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 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 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:
G The remote control wiring and the inter-unit control wiring
should be wired apart from the inter-unit power wiring.
G 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 damaged, it
must be replaced by a repair shop appointed by the
manufacturer, because special purpose tools are
required.
