MACHINES ONLY.
Your fluid filter includes a proprietary replaceable
element available solely from Sullair and its agents
- DO NOT substitute.
1. Using a strap wrench, remove the old element
and gasket.
2. Clean the gasket seating surfaces.
3. Apply a light film of fresh fluid to the new gasket
and hand tighten new element until gasket con-
tacts the seat.
4. Continue tightening element an additional 1/2 to
3/4 turn.
5. Restart package and check for leaks.

SEPARATOR ELEMENT MAINTENANCE

Refer to Figure 7-3. The Supervisor indicates when
the separator elements should be serviced (this
happens when the pressure drop across the ele-
ments has exceeded 10 psig [0.7 bar]), or once a
year, whichever occurs first. Element service can
be provided as follows:
Relieve all pressure from the sump tank and all
compressor lines.
1. Disconnect all pipe work connected to the sump
cover.
2. Loosen and remove the twelve (12) hex head
capscrews (3/4" x 3") from the cover plate.
3. Using the lift handles, lift the cover plate from the
sump.
4. Remove the two (2) nested separator elements.
5. Scrape the old gasket material from the cover
and sump flange - avoid dropping any scraps
into the sump.
6. Inspect the sump vessel for rust, dirt, etc.
8. Reinsert the separator element, with gasket
attached, into the sump, taking care not to dent
the former against the tank opening.
DO NOT remove grounding staples from the gas-
kets. DO NOT use any type of gasket eliminator.

OIL RETURN/SIGHT GLASS MAINTENANCE

Refer to Figure 7-4. The oil return/sight glass sub-
assembly is attached to the separator tank lid. Oil
return/sight glass maintenance should be per-
formed on a routine basis parallel to that of the fluid
filter, or as indicated in the troubleshooting sections
of this and the Supervisor Controller manuals. The
maintenance on an oil return/sight glass is mainly
concerned with the condition of the filter assembly.
Order filter assembly no. 02250117-782, and use
the following instructions as a guide.
Always performing maintenance on both oil
return/sight glasses at the same time.
1. Disconnect the tubes at the tops of the sight
glass assemblies.
2. Unscrew male connector (for left-side glass), or
the straight thread tube connector (for right-side
glass) from sight glass/orifice blocks.
3. Remove used filter assembly, and replace with
new assembly.
4. Coat/lubricate the o-rings will silicone grease.
5. Reattach the connectors to the sight glass/orifice
blocks.

PRESSURE REGULATOR ADJUSTMENT

Start the compressor and adjust the service valve to
maintain service air pressure approximately at five
