Operating sound is loud.
•
When frost forms on the heat exchanger of the outdoor unit, the operating sound level
increases slightly.

Troubleshooting
These cases are not problems.
• The following cases are not air conditioner problems but have some reasons. You may just continue using it.
Indoor unit
Outdoor unit
HEAT operation stops suddenly
and a flowing sound is heard.
•
The outdoor unit is defrosting.
HEAT operation starts after the frost on the outdoor unit
has been removed. This can take about 4 to 12 minutes.
Operation does not start soon.
When the unit is turned on again soon after
being turned off.
When the mode was reselected.
•
This is to protect the air conditioner.
You should wait for about 3 minutes.
The flaps do not start swinging
immediately.
• The air conditioner is adjusting the position of the
flaps. The flaps will start moving soon.
Different sounds are 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.
• The refrigerant flows in the air conditioner even if the
air conditioner is not working when the indoor units
in other rooms are in 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.
Whistling sound
• This sound is generated when refrigerant flows
during defrosting operation.
Clicking sound during operation or idle time
•
This sound is generated when the refrigerant control
valves or the electrical parts operate.
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 air conditioner stops generating
airflow during HEAT operation.
• Once the set temperature is reached, the airflow rate
is reduced and operation stopped in order to avoid
generating cool airflow. Operation will resume
automatically when the indoor temperature falls.
The outdoor unit emits water or steam.
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.
