Before starting up the chiller have the following installation requirements been carried out
1.
The power supply voltage and phase should be in accordance with the specifications listed on
the chiller’s marking place.
2.
Check the ventilation of the unit.
3.
Check the refrigerant leak through pressure gauge before filling the unit with water
4.
Check the bypass in the tank. Make sure it’s closed to ensure the water flow to application.
5.
Check the power supply according to the requirements
Operating Sequence
1.
Open the valve of the supply pipe and return pipe and ensure the waterway is unimpeded.
2.
Turn the unit on with the master power switch.
3.
Press the run button on the interface panel to start the controller.
4.
Press the compressor start button on the interface panel to start the compressor.
5.
Pressing the power button while the unit is running will power off the unit.
The unit is ready to be started up. Once power is provided to the chiller, open the clear plastic guard
over the ON/OFF switch and turn the unit on and the unit will start automatically. The pump will start
immediately.
The compressors have a start delay. Once the compressors have cut in, watch the display to ensure
that the water temperature in coming down. Set points and operational parameters are displayed on
the screen. Any faults are indicated on the face of the control panel.
It is a good idea after the unit has been running for 5 minutes check that the water temperature is
dropping and check there are no bubbles in the sight glass (if fitted) – if these two things are happening
then the unit is running properly. Give the system a final check to ensure that there are no water and
refrigerant leaks.
Operating Precautions
1.
Chilled water pump cannot be started without water in the water tank.
a.
All standard models are equipped with water level protection in the water tank (except
for closed water tanks). The default setting is when the water level is too low, the unit
will throw an alarm and the pump will keep operate. However, this function can be
changed in controller. Once the function is changed, pump will stop running if water
level gets too low. Please make sure the function setting fits the application
requirement.
(Manufacturer Parameters – Control Setting – Low water lv. & Lack of water)
2.
Switching the operating switches frequently should be avoided.
3.
When the chilled-water temperature reaches the set temperature, the compressor will stop.
4.
In order to prevent the evaporator freezing, do not set temperature below 5 °C (Except for
sub-zero models)
5.
When the unit is not in use for long periods of time, drain the tank
6.
To ensure the most efficient operation, please clean the condenser, evaporator, and the water
filter (if fitted) regularly.
