FAQ
Indoor unit
The air conditioner stops generating
airfl ow during operation.
• Once the set temperature is reached, the airfl ow rate is
reduced and operation stopped in order to avoid
generating cool airfl ow (during heating) or in order to
keep the humidity from rising (during cooling).
Operation will resume automatically when the indoor
temperature rises or falls.
HEAT operation stops suddenly and a
fl 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.
Operation does not start soon.
When or any direct operation button
was pressed soon after operation was
stopped.
When the mode was reselected.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
Different sounds are heard.
A sound like fl owing water
• This sound is generated because the refrigerant in the
air conditioner is fl 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 fl 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 fl 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.
Outdoor unit
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
