Compressor protection
•
The compressor cannot restart for 3 minutes after it stops.
Anti-cold air
•
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.
Defrosting
•
The indoor or outdoor fan stops running when defrosting.
•
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 periodically 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 condi-
tioner 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 flowing or coming to a stop.
•
You can also hear a low “squeak” sound when the compressor is running or has just stopped run-
ning. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the
temperature is changing.
•
A sound 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.
6. The air conditioner turns to FAN only mode from COOL or HEAT 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 to the 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.
