MAINTENANCE

7.1 GENERAL
As you proceed in reading this section, it will be
easy to see that Maintenance Program for the air
compressor is quite minimal. The Supervisor
Controller monitors the status of the air filter, fluid fil-
ter, and separator elements. When maintenance to
these devices is required, the Supervisor will dis-
play the appropriate maintenance message.
7.2 DAILY OPERATION
Prior to starting the compressor, it is necessary to
check the fluid level in the sump. Should the level
be low, simply add the necessary amount. If the
addition of fluid becomes too frequent, a simple
problem has developed which is causing this
excessive loss. See the Troubleshooting Section
under Excessive Fluid Consumption for a probable
cause and remedy.
Following a routine start, observe the various
Supervisor Controller displays to check that normal
readings are being made - previous records are
very helpful in determining the normalcy of the
measurements. These observations should be
made during all expected modes of operation (i.e.
full load, no-load, different line pressures, cooling
water temperatures, etc.).
Frequent fluid additions to maintain said level would
be indicative of excessive fluid consumption, and
should be investigated - see the Troubleshooting
Section 8 of this manual for probable cause and
remedy.
7.3 MAINTENANCE AFTER INITIAL 50 HOURS OF
OPERATION
After the initial 50 hours of operation, a few mainte-
nance requirements are needed to rid the system of
any foreign materials. Perform the following mainte-
nance operations to prevent unnecessary prob-
lems.
1. Clean the return line strainers.
2. Clean the return line orifices.
7.4 MAINTENANCE EVERY 1000 HOURS OF OPER-
ATION
1. Clean the return line strainers.
2. Change the fluid filter element.
7.5 MOTOR BEARINGS
Grease motor per manufacturer’s recommenda-
tions.
7.6 FLUID MAINTENANCE
Drain the sump and change the compressor fluid
per recommendations in Section 3, Specifications.
Standard models are filled with Sullube. Sullube
Figure 7-1 Air Filter (P/N 02250135-154)
*Replacement Element P/N 02250135-155
DO NOT remove caps, plugs, and/or other com-
ponents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pressure
before doing so.
During the initial start-up or servicing of the
package, fluid may have to be added to the sump
vessel to restore an adequate level.
