Operation does not start soon�
îš„ 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.
The ap does not start swinging
immediately�
• The air conditioner is adjusting the position of the ap.
The ap will start moving soon.
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.
îš„ Blowing sound
• This sound is generated when the ow of the
refrigerant in the air conditioner is switched over.
îš„ 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.
îš„ Whistling sound
• This sound is generated when refrigerant ows during
defrosting operation.
îš„ Clicking sound during operation or idle time
• This sound is generated when the refrigerant control
valves or the electrical parts operate.
îš„ 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.
The outdoor unit emits water or steam�
îš„In HEAT operation
• The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrosting operation.
îš„In COOL or DRY operation
• Moisture in the air condenses into water on the cool surface of the outdoor
unit piping and drips.
Operating sound is loud�
• When frost forms on the heat exchanger of the outdoor unit, the operating
sound level increases slightly.
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
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.
