ISSUE

Possible Causes

Unit does not turn on when pressing 

ON/OFF

The unit has a 3-minute protection feature that prevents the unit from overloading. The unit 

cannot restart within three minutes of being turned off.

The unit changes from 

COOL/HEAT

 mode to 

FAN

 mode

The unit may change its setting to prevent frost from forming on the unit. Once the temperature 

increases, the unit starts operating in the previously selected mode again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit 

continues operating when the temperature fluctuates again.

The indoor unit emits white mist

In humid regions, a large temperature difference between the room's air and the conditioned air 

can cause white mist.

Both the indoor and outdoor units emit white 

mist

When the unit restarts in 

HEAT

 mode after defrosting, white mist may be emitted due to moisture 

generated from the defrosting process.

The indoor unit makes noises

A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in 

HEAT

 mode due to expansion and con-

traction of the unit's plastic parts.

Both the indoor unit and outdoor unit make 

noises

Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing 

through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise 

is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by 

temperature changes during operation can cause squeaking noises.

The outdoor unit makes noises

The unit makes different sounds based on its current operating mode.

Dust is emitted from either the indoor or 

outdoor unit

The unit may accumulate dust during extended periods of non-use, which will be emitted when 

the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.

The unit emits a bad odor

The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) 

which will be emitted during operations.
The unit's filters have become moldy and should be cleaned.

The outdoor unit's fan does not operate

During operation, the fan speed is controlled to optimize product operation.

Operation is erratic, unpredictable, or unit is

unresponsive

Interference from cell phone towers and remote boosters may cause the unit to malfunction. In 

this case, try the following:

• Disconnect the power, then reconnect.

• Press ON/OFF on remote control to restart operation.
