A sound is heard.

A sound like a flow of 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 heard when the water is pumped out
from the air conditioner in cooling or drying 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.
• Sound is heard when the vertical swing flaps and
the horizontal swing flaps move.
• When the air conditioner is operating in a quiet
environment and the airflow rate of the indoor unit is
set to Quiet Mode or Low Mode, the motion of the
swing flaps may cause sound.

Blowing sound

Rotating machinery causes sound
• This sound is generated when the flow of the
refrigerant in the air conditioner is switching.

Ticking sound
• This sound is generated when the size of the air
conditioner slightly expands or shrinks 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.

In HEAT operation
The frost on the outdoor unit melts into water or steam when the
•
air conditioner is in defrost operation.
In COOL or DRY operation
Moisture in the air condenses into water on the cool surface of outdoor
•
unit piping and drips.
