Motor Rotation Direction Check; Electrical Preparation - Sullair 10B Series Operator's Manual

4.6 MOTOR ROTATION DIRECTION CHECK

After the electrical wiring has been done, it is nec-
essary to check the direction of the motor rotation.
This can be done by jogging the START and STOP
buttons on the control box door. When looking at
the motor from the end opposite the compressor
unit, the shaft should be turning clockwise. If the
motor shaft is not turning clockwise, disconnect
the power to the starter and exchange any two of
the three power input leads, then re---check rota-
tion. A "Direction of Rotation" decal is located on
the adapter between the motor and compressor to
show proper motor/compressor rotation.

4.7 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 any other
applicable local electrical code concerning isola-
tion switches, fused disconnects, etc. Sullair pro-
vides a wiring diagram for use by the installer.
An electrical check should be made to help assure
that the first start ---up will be trouble free.
Section 4
INSTALLATION
DANGER
!
Lethal shock hazard inside.
Disconnect all power at source, before opening
or servicing.
1. Check incoming voltage. Be sure that the incom-
ing voltage is the same voltage that the com-
pressor was wired for.
2. Check starter and overload heater sizes (see
control box assembly in Section 7, Parts Manu-
al).
3. Check all electrical connections for tightness.
4. "DRY RUN" the electrical controls by discon-
necting the three (3) motor leads from the
starter. Energize the control circuits by pushing
the START button and check 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 Section 4.6.
