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.

    A)  When heating has just started.

    B)  During 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 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.

Dust blowing out from the indoor unit.

This is happens when the air conditioner has not

been used for a long time or during its first use.

Smell emitting from the indoor unit.

This is caused by the indoor unit giving off smells

permeated from building materials, furniture,or 

smoke.

NOTE: 

For multi-split type air conditioners, one outdoor unit can be matched to different types of 

indoor units. All of the pictures in this manual are for demonstration purposes only. Your air 

conditioner may be slightly different, if similar in shape. The following pages introduce several kinds 

of indoor units that can be matched with the outdoor units.
