CONTROLS
Note: Backfilling is the process of restoring atmosphere to the vacuumed down oven chamber. This
is done by flowing gas into the chamber from a safe gas source connected to one of the gas-
in ports on the back of the oven.
Vacuum and Backfilling Gas Supply Valves
Vacuum Valve Control
The large valve handle labeled Vacuum adjusts the level of vacuum
draw applied to the oven chamber through the 1/4 Inch (6.35 mm)
Vacuum Port on the back of the oven.
•
When open , this valve allows a vacuum pump connected to
the Vacuum Port to pump down the oven chamber.
•
In the
closed
position, the valve closes and seals the port.
Vent (Bottom)
Turning the Vent handle to the open position flows gas from the Purge and Pressurize supply to
flow into the oven chamber.
•
When the Vent valve handle is in the closed position, the oven chamber is isolated
from the Purge and Pressurize gas supply.
•
The Vent valve should be kept in the closed position when not backfilling.
Backfill (Top)
Warning
: Do not open this valve unless the Backfill gas-in port on the back of the oven is connected
to a safe gas supply. The port must remain capped when not connected.
Avertissement: N'ouvrez pas cette vanne à moins que l'orifice d'entrée de gaz de remplissage à
l'arrière du four ne soit connecté à une alimentation en gaz sûre. Le port doit rester fermé lorsqu'il
n'est pas connecté.
•
This valve opens and closes the Backfill port on the back of the oven.
•
This is intended for an optional gas supply used to backfill the oven chamber.
•
Before opening this valve, always verify
the Backfill port is connected to a safe
gas supply.
•
The Backfill port must be capped when not connected to a supply to prevent potentially
explosive gases or vapors from reaching the oven chamber.
