Safety precautions

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

system.

•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.

❚INSTALLATION PRECAUTIONS

❚OPERATION 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.

CAUTION

WARNING

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:

WARNING

CAUTION

Improper handling could lead to drastic result like death, serious injury, etc.

Might pose a serious problem, depending on the circumstances.

Strictly prohibited Provide proper earthing

Observe instructions with

great care

•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.

•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.

•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.

•Store the remote control out of reach of infants.

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

•Only use approved fuses.

Use of steel or copper wire instead of an approved

fuse is strictly prohibited, as it may cause a break-

down 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.

CAUTION

•

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 supervi-

sion 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.

❚Safety precautions

❚PRECAUTIONS FOR RELOCATION OR REPAIRS

WARNING

CAUTION

•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 in-

stance, 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 di-

rection 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 supply 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 supply.

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 im-

proper 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.

•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 profes-

sional 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 supply 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 dizzi-

ness and headache, or deterioration of heart func-

tion 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 gener-

ated.
