5. ELECTRICAL WIRING

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, and a power supply disconnect and circuit breaker for overcurrent protection should be provid- ed in the exclusive line.

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

(4)Each wiring connection must be done 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.

(7)Regulations on wire diameters differ from locality to locality. For field wiring rules, please refer to your LOCAL ELECTRICAL CODES before beginning. You must ensure that installation complies with all relevant rules and regulations.

(8)To prevent malfunction of the air conditioner caused by electrical noise, care must be taken when wiring as follows:

●The remote control wiring and the inter-unit control wiring should be wired apart from the inter-unit power wiring.

●Use shielded wires for inter-unit control wiring between units and ground the shield on both sides.

(9)If the power supply cord of this appliance is dam- aged, it must be replaced by a repair shop appoint- ed by the manufacture, because special purpose tools are required.
