WARNING

CAUTION

Only a dealer or qualified technician should 
perform installation.

Properly install all parts according to the 
instructions in the Installation Manual.

After installation, check for a refrigerant leak.

Do not make any modifications or alterations.
Consult your dealer for repair.

When installing or relocating the unit, check that 
no substance other than the specified refrigerant 
(R410A) enters the refrigerant circuit.

Do not touch the refrigerant pipes and refrigerant 
circuit components with bare hands during and 
immediately after operation.

In the event of a refrigerant leak, thoroughly 
ventilate the room.

s

 Improper installation may result in refrigerant gas leakage and 

equipment damage.

s

 If the wrong twinning pipe or wrong size connecting pipe is used, 

air conditioning performance will suffer.

s

 If leaked refrigerant comes in contact with a heat source, such 

as a fan heater, stove, or electric grill, toxic gases will be  
generated.

s

 Improper installation may result in water leakage, electric shock, 

or fire.

s

 Any presence of foreign substance or air can cause abnormal 

pressure rise or explosion.

s

 During or immediately after operation, certain parts of the unit 

such as pipes and compressor may be either very cold or hot, 
depending on the state of the refrigerant in the unit at the time. 
To reduce the risk of frostbites and burns, do not touch these 
parts with bare hands.

s

 If refrigerant leaks and comes in contact with an open flame, 

toxic gases will be generated.

Properly dispose of packing materials.

s

 Plastic bags can pose suffocation and choking hazards: keep 

them out of the reach of children. Tear the plastics bags before 
disposing of them.
