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.
Removal of Oil Separator for Inspection or Replacement
:
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 all control lines from the top of the separator housing.
4.
Remove screws holding the top plate to the separator housing. Lift the top plate from the
separator housing using the adjustable jack screw and swivel out of position.
5.
Lift the separator from the separator housing.
6.
Inspect and/or replace the separator as necessary. Be sure the O-rings are not damaged. Before
installing (or reinstalling) any separator apply grease to the O-rings.
7.
Lower the separator into the housing. Do not use excessive force as separator damage can
occur.
8.
Place the spacer on the indent in the separator. Swivel top back into position on top of the
reservoir. Install and tighten all cap screws.
9.
Re-install control lines.
10.
Run the unit and check for leaks.
COMPRESSOR OIL SYSTEM CHECK
- The following readings are based on ambient temperature of
80
F (27
C) for air-cooled oil cooler and 80
F (27
C) inlet water on water-cooled oil cooler, with the
system in good condition. Compressor should be at operating temperature at the time of checks. One-half
hour of loaded operation is usually sufficient to reach level-out operating temperatures.
Air and Oil Discharge Temperature
- 165
F to 195
F (74
C to 91
C) - Read at gauge on the instrument
panel or check with a thermometer at the discharge housing.
Compressor Oil Inlet Temperature
- 150
F to 160
F (66
C to 71
C) - Install a tee at the oil filter outlet
and check with a thermometer.
Oil Inlet Pressure
- Check at the fitting in the line near the compressor oil inlet. With air receiver pressure
at 100 psi (6.9 bar), oil inlet pressure should be 70 psig to 75 psig (4.83 bar to 5.17 bar).
