Special functions
Improving the quality of indoor air is one of the purposes of an air conditioner. Thisair
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.

OPERATION TIPS
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
The compressor can't restart for 3 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 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 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 function for 7-10 minutes, then stop the operation and turn
off the unit automatically.

8. 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.
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.
