IV. Installation instructions

1. Lay the chiller machine in an indoor air position, and there should be some room around in order to operate and repair.

2. According to the chiller machine installation diagram, connect the waterpipe. Chilled water and cooling water ought to be separated. The water system pipeline should avoid changing direction to avoid lower the water pressure. Chilled water pipe should be kept cold. Make sure that the whole water pipeline is connected correctly, then operate the machine.

3. The connection pipe diameter reserved by set is the standard pipe diameter. When there is a long-distance transmission, we suggest using the same standard or one level lower pipe to connect. If the diameter of pipe is smaller than the standard diameter, please ask the manufacturer whether could be used, otherwise, the water pump and the compressor might be damaged.

4. This machine is three-phase five-wire or one-phase three-wire. Choose national standard line in accordance with current as the specifications of the power line please.

5. This machine is strict tested. Users can use it as long as you connect the water pipe and power line in accordance with circuit diagram.

V. Machine maintenance

1. When the unit is running, please pay attention to the pressure gauge. The high pressure should be lower than 20kgf/cm2, while low pressure should be higher than 2.0kgf/cm2. If the number is too higher or lower, it demonstrates that there would be a fault or you are not using it correctly.

2. Condenser and evaporator of chiller unit should be cleaned after using period of time.

3. If you stop using chiller unit for a period of time, the leaf of water pump might be solidified by crud. When starting up the machine again, you must use a screwdriver to stir the motor back cover wind leaf to avoid pump leaf getting stuck to burn the motor.

4. All the electronic components and protection equipment of unit have been strict tested. Do not change or demolish when checking and repairing. The forced running in the absence of protection will damage the unit.

5. The best temperature of chiller machine is 7℃-12℃, 5℃-35℃ is okay. If the starting up temperature is higher than 35℃ may lead to high pressure protection, compressor overloading, relay tripping and even soluble plug dissolving and blowing up.

6. Chiller machine belongs to high professional machine, so it should be used and maintained by professionals. Non-professionals do not operate or repair the machine to avoid danger.

VII Fault List

Fault	Description	Test Conditions	Troubleshooting	Solution
Comp.P high	High pressure of compressor	Test when the compressor button has pressed	Stop compressor only without affect other equipments to work.	Check if the input is consistent with the switch setting.
Comp.P low	Low pressure of compressor	If the [LP check delay] is 0, test when the compressor button has pressed; If the [LP check delay] is not 0, then compressor runs the test.		Check if the input is consistent with the switch setting.
Comp overload	The compressor overload	Compressor runs the test.		Check if the input is consistent with the switch setting.
Comp.I high	The current of compressor is too high			Check if the rated current of compressor1 is input is reasonable.
Comp.I low	The current of compressor is too low			Check if the measure tool of the compressor1 current is connect.
Temp.low AL	The liquid temperature is too low	Test after cold pump starts	Stop the compressor and delay to stop the cool pump, and do not stop the cold pump.	Check if the Liquid temperature is lower than the set temperature of Liquid protection.
T.high warn	The liquid temperature is higher than the warn value.	If 【HT detect dly】is 0,detect when the cold pump starts; if 【HT detect dly】is not 0,detect when the cold pump has run for set time.	Alarm only without affect other equipments to work.	Check if the Liquid temperature is higher than the set temperature of Liquid warn.
Temp.high AL	The liquid temperature is too high		If the [Temp.high AL] is set “Pump keep”,Stop the compressor and delay to stop the cool pump, and do not stop the cold pump; If the [Temp.high AL] is set “Pump stop”, Stop the unit in case of fault.	Check if the Liquid temperature is higher than the set temperature of Liquid protection.
Anti-freez.AL	Antifreeze alarm	Power on to test	Stop all the compressor and cool pump, and do not stop the cold pump.	Check if the antifreeze input is consistent with the switch setting.
Probe break	The liquid temperature sensor is break			Check if the temperature probe is in proper contact.
Probe short	The liquid temperature sensor is short			Check if the temperature probe is in proper contact.
Cool overload	The cool pump or fan overload	Test after Cool pump starts	Stop compressor and cool pump or fan only	Check if the fan1 overload input is consistent with the switch setting.
Cool.I high	The current of cool pump or Fan is too high			Check if the rated current of cool is input is reasonable.
Cool.I low	The current of cool pump or Fan is too low			Check if the measure tool of the cool current is connect.
Cool W.flow AL	Lack of cool water flow	Test after the cool pump starts for [Cool on delay] time.	Stop compressor and cool pump or fan only.	Check if the cool water flow input is consistent with the switch setting.
Cold W.flow AL	Lack of cold water flow	Test after the cold pump starts for [Pump on delay] time	If the [Lack of liquid] is set “Pump keep”, Stop compressor and cool pump in case of fault. If the [Lack of liquid] is set “Pump stop”, Stop the unit in case of fault.	Check if the cold water flow input is consistent with the switch setting.
Pump overload	The cold pump overload	Test after cold pump starts	Stop the unit	Check if the cold pump overload input is consistent with the switch setting.
Pump.I high	The current of cold pump is too high			Check if the rated current of cold is input is reasonable.
Pump.I low	The current of cold pump is too low			Check if the measure tool of the cold current is connect.
Phase AL	The three-phase power input is alarm	Power on to test	Stop the unit	Check if there is default phase or anti-phase in the three-phase power input and if the switch is correct.
Water level AL	The water level is low	Power on to test	If the [Low liquid lv] is set “Pump keep”, Stop compressor and cool pump in case of fault. If the [Low liquid lv] is set “Pump stop”, Stop the unit in case of fault.	Check if the water level input is consistent with the switch setting.
Need Maintain	The total time of compressor run over the allow value	Test after cold pump starts	The unit cannot start once stops (the accumulative operation time of compressor exceeds the set value).
