Trouble shooting
The following events may occur during normal
operation.
The unit will not restart for 3-4 minutes after it
stops
The unit is designed not to blow cold air on HEAT
mode.
This may occur when the indoor heat
exchanger is in one of the following three situations
and the set temperature has not been reached.
1.
When heating has just started.
2.
Defrosting.
3.
Low temperature heating.
The indoor or outdoor fan stop running when
defrosting
Frost may be generated on the outdoor unit during
heat cycle when the outdoor temperature is low and
humidity is high resulting in lower heating efficiency
of the Heat Pump.
During this time the Heat Pump will stop heating
operation and start defrosting automatically.
The time to defrost may vary from 4 to 10 minutes
according to the outdoor temperature and the
amount of frost built up on the outdoor unit.
A white mist coming out from the indoor unit
This may generate due to a large temperature
difference between air inlet and air outlet on COOL
mode in an indoor environment that has a high
relative humidity.
A white mist may generate due to moisture
generated from defrosting process when the Heat
Pump restarts in HEAT mode operation after
defrosting.
Low noise emitting from the Heat Pump
You may hear a low hissing sound when the
compressor is running or has just stopped running.
It is the sound of the refrigerant flowing or coming to
a stop.
You can also hear a low "squeak" sound when the
compressor is running or has just stopped running.
This is caused by heat expansion and cold
contraction of the plastic parts in the unit when the
temperature is changing.
A noise may be heard due to louver restoring to its
original position when power is turned on.
Dust is blown out from the indoor unit
This is a normal condition when the Heat Pump has
not been used for a long time or during first use of
the unit.
A peculiar smell comes out from the indoor unit
This may be caused by the indoor unit giving off
smells permeated from building material, from
furniture, or smoke.
The Heat Pump turns to FAN only mode from
COOL or HEAT mode
When
indoor
temperature
reaches
the
set
temperature the compressor will stop automatically,
and the Heat Pump turns to FAN only mode. The
compressor
will
start
again
when
the
indoor
temperature rises on COOL mode or falls on HEAT
mode.
The Heat Pump runs after turning off the unit
When turning off the unit under COOL (AUTO
COOL, FORCED COOL) and DRY mode, the Heat
Pump will run for 7-10 minutes, then stop the
operation and turn off the unit automatically.
Dripping water may condensate on the surface of
the indoor unit when cooling in a high relatively
humidity (relative humidity higher than 80%). Adjust
the horizontal louver to the maximum air outlet
position and select HIGH fan speed.
Heating mode
The Heat Pump draws in heat from the outdoor unit
and releases it via the indoor unit during heating
operation. When the outdoor temperature falls, heat
drawn in by the Heat Pump decreases accordingly.
At the same time, heat loading of the Heat Pump
increases due to larger difference between indoor
and
outdoor
temperature.
If
a
comfortable
temperature can't be achieved by the Heat Pump,
we suggest you use a supplementary heating
device.
Auto-restart function
Power failure during operation will stop the unit
completely.
When
the
power
restores,
the
OPERATION
indicator on the indoor unit starts flashing.
To
restart the operation, push the ON/OFF button on
the remote controller, the unit restarts automatically
with all the previous settings preserved by the
memory function.
