Phenomenon
Indoor unit can not blow air:
Moisture on air outlet :
C5: Malfunction of connector jumper:

sensor
H1: Defrosting
If any one of the following situations occurs, immediately stop all operations
cut off the power supply, and contact the authorized personnel
There is harsh sound during operation.
Strong odours are emitted during operation.
Water is leaking from the unit.
The air switch or protection switch often trips.
Water or other liquid is splashed into the unit.
Power cord and power plug is overheating.
Troubleshooting
In HEAT mode, when the temperature of indoor
●
heat exchanger is very low, air flow is stopped
in order to prevent cold air. (Within 2minutes)
In HEAT mode, when the outdoor temperature
●
is low or humidity is high, frost will be formed on
the outdoor heat exchanger. The unit will defrost
automatically and indoor unit will stop blowing
air for 3-12minutes.
During defrosting operation, water or vapour may
●
be emitted.
In DRY mode, the indoor fan will stop blowing air
●
for 3-12 minutes in order to avoid condensate
being vaporised again.
If the unit operates at high humidity for a
●
long time, moisture will be generated on
the air outlet grill and then drip off.
Check if the connector jumper contacts
●
properly. If the PCB is to be replaced,
please take off the old for the new PCB.
●
Check if indoor room temperature sensor is
connected properly
Check if the evaporator temperature is
●
connected properly.
It is normal.
