The oven chamber must be drawn down to at least -3 inHg (-76 mmHg or -10 kPa) in order to seal. 

Option 1:

 Vacuuming down with a pump connected to the vacuum port. 

End of Procedure 

Evacuate the Oven Chamber 

1.  

Verify the Vacuum and Vent Valve controls are in the closed position 

 

 

This protects your vacuum pump from exposure to streaming 

atmosphere. 

2.  

Turn on your vacuum pump 

 

 

3.  

Open the oven Vacuum Valve

 

 

Turn the control all the way counterclockwise. 

 

 

The Vacuum Gauge on the front panel 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. See page 45. 

Hold Under Vacuum

 

 

Continue evacuating the chamber throughout the baking application 

to vent outgassed byproducts. 

Backfill the Oven Chamber

 

4.  

Close the Vacuum Valve 

 

Turn the 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 Valve

 

 

The chamber pressure gauge will count upward to 0 inHg.
