OPERATION

UT THE

HAMBER

NDER

ACUUM

Option 1:

Vacuuming down with a pump connected to the cabinet vacuum port.

Note:

You may leave the chamber under vacuum to prepare for setting a temperature and then

setting the Over Temperature Limit.

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 show

the chamber pressure decreasing.

Holding at Vacuum

•

Continue evacuating the chamber throughout the baking

application to vent outgassed byproducts.

•

When first putting the oven into operation, hold under

vacuum for at least ten minutes.

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

upward to 760 torr.
