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
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
assure that the first start-up will be trouble free.
Lethal shock hazard inside. Disconnect all power
at source before opening or servicing.
INSTALLATION
1. Check incoming voltage. Be sure that the incom-
ing voltage is the same voltage that the com-
pressor was wired for. Verify that control trans-
former primary is wired for correct line voltage.
2. Check starter and overload heater sizes (see
Electrical Controls Section 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.
Energize the control circuits by pushing the
(START) pad and check all protective devices
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
explained in Section 4.6.
