1.Models with ADM: To prevent machine movement,

press the Machine Disable Mode key (). Models with SDM: To prevent machine movement, press the Red button .

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

3.If the tank lid has a fill port, turn off any systems that might refill the tank during the vacuum de-gas pro- cedure.

4.Close the fill port ball valve (1034).

5.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).

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

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

8.Turn on the vacuum pump.

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

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

11.Turn off the vacuum pump.

12.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.

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