•During Self Clean operation, when press the SELF CLEAN button on the remote controller again will stop the
operation and turn off the unit automatically.
CLEAN AIR function (on some models)
Improving the quality of indoor air is one of the purposes of an air conditioner. This air conditioner is
equipped with ionizer or Plasma Dust Collector(Depending on specific configuration of the model). With
the anions generated by Ionizer, the air circulation of the air conditioner fills the room with refreshing,
natural and healthy air. The Plasma Dust Collector generates a high voltage ionization zone, through which
the air is converted to plasma. Inside the air most of the dust, smoke, and pollen particles are captured by
the electrostatic filter.
Anti-mildew function (optional)
When turns off the unit on COOL, DRY, AUTO (Cool) mode, the air conditioner will continue operating for
about 7-10 minutes (depending on models) at LOW fan speed. If turns off on HEAT mode, the unit will
continue operating for about 30 seconds at LOW fan speed. This will help to dry up the condensed water
inside the evaporator, and prevent the breeding of mildew. Under Anti-mildew operation, do not restart
the air conditioner until the unit is completely off.
NOTE: This manual does not include Remote Controller Operations, see the Remote Controller Manual packed

Normal function of the air conditioner
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
•The compressor can't restart for 3-4 minutes after it stops.
Anti-cold air (Cooling and heating models only)
•The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the
following three situations and the set temperature has not been reached.
A) When heating has just started.
B) Defrosting.
C) Low temperature heating.
•The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
•Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and
humidity is high resulting in lower heating efficiency of the air conditioner.
•During this condition air conditioner 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.
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. 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.
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
6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and heating models only)
•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 function after turning off the unit.
•When turning off the unit under COOL(AUTO COOL, FORCED COOL) and DRY mode, the air conditioner
will run Anti-mildew function for 7-10 minutes, if it turns off on HEAT mode, the unit will continue
operating for about 30 seconds at LOW fan speed, then stop the operation and turn off the unit
8. Condensation
•Condensation may develop 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.
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 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.
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 indicator on the
indoor unit starts flashing. To restart the operation, push the ON/OFF button on the remote controller.
