Operation
External Vacu-
um
This function allows special food containers to be vacuumed out-
side the machine.
The options to set the vacuum value are the same as for stand-
ard vacuuming (see External Vacuum (optional) on page 22).
4.3 Sealing System
The sealing system closes the opening(s) of the bag to retain the vacuum and/or gas in the bag.
The end of the bag can optionally be cut off by the sealing bar.
Figure 2: Overview of the Sealing System
1.
Sealing bar
The sealing bar consists of the following components:
•
Sealing wires: during the sealing process, the sealing wires are heated for a certain time
causing the edges of the vacuum bag to melt together.
•
Cut-off wires (optional): A cut-off wire is heated in such a way that the foil of the bag
partially melts, allowing the excess foil of the vacuum bag to be removed easily.
•
Teflon tape: sealing and cut-off wires are covered with Teflon tape to prevent the bag from
sticking to the sealing bar.
Consult Replacing the Sealing Wire on page 25 for more detailed information about
maintenance.

Silicone holder
Opposite the sealing bar is a silicone holder which provides counter pressure on the cylinders
(Replacing the Silicone Rubber of the Silicone Holders on page 27).
3.
Sealing mechanism
The sealing bars are pressed onto the vacuum bag by cylinders. By connecting the inlet of the
cylinders with the atmospheric pressure outside, they press the sealing bar onto the bag.
