Fuses and Circuit Breakers
The interrupting rating of fuses and circuit
breakers is to be determined based on the
KAIC rating of the unit. Refer to the wiring
diagram for fuse sizing.
Table 16 – 35 KAIC Fuse Sizing
Table 17 – 65 KAIC Fuse Sizing
Startup
(See back of the manual for startup form.)
Before startup of the condenser or condensing
unit, make sure that the following items have
been checked.
1. Verify that electrical power is available to
the unit.
2. Verify that any remote stop/start device
connected to the unit controller is
requesting the unit to start.
Cycle through all the compressors to confirm
that all are operating within tolerance.
While performing the check, use the startup
form to record observations of amps and
refrigerant pressures.

3-PHASE ROTATION
Rotation must be checked on all
MOTORS AND COMPRESSORS of
three phase units. Condenser fan
motors must all be checked by a
qualified service technician at startup
and any wiring alteration must only be
made at the unit power connection.
Variable frequency drives are
programmed to automatically rotate
the fan in the correct rotation. Do not
rely on fans with variable frequency
drives for compressor rotation.
ELECTRIC SHOCK
Electric shock hazard. Shut off all
electrical power to the unit to avoid
shock hazard or injury from rotating
parts.
QUALIFIED INSTALLER
Improper installation, adjustment,
alteration, service or maintenance can
cause property damage, personal
injury or loss of life. Startup and
service must be performed by a
Factory Trained Service Technician.
