Operation Tips
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
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 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.
OPERATING INSTRUCTIONS
Note:
The starting angle of the horizontal louver should not be too small, otherwise the
narrow air outlet will affect cooling or heating efficiency.
Do not set the starting angle of the louvers too small during cooling or drying operation.
Otherwise, condensation may occur on the surface of the horizontal louver and cause
dew dripping.
During the operation, if the louvers can not swing normally, shut off the unit and unplug
for several minutes, then plug it again and restart the operation.
The horizontal louver may slightly vibrate during the operation. This is normal.
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 starting.
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 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
conditioner restarts in HEAT mode operation after defrosting.
