Do not place anything containing wa-
ter, like vases, on top of the unit.

Water entering the unit could damage the insula-
tion and therefore cause an electric shock.

The system should only be used for its original purpose
and not for anything else like, for instance, preservation of
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 wash the air-conditioner with wa-
ter.

This could cause an electric shock.

You should not expose any combus-
tion appliance directly to the air
stream of the air-conditioner.

The appliance may then work inadequately.

Do not place a combustible insecticide
or paint spray near the blower, nor aim it
directly at the system.

This may result in a fire.

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 sit on the outdoor unit nor put
anything on it.

If the unit falls down or things drop off it, people
could get hurt.

After a long period of use, check the unit's
support structure from time to time.

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
grill and filters.

Failure to observe this may result in injury through
insecure objects toppling over.

Consult your dealer for repairs to the
system.

Wrong repairs could cause an electric shock, fire, etc.

If you notice anything abnormal (smell of
burning, etc.), stop the system, turn off the
power switch and consult your dealer.

Continued use of the system in abnormal circum-
stances may result in malfunctioning, electric shock,
fire, etc.

If the air-conditioner is moved else-
where, contact your dealer or a pro-
fessional fitter.

Faulty installation may cause water leakage, elec-
tric shock, fire, etc.

 PRECAUTIONS FOR TRANSFER OR REPAIRS

DANGER

Safety precautions

CAUTION

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.

Do not touch the aluminum fins on the
air heat exchanger.

Failure to observe this may result in injury.

If you operate the system together with
a combustion appliance, you must regu-
larly ventilate the indoor air.

Insufficient ventilation may cause accidents due to
oxygen deficiency.

When you clean the system, stop the
unit and turn off the power switch.

Never clean the unit while the internal fan is rotating.
