End of Procedure
Pump Down the Oven Chamber
1.
Verify the Vacuum, Vent, and Backfill Valve controls are in the closed position
•
This protects your vacuum pump from exposure to
streaming atmosphere.
2.
Turn on your vacuum pump
•
If using a building supply system, verify it is providing
vacuum to the oven vacuum port.
3.
Open the oven side Vacuum Valve
Turn the control all the way counterclockwise.
•
The Vacuum level on the main controller
should show the chamber pressure
decreasing.
•
The achievable vacuum level is dependent on altitude
above sea level as well as the vacuum supply efficiency
and the volume of outgassed byproducts.
Holding at Vacuum
Continue evacuating the chamber throughout the baking
application to vent outgassed byproducts.
Backfilling the Oven Chamber
4.
Close the side Vacuum Valve
Turn the side Vacuum Valve control back to the closed position
(clockwise) to protect the vacuum pump from extended exposure
to streaming atmosphere.
•
The pump may remain on.
5.
Slowly open the Vent or Backfill valve per your SOP
•
The chamber will return to room pressure.
