Using oil separator elements at excessive pressure differential can cause
damage to equipment. Replace the elements when the "Change Separator"
advisory appears.
A sudden drop to zero pressure differential or sudden heavy oil carryover may
indicate a ruptured element.
Oil Coalescing Element Service –
Use the following procedures to replace or inspect the element:
1.
Be sure the unit is completely off and that oil pressure is depressurized.
2.
Disconnect, lockout and tagout power supply to the compressor package.
3.
Remove screws holding the top plate to the oil separator vessel and lift the top plate away.
4.
Lift each element from the reservoir.
5.
Inspect and/or replace each element if necessary - shine a light inside each element to reveal areas
of heavy dirt, varnish deposits or breaks (ruptures) in its media.
6.
Inspect the (sealing) o-ring for damage. Before installing new or old element, apply (heavy) grease
to sealing o-ring. Oil may be wiped off by the chamfer and the o-ring could be damaged.
7.
Wipe the cover seal o-ring clean and inspect for damage. Replace if necessary.
8.
Lower elements into reservoir and center on the chamfer. Press elements down into reservoir. Do
not use excessive force as element damage may occur while centering it.
9.
Carefully place cover and o-ring seal on the reservoir flange. Check that the adjustable spacer (e.g.,
pipe segment threaded under cover) does not contact the top of the elements and prevent the cover
from seating flush against the matching separator-housing flange. Install and tighten all cap screws.
10. After compressor is started and pressurized, inspect cover-to-reservoir joint for leaks.
