ROOM WALL MOUNTED AIR CONDITIONER
2. A white mist is coming out of the indoor unit.
• White mist may be caused due to a large temperature diff erence between air inlet and air outlet
on COOL mode in an indoor environment that has a high relative humidity.
• White mist may occur 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 fl owing or coming to a stop.
• You can also hear a sound «squeak» 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 fi rst turned on.
4. Dust is blown out of the indoor unit.
• This is normal when the air conditioner has not been used for a long time or during the fi rst use
of the unit.
5. A peculiar smell comes out of 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 from COOL or HEAT (for cooling and heating models
only) mode.
When indoor temperature reaches the temperatures 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 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.
8. Heating Mode (For Cooling/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 diff erence between indoor and outdoor temperature. If a comfortable temperature can't
be achieved by the air conditioner, we suggest you to use a supplementary heating devise.
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 fl ashing. 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. Lighting 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.
