Section 4 • Operation

NOTE

Plugs are installed on bleed valves. Remove and install plugs prior to and after bleeding. Ensure to keep valves closed when removing and installing plugs.

6.Slowly open suction oil charging valve and bleed remaining pressure in compressor unit to atmo- sphere, see Figure 4-13. Leave suction oil charging valve in open position.

7.If equipped with pressure indicator on purge line, open shut-off valve to pressure indicator.

8.If not equipped with pressure indicator, refer to PLC main screen for discharge pressure when purging.

PURGE

CAUTION

Do not purge compressor unit with oxygen. Failure to

comply may result in damage to equipment.

CAUTION

Do not allow compressor to spin while purging. Regulate purging pressure as needed. Failure to comply may result in damage to equipment.

Discharge

Status

9.Connect purging hose from gas cylinder to suction oil charging valve.

NOTE

Purging is performed through the suction oil charging valve so that trapped gas can be pushed out of the compressor. This will help minimize metal surface oxidation of the compressor (due to the gas) while not in service.

10.Purge compressor unit for 4 minutes. Check pres- sure indicator or discharge status on PLC main screen to make sure pressure is increasing.

11.Close shut-off valve on purge line while still purging.

12.Observe discharge pressure of compressor unit through the PLC main screen.

13.Allow pressure to build to approximately 10 psig in the compressor unit.

14.Once pressure is reached, stop purging and close suction oil charging valve.

15.Wait 10 minutes to make sure there are no leaks and that the pressure is holding.

16.Remove purging hose from suction oil charging valve.
