ELECTRICAL WIRING
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 accor-
dance 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, 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 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.
(10) All wiring must be used class 1.
