3-6. Wiring Instructions
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, with a power supply disconnect and cir-
cuit breaker for overcurrent protection provided in
the exclusive line.
(3) To prevent possible hazard due to insulation fail-
ure, the unit must be grounded.
(4) Each wiring connection must be done tightly and 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.
