S
AFETY PRECAUTIONS
Do not turn the breaker OFF except the case of burning
smell, or when performing maintenance or inspection.
• The refrigerant leakage cannot be detected, and this may
cause a fi re.
Do not install the unit in a place where smoke, gas, or
chemicals may fi ll.
• Do not use any gas equipment for propane, butane or
methane, sprays such as bug killer, and paint etc., near by
the indoor unit.
• The refrigerant sensor reacts to it and displays an error. This
may cause the unit not to operate.
(Procedure in case of refrigerant leakage)
If the refrigerant leaks, extinguish a fi re such as a heater,
and ventilate the room adequately by opening the window.
• Then contact your dealer.
• The indoor unit spreads the refrigerant by FAN mode to
prevent a fi re. Do not turn the breaker OFF during this situ-
ation.
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.
When the air conditioner does not cool or heat, there is a
possibility of refrigerant leakage. If any refrigerant leakage
is found, ventilate the room well and consult your dealer
immediately. Do not turn the breaker OFF. If a repair in-
volves 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.
This unit should be installed in rooms which exceed the
fl oor space specifi ed in outdoor unit installation manual.

explosion.
Do not operate the unit for more than 4 hours at high hu-
midity (80% RH or more) and/or with windows or outside

• 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 preci-
sion devices or art objects.
• This may cause deterioration of quality, or harm to animals
and plants.
Do not expose combustion appliances to direct airfl ow.
• 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.
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 fl uid comes in contact with your skin or
clothes, wash them thoroughly with clean water.
• If the battery fl 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.

a possibility of a lightning strike.
• The unit may be damaged if lightning strikes.
After the air conditioner is used for several seasons, per-
form inspection and maintenance in addition to normal
cleaning.
• Dirt or dust in the unit may create an unpleasant odor, con-
tribute 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 con-
tribute to the growth of fungi such as mold. It is therefore recommended
to clean air fi lters every 2 weeks.
