Failure Description
The appliance does
not work.
The appliance has
low heating capacity.
The compressor
does not work.
The compressor
works noisily.
The fan does
not work.
The appliance does not
produce heat, while
the compressor is
working.
Discharge pressure is
too high.
Suction pressure is
too low.
1) There is water flow out of the drainage outlet of the safety valve:
When producing hot water, the cold water within the appliance is heated and expands,
so there is water flow out of the drainage outlet of the drain valve, which is normal case.
However, if there is water extruding continuously, that means the safety valve loses efficacy.
Non-Unit
You should stop using the appliance and replace the safety valve as soon as possible.
Failure
2) The duration for heating a whole tank's water becomes longer:
When the temperature is quite low in winter (e.g. 0℃), the heat pump's performance
of producing hot water will not be as good as usual, so the duration for heating a whole
tank's water becomes longer.
ATTENTION
If the appliance remains abnormal after you check as above, please contact the local service center
or dealer to send servicemen to repair the appliance promptly. Try to avoid the fuse fusing orthe
leakage protector turning on and off back and forth.
