4. Troubleshooting

Before you call out a repair man, check the following table to see whether there is a simple solution to your problem.
Problem
Unit does not cool or heat very well.
The unit stops operating before ar-
riving at the set temperature in the
heating mode.
A white mist is expelled from the in-
door unit.
The indicators of the remote control-
ler do not light up when operated.
CENTRALLY CONTROLLED is dis-
played in the remote controller.
NOTE: After a power cut, the unit will not restart automatically. You will have to restart it by pressing the POWER - ON/OFF button on the remote controller.
If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the
nature of the problem. Do not try to fix the unit yourself.
In any of the following cases, turn off the main power switch
and contact your local dealer for service:
• The operation lamp (on the main unit) flashes.
• The switches do not work properly.
• The circuit breaker trips frequently (or the fuse blows frequently).
• Water has accidentally been splashed into the unit.
• Water leaks from the unit.
• Something is accidentally dropped into the air-conditioner.
• An unusual noise is heard during operation.
The following do not indicate any malfunction:
Odours: smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit.
Sound of liquid flowing inside indoor unit: this can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit.
Ticking sound coming from indoor unit: this can occur when cooling or heating has just begun or has just stopped. It is caused by the indoor unit shrinking
or expanding slightly due to the change in temperature.
The message "CENTRALLY CONTROLLED" appearing on the LCD panel: from time to time, this message may come up on the LCD panel. This does not
indicate any malfunction.
Solution
Clean the filter.
Frost forms when the outdoor tem-
perature is low and humidity is high.
Wait for about 10 minutes for the frost
to melt.
This may occur just after the unit is
turned on when a high level of hu-
midity is present in the room.
Turn on the power switch. " " will be
displayed.
The start and stop functions of the
remote controller are not available
when the CENTRALLY CONTROL-
LED message is lit.
Problem
The start and stop functions are not
available just after restarting the unit.
"H0" is displayed in the remote con-
troller.
An error code is displayed in the re-
mote controller.
The operating display of the wireless
remote controller's receiver is flash-
