TROUBLESHOOTING
Case Explanation
 The unit does not receive
signals from remote
controller or has a limited
operating range.
• Signal communication may be disabled if an electronic-
starter-type uorescent lamp (such as inverter-type lamps) is
in the room. Consult your dealer if that is in this case.
• The remote controller may not function correctly if the
transmitter is exposed to direct sunlight.
 Other electronic devices
start operating.
• If the remote controller activates other electronic devices,
move them away or consult your dealer.
The aps do not start swinging
immediately.
• The air conditioner is adjusting the aps position.
• The aps will start moving soon.
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.
The HEAT operation stops
suddenly and a owing sound
is heard.
• The outdoor unit is taking away the frost. The HEAT operation
starts after the frost on the outdoor unit is removed.
You should wait for about 4 to 12 minutes.
Hot air does not ow 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.)
The ON/OFF TIMER does not
operate according to the settings.
• Check if the ON/OFF TIMER correct. The actual length of timer
can be differ from user setted time for approx. 10 minutes.
A sound is heard.
 A sound like a ow of 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 heard when the water is pumped out from the air
conditioner in cooling or drying operation.
 Blowing sound • This sound is generated when the ow of the refrigerant in
the air conditioner is switched over.
 Whistling sound • This sound is generated when refrigerant ows during
defrosting operation.
 Ticking sound •
This sound is generated when the size of the air conditioner
slightly expands or shrinks as a result of temperature changes.
 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.
Air does not come out.  In COOL or DRY mode
•
If COOL/DRY operation is started with airow settings on
“AUTO”, the indoor unit will initially deodorise, which functions
to suppress any internal odours. As a result, the indoor unit
will not emit air immediately. (Wait for about 1 minute.)
The air conditioner continues
operating even after COOL or
DRY operation is stopped.
• The air conditioner is operating in MOLD PROOF mode.
When you want to stop MOLD PROOF operation midway,
