The following checks prior to contact may save you time and money.
Malfunctions Cause
Water leakage
of indoor unit
• The humidity is high.
• Condensing water overflows.
• Drain hose is loose or
obstructed.
Water leakage
of outdoor unit
• During cooling operation, water
condensates around the pipes
and connection joints.
• During defrosting operation,
thawed water flows out.
• During heating operation, water
on the heat exchanger drips out.
Noise from
indoor unit
• The noise emmited when the fan
or compressor relay is switched
on or off.
• When the defrosting operation
is started or stopped, there is a
sound of refrigerant flowing in
the reverse direction.
Indoor unit can
not blow air
• In HEAT mode, when the
temperature of indoor heat
exchanger is very low, airflow 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
outlet
If the unit operates at high
humidity for a long time, moisture
may be generated on air outlet
grill and then drip off.
H1 error code:
defrosting
It is normal. The unit is in
defrosting operation and heating
will recommence soon.
Malfunctions Cause
The unit does
not operate
The unit does not operate if it is
turned on immediately after it is
turned off. This is to protect the
unit. Please wait about 3 minutes.
Odours are
emitted
• Some odours may be emmited
from the indoor unit. This is the
result of room smells (such as
furniture, tobacco, etc.) which
have been taken into the unit.
• Consult authorised service
center for cleaning if the odours
persist.
“Water flowing”
noise
The swishing noise like water
flowing is the refrigerant flowing
inside the unit.
Mist is
emmited in
COOL mode
During cooling operation, a thin
mist may be seen emmited from
the indoor unit due to high room
temperature and humidity.
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
temperature.
The unit can
not be started
up
• Is the power cut off?
• Is the power plug loose?
(if applicable)
• Is the circuit protection device
tripped off?
• Is voltage higher or lower?
(tested by professionals)
• Is the TIMER correctly used?
• Are the batteries exhausted?
Cooling
/Heating effect
is poor
• Is the temperature setting
appropriate?
• Is the air inlet/outlet blocked?
• Is the filter dirty?
• Is the door or window open?
• Is low fan speed set?
• Are there heat sources in the
room?
Do not dispose this product as unsorted municipal waste.
Collection of such waste separately for special treatment
is necessary.
