WARNING
Before performing any electrical or wiring work, turn off the main power to the
system.
The signal cable enables communication between the indoor and outdoor units. You must first
choose the right cable size before preparing it for connection.
USE THE RIGHT CABLE
• Indoor Power Cable (if applicable): H05VV-F or H05V2V2-F
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F
CABLE SIZING
Use a minimum of 16 AWG for power and signal cables connected to and between the indoor and
outdoor units.
Choose the correct size of cable
The size of the power supply cable, signal cable, fuse, and switch needed is determined by the
maximum current of the unit. The maximum current is indicated on the nameplate located on the
side 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.
• Strip the insulation from the ends of the wires.
• Using a wire crimper, crimp u-lugs to the ends of the wires.
2. Rotate the sensor bracket upward then remove the electrical box cover.
3. Unscrew the cable clamp below the terminal block and place it to the side.
4. Refer to the wiring diagram on the control box cover and connect the u-lugs to the terminal
block. Firmly screw the u-lug of each wire to its corresponding terminal.
5. After checking to make sure every connection is secure, use the cable clamp to fasten the
signal cable to the unit. Screw the cable clamp down tightly.
6. Replace the control box lid.
7. Only connect the unit to an individual branch circuit outlet. Do not connect another appliance
to that outlet.
8. Make sure to properly ground the air conditioner.
9. Every wire must be firmly connected. Loose wiring can cause the terminal to overheat,
resulting in product malfunction and possible fire.
10. Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts
within the unit.
11. If the unit has an auxiliary electric heater, it must be installed at least 40" away from any
combustible materials.
12. To avoid getting an electric shock, never touch the electrical components soon after the
power supply has been turned off. After turning off the power, always wait 10 minutes or more
before you touch the electrical components.
