Operating the XO-VAC+ Vacuum System¶

The Vacuum Control Panel¶

Danger - Fire & Electric Shock Hazards

Do not operate the XO-VAC+ Thermal System without the chamber being under vacuum!

Danger

Only vent the chamber if it is at temperatures 5 degrees above the water dew point and below 40C. You can determinee the current chamber temperatures by connecting to XO-VAC+.

Warning

Do not manually vent the vacuum chamber if the turbovacuum pump is still running at full speed. The turbopump will get damaged by any sudden vent to atmosphere.

The vacuum gauge and the vacuum pumps can be controlled using the Vacuum Control Panel located on the front of the Vacuum Control box.
