Pressure Differential Gauging - The “CHANGE SEPARATOR” advisory will flash when the pressure
differential across the oil separator reaches approximately 8 psid (.55 bar). Replace the oil separator
element at this time. If ignored, the unit will shut down and the advisory will illuminate steadily when the
pressure differential reaches 15 psid (1 bar).
Using an oil separator element at excessive pressure differential can cause
damage to equipment. Replace the separator when the "Change Separator"
advisory appears.
NOTICE
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. Disconnect oil return to compressor tubing at tube elbow near the discharge manifold flange on
the top plate.
4. Loosen the nut on fitting at manifold flange and completely withdraw the tubing through the
fitting.
5. Disconnect all other tubing from discharge manifold.
6. Disconnect discharge manifold pipe union.
