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 se-
curely 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 con-
troller, 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 (R32/
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.
This appliance is not intended for use by persons (includ-
ing children) with reduced physical, sensory or mental ca-
pabilities, 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 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.

: 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

(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 installation manual.
• Refer to installation manual.
This appliance is intended to be used by expert or trained
users in shops, in light industry and on farms, or for com-
mercial use by laypersons.
