Gardner Denver AUTO SENTRY EAU99G Operating And Service Manual page 61

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.
A sudden drop of zero pressure differential or sudden heavy oil carryover may
indicate a ruptured element.
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.
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.
