The air conditioner stops
generating airow during HEAT
operation.
• Once the set temperature is reached, the airow
rate is reduced and operation stopped in order
to avoid generating a cool airow. Operation will
resume automatically when the indoor
temperature falls.
Commonly occurring sounds.
 A sound like owing water
• This sound is generated because the refrigerant in the air
conditioner is owing.
• 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.
• This sound is generated during COOL operation on outdoor
ambient lower than 12°C when outdoor fan stop for keep
pressure.
 Blowing sound
• This sound is generated when the ow 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 ows 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.
 Hissing/Cracking sound
• The sound of the streamer discharge. It is not a malfunction.
 Rotating machinery causes sound

and the airow rate of the indoor unit is set to Quiet Mode or
Low Mode, the motion of the swing ap may cause sound.

 In HEAT operation
• The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrosting operation.

of the outdoor unit piping and drips.
HEAT operation stops suddenly
and a owing sound is heard.

starts after the frost on the outdoor unit has
been removed.
