WARNING
Do not connect the power cord to an intermediate point,
use an extension cord, or connect multiple devices to a
single AC outlet.
• This may cause overheating, fire, or electric shock.
Make sure the power plug is free of dirt and insert it securely into the outlet.
• A dirty plug may cause fire or electric shock.
Do not bundle, pull, or modify the power cord, and do not
apply heat or place heavy objects on it.
• This may cause fire or electric shock.
Do not turn the breaker OFF/ON or disconnect/connect the
power plug during operation.
• This may create sparks, which can cause fire.
• After the indoor unit is switched OFF with the remote controller, make sure to turn the breaker OFF or disconnect the
power plug.
Do not expose your body directly to cool air for a prolonged
length of time.
• Thiscouldbedetrimentaltoyourhealth.
The unit should not be installed, relocated, or repaired
by the user.
• An improperly handled air conditioner may cause fire or
electric shock.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental

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.
• Acontinuedoperationintheabnormalstatemaycausea
malfunction, fire, or electric shock. In this case, consult your
dealer.
When the air conditioner does not cool or heat, there is
a possibility of refrigerant leakage. In this case, consult
your dealer. If a repair involves recharging the unit with
refrigerant, ask the service technician for details.
• Therefrigerantusedintheairconditionerissafe.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.
CAUTION
Do not touch the air inlet or the aluminum fins of the
indoor/outdoor unit.
• Thismaycauseinjury.
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.
• Thismaycauseinjurytothepetsorplants.
Do not place other electric appliances or furniture under

SAFETY PRECAUTIONS
CAUTION
Do not operate switches with wet hands.
• This may cause electric shock.
Do not step on an unstable bench to operate or clean the
unit.
• This may cause injury if you fall down.
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 pull the power cord.
• This may cause a portion of the core wire to break, which may
cause overheating or fire.
Do not step on or place any object on the outdoor unit.
• This may cause injury if you or the object falls down.
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 a long time at high humidity (80%
RH or more), such as with a door or window left open.
• The water condensation in the air conditioner may drip down,
wetting or damaging the furniture.
Do not use the unit for special purposes, such as storing
food, raising animals, growing plants, or preserving precision devices or art objects.
• Thismaycausedeteriorationofquality,orharmtoanimals
andplants.
Do not expose combustion appliances to direct airflow.
• Thismaycauseincompletecombustion.
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
speedsduringoperation.
When the unit will be unused for a long time, disconnect the
power plug or turn the breaker OFF.
• The unit may accumulate dirt, which may cause overheating
or fire.
Replace all batteries of the remote controller with new ones
of the same type.
• Using an old battery together with a new one may cause
overheating, leakage, or explosion.
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.
For installation
WARNING
Consult your dealer for installing the air conditioner.
• Itshouldnotbeinstalledbytheusersinceinstallationrequires
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 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
Immediatelystopoperatingtheairconditionerandconsultyourdealer.
Turn the breaker OFF when you hear thunder and there is a
