7. INSTALLATION INSTRUCTIONS
4) 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
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 ELECTRI-
CAL CODES (ex. National Electric Code:
ANSI/NFPA70) 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.
