The following events may occur during normal operation.
1.
Compressor protection
The compressor cannot restart for 3-4 minutes after it stops.
2. Defrosting
Frost may be generated on the outdoor unit during heat cycle when the outdoor temperature is
low and the humidity is high resulting in lower heating efficiency of the air conditioner.
During this condition, the air conditioner will stop heating operation and start defrosting
automatically.
The time to defrost may vary from approximately 4 to 10 minutes according to the outdoor
temperature and the amount of frost built up on the outdoor unit.
3. White mist coming out from the indoor unit
White mist may come out due to a large temperature difference between the air inlet and air
outlet on COOL mode in an indoor environment that has a high relative humidity.
White mist may come out due to moisture generated from defrosting process when the air
conditioner restarts in HEAT mode operation after defrosting.
4. 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 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 happen due to louver restoring to its original position when the power is turned on.
5. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a prolonged period or
during first use of the unit.
6. A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, furniture,
or smoke.
7. The air conditioner turns to FAN mode from COOL or HEAT mode.
When indoor temperature reaches the temperature setting on the air conditioner, the compressor will
stop automatically, and the air conditioner will turn to FAN mode. The compressor will start again
when the indoor temperature rises on COOL mode or falls on HEAT mode to the set point.
