SAFETY 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, 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 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 pro-
longed 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 fire or
electric shock.
Do not insert your finger, 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, 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.
• 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 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 dam-
age or malfunction.
Do not leave the unit on a damaged installation stand.
• The unit may fall and cause injury.
