3-1. 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 cir-
cuit 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, 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 dam-
aged, it must be replaced by a repair shop
appointed by the manufacture, because special
purpose tools are required.
