Marks and their meanings
WARNING :
Incorrect handling could cause serious hazard, such as
death, serious injury, etc. with a high probability.
CAUTION :
Incorrect handling could cause serious hazard depending
on the conditions.
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.

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.

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.

throw them into a fi re.
• This may cause the batteries to leak, or cause a fi 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.

power plug or turn the breaker OFF.
• The unit may accumulate dirt, which may cause overheating
or fi re.
Replace all batteries of the remote controller with new ones
of the same type.
