Observe instructions with
great care
❚ INSTALLATION PRECAUTIONS
DANGER
The system is meant for domestic, residential etc. use.
If used in inferior environments, such as an engineering workplace, the equipment
may function poorly.
Do not install near places where inflammable gas may leak.
LPG
Gas leaks may cause fire.
Make sure that you drain the hose properly, so that all the
water has dripped out.
The system must be installed by your dealer or a qualified professional.
It is not advisable to install the system yourself, as faulty handling may cause leakage of water, electric shock or fire.
CAUTION
Depending on the place of installation, a circuit breaker may
be necessary.
If you don’t fit a circuit breaker, you may cause an electric shock.
Make sure that the system has been properly earthed.
Negligence may cause flooding in the room resulting in wet furniture.
❚ OPERATION PRECAUTIONS
Do not expose yourself to the cooling
air for prolonged periods.
This could affect your physical condition and cause
health problems.
Only use approved fuses.
Use of steel or copper wire instead of an approved
fuse is strictly forbidden, as it may cause a breakdown
or fire.
Do not insert anything into the air inlet.
This may cause injury, as the internal fan rotates at
high speed.
Do not handle the switches with wet
hands.
This may cause an electric shock.
Earth cables should never be connected to a gas pipe, municipal water pipe, lightning conductor or telephone earth cable. Incorrect installation of the earth cable
may produce an electric shock.
DANGER
Store the remote control out of reach
of infants.
Failure to observe this may result in the batteries
being swallowed or other accidents.
CAUTION
Don’t swing from the system.
If the system falls down,
you may get injured.

or paint spray near the blower, nor aim it
directly at the system.
This may result in a fire.
The system should only be used for its original purpose
and not for anything else like, for instance, preservation of
You should not expose any combustion appliance directly to the air
stream of the air-conditioner.
The appliance may then work inadequately.
Do not place anything containing water, like vases, on top of the unit.
food, plants or animals, precision devices or works of art.
The system is only intended for use in ordinary domestic rooms.
Any other use of the system may damage the quality of food, etc.
Do not sit on the outdoor unit nor put
anything on it.
Water entering the unit could damage the insulation and therefore cause an electric shock.
After a long period of use, check the unit's
support structure from time to time.
Do not wash the air-conditioner with water.
This could cause an electric shock.
Do not install the system at a place
where the air stream of the blower is
aimed directly at plants or animals.
This will damage their health.
Do not touch the aluminum fins on the
air heat exchanger.
If the unit falls down or things drop off it, people
could get hurt.
If you operate the system together with
a combustion appliance, you must regularly ventilate the indoor air.
Insufficient ventilation may cause accidents due to
oxygen deficiency.
If you don't repair any damage straightaway, the
unit may fall down and cause personal injury.
Stand firmly on a stepladder or other
stable object when removing the inlet
panel and filters.
Failure to observe this may result in injury through
insecure objects toppling over.
Do not place objects near the outdoor
unit or allow leaves to gather around the
unit.
If there are objects or leaves around the outdoor unit,
small animals may enter unit and contact electrical
parts resulting in break down, emission of smoke or
flame.
❚ PRECAUTIONS FOR TRANSFER OR REPAIRS
DANGER
Consult your dealer for repairs to the
system.
If the air-conditioner is moved elsewhere, contact your dealer or a professional fitter.
Failure to observe this may result in injury.
When you clean the system, stop the
unit and turn off the power switch.
Never clean the unit while the internal fan is rotating.
If you notice anything abnormal (smell of
burning, etc.), stop the system, turn off the
power switch and consult your dealer.
Wrong repairs could cause an electric shock, fire, etc.
Faulty installation may cause water leakage, electric shock, fire, etc.
