INSTALLATION
Figure 2-1 Service Air Piping (Typical Installation)
2.6 MOTOR ROTATION CHECK
After the electrical installation has been done, it is
necessary to check the direction of motor rotation.
Pull out the EMERGENCY STOP button and press
once, quickly and in succession, the (START) "I"
and (STOP) "O" pads. This action will "bump start"
the motor for a very short time. When looking at the
motor rear end, the driveline should be rotating
counterclockwise. If the reversed rotation is noted,
disconnect the power to the starter and exchange
any two of the three power input leads, then re--
check rotation. A "Direction of Rotation" decal is lo-
cated on the top of the compressor/motor adaptor
piece.
2.7 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/or any other
applicable local electrical codes concerning isola-
tion switches, fuse disconnects, etc. Sullair pro-
vides a wiring diagram for use by the installer.
A few electrical checks should be made to help as-
sure that the first start--up will be trouble free.

DANGER
!
Lethal shock hazard inside.
Disconnect all power at source before opening or
servicing.
NOTE
Customer must provide electrical supply power
disconnect within sight of machine.
1. Check incoming voltage. Be sure that the incom-
ing voltage is the same voltage that the compres-
sor was wired for.
2. Check starter and overload heater sizes (see
electrical parts in Parts Manual).
3. Check all electrical connections for tightness.
4. "DRY RUN" the electrical controls by disconnect-
ing the three (3) motor leads from the starter. En-
ergize the control circuits by pushing the
(START) "I" pad and checking all protective de-
vices to be sure that they will de--energize the
starter coil when activated.
5. Reconnect the three (3) motor leads and jog the
motor for a direction of rotation check, as ex-
plained in
S ec t ion 2.
