COLD AMBIENT OPERATION
- See “Installation for Cold Weather Operation,” Section 2.
ADDITION OF OIL BETWEEN CHANGES
must be made when the oil level is in the red range on the
gauge as read while the unit is on. To add oil, follow these steps:
1.
Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2.
Disconnect, lockout and tagout the power supply to the starter.
3.
Wipe away all dirt around the oil filler plug.
4.
Remove the oil filler plug and add oil as required to return the oil level to the center of the green
range on the gauge.
5.
Install the oil filler plug, restore power, run and check for leaks.
DO NOT OVERFILL. The quantity required to raise the oil level from the red range center of the green
range is shown in Figure 5-6, page 52. Repeated addition of oil between oil changes may indicate
excessive oil carry-over and should be investigated.
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.
Compressor, air/oil reservoir, separation chamber and all piping and tubing
may be at high temperature during and after operation.
Excessive oil carry-over can damage equipment. Never fill oil reservoir above
the "FULL" marker.

- Following are the primary steps to be completed when upgrading
or changing the type of lubricant.
1.
Thoroughly drain system:
-
Drain oil from air end and cooler while hot.
-
Break low point connections and drain oil from pipe runs.
-
Dump oil from the filter and reinstall used filter.
