ELEMENT INSPECTION
1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light will
shine through the element, revealing any holes.
2. Inspect all gaskets and gasket contact surfaces
of the housing. Should faulty gaskets be evident,
correct the condition immediately.
3. If the clean element is to be stored for later use,
it must be stored in a clean, closed container.
4. After the element has been installed, inspect and
tighten, if necessary, all air inlet connections
prior to resuming operation.
SEPARATOR ELEMENTS REPLACEMENT
Refer to Figure 7-3 . The separator elements must
be changed when “Separator Maintenance
Required” message is displayed, or once a year
whichever occurs first. Follow the procedure
explained below for separator element replace-
ment.
PROCEDURE FOR 200-350HP/149-261KW ELE-
MENT REPLACEMENT
1. Relieve all pressure from the separator and all
compressor lines prior to disconnecting any
pipes, tubing, etc.
2. Disconnect all piping connected to the separator
cover to allow removal (return lines, service
lines, etc.).
3. Loosen and remove the twelve (12) 3/4” x 3” hex
head capscrews from the cover plate.
4. Lift the cover plate from the separator using a
3/4” jackscrew under the lifting arm post. The lid
can be pivoted to the side supported by the lift-
ing arm.
5. Remove the primary and secondary separator
elements.
6. Scrape the old gasket material from the cover
and flange on the sump being careful not to let
the scraps fall in the sump.
7. Inspect the separator tank for rust, dirt, etc.
8. Reinsert the separator elements with gaskets
attached into the sump taking care not to dent
them against the tank opening.
DO NOT remove
grounding staples. Check between separator
element flange and tank for continuity after
torquing bolts.
DO NOT use anti-seize com-
pound on gaskets.
9. Clean the underside of the separator tank cover
and remove any rust.
10. Replace the cover plate, washers and 3/4-10
capscrews. Lubricate and Torque to 200 ft.-lbs.
(271 Nm).
11. Reconnect all piping making sure return line
tubes extend to the bottom or 1/4” (6mm) above
the bottom of the separator element. This will
assure proper fluid return flow to the compres-
sor.
12. Check the return line strainers before restarting
the compressor (order replacement kit no.
02250117-782).
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 (both Supervisor and Maintenance) of this
manual. 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.
