1.2. During operation
Caution:
•
•
•
Do not use any sharp object to push the buttons, as this may
damage the remote controller.
Do not twist or tug on the remote controller cord as this may dam-
age the remote controller and cause malfunction.
Never block or cover the indoor or outdoor unit’s intakes or out-
lets. Tall items of furniture underneath the indoor unit, or bulky
items such as large boxes placed close to the outdoor unit will
reduce the unit’s efficiency.
Warning:
•
Do not splash water over the unit and do not touch the unit with
wet hands. An electric shock may result.

1. Safety Precautions
1.2. During operation
Warning:
•
•
•
Do not remove the front panel or the fan guard from the outdoor
unit when it is running. You could be injured if you touch rotat-
ing, hot or high-voltage parts.
Never insert fingers, sticks etc. into the intakes or outlets, other-
wise injury may result, since the fan inside the unit rotates at
high speed. Exercise particular care when children are present.
If you detect odd smells, stop using the unit, turn off the power
switch and consult your dealer. Otherwise, a breakdown, electric
shock or fire may result.
•
•
Do not over-cool. The most suitable inside temperature is one
that is within 5°C of the outside temperature.
Do not leave handicapped people or infants sitting or standing in
the path of the airflow from the air-conditioner.This could cause
health problems.
Caution:
•
•
Do not direct the airflow at plants or caged pets.
Ventilate the room frequently. If the unit is operated continuously
in a closed room for a long period of time, the air will become
stale.
1.3. Disposing of the unit
Warning:
When you need to dispose of the unit, consult your dealer. If pipes
are removed incorrectly, refrigerant (fluorocarbon gas) may blow out
and come into contact with your skin, causing injury. Releasing re-
frigerant into the atmosphere also damages the environment.

5. Tips for best results
6. Care and cleaning
Keep the filters clean
Dirty or clogged filters reduce the flow of air, making the unit less efficient.
Very dirty filters may even cause damage to the unit. Remove and clean
the filters at least once a week (more often, in very dusty locations). Using
a vacuum cleaner is an ideal way to clean the filters.
Let fresh air into the room from time to time
Open the windows and ventilate the room now and then, otherwise the
room will become musty.
Eliminate heat sources
When cooling the room, draw the curtains to keep out direct sunlight. Keep
doors and windows fully closed, and avoid opening doors more often than
necessary.
Do not over-cool
The air-conditioner works most efficiently when cooling the room to a tem-
perature within 5˚C of the outdoor temperature.
In COOL mode, for every 1˚C you increase the desired temperature set-
ting, you will save about 10% on electricity costs.

Caution:
•
•
Always turn off the power, first on the remote controller and then
the main switch, before cleaning or servicing the unit.
When installing or removing the filter or front panel, do not stand
on an unsteady surface.You may fall and injure yourself. Be also
careful not to let dust fall into your eyes.

6. Care and cleaning
6.1. 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.

6.4. Pre-season checks
s Remove the protective cover from the outdoor unit.
s Check that the outdoor unit is properly installed.
s Check that the outdoor unit’s ground wire is properly attached.
s Check that the intakes and outlets on both the indoor and out-
door units are free of any obstruction.
s Check that the drain hose is not blocked, that there are no kinks
in it, and that it is correctly installed.
s Check that the filters are installed in the indoor unit. Operating
the air-conditioner without filters can damage it.
Caution:
The first time you use the air-conditioner after a long break (e.g. the
first hot day of summer), turn on the main power at least twelve hours
before you turn on the unit using the POWER ON/OFF button. This
will assist trouble-free operation.

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 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.
Warning:
If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a refrigerant
leak. Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.
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.
