WARNING
• Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electric shock, or fire.
• Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the
terminal block.) Doing so may cause electric shock or fire.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
CAUTION
Recommend stranded cable for interunit wiring. Local code always supersedes recommendation.
• For stranded wires, make sure to use the round crimp-style terminal for connection to the power supply terminal block. Place
the round crimp-style terminals on the wires up to the covered part and secure in place.
• If solid core wire must be used, be sure to curl the end of the lead. Improper work
may cause heat and fire.
