ADDITION OF OIL BETWEEN CHANGES – Oil losses (typically 2 ppm) from the oil separation system may
require replenishment between scheduled changes. If (during operation only) the sight glass shows oil level
below the "min" mark, add oil per following steps: (See Figure 5-1.
1.
Be sure the unit is completely off and oil sump is depressurized.
2.
Disconnect lockout and tagout the power supply to the compressor package.
3.
Close (when provided) valve isolating compressor package from air system.
4.
Wipe away all dirt around the oil filler plug.
5.
Remove the oil filler plug (1) and add (or drain by removing plug (3) if correcting high level) sufficient oil to
adjust its level to nearly the top of the measuring rod.
6.
Install the oil filler plug, open isolation valve (when provided), restore power, then run unit to check for leaks.
Note that repeated addition of oil between oil changes may indicate excessive oil carry-over and should be
investigated.
Excessive oil carry-over can damage equipment. Never fill oil reservoir above
the "max" level mark.
