8. INSTALLATION INSTRUCTIONS
3) 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 exclu-
sively for each unit, and a power supply
disconnect and circuit breaker for
overcurrent protection should be pro-
vided in the exclusive line.
(3) To prevent possible hazards from insula-
tion failure, the unit must be grounded.
(4) Each wiring connection must be done in
accordance with the wiring system dia-
gram. Wrong wiring may cause the unit
to misoperate or become damaged.
(5) Do not allow wiring to touch the refriger-
ant tubing, compressor, or any moving
parts of the fan.
(6) Unauthorized changes in the internal
wiring can be very dangerous. The manu-
facturer 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 ELECTRI-
CAL CODES before beginning. You must
ensure that installation complies with all
relevant rules and regulations.
(8) To prevent malfunction of the air condi-
tioner caused by electrical noise, care
must be taken when wiring as follows:
The inter-unit control wiring and the remote
control wiring (option) should be wired
apart from the inter-unit power wiring.
It is recommended that shielding wires or
twisted pair wires be used for the remote
control and the inter-unit control wiring if
the air conditioner is installed where it is
exposed to the influence of electrical and/
or electro-magnetic noise.
