Motor Rotation Direction Check - Sullair ES-6 Series User Manual

ES-6 USER MANUAL
WARNING
Assure that line pressure guage on com-
pressor indicates "ZERO" pressure before
any work is done. Failure to omply may
cause injury.
When the compressor fluid is ready to be changed,
the compressor needs to be shutdown with the
power to the compressor disconnected (see Warning
above). Drain the fluid from the compressor using the
compressor fluid drain cap (See Figure 2-1).
Fluid capacity for the compressor can be found in
Section 3: Specifications of this manual. The
compressor sump is properly filled when the level on
the fluid level sight glass is 3/4 of the sight tube.
During operation, the fluid level should cover 1/4 to 1/
2 of the sight glass. DO NOT OVERFILL.

4.5 MOTOR ROTATION
DIRECTION CHECK
After the electrical wiring has been done, it is
necessary to check the direction of motor rotation.
This can be done by jogging the START selector
switch on the front of control center. When looking at
the motor from the cooler end of the compressor unit,
the cooler fan should be turning 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 rotation.
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.
