3-6. Wiring Instructions
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 cir- cuit breaker 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.
