WARNING

Avoid skin contact with any condensate or oil. Wear rubber gloves and a face shield when working with condensate or oil. Failure to comply may result in serious injury or death.

1.Shut down the compressor unit, refer to Stopping/ Restarting procedure in Section 4.

2.Turn disconnect switches to the OFF position for the compressor unit and oil pump motor starter, if equipped.

3.Close shut-off valves located before the strainer and at the oil filter(s) inlet.

4.Position drain pan under drain valve.

5.Open strainer drain valve and allow oil to complete- ly drain, see Figure 5-7.

6.Remove bolts securing strainer cover to strainer. Remove strainer cover, gasket and element. Retain gasket.

7.Inspect gasket for damage, replace as required.

NOTICE

Dispose of the oil in a appropriate manner following all Local, State and Federal ordinances regarding the disposal of used oil.

To clean the oil pump strainer, proceed with the follow- ing steps.

WARNING

At shutdown, open any other valves that may trap liquids to prevent serious injury and/or damage to equipment.

WARNING

Follow local lockout/tagout procedure. Failure to comply may result in serious injury, death and/or damage to equipment.
