Safety precautions

Before starting to use the system, please read these “Safety precautions” carefully.

When you have read this instruction manual, please keep it without missing.

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

Strictly prohibited Observe instructions with

great care Provide positive earthing

WARNING Improper handling could lead to drastic result

like death, serious injury, etc. CAUTION Might pose a serious problem, depending on

the circumstances.

Please observe these precautions with great care, since they are essential to your safety.

❚INSTALLATION PRECAUTIONS

WARNING

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.

CAUTION

Do not install it where ﬂammable gas may leak.

Gas leaks may cause ﬁre.

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

If you do not install an earth leakage breaker, you may get an electric shock.

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.

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.

❚PRECAUTIONS FOR RELOCATION OR REPAIRS

WARNING

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.

Consult your dealer for repairs.

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

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.

If you notice anything abnormal (smell of burning, etc.), stop the system, turn off the power source

and consult your dealer.

Continued use of the system in abnormal circumstances may result in malfunctioning, 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.

If the refrigerant comes in contact with the bare skin, it may cause cold injury.

If the refrigerant gas is inhaled excessively, it may cause deterioration of nerve function like dizziness and headache, or deterioration of heart

function like irregular heartbeat and heart palpitation temporarily. If refrigerant unexpectedly leaks from the unit onto a fan heater, stove,

hotplate or other heat source, harmful gases could be generated.

❚OPERATION PRECAUTIONS

WARNING

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

This could affect your physical condition and cause health problems.

Do not insert anything into the air inlet.

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

The appliance is not intended for use by persons (including children) with reduced physical,

sensory or mental capabilities, or lack of experience and knowledge, unless they have been given

supervision or instruction concerning use of the appliance by a person responsible for their

safety.

Children should be supervised to ensure that they do not play with the appliance.

Store the remote control out of reach of infants.

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

CAUTION

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 handle the switches with wet hands.

This may cause an electric shock.

Do not swing from the indoor unit.

If the indoor unit falls down,you may get injured.

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.

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

The appliance may then work inadequately.

Do not wash the air-conditioner with water.

This could 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 place anything containing water, like vases, on top of the unit.

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

Do not install the system where the airﬂow direction 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 do not repair any damage right away, the unit may fall down and cause personal injury.

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

It may result in injury.

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 operate the system without the air ﬁlter.

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

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

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

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.

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.

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.

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

Never open the panel while the internal fan is rotating.

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 break-down,

smoke or ﬁre.

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.
