Electrical Wiring
General Precautions on Wiring
(1) Before wiring, con
fi
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, 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 damaged,
it must be replaced by a repair shop appointed by
the manufacture, because special-purpose tools are
required.
