●OPERATING INSTRUCTIONS ●
SAFETY PRECAUTIONS
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 safe. Normally, it does not leak. However, if refrigerant
leaks and comes in contact with a heat source such as a fan heater, kerosene heater, or cooking
stove, it will create a harmful gas and there is risk of fire.
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 fire.
• The appliance shall be stored in a room without continuously operating ignition sources (for example:
open flames, 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 indoor unit must be installed in rooms which exceed the floor space specified. Please
consult your dealer.
CAUTION
Do not touch the air inlet or the aluminum fins of the indoor/outdoor unit.
• This may cause injury.
Do not use insecticides or flammable sprays on the unit.
• This may cause a fire or deformation of the unit.
Do not expose pets or houseplants to direct airflow.
• This may cause injury to the pets or plants.
Do not place other electric appliances or furniture under the indoor/outdoor unit.
• Water may drip down from the unit, which may cause damage or malfunction.
Do not leave the unit on a damaged installation stand.
• The unit may fall and cause injury.
Do not step on an unstable bench to operate or clean the unit.
• This may cause injury if you fall down.
Do not pull the power cord.
• This may cause a portion of the core wire to break, which may cause overheating or fire.
Do not charge or disassemble the batteries, and do not throw them into a fire.
• This may cause the batteries to leak, or cause a fire or explosion.
Do not operate the unit for more than 4 hours at high humidity (80% RH or more) and/or with
windows or outside door left open.
• This may cause the water condensation in the air conditioner, which may drip down, wetting or
damaging the furniture.
• The water condensation in the air conditioner may contribute to growth of fungi, such as mold.
Do not use the unit for special purposes, such as storing food, raising animals, growing plants,
or preserving precision devices or art objects.
• This may cause deterioration of quality, or harm to animals and plants.
Do not expose combustion appliances to direct airflow.
• This may cause incomplete combustion.
Never put batteries in your mouth for any reason to avoid accidental ingestion.
• Battery ingestion may cause choking and/or poisoning.
Before cleaning the unit, switch it OFF and disconnect the power plug or turn the breaker OFF.
• This may cause injury, since the fan inside rotates at high speeds during operation.
When the unit will be unused for a long time, disconnect the power plug or turn the breaker OFF.

SAFETY PRECAUTIONS
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, fire, or electric shock.
Provide a dedicated power supply for the air conditioner.
• A non-dedicated power supply may cause overheating or fire.
Do not install the unit where flammable 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 earth 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.
For installation
IMPORTANT
Dirty filters cause condensation in the air conditioner which will contribute to the growth of fungi such as mold. It is
therefore recommended to clean air filters every 2 weeks.
If the battery fluid comes in contact with your skin or clothes, wash them thoroughly with
clean water.
• If the battery fluid comes in contact with your eyes, wash them thoroughly with clean water and
immediately seek medical attention.
Ensure that the area is well-ventilated when the unit is operated together with a combustion
appliance.
• Inadequate ventilation may cause oxygen starvation.
Turn the breaker OFF when you hear thunder and there is a possibility of a lightning strike.
• 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
flower vase, on it.
• This may cause fire 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.
