Repairing Refrigerant Leaks
 WARNING
•  If the refrigerant leaks, turn o the air 
conditioner and any combustible heating 
devices, ventilate the room and call your 
dealer immediately. Refrigerant is both toxic 
and flammable. 
DO NOT
 use the air 
conditioner until the leak is repaired.
 
•  When the air conditioner is installed in a 
small room, measures must be taken to 
prevent the refrigerant concentration from 
exceeding the safety limit in the event of 
refrigerant leakage. Concentrated 
refrigerant causes a severe health and safety 
threat.    
Refrigerant Leak Detection System 
(some models)
•  In the event of a refrigerant leak, the LCD 
screen will display “EC” and the LED indicator 
light will flash.
