Vacuum De-gas and Vacuum Auto-Fill

This procedure is for assemblies with a Vacuum Tree Manifold, Agitator, and Auto-Refill. See FIG. 7 on page 20 for part references.

1.Press the Select Operating Mode button ( ) repeatedly to select Shot, Sequence, or Operator (Manual) mode.

2.Close the shut-off ball valves at the base of the tanks.

3.If the tank lid requires a desiccant dryer or nitrogen pump installed, install one into the top ball valve of the vacuum tree manifold (1015).

4.Close the top ball valve of the vacuum tree manifold (1015).

5.Attach vacuum pump to the bottom ball valve of the vacuum tree manifold (1015) then open the ball valve.

6.Turn on the vacuum pump.

7.Turn on agitator.

8.Select Manual Auto-Refill mode. See operation manual referenced at the beginning of this manual for more information.

9.Press the Initiate Auto-Refill button (). The

Active Shot/Sequence button ( ) and Select

Operating Mode button ( ) will each change to

the Auto-Refill Tank Select button ( or ) if a valid Auto-Refill mode is enabled for both tanks.

10.Press the appropriate Auto-Refill Tank Select button

or buttons ( and/or ) to select the tanks to refill.

11.Press the Initiate Auto-Refill button () or the

Enter button ( ) to confirm.

Setup

12.If necessary, press the Abort/Cancel button () to cancel auto-refill.

If an auto-refill is aborted or times out, the software will not initiate a new auto-refill until a manually initi- ated auto-refill has completed. To complete a man- ually initiated auto-refill after an aborted or timed out auto-refill, restart at step 2.

CAUTION

If an auto-refill is stopped and not restarted as described in the previous note, the pumps may be run dry and chemical crossover at the valve may occur.

13.Continue to de-gas for sufficient time to de-gas the material.

14.Close bottom ball valve of the vacuum tree manifold (1015).

15.Turn off the vacuum pump.

16.Open the top ball valve of the vacuum tree manifold (1015).

CAUTION

Operating the tank after the vacuum de-gas proce- dure without the top ball valve open will result in pump cavitation, off-ratio conditions, and possible collapse of the tank.

17. Open the shutoff valves at the base of the tanks.
