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 element media.
Removal of Oil Separator For Inspection or Replacement :
DANGER
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.
DANGER
Compressor, air/oil reservoir, separation chamber and all piping and tubing
may be at high temperature during and after operation.
1. Be certain the unit is off and that no air pressure is in the oil reservoir. The compressor package will
automatically blowdown in about 2 minutes.
2. Close the air service valve located after the compressor package discharge.
3. Disconnect, lockout and tagout the power supply to the starter.
4. Remove the minimum pressure/check valve (air/oil separator housing) cover.
5. Lift out the air/oil separator elements. See Item 1, Figure 5-1, page 24.
6. Inspect and/or replace the separator as necessary.
7. Clean the sealing surfaces on the air/oil separator and the minimum pressure/check valve.
8. Clean the orifice, Item 3, Figure 5-1, page 24, in the oil return line, the strainer in the oil return line,
and if necessary, the air/oil separator housing.
9. Grease the O-Ring on the separator element and install the separator into the housing.
10. Replace the O-Ring between the minimum pressure/check valve and the air/oil separator housing.
11. Replace the sealing kit in the minimum pressure/check valve. After the assembling of the valve,
leave about .08 inch gap between the nut and the cover of the valve. See “Changing Minimum
Pressure/Check Valve Seals,” Section 4, page 21.
12. Install the minimum pressure/check valve assembly and tighten the bolts alternately for even
tightness.
