The separator elements must be replaced. DO
NOT clean the separator elements.
1. Disconnect all piping connected to the sump
cover to allow removal (return lines, service
lines, etc.).
2. Loosen and remove the eight (8) hex head cap-
screws (5/8 x 2") from the cover plate.
3. Lift the cover plate from the sump.
4. Remove the separator elements.
5. Inspect the receiver/sump tank for rust, dirt, etc.

taking care not to dent them against the tank
opening.

tubes extend to the bottom or 1/4" (6mm) above

insure proper fluid return flow to the compressor.

the compressor.

OIL RETURN/SIGHT GLASS MAINTENANCE

Refer to Figure 8-4. 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 perform 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.
