automatically.

• The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the

amount of frost buildup on the outdoor unit.

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 conditi-

oner 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 run-

ning. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the

temperature is changing.

• A sound 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 only mode from COOL or HEAT mode.

• When indoor 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 indoor temperature rises on COOL mode or falls on HEAT mode 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 out-

let position and select HIGH fan speed.

8. Heating mode

• 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 decre-

ases accordingly. At the same time, heat loading of the air conditioner increases due to larger diffe-

rence between indoor and outdoor temperature. If a comfortable temperature cannot be achieved

by the air conditioner, it is advised to use a supplementary heating device.

9. Auto-restart function.

• Power failure during operation will stop the unit completely.

The air conditioner is equipped with Auto-restart feature, when the power restores, the unit restarts

automatically with all the previous settings preserved by the memory function.
