7-2. Recommended Wire Length and Diameter

Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Carefully observe these regulations when carrying out the installation.

NOTE

Refer to the wiring system diagram (Fig. 6).

Refer to your local codes or in the absence of local codes with the National Electric Code: ANSI/NFPA70.

WARNING

Be sure to comply with local codes on running wiring from the outdoor unit to the indoor unit (size of wire and wiring method, etc.).

Each wire must be firmly connected.

No wire should be allowed to touch refrigerant tubing, the compressor, or any moving part.

WARNING

To avoid the risk of electric shock, each air conditioner unit must be grounded.

CAUTION

Be sure to connect the power supply line to the outdoor unit as shown in the wiring diagram. The indoor unit draws its power from the outdoor unit.
