MAINTENANCE

6.1 MAINTENANCE INTRODUCTION
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 moni-
tors the status of the air filter, fluid filter, and separa-
tor elements. When maintenance to these devices
is required, the Supervisor will display the appropri-
ate maintenance message and flash the location
LED on the graphics map as a visual reminder.
WARNING
!
DO NOT remove caps, plugs, and/or other com-
ponents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pres-
sure before doing so.
6.2 DAILY OPERATION
Following a routine start, observe the various Su-
pervisor 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 ex-
pected modes of operation (i.e. full load, no---load,
different line pressures, cooling water tempera-
tures, etc.).
During the initial start---up or servicing of the pack-
age, fluid may have to be added to the sump vessel
to restore an adequate level. Frequent fluid addi-
tions to maintain said level would be indicative of
excessive fluid consumption, and should be inves-
tigated --- see the Troubleshooting Section of this
manual for probable cause and remedy.
6.3
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 which may have accumu-
lated during compressor assembly. Perform the fol-
lowing maintenance operations to prevent unnec-
essary problems.
1. Clean the return line strainers.
2. Clean the return line orifices.
3. Change the fluid filter elements.
4. Clean the control line filters.
6.4
MAINTENANCE EVERY 1000
HOURS
After 1000 hours of operation, it will be necessary to
perform the following:
1. Clean the return line strainers.
2. Lubricate the Sullicon Control linkage.
3. Replace the fluid filter element.
6.5 FLUID CHANGE
Standard models are filled with the long life lubri-
cant Sullube.
Sullube should be changed under the following
conditions, whichever occurs first:
1. Every 8000 hours.
2. Once a year.
3. As indicated by fluid analysis.
For compressors filled with 24KT, the fluid needs to
be changed only when indicated by fluid analysis
or if the fluid has been contaminated.
A fluid sample at every 4000 hours is recom-
mended. Return fluid to Sullair Corporation in
Michigan City for free analysis. To facilitate this, a
sample bottle is included with the compressor.
6.6 SEPARATOR MAINTENANCE
Replace the separator elements when the separa-
tor maintenance message is displayed or after one
(1) year, whichever comes first. The separator ele-
ments must be replaced. DO NOT clean the sepa-
rator elements.
6.7 PARTS REPLACEMENT AND ADJUSTMENT
PROCEDURES
MAIN FILTER MAINTENANCE
Refer to Figure 6- - -1 . The main filter (P/N
250007---219) is located schematically between
the compressor cooler and the compressor injec-
tion port. When servicing the main filter, shut the
compressor down, make sure all pressure has
been released, then follow the instructions below.
For element replacement order kit number
250008---956.
