5. Wiring Instructions

5-1. General Precautions on Wiring

(1) Before wiring, confirm the rated voltage of the unit as

shown on its nameplate, then carry out the wiring

closely following the wiring diagram.

(2) Provide a power outlet to be used exclusively for each

unit, with a power supply disconnect and circuit break-

er for overcurrent protection provided in the exclusive

line.

(3) To prevent possible hazard due to insulation failure,

the unit must be grounded.

(4) Each wiring connection must be done tightly and in

accordance with the wiring system diagram. Wrong

wiring may cause the unit to misoperate or become

damaged.

(5) Do not allow wiring to touch the refrigerant tubing,

compressor, or any moving parts of the fan.

(6) Unauthorized changes in the internal wiring can be

very dangerous. The manufacturer will accept no

responsibility for any damage or misoperation that

occurs as a result of such unauthorized changes.

5-2. Recommended Wire Length and Diameter

Regulations on wiring diameter differ from locality to locality.

For field wiring requirements, please refer to your local elec-

trical codes. Carefully observe these regulations when car-

rying out the installation.

Table 6 shows maximum wire lengths for control line and

power line and fuse or circuit capacity.

Refer to the wiring system diagram (Fig. 25a or 25b) for the

meaning of (A), (B), and (C) in Table 6.
