Electric  air conditioner (split system)

EN

2. A white mist coming out from the indoor unit

A white mist may generate due to a large temperature diference 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 ater 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. It is the sound of the refrigerant lowing 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.

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 

irst use of the unit.

5. A peculiar smell comes out from the indoor unit.

This is caused by the indoor unit giving of smells permeated from building material, from furni

-

ture, or smoke.

6. The air conditioner turns to FAN only 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 FAN only mode. The compressor will start 

again when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and 

heating models only) to the set point.

7.The air conditioner runs Anti-mildew function ater turning of the unit.

When turning of the unit under COOL(AUTO COOL, FORCED COOL) and DRY mode, the air 

conditioner will run Anti-mildew function for about 10 minutes, then stop the operation and turn 

of the unit automatically.

8. Dripping water 

may generate on the surface of the indoor unit when cooling in a high rela-

tively humidity (relative humidity higher than 80%). Adjust the horizontal louver to the maximum 

air outlet position and select HIGH fan speed.

9. 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 

decreases accordingly. At the same time, heat loading of the air conditioner increases due to 

larger diference 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 

10. 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 indica-

tor on the indoor unit starts lashing. 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.

• 

For some models, the machine is special designed with Auto-restart function for the open 

angle of the horizontal louver.Power failure during operation or pressing the ON/OFF 
button on the remote controller will stop the unit completely.When the power restores or 
pressing the ON/OFF button on the remote controller again,the unit restarts automatically 
with all the previous settings including the open angle of the horizontal louver by the mem

-

ory function. So we strongly suggest that the open angle of the horizontal louver should not
