4.5 MOTOR ROTATION DIRECTION CHECK
After the electrical wiring has been done, it is nec-
essary to check the direction of motor rotation.
When looking at the motor from the cooler end of
the compressor unit, the cooler fan should be turn-
ing clockwise. If the motor is not turning clockwise,
disconnect power to the starter and exchange any
two of the three power input leads, then check rota-
tion.
A direction of rotation decal is located on the motor
shroud, next to the cooler to insure correct
motor/compressor rotation.
4.6 ELECTRICAL PREPARATION
Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should be
done by a qualified electrician in compliance with
OSHA, National Electrical Code, and any other
applicable State, Federal and local electrical codes
concerning isolation switches, fused disconnects,
etc. Sullair provides a wiring diagram for use by the
installer.
A few electrical checks should be made to help
assure that the first start-up will be trouble-free.
Lethal shock hazard inside. Disconnect all power
at source before opening or servicing.
1. Check incoming voltage. Be sure that compres-
sor is wired for the correct incoming voltage.
2. Check starter for correct size, proper overload
relay and heaters.
3. Check all electrical connections for tightness.
