MAINTENANCE

6.1 MAINTENANCE INTRODUCTION
The Supervisor II monitors the status of the air filter,
fluid filter, and separator elements. When mainte-
nance to these devices is required, the Supervisor
II will display the appropriate maintenance mes-
sage and flash the location LED on the graphics
map as a visual reminder.
DO NOT remove caps, plugs, and/or other compo-
nents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pressure
before doing so.
6.2 DAILY OPERATION
Following a routine start, observe the various
Supervisor II 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 tempera-
tures, etc.).
During the initial start-up or servicing of the pack-
age, fluid may have to be added to the sump ves-
sel to restore an adequate level. Frequent fluid
additions to maintain said level would be indicative
of excessive fluid consumption, and should be
investigated - 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 accumulated
during compressor assembly. Perform the following
maintenance operations to prevent unnecessary
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 AS REQUIRED BY LUBRICA-
TION GUIDE (SECTION 3)
1. Drain the sump and change the compressor fluid.
2. Replace the main fluid filter element.
3. Clean the return line strainers and orifices.
4. Clean or replace the control line filter element.
6.5 FLUID CHANGE
Standard models are filled with Sullube. Sullube
should be changed under the following conditions,
whichever occur first:
1. Every 1800 hours.
2. Once a year.
3. As indicated by fluid analysis.
A fluid sample at every 1000 hours is recommend-
ed. For a free Sullube analysis, send fluid to:
Dow Chemical
Lubricant Technology Center
Building B-1605
Freeport, TX 77541
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
FLUID FILTER MAINTENANCE
Refer to Figure 6-1 . The fluid filter (P/N 02250111-
592) is located schematically between the thermal
valve on the sump and the oil stop valve on the
compressor-mounting bracket. When servicing this
filter, shut the compressor down, make sure all
pressure has been released, then follow the
instructions below. For element replacement order
kit number 250031-850.
To minimize the possibility of filter element rup-
ture, it is important that ONLY replacement ele-
ments identified with the Sullair name, logo and
appropriate part numbers be used, and that sub-
stitute elements NOT be used, due to the fact that
such filters may have inadequate or questionable
working pressure ratings.
1. Unthread the filter canister from the head. A hex
nut is supplied on the bottom of the canister
along with the bottom portion of the canister has
a rough textured surface. Either can be used to
assist in removal of the canister.
2. Pull the canister away from the filter head. The
filter elements will be attached to the filter head.
3. Separate the element from the filter head.
4. Remove the canister seal.
5. Thoroughly clean the filter head and canister in
solvent.
