Troubleshooting 

These cases are not problems. 

The following cases are not air conditioner troubles but have some reasons. You may just 

continue using it. 

Case 

Explanation 

Operation does not start soon. 

• This is to protect the air conditioner. 

• When "ON/OFF" button was 

You should wait for about 3 minutes. 

pressed soon after operation 

was stopped. 

• When the mode was

reselected.

Air does not come out. 

• If the operation is started when the airflow setting is "Auto", the

SMELL PROOF operation starts running to prevent unpleasant

odour inside the indoor unit. Wait for about 1 minute. (Except when

POWER CHILL operation is set)

• Refer to 

"Adjusting the Airflow Rate/ SMELL PROOF Operation". 

The flaps do not start 

• The air conditioner is adjusting the position of the flaps. The flaps

swinging immediately. 

will start moving soon.

Operation stopped suddenly. 

• To  protect the system, the air conditioner may stop operating after

(OPERATION lamp is on) 

sudden large voltage fluctuations.

It automatically resumes operation in about 3 minutes.

Voltage range protection: 130V-285V

A sound is heard. 

A sound like flowing water 

• This sound is generated because the refrigerant in the air 

conditioner is flowing.

• This is a pumping sound of the water in the air conditioner and

can be heard when the water is pumped out from the air

conditioner during COOL or DRY operation.

■ 

Blowing sound

• This sound is generated when the flow of the refrigerant in the air

conditioner is switched over.

Ticking sound 

• This sound is generated when the cabinet and frame of the air

conditioner slightly expand or shrink as a result of temperature

changes.

■ 

Clopping sound 

• This sound is heard from the inside of the air conditioner when

the exhaust fan is activated while the room doors are closed.

Open the window or turn off the exhaust fan.

The outdoor unit emits water 

■ 

In COOL or DRY operation 

or steam. 

• Moisture in the air condenses into water on the cool surface of

the outdoor unit piping and drips.

Mist comes out of the indoor 

• This happens when unit cooling in high humidity or if unit exposed

unit. 

to excessive oil, dust due to this irregular temperature may occur.
