Protection of the air conditioner
Compressor protection
•
The compressor cannot 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.
1. When heating has just started.
2. During defrosting.
3. 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 a heat cycle when outdoor temperature is low
and humidity is high resulting in lower heating efficiency in the air conditioner.
•
Under these conditions, the air conditioner will stop heating operations and start defrosting
automatically.
•
The time to defrost may vary from 4 to 10 minutes, depending the outdoor temperature and the
amount of frost buildup on the outdoor unit.
Auto-restart (some models)
In case of power failure, the system will immediately stop. When power returns, the operation light
on the indoor unit will flash. To restart the unit, press the On/Off button on the remote control. If the
system has an auto restart function, the unit will restart with the same settings.
White mist emerging from the indoor unit
•
A white mist may be generated due to a large temperature difference between air inlet and air
outlet on cool mode in places with high relative humidity.
•
A white mist may be generated due to moisture created in the defrosting process when the air
conditioner restarts in heat mode operation after defrosting.
Noise coming from 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 may also hear a low "squeaking" sound when the compressor is running or has just stopped
running. This is caused by tempera heat expansion and cold contraction of the plastic parts in the
unit when the temperature is changing.
•
A noise may be heard due to the louver restoring itself to its original position when power is first
turned on.
