be properly grounded for operation.
Torque the capscrews to 85 to 90 ft.-lbs. (115 to
122 Nm).
DO NOT
over-tighten, as damage to
the separator element can result.
A continuity check is critical to perform when
replacing separator elements.
Check continuity between the separator and the
retaining ring, along with the separator element
and tank body.
6. Next, install the tank flange gasket that is provid-
ed. Reinstall the tank lid. Install the capscrews
finger- tight, then gradually tighten in a criss-
cross pattern in 4 to 5 steps. Always tighten the
capscrews alternately at opposite sides of the
cover. Lubricate the capscrews with compressor
fluid, and torque to 200 ft.-lbs. (271Nm).
7. Clean or replace fluid return line strainer.
8. Clean the fluid return line orifice installed in the
side of the compressor unit air end.
OIL RETURN/SIGHT GLASS MAINTENANCE
. The oil return/sight glass sub-
assembly is attached to the separator tank. 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 Section
of this manual. The maintenance on an oil
return/sight glass is mainly concerned with the con-
dition of the filter assembly. Order filter assembly
no. 02250117-782, and use the following instruc-
tions 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.
