PRECAUTIONS FOR RELOCATION OR REPAIRS

 WARNING

x

Do not perform any repairs or modifications by yourself. Consult the dealer if the 
unit requires repair.

If you repair or modify the unit, it can cause water leaks, electric shocks or fire.

x

Consult your dealer for repairs.

Wrong repairs could cause an electric 
shock, fire, etc.

x

In case the air-conditioner is relocated 
elsewhere, contact your dealer or a 
qualified installer.

Faulty installation may cause water 
leakage, electric shock, fire, etc.

x

If you notice anything abnormal (smell 
of burning, etc.), stop the system, turn 
off the power source and consult your 
dealer.

Continued use of the system in 
abnormal circumstances can result in 
malfunctioning, electric shock, fire, etc.

x

If the air-conditioner fails to cool 
or warm the room, it may have a 
refrigerant leakage. Contact your 
dealer.
If refrigerant needs to be added, 
check with your dealer for proper 
instructions.

If the refrigerant comes in contact with the 
bare skin, it may cause cold injury.
If the refrigerant gas is inhaled 
excessively, it may cause deterioration 
of nerve function like dizziness and 
headache, or deterioration of heart 
function like irregular heartbeat and heart 
palpitation temporarily.  If refrigerant 
unexpectedly leaks from the unit onto 
a fan heater, stove, hotplate or other 
heat source, harmful gases could be 
generated.
