CAUTION :
Incorrect handling could cause serious hazard, such as
death, serious injury, etc. with a high probability.
Incorrect handling could cause serious hazard depending
on the conditions.
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, fi 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 fi re or electric shock.
Do not bundle, pull, damage, or modify the power cord, and do
not apply heat or place heavy objects on it.
• This may cause fi re 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 fi re.
• 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.
• This could be detrimental to your health.
The unit should not be installed, relocated, disassembled,
altered, or repaired by the user.
• An improperly handled air conditioner may cause fi re, electric
shock, injury, or water leakage, etc. Consult your dealer.
• If the power supply cord is damaged, it must be replaced by the
manufacturer or its service agent in order to avoid a hazard.
When installing, relocating, or servicing the unit, make sure
that no substance other than the specifi ed refrigerant (R410A)
enters the refrigerant circuit.
• Any presence of foreign substance such as air can cause abnormal pressure rise and may result in explosion or injury.
• The use of any refrigerant other than that specifi ed for the system
will cause mechanical failure, system malfunction, or unit breakdown. In the worst case, this could lead to a serious impediment
to securing product safety.
Meanings of symbols used in this manual
: Be sure not to do.
: Be sure to follow the instruction.
: Never insert your fi nger or stick, etc.
:
Never step onto the indoor/outdoor unit and do not put anything on them.

This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play
with the appliance.
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.

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.
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.
