Using an oil separator element at excessive pressure differential can cause
damage to equipment. Replace the separator when the "Change Separator"
advisory appears.
A sudden drop of zero pressure differential or sudden heavy oil carryover may
indicate a ruptured element.
Inspection - After removal of separator element, shine a light inside the element to reveal areas of heavy
dirt or varnish deposits or breaks (ruptures) in the element media.
Removal Of Oil Separator For Inspection Or Replacement:
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
1. Be certain unit is completely off and that no air pressure is in the oil reservoir.
2. Disconnect, lockout and tagout power supply to the starter.
3. Remove screws holding the top plate to the separator housing. Lift the top plate from the
separator housing.
4. Lift the separator from the separator housing.
5. Inspect and/or replace the separator as necessary. Be sure the o-ring is not damaged. Before
installing (or reinstalling) any separator apply grease to the o-ring. Oil will be wiped off by the
chamfer and the o-ring could be damaged.
6. Remove any gasket material adhering to top plate or separator housing, and install new gasket.
7. Lower the separator into the housing and center the separator on the chamfer. Press separator
down into the housing. Do not use excessive force as separator damage can occur.
8. Place the spacer on the indent in the separator. Seat the top plate to the separator, spacer and
separator housing. Install and tighten all cap screws.
9. Run the unit and check for leaks.
