3. Disconnect pressure transmitter and high temperature switch. Remove lubricant and scavenging
line (steel tubes) from the fittings at the top of the reservoir cover plate. Disconnect air discharge
plumbing at check valve. Carefully remove, deflect and tie the free ends of all remaining tubing
away from reservoir flange without causing permanent set or deformation.
4. Take out cap screws which secure flange to reservoir. Lift cover off and place out of way.
5. Lift out lubricant separator elements and clean gasket sealing surfaces and tank internal
surfaces, as required, to remove residual material.
6. Insert new lubricant separator elements and reassemble by reversing the above removal
procedure. Ensure lubricant separators are centered in the reservoir access hole (not centered on
bolts). Be sure to use new gaskets with metal staples in each. The purpose of the staple is to
ground the separator element to prevent electrostatic buildup.
7. Inspect bolts for proper thread engagement. A short bolt can be identified as a bolt having less
than one bolt diameter worth of thread engagement. A long bolt will bottom out without providing
proper clamping force. Tighten all bolts by hand prior to using a wrench.
8. Tighten bolts evenly by proceeding around reservoir cover multiple times, using a cross pattern
and not exceeding 1/6 turn (1 Flat) per bolt. This ensures even compression of gasket for proper
sealing.
9. Reinstall scavenging tubes.
10. Check separator element to flange for electrical continuity with the tank and lid with an ohm
meter. If continuity is not registered on the meter, disassemble and inspect the metal staples on
the gaskets. Replace the gaskets, if necessary.
