Vacuum De-gas and Vacuum
Auto-Fill
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
Activ e 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 confir m.
12. If necessary, press the Abort/Cancel button ( )
to cancel auto-refill.
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).
17. Open the shutoff valves at the base of the tanks.
This procedure is for assemblies with a Vacuum
Tree Manifold, Agitator, and Auto-Refill. See FIG.7
on page 20 for part references.
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.
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.
