panel of the unit. Refer to this nameplate to choose the right cable, fuse, or switch.
Wiring the Indoor Unit (see diagram on next page)
1. Prepare the cable for connection:
• Using wire strippers, strip the jacket from both ends of the cable to reveal about 6" of the
wires.

• Using a wire crimper, crimp u-lugs to the ends of the wires.
2. Open the control box lid of the indoor unit and locate the wiring diagram on the inside.

each wire to its corresponding terminal.
