 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) 

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 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.

WARNING

(Risk of fi re)

This unit uses a fl ammable refrigerant.

If refrigerant leaks and comes in contact with fi re or heating part, it will create harmful gas and there is risk of fi re.

Read the OPERATING INSTRUCTIONS carefully before operation.

Service personnel are required to carefully read the OPERATING INSTRUCTIONS and INSTALLATION MANUAL before operation.

Further information is available in the OPERATING INSTRUCTIONS, INSTALLATION MANUAL, and the like.
