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
The air conditioner stops
generating airflow during HEAT
operation.
HEAT operation stops suddenly
and a flowing sound is heard.
Operation does not start soon.
• When "ON/OFF" button was pressed
soon after operation was stopped.
• When the mode was reselected.
Air does not come out.
The flap does not start swinging
immediately.
Operation stopped suddenly.
(OPERATION lamp is on )
A sound is heard.
The outdoor unit emits water or
steam.
• Once the set temperature is reached, the airflow rate is reduced and
operation stopped in order to avoid generating a cool airflow. Operation will
resume automatically when the indoor temperature falls.
• The outdoor unit is defrosting. HEAT operation starts after the frost on the
outdoor unit has been removed. This can take about 20 minutes.
• In HEAT operation mode, if the outdoor temperature is above/below the
temperature range indicated under "Operating conditions", a safety device
will trip disabling operation.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
• If the operation is started when the SMELL PROOF operation is set, the
SMELL PROOF operation starts running to prevent unpleasant odour inside
the indoor unit. Wait for about 1 minute. (Except when POWERFUL
operation is set )
■ In HEAT operation
• The air conditioner is warming up. Wait for about 1 to 4 minutes.
• During defrosting operation, hot air does not flow out of the indoor unit.
• The air conditioner is adjusting the position of the flap. The flap will start
moving soon.
• To protect the system, the air conditioner may stop operating after sudden
large voltage fluctuations.
It automatically resumes operation in about 3 minutes.
Voltage range protection: 130V-265V
■ 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 condi-
tioner 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.
■ Whistling sound
• This sound is generated when refrigerant flows during defrosting operation.
■ 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.
■ In HEAT operation
• The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrosting operation.
■ In COOL or DRY operation
• Moisture in the air condenses into water on the cool surface of the outdoor
unit piping and drips.
