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 hazards due to insulation failure,
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.
