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. A power supply disconnect and circuit breaker for overcurrent protection should be provided in the exclusive line.

(3)To prevent possible hazards from insulation failure, the unit must be grounded.

(4)All wiring must be connected tightly.

(5)Do not allow wiring to touch refrigerant tubing, compressor, or any moving parts of the fan.

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.

(1)Insert the inter-unit wiring (according to local electrical codes) into the through-the-wall PVC pipe. Run the wiring toward the indoor side allowing approx. 10 inches to extend from the wall face. (Fig. 1-43)

(2)Route the inter-unit wiring from the back of the indoor unit and pull it toward the front for connection. (Figs. 1-44a and 1-44b)

(3)Connect the inter-unit wiring to the corresponding terminals on the terminal plate (Figs. 1-44a and 1-44b) while referring to the wiring diagram.
