• 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 (R32) 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 (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.

In case of an abnormal condition (such as a burning smell), stop the air conditioner and discon-
nect 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, stop operations and ventilate the room well and consult your
dealer immediately. If a repair involves 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.
