manufacturer or its service agent in order to avoid a hazard.

:

Be sure to disconnect the power supply plug from the power outlet.

: Be sure to shut off the power.

: Risk of fi re.

When installing, relocating, or servicing the unit, make sure

that no substance other than the specifi ed refrigerant (R32)

enters the refrigerant circuit.

• Any presence of foreign substance such as air can cause abnor­mal pressure rise and may result in explosion or injury.

• The use of any refrigerant other than that specifi ed for the system
will cause mechanical failure, system malfunction, or unit break­down. In the worst case, this could lead to a serious impediment
to securing product safety.

This 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.

Do not insert your fi nger, a stick, or other objects into the air

inlet or outlet.

• This may cause injury, since the fan inside rotates at high speeds
during operation.

In case of an abnormal condition (such as a burning smell),

stop the air conditioner and disconnect the power plug or turn
the breaker OFF.

• A continued operation in the abnormal state may cause a malfunc­tion, fi re, or electric shock. In this case, consult your dealer.

SAFETY PRECAUTIONS

WARNING

When the air conditioner does not cool or heat, there is a pos­sibility of refrigerant leakage. If any refrigerant leakage is found,
stop operations and ventilate the room well and consult your
dealer immediately. If a repair involves recharging the unit with
refrigerant, ask the service technician for details.

• The refrigerant used in the air conditioner is not harmful. Normally,
it does not leak. However, if refrigerant leaks and comes in contact
with fi re or heating part of such a fan heater, kerosene heater, or
cooking stove, it will create harmful gas and there is risk of fi re.

The user should never attempt to wash the inside of the indoor
unit. Should the inside of the unit require cleaning, contact
your dealer.

• Unsuitable detergent may cause damage to plastic material inside
the unit, which may result in water leakage. Should detergent
come in contact with electrical parts or the motor, it will result in
a malfunction, smoke, or fi re.

• The appliance shall be stored in a room without continuously
operating ignition sources (for example: open fl ames, an operat­ing gas appliance or an operating electric heater).

• Be aware that refrigerants may not contain an odour.

• Do not use means to accelerate the defrosting process or to
clean the appliance, other than those recommended by the
manufacturer.

• Do not pierce or burn.

• The unit may be damaged if lightning strikes.

After the air conditioner is used for several seasons, perform
inspection and maintenance in addition to normal cleaning.

• Dirt or dust in the unit may create an unpleasant odor, contribute
to growth of fungi, such as mold, or clog the drain passage, and
cause water to leak from the indoor unit. Consult your dealer for
inspection and maintenance, which require specialized knowledge
and skills.

Do not operate switches with wet hands.

• This may cause electric shock.

Do not clean the air conditioner with water or place an object that

contains water, such as a fl ower vase, on it.

• This may cause fi re or electric shock.

Do not step on or place any object on the outdoor unit.

• This may cause injury if you or the object falls down.

IMPORTANT

Dirty fi lters cause condensation in the air conditioner which will contribute

to the growth of fungi such as mold. It is therefore recommended to clean air

fi lters every 2 weeks.

For installation

WARNING

Consult your dealer for installing the air conditioner.

• It should not be installed by the user since installation requires
specialized knowledge and skills. An improperly installed air con­ditioner may cause water leakage, fi re, or electric shock.

Provide a dedicated power supply for the air conditioner.

• A non-dedicated power supply may cause overheating or fi re.

Do not install the unit where fl ammable gas could leak.

• If gas leaks and accumulates around the outdoor unit, it may cause
an explosion.

Earth the unit correctly.

• Do not connect the earth wire to a gas pipe, water pipe, lightning
rod, or a telephone ground wire. Improper earthing may cause
electric shock.

CAUTION

Install an earth leakage breaker depending on the installation

location of the air conditioner (such as highly humid areas).

• If an earth leakage breaker is not installed, it may cause electric
shock.

Ensure that the drain water is properly drained.

• If the drain passage is improper, water may drip down from the
indoor/outdoor unit, wetting and damaging the furniture.

In case of an abnormal condition

Immediately stop operating the air conditioner and consult your dealer.
