PRIMING COMPRESSOR AND OIL FILTERS

NOTE

Running the compressor oil pump at this point will help lubricate the compressor bearings and shaft seal surfaces.

(Reference Figure 3-19)

11.Open shut-off valve(s) (8) at oil filter inlet(s).

12.Close oil bypass shut-off valve (5).

13.Open oil mixing valve (7) via control panel. In Manual Mode, change “Manually Open (%)” value to “100”.

14.Run oil pump (6) for approximately 20 seconds only.

15.Stop oil pump (6) and wait for a minimum of 30 min- utes. This will allow oil in the compressor (2) to drain and oil level (9) in separator (2) to settle.

NOTE

Oil mixing valve can remain in Manual Mode since the setpoint will change the mode to Auto when reached. For further details, see PLC Compact Logix manual.

16.Refer to Pre Start-Up Checklist and ensure all items are ready prior to starting the compressor.

17.When ready, run compressor unit and allow it to reach normal operating temperature.

18.Using a properly selected oil pump, connect oil pump to suction oil charging valve (1). For suction oil charging valve location, see Figure 3-16.

19.Open suction oil charging valve (1) and fill oil separa- tor (3) to Normal Operating Level.

20.Once the Normal Operating level has been reached, shut off the oil pump and close the suction oil charg- ing valve (1). Disconnect and remove oil pump.
