Repairing Refrigerant Leaks

WARNING
• If the refrigerant leaks, turn off 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.
