Installation Instruction
RiggingMove the unit using a forklift or crane of suitable capacity. See Table 1 for unit shipping weights. Locate the unit near a large-capacity drain to allow system drainage during unit shutdown and repair. Rig the unit using canvas belt. Fasten the belt over the units base as show in Figure 1.
Installation Checklist1). Reception• Verify that unit nameplate data corresponds with ordering information.• Inspect unit for shipping damages and material shortages; report any damages or shortages found to the carrier.
2). Unit Location and Mounting• Inspect unit installation location for adequate ventilation.
• Provide drainage facilities for water accumulated from the base.
• Remove and discard any shipping materials (e.g. cartons, crate, etc.)
• Inspect to determine that service access clearances are adequate.
• Install the optional neoprene or spring isolators at each mounting location.
• Secure unit to mounting surface.
• Level the unit.
Mounting methods that will minimize sound and vibration problems are:• Mount the unit directly on an isolated concrete pad or on isolated concrete footings at each unit mounting point.
• Install the optional neoprene or spring isolators at each mounting location.
Refer to Figure 2 for unit and base dimensions and Figure 3 for recommended service clearance.
Water pipingEvaporator Piping • Thoroughly flush all water system piping before making the final piping connections to the unit.• Connect the evaporator piping.
• Vent the air from chilled water system at the highest point.
• Install pressure gauges, thermometers and valves on water inlet and outlet piping.
• Install water strainer in evaporator supply line.
• Install balancing valve and flow switch on water outlet piping.
Caution:• If using an acidic commercial flushing solution, construct a temporary bypass around the unit to prevent damage to the evaporator.
• To avoid possible equipment damage, do not use untreated or improperly treated water.
Figure 4 illustrates typical unit piping components. Components and layout will vary slightly depending upon the locations of the connections and water source.
Caution:• To prevent unit damage, do not reverse system piping connections to the unit; water entering the unit must enter at the designated "Water In" and leaving water must exit the unit through the designated "Water Out" connection.
• Provide vent valve at highest point in the piping to bleed air from the chilled water system.
• To prevent damage to the waterside components of unit , do not al low evaporator pressure to exceed 0.5MPa (i.e. maximum working pressure).
• Before the final connection, flush carefully of all the external piping system . We have no any warranty for the case that impurities are combined in the piping.

Pressurized Expansion Water TankThe system is used to adjust the pressure and quantity. Install a handle stop valve at each side of the system, which is convenient to maintenance. Installation Principle Figure shows the installation method in detail.
Principle description of the pressurized expansion water tank:
1. In order to avoid the pipe cracking due to the system overpressure resulting from the change of ambient temperature and also to avoid the steam hammer in the pipes, a pressure-type water tank shall be added in the pipeline system.
2. In order to avoid the excessively high or low pressure in the pipe, an automatic makeup water valve and an automatic drain valve are added in the pressurized water tank. When pressure is under 0.6bar, the makeup water valve works automatically to replenish water, while over 5bar, the drain valve works.
3. The makeup water and drain pressure can be varied with the jobsite situation.

Electrical data
Electrical wiring• Connect unit power supply wiring to appropriate terminals block on distribution box.• Connect control panel (installed indoor) wiring to main control board.• For no-pump option only, connect chilled water pump power supply wiring to the proper terminals of the chilled water pump.• Properly ground the unit, the chilled water pump motor, and other devices which require grounding.• If with electric heater option, connect the power supply and control wiring to its terminal Tb2, which is shown on page 13.• If the interlocked controlling of the two-way valve of fan coil unit is available, disconnect the jumper JP6 on the control panel on spot, and connect the interlocked points to control terminal 12 and U.• Connect flow switch to the corresponding terminal U( or L) and 15.
Caution: To prevent injury or death, disconnect electrical power supply before completing wiring connections to the unit.
Note: Use only copper conductors for terminal connections to avoid corrosion or over heating.
Table 2 provides minimum circuit ampacities, recommended fuse sizes, and motor electrical data.
Unit Power SupplyRefer to the unit wiring diagram pasted on the control box cover. The installer must provide a power supply of proper voltage and a fused disconnect switch to the unit.
Refer to wiring diagram from page 15 to 24 for reference of a typical unit installation.
For actual wiring diagram, refer to the one fixed to the inside of control panel cover.
Note: The variation of input power voltage should be limited at ±10%.
Caution: For the 380V unit adopts the scroll compressor, the phase reversing and loss protection controller is installed which should be checked with electricity connection before start-up.If the green light of phase sequence in the control box is on, it means the phase sequence is right. Red light being on means the optional phases of power wiring should be exchanged, and the yellow means lacking phase which need check with electricity disconnection.In any case that the phases are reversed or lacked, the unit will shut down its operation and start-up automatically.

Pre-start Procedures
Voltage utilization rangeElectrical power to the unit must meet stringent requirements for unit to operate properly. Total voltage supply and voltage imbalance between phases should be within the following tolerances.Measure each leg supply voltage at all line voltage disconnect switches.
Readings must fall within the voltage utilization range shown on the unit nameplate ( 10%). If voltage on any leg does not fall within the tolerance, notify the power company to correct this situation before operating the unit.
Inadequate voltage to the unit will cause control components to malfunction and shorten the life of electrical components and compressor motors.
Voltage imbalanceExcessive voltage imbalance between phases in all 3-phase system will cause motors to overheat and eventually fail. Maximum allowable imbalance is 2%.Voltage imbalance is defined as follows:
Voltage Imbalance% =WhereVa = (V1 + V2 +V3) / 3(Average Voltage)V1, V2, V3 = Line VoltagesVd = Maximum Line Voltage deviation from Va.
Water flow rateEstablish a balanced water flow through the unit. Flow rates should fall between the minimum and maximum values indicated in (TABLE 5). Evaporator water flow rates below the minimum acceptable values will result in a stratified flow; this reduces heat transfer and causes either loss of expansion valve control or repeated nuisance low pressure cutouts. Conversely, excessively high flow rate may cause erosion in the water system.
Unit Water Pressure DropMeasure the water pressure rise across the standard unit (with built-in pump). The Externally Available Head (E.A.H) should approximate those indicated by the E.A.H. curves, with the corresponding flow rates.For units (without built-in pump) with field installed pump outside the unit, water pressure drop across the unit should approximate those indicated by the Internal Pressure Loss (I.P.L.) curves, with the corresponding flow rates. For standard unit with built-in pump, refer to the E.A.H. curve for the system hydraulic design. For optional unit without a built-in pump, refer to the I.P.L. curves. (Refer to Figure 6 for hydraulic characteristics of all models.)
Pre-start Checklist• Inspect all wiring connections; electrical connections should be clean and tight.• Check power supply voltage to the unit. • Fill the chilled water circuit, leaving the system air vents open. Close vents after all air is out, and the system is completely filled.
• Remove jumper wire for water system testing.• Close the fused disconnect switch and s tar t the un i t by turn ing the ON/OFF switch to ON position. Pump should start and with water circulating through the chilled water system, inspect all piping connections for leaks and make any necessary repairs.• Adjust the water flow rate through the chilled water circuit, and check the external available water pressure of the unit (for standard unit) or the evaporator water pressure drop for the no-pump option unit.• Stop the chilled water pump.Open all fused disconnect switches.• Make electrical connection of flow switch to terminals in the control panel.
Note: With the water pump operating, throttle the water flow to approximately 50% of the full flow rate. Following the manufacturer's instructions, adjust the flow switch contacts to open at this point. Use an ohmmeter to verify opening and closure of the flow switch contacts.

Start-up Procedure• Close the fused disconnect switch and press MODE button to choose heat or refrigeration,then turn OFF/ON switch to ON.
• Once the unit has operated for at least 30 minutes and the system has stabilized, complete the following checklist to ensure proper unit operation.
1. Check unit water flow and pressure. These readings should be stable at proper levels.
2. Measure unit suction and discharge pressures. Normal operation should render suction pressure in the range of 50-85 psig (0.34~0.586MPa) and discharge pressure 200-310psig(1.38~2.07MPa).
3. Check compressor amp draw.
4. Check electrical power supply.
5. Check the liquid line sight glasses.
6. Measure system superheat.
Normal system superheat is 5oC to 8oCfor each circuit at ARI conditions (12.2oCentering water, 6.7oC leaving water, and 35oC ambient temperature). If the superheat measured for either circuit does not fallwithin this range, alter the setting of the superheat adjustment on the thermal expansion valve to obtain the desired reading. Allow 15 to 30 minutes between adjustments for the expansion valve to stabilize at each new setting.
7. Measure system subcooling.Normal subcooling for each circuit is 5oC to 10oC ARI conditions (12.2oCentering water, 6.7oC leaving water, and
35oC ambient temperature). If subcooling for either circuit is not in this range, check superheat for the circuit and adjust, if required. If superheat is normal but subcooling is not, contact a qualified service technician.
8. If operating pressure, sight glass, superheat and subcooling readings indicate refrigerant shortage, find andrepair leaks and, gas-charge refrigerant into each circuit. Refrigerant shortage indicated if operating pressures are low and subcooling is also low.
9. If operating pressures indicate an overcharge, slowly (to minimize oil loss) recover refrigerant at the liquid line service valve.
• Be sure that all remote sensing bulbs are properly installed in bulb well. Remote bulb capillary tubes must be secured (i.e. protected from vibration and abrasion) and undamaged.
• Inspect the unit. Remove any debris, tools and hardware. Secure all exterior panels, including the control and compressor access panels. Replace and tighten all retaining screws.
Note:• Bubbles in the liquid line may indicate either a low refrigerant charge, or excessive pressure drop in the liquid line. But bubbles are not necessarily a symptom of improper system operation.
• A clear sight glass does not necessarily mean that the system is sufficiently charged; be sure to consider system superheat, subcooling, and unit operating pressures and ambient temperatures.
• If suction and discharge pressures are low, but subcooling is normal, no refrigerant shortage exists.Adding refrigerant will result in overcharging.
Operation
34
Operation
Extended unit shut-downIf the system is taken out of operation for long periods of time for any reasons (e.g., seasonal shutdown), use this procedure to prepare the system for shutdown.
1. Check the refrigerant piping for leaks, fixing any exist.
2. Service the chilled water pump and any air handling equipment according to the manufacturer's recommendtions.
3. Open both electrical disconnect switches for the unit and chilled water pump.
Note: In winter, close all evaporator water supply valves and drain the evaporator by removing the drain plug and opening the vent on the entering water line just outside the unit. Re-install the drain plug. Since the evaporator does not drain completely, add ethylene glycol antifreeze to the remaining water through the vent or evaporator drain hole, to keep the water from freezing.
System Restart AfterExtended Shutdown1. Fill the chilled water circuit by opening the gate valves at the returning and supply water piping. Be sure to vent the system while filling it, and close the vents when system is full.
2. Remove compressor delay for testing water system.
3. Close the unit disconnect switch for power supply.
4. Turn the OFF/ON switch to ON position. With water circulating through the chilled water system, inspect all piping connections for leaks and make any necessary repairs.
5. Adjust the water flow rate, using the balancing valve, through the chilled water circuit, and check the water pressure rise (or drop) through the unit.
6. Adjust the flow switch (installed on the unit outlet piping) to provide proper operation.
7. Stop the unit by turning the OFF/ON switch to OFF position.
8. Replace compressor delay back to original sockets. This unit now is ready for normal operation.
Note:With the unit operating, throttle the water flow to approximately 50% of the full flow rate. Following the manufacturer's instructions, adjust the flow switch contacts to open at this point. Use an ohmmeter to check for contact opening and closure.
System Protections
Low Pressure Cutouts (LP1, LP2)These units are protected by low pressure cutouts that open and stop compressor operation if the operating pressure drops below 8 4 psig(0.055 0.0276MPa).The cutout automatically resets when the pressure reaches 25 7 psig(0.172 0.048MPa).There will be a 2 minute override to prevent nuisance trip-outs.
High Pressure Cutouts (HP1, HP2)These units have high pressure cutouts that open and stop compressor operation if the discharge pressure reaches 400 10psig(2.76 0.069MPa).The cutout automatically resets when pressure drops to 250 15psig(1.72 0.103MPa).
System Anti-freeze ProtectionIN winter when unit is on standby and water temperature is below setting anti-freeze temperature, unit will automatically start and show "AP". So in freezing winter days, unit should be made stand by.
Anti-freeze Protection of Plate-type Heat ExchangeOn cooling mode, when leaving water temperature is below 3oC,compressorwill be shut up, pump remains on and show E3.
High Pressure Protection of Plate-typeHeat ExchangeDuring cooling model of single refrigerant unit, when refrigerant pressure is above a setting value, fan or fan and compressor will be shut up and show E3.
Motor Overloads• Compressor motor over load protection, overheating protection.• Pump motor overload protection.• Fan motor overload protection.• Temperature detectors protection. When Temperature detectors break down, system will alarm and unit will shut up.
Note:All alarm cutouts should be reset manually.After obstacle avoidance, press the RESET button or restart the unit to recover the system.
Water FlowIn order to avoid low water flow, which leads to freezing on evaporator, a water flow switch (or other water flow detector) should be installed on evaporator piping. A flow value should be set in order to stop compressor operation when waterflow rate is less than 70% of full flow rate.
Unit Operation
Temperature Detector (Th1)Temperature Detector senses the entering water temperature to determine start or stop of compressor on cooling and heating mode.
Cooling Mode
For Double Refrigeration Circuit OperationAt Start-up, the pump will come on immediately. Two minutes after the pump is on and EWT(entering water temperature) is above 13oC, compressor#1 will start. One minute later, if the EWT is above 15oC, compressor#2 will start.When cooling demand is met and EWTdrops to 11oC, compressor #1 will stop, i f EWT cont inues to fa l l to 10 oC,compressor #2 will stop. Subsequently,when load builds up and EWT rises to 13oC, compressor #2 comes on, and if EWT rises further to 15oC, compressor #1 comes on. Pump remains on unless the unit is turned off.
For Single Refrigeration Circuit OperationAt Start-up, the pump will come on immediately. Two minutes after the pump
is on and EWT(entering water temperature) is above 15oC, compressor will start.When cooling demand is met and EWTdrops to 10oC, compressor will stop. Subsequently, when load builds up and EWT rises to 15oC, compressor comes on. Pump remains on unless the unit is turned off.
Heating Mode
For Double Refrigeration Circuit OperationAt start-up, pump will come on immediately.Two minutes after the pump is on and EWT (entering water temperature) is below 37oC, compressor#1 will start. One minute later, if EWT is below 39oC,compressor #2 will start.
When heating demand is met and EWTrises to 41oC, compressor#1 will stop, i f EWT continues to r ise to 42oC,compressor #2 will stop. Subsequently,when load builds up and EWT drops to 39oC, Compressor #2 comes on, and if EWT drops further to 37oC, compressor #1 comes on. Pump remains on unless the unit is turned off.
For Single Refrigeration Circuit OperationFor units with only one refrigerant circuit, the operation of water pump, fan and compressor is exactly the same. Theonly difference is the unit will operate the single compressor from any temperature below 37oC and 42oC when the compressor will stop.
