3-4-1. Wiring Instructions
General Precautions on Wiring
(1) Before wiring, confirm the rated voltage of the unit as
shown in the 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 hazard due to insulation failure, the
unit must be grounded.
(4) Each wiring connection must be done tightly and in accor-
dance with the wiring system diagram. Wrong wiring may
cause the unit to misoperate or become damaged.
(5) Do not allowed wiring to touch the refrigerant tubing, com-
pressor, 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.

WARNING
To avoid the risk of fire hazard, be sure
to consult your local dealer if additional
wire length is required. A minimum wire
thickness (gauge) is required, depending
on the length used.
WARNING
!
Since one end of the power connector has
been connected to the unit, when testing
the unit with power supplied, be aware that
the exposed end of the cable will carry a
dangerous electrical charge. Before apply-
ing power, be sure to insulate the exposed
end with electrician’s tape to prevent short
circuit or electrical shock.
!
Loose wiring may cause the terminal to
overheat or result in unit malfunction. A fire
hazard may also exist. Therefore, be sure
that all wiring is tightly connected.
