altered, or repaired by the user.

• An improperly handled air conditioner may cause fi re, electric
shock, injury, or water leakage, etc. Consult your dealer.

• If the power supply cord is damaged, it must be replaced by the
manufacturer or its service agent in order to avoid a hazard.

When installing, relocating, or servicing the unit, make sure
that no substance other than the specifi ed refrigerant (R410A)
enters the refrigerant circuit.

Any presence of foreign substance such as air can cause abnormal

•
pressure rise and may result in explosion or injury.

• The use of any refrigerant other than that specifi ed for the system
will cause mechanical failure, system malfunction, or unit break­down. In the worst case, this could lead to a serious impediment
to securing product safety.
