Indoor unit
Outdoor unit
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 3minutes.
For COOLING ONLY models (outdoor unit: RK
models) using facility settings
•
For the purposes of protecting the compressor, it can take up
to 3 hours for operation to begin after the unit is turned on.
The aps do not start swinging
immediately�
• The air conditioner is adjusting the position of the aps.
The aps will start moving soon.
HEAT operation stops suddenly and
a owing 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.
The air conditioner stops generating
airow during HEAT operation.
• Once the set temperature is reached, the airow rate is
reduced and operation stopped in order to avoid
generating a cool airow. Operation will resume
automatically when the indoor temperature falls.
Operating sound is loud�
• When frost forms on the heat exchanger of the outdoor unit, the operating sound level
increases slightly.
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.
Different sounds are heard�
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.
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
