User Manual Thermal X - R Series Chillers Page 27
If the leaking part is within water, stop the chiller immediately and discharge the water in the water
tank quickly. The compressor can be damaged badly if it sucks in water.
Low and High Pressure Difference
While the compressor is running, if the difference between high pressure and low pressure is small,
it may indicate the piston inside the compressor is damaged. If this is detected, the unit should be
stopped immediately. It is normal for the pressures to be similar if the compressor is not running.
Compressor Not Starting
If the fault indicator and the protection switch are normal, but the compressor will not start, please
check the following:
1. The set temperature is too high or the temperature sensor is damaged
2. The PCB button is damaged
3. The anti-freezing switch is damaged
4. The pressure switch is damaged
5. The overload protector of the compressor is damaged
6. The electromagnetic relay is damaged or the overload protector is damaged
7. The water level is too low
8. The refrigerating water protecting switch is damaged
MAINTENANCE
Warning:
- Always isolate the power from the chiller prior to working on the unit.
- Always ensure that personnel have read and understood the SAFETY section of this manual

components are not operating. All maintenance must be carried out by qualified refrigeration
mechanics.
