Trouble-shooting
Failures Possible reasons Solutions
Fan, pump and
compressor can not
start up
1. NO power
2. Power switch jumps
3. Power fuse is burnt.
4. Pump overloads. 1. Wait for power recovery
2. Check the power and make it normal
3. Change power fuse
4. Check and reset or repair the failure.
Pump runs but
compressor can not
start.
1. The setup value for temperature switch is too
high.
2. Failure in temperature switch.
3. Compressor overloads.
4. The setup temperature for compressor is too
low (for heat flow)
5. No restore after the protective switch jumps.
1. Edit the value.
2. Check or change.
3. Check and reset.
4. Edit the value (for heat flow)
5. Check and reset.
Compressor
stops
immediately
after it starts.
1. Air inlet or outlet gets hindered.
2. Condenser is dirty.
3. Bad ventilation due to bad landform.
4. Fan fails.
5. The cooling water valve has not been opened.
6. Overlow cooling water quantity.
7. Cooling medium leaks.
8. Compressor overloads. 1. Remove the hindering articles.
2. Wash and clean.
3. Improve by client.
4. Check and repair.
5. Open the valve.
6. Check the pump to remove the tube air.
7. Repair the leak spot.
8. Edit setup value.
Big lnlet/outlet water
temperature
difference and over
low low-pressure
(when cooling flow
runs).
1. Pipeline blocks due to wrong pipeline
switching
2. Too much gas in the pipeline.
1. Check the valve of the pipeline and
attachments.
2. Exhaust the air in the pipeline.
