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 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.
9. Water leakage
Water leakage 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.
10. Heat mode
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 will decrease accordingly. At the same time, heat loading of the air conditioner
will increase 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.
11. Auto-restart function
Power failure during operation will stop the unit completely.
When the power restores, the unit will restart automatically with all the previous settings preserved
by the memory function.
8. The air conditioner runs function after turning off the unit.
When turning off the unit under COOL and DRY mode, the air conditioner will run
function for 7-10 minutes.
then the operation will be stopped and the unit will turn off automatically.

If turning off the unit when HEAT mode, the unit will continue operating for about 30 seconds
at LOW fan speed,
