Service Air Piping; Coupling Alignment Check; Coolant Fluid Level Check; Motor Rotation Direction Check - Sullair 32 250L Series Operator's Manual

Section 3
INSTALLATION
Do not install a water-cooled or an air-cooled/after-
cooled machine where it will be exposed to temper-
atures less than 32˚F.

3.3 SERVICE AIR PIPING

Service air piping should be installed as shown in
Fig. 3-1. A shut-off valve should be installed to iso-
late a machine from the service line if required. Also
notice that the service line should be equipped with
water legs and condensate drains throughout the
system.

3.4 COUPLING ALIGNMENT CHECK

In preparation for the factory test, the coupling sup-
plied with your machine is properly aligned for op-
eration. However, due to shipping and handling, it
is necessary to re-check the coupling alignment.
Refer to coupling alignment procedure explained
in the maintenance section of this manual.

3.5 COOLANT FLUID LEVEL CHECK

This 24KT air compressor is also supplied with the
proper amount of 24KT coolant fluid. However, it is
necessary to check the fluid level at installation.
The level is checked by looking at the sight glass
located on the sump if the sump is properly filled,
the coolant level should fall between the FULL and
ADD marks on the side of the sight glass.

3.6 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-stop button
on the instrument panel. When looking at the motor
from the end opposite the compressor unit, the
shaft should be turning clockwise. If your motor
shaft is not turning clockwise, disconnect the pow-
12
er to the starter and exchange any two of the three
power input leads, then re-check rotation.

3.7 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-
vided 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.
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 machine
was wired for.
2. Check starter and overload heater sizes. (See
strument panel and electrical parts
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
button 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 ex-
plained in Section 3.6.
