Troubleshooting
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
defrost operation.
■ In COOL or DRY operation
• Moisture in the air condenses into water on
the cool surface of outdoor unit piping and
drips.
The air conditioner does not
operate.
(OPERATION lamp is off.)
• Hasn't a breaker turned off or a fuse blown?
• Isn't it a power failure?
• Are batteries set in the remote controller?
• Is the timer setting correct?
Hot air does not flow out soon after
the start of HEAT operation.
• The air conditioner is warming up.
You should wait for 1 to 4 minutes.
(The system is designed to start discharging
air only after it has reached a certain
temperature.)

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 it is 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.
■ Blowing sound
• This sound is generated when the flow of the
refrigerant in the air conditioner is switched
over.
■ Pinging 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.
