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 circuit 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.
