Operation Tips
2.
A white mist coming out from the indoor unit
A white mist 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 air conditioner
restarts in HEAT mode operation after defrosting.
3.
Low noise of the air conditioner
You may hear a low hissing sound when the compressor is running or has just stopped running. This
sound 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 temper-
ature is changing.
A noise may be heard due to louver restoring to its original position when power is first turned on.
4.
Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first use
of the unit.
5.
A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from furniture, or
smoke.
6.
The air conditioner turns to Fan Mode from COOL or HEAT (For cooling and heating models only)
Mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to Health mode. The compressor will start again when the
indoor temperature rises in COOL mode or falls in HEAT mode (For cooling and heating models only)
to the set point.
7. Dripping water may generate 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.
OPERATING INSTRUCTIONS
8.
Heating mode (For cooling and heating models only)
The air conditioner 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 air conditioner de-
creases accordingly. At the same time, heat loading of the air conditioner increases due to larger
difference between indoor and outdoor temperature. If a comfortable temperature can't be
achieved by the air conditioner, we suggest you use a supplementary heating device.
9.
Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, 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.
For the unit with Auto-restart feature, when the power restores, the unit restarts automatically
with all the previous settings preserved by the memory function.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again. Push the
ON/OFF button on the remote controller to restart operation.
