipped with the unit.

WARNING

Proper Field Wiring and Grounding Required! All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state electrical codes. Failure to follow code could result in death or serious injury.

PREPARING AND CHECKING THE WATER CIRCUIT CONNECTION The units have a water input and output for the connection of the chiller to water circuit of the system. This circuit must be connected to the unit by an authorized technician and must comply with all the current national and local regulations on the subject. The components listed below are not included with the unit, but are supplied upon request, also if their installation is compulsory. If dirt penetrates the water circuit, there could be problems. Therefore always remember the following when connecting the water circuit: 1. Only use pipes that are clean inside. 2. Keep the end of the pipe facing downward when removing any burrs. 3. Cover the end of the pipe when inserting it through a wall to avoid dust and dirt getting in 4. Clean the pipes of the system located between the filter and the unit, with running water, before connecting it to the system.

THE WATER PRESSURE MUST NOT EXCEED THE MAXIMUM OPERATING PRESSURE FOR THE UNIT. WARNING

• PROCEDURE OF VACUUM AND REFRIGERANT CHARGE

WARNING

Never disconnect the copper tube of valve 3; just loosen the connection to purge the nitrogen

In order to obtain a precise reading of vacuum one should isolate the vacuum pump from the system. Close valve 1 and wait about 15 to have a precise measure. If the reading doesn’t remain steady either the system still contains humidity or there must be a leakage. Always verify all the connections (points 1, 3 and valves). * High Vacuum Method It is applied with a vacuum pump capable to reach vacuum lower than 500 microns in only one evacuation. Proceed as follows: 1. Turn on the vacuum pump, then open valve 1 (fig 19). Later on, isolate the vacuum pump and open the valve. 2. When a reading lower than 500 microns is obtained (try to reach the lowest possible value), the vacuum procedure will have been completed.

REFRIGERANT CHARGE After evacuating the system appropriately, close the valves of the manifold and isolate the vacuum pump, the vacuum gauge and the Nitrogen cylinder. To do the refrigerant charge, replace the Nitrogen cylinder shown in Fig. 18 with a refrigerant cylinder. Purge the hose that links the cylinder to the service valve. Open the service valve which gives access to the refrigerant cylinder and then the high-pressure valve of the manifold. To load the system appropriately, verify in the identification labels of the units the amount of refrigerant that should be added to the system. With the system shut down, load the refrigerant in liquid form through the service valve of liquid line (smaller diameter). For help, use a scale (if not using a graduate cylinder). Allow at least 10 minutes before turning the unit back on. Close the discharge valve of the manifold, open the suction valve and with the system in operation complete the charge with refrigerant in gas form (between 5% and 20% the total). Check in the scale the refrigerant weight added to the system. When the charge is complete close the suction valve of the manifold, disconnect the suction and discharge hoses.Close the cylinder valve. The charge procedure will be complete. REFRIGERANT WITHDRAWAL If for any reason there is need to remove/lose refrigerant, the service valves of these units allow to remove refrigerant from the system into the outdoor unit. Procedure: Step 1: Connect manifold hoses to the vents of the outdoor unit service valves. Step 2: Close the service valve of 1/4” liquid line. Step 3: Turn on the unit in cooling mode until that the system pressure reaches 2 psig. Then, close the service valve of the suction line 3/8 “ so that the refrigerant gas remains withdrawn.

The refrigerant must be adjusted a 20% in order to reach the evaporation temperature. You can check the charge in the next page. NOTE

INSTALLATION

Every system that has been exposed to the atmosphere should be properly dehydrated. That is possible if we accomplish appropriate evacuation. To make a proper evacuation, it is necessary to have a VACUUM PUMP (not compressor) and a vacuum gauge. The procedure is the following: • First the access points to the system must be defined. Use the service valves in the outdoor unit on both the drop and the discharge sides (liquid line). That is, high-pressure valve connected to the piping of smaller diameter and the low-pressure valve connected in the piping of larger diameter. • Only then is it possible to evacuate the system. Basically, we can do in two ways: * Method of Dilution Turn on the vacuum pump and make the vacuum in the pump (valve 1 shut). Open valve 1 and let the system evacuate until it reaches at least 500 microns. To obtain the measure, close valve 1 and open valve number 2, allowing the vacuum gauge to feel the system pressure. After reaching 500 microns, isolate the vacuum pump and open valve 3, letting the Nitrogen in to break the vacuum. Isolate the Nitrogen cylinder. Purge the Nitrogen through the connection that links the copper passage to valve 3. Repeat the procedure at least twice, doing in the last stage the third evacuation. At the end of this process, at least 200 microns should be obtained.

WARNING

The pump oil should be replaced periodically in order to guarantee the vacuum efficiency.

MAINTENANCE Servicing or maintenance of these unit must be carried out by experienced personnel with specific training in refrigeration. Repeated check the safety devices and continuous cycling of control components must be analyzed and corrected before being reset. The simple design of the refrigeration circuit totally eliminates potential problems during normal unit operation. No maintenance work is needed on the refrigeration circuit as long as the unit is operating normally. Ease of maintenance has been taken into consideration during the design stage such that the unit is easily accessible for servicing and maintenance. By accessing from the front panel of the unit, servicing and maintenance operation can be done easily. The electrical components are especially easy to access since it is located in the terminal box on top of the front panel. Under normal circumstances, this chiller requires only a check and cleaning of air intake through the coil surface only. These can be done monthly or quarterly depending on the surrounding enviroment where the units are installed.

MAINTENANCE

When the surrounding enviroment is very oily or dusty, then the coils must be regularly cleaned by a qualified air conditioner service technician to ensure sufficient cooling capacity and efficient unit operation. The normal life span might be shortened if no proper service is provided. For consistent performance and durability, always conduct proper and regular maintenance to the unit. For prolonged periods of operation time, the heat exchanger will become dirty impairing its effectiveness and reducing the performance of the units. Consult your local dealer about the cleaning of the heat exchanger. No major maintenance or servicing needed for the internal water circuit in the unit except the water pump failure. It is advised that regular check on the stainer to be conducted and change the water stainer if it is dirty or choked.

104 V.1.1

Always check the water level in the system, in order to protect the moving components in the hydraulic kit from over heating and excessive wear and tear.

The manufacturer will not be responsible for the malfunction of any unit if the main cause is the lack of maintenance or operating conditions which do not correspond to those recommended in this manual. NOTE

GENERAL

In the initial operation and periodically during startup, you must perform some routine maintenance checks. These include, verification of liquid lines, measurements of the condensing and suction pressure, and verify if the unit has normal overheating or undercooling. A maintenance program is recommended at the end of this section.

COMPRESSOR MAINTENANCE

The scroll type compressors are fully hermetic, and require no maintenance other than checking oil level.

ELECTRICAL TERMINALS

Electrical connections should be inspected and tightened as necessary. The heat and vibration can cause connections to loosen and fall off causing a voltage or arcing. • To service the electrical components:

• Tighten all cable connections connected to the terminal block and components. • Inspect connectors, cables and/or components with burn marks, worn cables, etc. If you find any connector, connection or component with any of the above conditions, it must be repaired or replaced. • The tension in the equipment should be checked with meter periodically to ensure adequate power supply.

NOTE

Each unit is shipped with a full wiring. See wiring diagrams when making connections. The electrical connections to be made in the place of installation are: power supply voltage line to the input power and control wiring for the remote control.

Do not place the control wiring with high voltage cable. High voltage can interfere with control signals and/or cause low or irregular performance.

MAINTENANCE

WARNING Risk of electric shock, can cause injury and death. Disconnect all electrical power sources when working inside the unit. Potentially lethal voltages exist within this equipment during operation. Observe all cautions and warnings in this manual. Only qualified personnel should maintain this equipment.

CONDENSER

Maintenance consists primarily of routine removal of dirt and debris from the outer surface of the fins and repair or damage fins.

MAINTENANCE

Clean fins with a vacuum cleaner, cold water, compressed air or a soft (non-metallic) brush. When it comes to units installed in a corrosive atmosphere, cleaning the fins should be part of the regular maintenance program.

106 V.1.1

In this type of installation dust and debris must be removed quickly to avoid accumulation that will hamper normal operation.

WARNING Risk of electric shock, can cause injury and death. Risk of serious injury. The fan can start up and cause injury. Disconnect all electrical sources before inspecting the fan.

FILTER-DRIERS Any residual particles from the condenser tubing, compressor and miscellaneous components are swept by the refrigerant into the liquid line and caught by the filter-drier. It is recommended to replace the filter drier whenever a repair is made in the cooling line.

EXPANSION VALVE

The expansion valve's function is to keep the evaporator supplied with the proper amount of refrigerant to satisfy the load conditions. Before adjusting superheat, check that the unit charge is correct and liquid line is full with no bubbles and that the circuit is operating under stable full load conditions. The suction superheat for the suction leaving the evaporator is set at the factory to 10 degrees F.

MAINTENANCE

WARNING Risk of explosive discharge of high pressure refrigerant. It can cause personal injury or damage to equipment. Never loosen any connections in the refrigerant lines or electrical lines until they are depressurized on both sides of the compressor.
