TROUBESHOOTING TIPS
Cause
It is for the protection of the compressor, please
wait .
The crackling noises are caused by the contraction
and expansion of the front panel in response to
temperature differences.
The clicking noise may be heard caused by fan
or the compressor when switching on or off.
You may hear moving water. This is not a fault.
The refrigerant in the air conditioner may have
expanded.
The air conditioner also circulates the transpiration
from the walls, carpets, smoke, furniture and
clothing in the air.
Dripping water may generate on the surface of the
indoor unit when cooling in a high relatively humidity
(RH more than 80%). Adjust the horizontal louver to
the maximum air outlet position and select HIGH
fan speed.
The unit is designed not to blow cold air on HEAT
mode, when the indoor heat exchanger is in one of
the following three situations and the set tempera-
ture has not been reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
The indoor or outdoor fan stop running when
defrosting (Cooling and heating models only).
When room temperature reaches the temperature
setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to FAN
only mode. The compressor will start again when
the room temperature rises on COOL mode or
falls on HEAT mode (For cooling & heating models
only) to the set point.
