4.4 COUPLING ALIGNMENT
CHECK
No coupling alignment is required.
4.5 FLUID LEVEL CHECK
The air compressor is shipped with the proper
amount of fluid installed. However, it is necessary to
check the fluid level at the time of installation and
during continued operation of the compressor. The
fluid level is to be checked when the compressor is in
the SHUT DOWN MODE (fluid level may not be
visible when operating), and by looking at the sight
glass on the separator/sump tank. To be able to see
the fluid level it may be necessary to start the
machine and build the separator/sump tank pressure
up to 10/20 psi and then shut down. If no fluid level is
seen in the sight glass add fluid to the center of the
glass. Do not overfill in any case. When a complete
fluid change is performed, fill the separator/sump
tank to the maximum allowable fluid level (up to the
fill plug.)
4.6 ELECTRICAL PREPARATION
Interior electrical wiring is performed at the factory.
Required customer wiring should be done by a
qualified electrician in compliance with OSHA,
National Electrical Code, and/or any other applicable
state, federal and local electrical codes concerning
isolation switches, fused disconnects, etc.
• The compressor and drive should be pro-
vided with a proper grounding conductor/
earthed in accordance with both local and
National Electrical Code (NEC) require-
ments.
• Installation of this compressor must be in
accordance with recognized electrical
codes and any local Health and Safety
Codes.
• Feeder cables should be sized by the cus-
tomer/ electrical contractor to ensure that
the electrical circuit the system is con-
nected to is balanced and not overloaded
by any other electrical equipment. The
length of wiring from a suitable electrical
feed point is critical as voltage drop may
impair the performance of the compressor.
Cable sizes may vary so the mains termi-
nals will accept from 8 ga. to 3/0 ga. cable.
• Feeder cable connections to incoming ter-
minals L1- L2-L3 should be tight and clean.
The applied voltage must be compatible with the
motor and compressor data plate ratings.
• A starter hole is provided for incoming
power connection. If it is necessary to
make a hole in the control box in a different
location, care should be taken to not allow
metal shavings to enter the starter and
other electrical components. If another hole
is used, the original hole must be blocked
off with a suitable knockout seal.
CAUTION
The use of plastic bowls on line filters and
other plastic airline components without
metal guards can be hazardous. Synthetic
coolants or the additives used in mineral
oils can alter their structural integrity and
create hazardous conditions. Metal bowls
should be used on any pressurized system
for safety concerns.
"The Plastic Pipe Institute recommends
against the use of thermoplastic pipe to
transport compressed air or other com-
pressed gases in exposed above ground
locations, e.g. in exposed plant piping." (I)
Sullube should not be used with PVC piping
systems. It may affect the bond at cemented
joints. Certain other plastic materials may
also be affected.
(I) Plastic Pipe Institute, Recommendation
B, Adopted January 19, 1972.
NOTE
Customer must provide electrical supply
power disconnect within sight of
machine. The fuse protecting the circuit
and the compressor must be selected in
accordance with the data provided inside
the starter enclosure.
