OPERATION

VACUATING AND

ACKFILLING THE

VEN

HAMBER

Put the oven chamber under vacuum for at least 10 minutes

when first putting the oven into operation

in a new location to verify the integrity of the vacuum supply system.

Reminder:

The oven must be plumbed to a vacuum supply source before starting this procedure.

End of procedure

Evacuate the Oven Chamber

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

•

This protects your vacuum pump from exposure to streaming

atmosphere.

Turn on your vacuum pump

Open the oven Vacuum Valve

Turn the control all the way counter clockwise

•

The Vacuum Gauge on the front panel should

count up from zero as more atmosphere is

evacuated.

•

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

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.

Slowly open the Vent Valve

The chamber pressure gauge will count down to zero.
