•
The Chamber Vent Port (Backfilling) – 1/4 inch (6.35mm) OD
o
This intake port allows external atmosphere to backfill the oven chamber when the

KF-25 Fitting
o
This large fitting is normally used to introduce sensor probes into the oven chamber
using a vacuum feed through.
o
Optional : A vacuum supply can be connected to the KF-25 fitting for increased
efficiency in vacuuming down the chamber. However, the Vacuum Valve control on
the front control panel will not affect the level of vacuum and must be set to closed
to prevent atmosphere from entering the chamber through the 3/8” Vacuum Port.
