3. Care and cleaning
A
B
3.1. Cleaning the filters and the indoor unit
Cleaning the filters
• Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap
the filters against a solid object to knock off dirt and dust.
• If the filters are especially dirty, wash them in lukewarm water. Take care to rinse
off any detergent thoroughly and allow the filters to dry completely before putting
them back into the unit.
Caution:
• Do not dry the filters in direct sunlight or by using a heat source, such as an
electric heater: this may warp them.
• Do not wash the filters in hot water (above 50°C), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit without
air filters can cause malfunction.
Caution:
• Before you start cleaning, stop operation and turn OFF the power supply.
• The air filter should be obtained locally. Be sure to check on the location and
the way of setting with the contractor when the unit perform a trial run. (Example) The air filter should be attached to the indoor unit’s air intake (rear
side of unit).

4. Troubleshooting
Before you call out a repair man, check the following table to see whether there is a simple solution to your problem.
[for wired remote controller]
Problem
Unit does not cool or heat very well.
The unit stops operating before arriving
at the set temperature in the heating
mode.
A white mist is expelled from the indoor
unit.
The indicators of the remote controller do
not light up when operated.
Clean the filter.
Frost forms when the outdoor temperature 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 humidity is
present in the room.
Turn on the power switch. “ · ” will be dis-
played.
Solution
CENTRALLY CONTROLLED is displayed in the remote controller.
The start and stop functions are not available just after restarting the unit.
“H0” is displayed in the remote controller.
An error code is displayed in the remote
controller.
The operating display of the wireless remote controller’s receiver is flashing.

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.
NOTE: The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and comes into contact
with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated.
Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.

A self-diagnostic function is being performed to preserve the air conditioner.
∗ Do not attempt to make repairs your-
self. Turn the main switch off and contact the dealer from whom you bought
the air conditioner. Provide him or her
with the name of the unit and the information displayed in the remote controller.
