burner, a heater or a cooker may result in a harmful gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer where you purchased the
unit.
Do not use the air conditioner until a service person confirms
that the portion where the refrigerant leaks is repaired.
Do not use the air conditioner for other purposes.
In order to avoid any quality deterioration, do not use the unit
for cooling precision instruments, food, plants, animals or
works of art.
Before cleaning, be sure to stop the operation, turn the
breaker off or pull out the supply cord.
Otherwise, an electric shock and injury may result.
In order to avoid electric shock or fire, make sure that an
earth leak detector is installed.
Be sure the air conditioner is grounded.
In order to avoid electric shock, make sure that the unit is
grounded and that the earth wire is not connected to gas or
water pipe, lightning conductor or telephone earth wire.
