4. ELECTRICAL WIRING
4-1. General Precautions on Wiring
(1) Before wiring, confi rm 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 fi eld wiring rules, must follow 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 one side
only.
(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.
(10) All wiring used must be Class 1.
