Malfunctions
Cause
Water leakage
of indoor unit
The humidity is high.
Condensing water

the reverse direction.
Indoor unit can
not blow air
In HEAT mode, when the
temperature of indoor heat
exchanger is very low,
is
stopped in order to prevent cold
air. (within 2 minutes)
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 several mintues.
During defrosting operation,
water or vapour may be
emmited.
In DEHUMIDIFY mode, the
indoor fan will stop blowing air
for 3-12 minutes in order to
avoid condensing water being
vaporised again.
Moisture on air

After a period of time, the mist
will disappear as the decrease of
room temperature and humidity.
Cracking noise
This is the sound of friction
caused by expansion and/or
contraction of panel or other
parts due to the change of
