FAQ
Indoor unit
The flap does not start swinging
immediately.
• The air conditioner is adjusting the position of the flap.
The flap will start moving soon.
The air conditioner stops generating
airflow during HEAT operation.
• Once the set temperature is reached, the airflow rate is
reduced and operation stopped in order to avoid
generating a cool airflow. Operation will resume
automatically when the indoor temperature falls.
HEAT operation stops suddenly and
a flowing 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.
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
unit piping and drips.
Different sounds are heard.
„ A sound like flowing 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 can be heard when the water is pumped out from the air
conditioner during COOL or DRY operation.
• Refrigerant flows inside the air conditioner even when
one indoor unit is not in operation if the other indoor
unit is in operation.
„ Blowing sound
• This sound is generated when the flow 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 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.
„ Rotating machinery causes sound
• 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.
* Appearance of the outdoor unit may
differ from some models.
