Safety precautions

• Before starting to use the system, please read these “Safety precautions” carefully to ensure proper operation of the system.

• The safety precautions are classified as “

improper handling could lead to drastic result like death, serious injury, etc. Even precautions as shown in the column “
a serious problem, depending on the circumstances. Please observe these precautions with great care, since they are essential to your safety.

• Symbols which appear frequently in the text have the following meaning:

DANGER” and “ CAUTION”. Precautions as shown in the column “ DANGER” indicate that

CAUTION” might pose

Strictly prohibited Provide proper earthing

• When you have read this instruction manual, please keep it without missing. If someone else takes over as operator, make certain that the manual is
also passed on to the new operator.

Observe instructions with
great care

❚ INSTALLATION PRECAUTIONS

CAUTIONDANGER

The system is for domestic, residential
etc. use.

If used in severer environments, such
as an engineering workplace, the
equipment may function poorly.

The system must be installed by your
dealer or a qualified professional.

It is not advisable to install the system
by yourself, as faulty handling may
cause leakage of water, electric shock
or fire.

Do not install it where flammable gas
may leak.

Gas leaks may cause fire. If you do not install an earth leakage

Make sure to install the drain hose
properly so that all the water is
drained out.

Improper installation may lead to
water drop in the room resulting in
wet furniture.

Depending on the place of installation,
an earth leakage breaker may be neces­sary.

breaker, you may get an electric shock.

Make sure that the system has been
properly earthed.

Earth cables should never be connected
to a gas pipe, water pipe, lightning con­ductor or telephone earth cable. Incor­rect installation of the earth cable may
produce an electric shock.

❚ OPERATION PRECAUTIONS

DANGER

Do not expose yourself to the cooling
air for a long period.

Do not insert anything into the air inlet.

Store the remote control out of reach
of infants.

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 prohib­ited, as it may cause a breakdown or
fire.

Do not place a flammable insecticide or
paint spray near the blower, nor spray it
directly on the system.

This may result in a fire. The appliance may then work inad-

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 handle the switches with wet
hands.

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

Do not place anything containing wa­ter, like vases, on top of the unit.

This may cause injury, as the inter­nal fan rotates at high speed.

Failure to observe this may result in
the batteries being swallowed or
other accidents.

CAUTION

Do not swing from the indoor unit.

This may cause an electric shock. If the indoor unit falls down,

Do not wash the air-conditioner with wa­ter.

equately.

Do not install the system where the
airflow direction is aimed directly at
plants or animals.

Water entering the unit could dam­age the insulation and therefore
cause an electric shock.

you may get injured.

This could cause an electric shock.

This will damage their health.

❚ Safety precautions

Do not sit on the outdoor unit nor put
anything on it.

CAUTION

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

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.

Do not place household electrical appli­ances or household items under neath
the indoor or outdoor units.

Condensation falling from the unit
may stain objects and cause accidents
or electrical shock.

Do not control the system with main
power switch.

It can cause fire or water leakage. In
addition, the fan can start unexpect­edly, which can cause personal injury.

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

Never open the panel while the
internal fan is rotating.

If you do not repair any damage
right away, the unit may fall down
and cause personal injury.

Do not operate the system without the
air filter.

It can cause malfunction of the sys­tem due to clogging of the heat ex­changer.

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.

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 and may cause a break­down, smoke or fire.

It may result in injury.

Do not shut off the power supply im­mediately after stopping the opera­tion.

Wait at least 5 minutes, otherwise
there is a risk of water leakage or
breakdown.

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.

Contact your dealer to clean inside
the indoor unit, do not attempt to do
by yourself.

The use of a non-approved detergent
or improper washing method may
damage the unit’s plastic compo­nents and cause leaks. Damage,
smoke, or fire may also happen if the
detergent comes in contact with
electrical parts or the unit’s motor.

Stop the unit and turn off the power if
you hear thunder or there is a danger of
lightning.

It may damage the unit.

❚ PRECAUTIONS FOR RELOCATION OR REPAIRS

DANGER

Do not perform any repairs or modifica­tions by yourself. Consult the dealer if
the unit requires repair.

If you repair or modify the unit, it can
cause water leaks, electric shocks or
fire.

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

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

Consult your dealer for repairs.

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

If the air-conditioner fails to cool or warm the room, it may have a refrigerant
leakage. Contact your dealer.
If refrigerant needs to be added, check with your dealer for proper instructions.

The refrigerant used in your air-conditioner is safe. However, if refrigerant unexpectedly
leaks from the unit onto a fan heater, stove, hotplate or other heat source, harmful gases could
be generated.

In case the air-conditioner is relocated
elsewhere, contact your dealer or a
professional fitter.

Faulty installation may cause water
leakage, electric shock, fire, etc.
