7 Electrical Wiring
7.1 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 provided 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 dia -
gram. 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 manufac -
turer 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-to-Water 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.
● Use shielded wires for remote control wiring between units and ground the
shield on indoor unit’s side.
9. If the power supply cable of this appliance is damaged it must be replaced by a
repair shop appointed by the manufacturer, because special-purpose tools are
required.
