AFETY PRECAUTIONS
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, re, or electric shock.
Make sure the power plug is free of dirt and insert
it securely into the outlet.
A dirty plug may cause re 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 re or electric shock.
Do not turn the breaker OFF/ON or disconnect/con-
nect the power plug during operation.
This may create sparks, which can cause re.
After the indoor unit is switched OFF with the remote control-
ler, 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.
This could be detrimental to your health.
The unit should not be installed, relocated, or
repaired by the user.
An improperly handled air conditioner may cause re or
electric shock.

Do not insert your 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 burn-
ing 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, re, 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 re-
charging 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.
CAUTION
Do not touch the air inlet or the aluminum ns of
the indoor/outdoor unit.
This may cause injury.
Do not use insecticides or ammable sprays on
the unit.
This may cause a re or deformation of the unit.
Do not expose pets or houseplants to direct air ow.
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 dam-
age or malfunction.
Do not leave the unit on a damaged installation stand.
The unit may fall and cause injury.

AFETY PRECAUTIONS
CAUTION
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 re.
Do not charge or disassemble the batteries, and
do not throw them into a re.
This may cause the batteries to leak, or cause a re or explo-
sion.
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.
This may cause deterioration of quality, or harm to animals
and plants.
Do not expose combustion appliances to direct
air ow.
This may cause incomplete combustion.
Before cleaning the unit, switch it OFF and discon-
nect 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, discon-
nect the power plug or turn the breaker OFF.
The unit may accumulate dirt, which may cause overheating
or re.
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 uid comes in contact with your skin or
clothes, wash them thoroughly with clean water.
If the battery uid 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 sea-
sons, perform inspection and maintenance in ad-
dition to normal cleaning.
Dirt or dust in the unit may create an unpleasant odor 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 ower
vase, on it.
This may cause 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.
For installation
WARNING
Consult your dealer for installing the air condi-
tioner.
It should not be installed by the user since installation requires
specialized knowledge and skills. An improperly installed
air conditioner may cause water leakage, re, or electric
shock.
Provide a dedicated power supply for the air conditioner.
A non-dedicated power supply may cause overheating or
re.
Do not install the unit where ammable gas could leak.
If gas leaks and accumulates around the unit, it may cause
an explosion.
Ground the unit correctly.
Do not connect the ground wire to a gas pipe, water pipe,
lightning rod, or a telephone ground wire. Improper grounding
may cause electric shock.
CAUTION
Install a Ground Fault Interrupt (GFI) circuit breaker
depending on the installation location of the air
conditioner (such as highly humid areas).
If the Ground Fault Interrupt (GFI) 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.
