Description of the Machine 13
4 Description of the Machine
This section provides an overview of the main components and functions. If detailed information is
available in this manual, you will be referred to the specific sections.
4.1 Overview of the Main Components
The figure below shows the main components of the system. The model shown may differ from
your machine.
Figure 1: Overview of the Main Components
1. Lid
The lid closes the vacuum chamber during the application of the vacuum. A rubber is mounted
in the lid to ensure proper closing. On machines with two vacuum chambers, the lid can be
moved from position 1 to position 2 manually. In these machines, the sealing bars and suction
inlet for the vacuum are included in the lid.
2. Vacuum chamber
The products to be packaged are placed on the work surface with the openings of the vacuum
bags on the sealing position. On machines with two vacuum chambers, the already packaged
product can be removed and new products can be placed on the free work surface during the
vacuuming and sealing process.
3. Castor with brake
The machines are fitted with four castors with brake. This allows for easy moving of the
machine to a different location.
4. Machine housing
The machine housing contains all the components necessary for the functioning of the
machine.

Description of the Machine 14
5. Control panel
This serves to operate the available control functions. Depending on your model, your
machine will have the 10-program control system or the Advanced Control System (ACS).
6. Seal system
Depending on the model, one, two or three sealing bars are mounted in the vacuum chamber.
These close the vacuum bag.
7. Vacuum pump
The vacuum pump creates the vacuum.
8. Power connection and cable
This serves to connect the machine to the power supply. The machine is supplied without an
electrical plug.
9. Gas flush system connector (optional)
After applying vacuum, a gas is injected into the packaging to create a modified atmosphere to
protect the shape of the product or increase the shelf life of the product.
10. Seal pressure connector (optional)
Where the standard model makes use of atmospheric pressure to press the seal bar onto the
vacuum bag during the sealing process, it is also possible (optional) to connect to an external
source in order to obtain a higher sealing pressure.
4.2 Description of the Packaging Process/Machine Functions
This section provides an overview of the packaging process and available machine functions.
For the functions Liquid Control (and Liquid Control+), Gas (and Gas+), Seal 1-2 Cut-off
and Soft-air, specific components must be installed on your machine before they can be
enabled. Contact your supplier for more details.
See Changing the Program Settings on page 33 for information about setting the
parameters to the correct values.
4.2.1 Packaging Process/Machine Functions
This section describes the packaging process and the machine functions. See Operation on page
25 for the realization of the specific steps of the procedure.
Step Process phase Operation
1. Preparation The operator puts the product in a vacuum bag and places it
on the work surface with the opening on the sealing position.
2. Applying vacuum The vacuum process is initiated by closing the lid.
Depending on the options you selected for your machine and
the product you are packaging, the following functions are
available:

Description of the Machine 15
Step Process phase Operation
Vacuum During the cycle, the air is removed from the chamber until
the set time or pressure has been reached, depending on
the selected model.
Applying vacuum until a set value is reached is only possible
if your machine is sensor-controlled (optional for 10-program
control system). This value can be set in %. The percentage
indicates the depth of the vacuum. This is in relation to an
outside atmosphere of 0%. In case of the Advanced Control
System (ACS), the value is indicated in percentages, mbar or
hPa.
Vacuum+ Vacuum+ is only available if the vacuum percentage is set to
the maximum.
The Vacuum+ option continues the vacuum process for an
additional time to allow any entrapped air to escape from the
product.
The Vacuum+ option is only available on sensor-controlled
machines.
Gas (optional)
After applying vacuum, a gas is injected into the package
to create a modified atmosphere to protect the shape of the
product or to increase the shelf life of the product. The value
of the gas function can be set in %, mbar or hPa or time,
depending on the control type of the machine.
Gas+ (optional)
The Gas+ option continues injecting gas during the closing
of the bars to increase the amount of gas in the package.
See Gas+ (optional) on page 35.
Liquid Control
(optional)
Liquid Control is only available if your machine is equipped
with the optional Liquid Control sensor.
With the Liquid Control option, the system is controlled by
a highly sensitive sensor. The sensor is able to detect the
moment that liquids from the product or the product itself
begin to evaporate (boil). At that time the system will proceed
to the next step in the process. This will prevent the product
from dehydrating, losing weight and/or the vacuum bag from

Description of the Machine 16
Step Process phase Operation
bursting, thus contaminating the seal, the chamber, and the
oil in the pump. See Liquid Control (optional) on page 35.
Liquid Control+
(optional)
Liquid Control+ is only available if your machine is equipped
with the Liquid Control option.
The Liquid Control+ function allows you to continue the
vacuum process for a certain time after the evaporation point
has been reached.
Red meat (optional)
This option is especially designed for the packaging of fresh
meat. It is added to the normal vacuum function to prevent
degassing of the product during and after the sealing phase.
This degassing could create air pockets inside the package.
See Red Meat (optional) on page 36.
Sequential Vacuum
(optional)
This function is only available on machines with the
Advanced Control System (ACS).
With sequential vacuum, you can alternate vacuum and
pause steps to allow air trapped inside a product to escape
from the core. A maximum of 5 steps can be programmed.
Multi-Cycle Vacuum
(optional)
This function is only available on machines with a 10-
program control system. See 10-Program Control System on
page 33.
The Multi-Cycle Vacuum option allows you to vacuum and
insert gas in steps. This provides an additional reduction in
the oxygen content.
Marinating (optional) This function is only available on machines with the
Advanced Control System (ACS).
This function is especially designed to accelerate the
marinating of a product. This program allows definition of up
to 5 vacuuming steps with intermediate ventilation steps.
The vacuuming steps have a fixed vacuum value of 80%,
except for the last step. The last vacuuming step has an
adjustable value of up to 99.8%. This also allows setting

Description of the Machine 17
Step Process phase Operation
Vacuum+. The intermediate ventilation steps have a fixed
value of 40%. After the last step, sealing takes place.
Liquid Control: It is also possible to enable Liquid Control.
This function will then only be active during the last
vacuuming step. If, for instance, 3 vacuuming steps have
been defined, Liquid Control will be active during the third
step. Vacuum+ is also possible here; however, this would be
a Liquid Control+ setting of 0.1 sec with a maximum of 5.0
sec.
Tenderising
(optional)
This function is only available on machines with the
Advanced Control System (ACS).
This feature has been designed to keep the chamber at a
pre-determined vacuum level for a certain time. This is done
to tenderise or degas the product.
During the cycle, the air is removed from the chamber until
the pre-set value has been reached. Once this value has
been reached, the chamber will remain at this vacuum level
for the pre-set time.
Sealing The sealing bars are pressed against the vacuum bag and
melt the bag closed.
3.
Seal During the sealing process, the material of the vacuum bag
is heated and pressed together to create a hermetic seal.
The programming of this function takes place in seconds.
Optionally, a cut-off wire is available. The purpose of the
cut-off wire is to remove the excess foil. Depending on the
selected model, the cut-off wire is controlled simultaneously
with or independent from the sealing wire (Seal 1-2 cut-off).
Decompressing The vacuum is removed from the vacuum chamber by letting
air into the chamber.
4.
Soft-Air (optional for
the Falcon)
This function allows air from outside to slowly enter the
chamber so the vacuum bag will shape itself slowly around
the product. This prevents sharp edges of the product from
puncturing the foil and causing leaks.
5. Opening the
vacuum chamber The lid opens.

Description of the Machine 18
Step Process phase Operation
6. Removing the
product The operator can remove the packaged product from the work surface.
4.2.2 General Functions
Function Pictogram Operation
Cleaning of the
oil pump
The pump cleaning program ensures that the pump is thoroughly
rinsed. During the program, the pump and oil reach the
operating temperature, so the oil and moisture are separated
and any contamination is filtered. The high temperature causes
any moisture in the pump to evaporate, thus minimising the risk
of corrosion.
Menu This menu is available on machines with ACS control. The menu
is used to change the machine settings, such as language and
print options.
Printing
This function is available on machines with ACS control.
This function allows the creation of one or more labels per cycle,
to be put on the packaging.
The following information can be printed on the label: name of
the producer, name of the product, production date, shelf life,
achieved vacuum, initials of the user, recommended storage
temperature and an information field (for example to indicate the
gas used).
External
Vacuum
This function is available as an option, depending on the type of
machine.
This function allows special food containers to be vacuumed
outside the machine.
The options to set the vacuum value are the same as for
standard vacuuming (see External Vacuum (optional) on page
37 for 10-program control system or External Vacuum
(optional) on page 45 for ACS control).
Sleeper option The Sleeper option shuts down the machine after a certain time.
The default setting is 10 minutes. If you wish to change this time,
please contact your supplier.

Description of the Machine 19
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 (Including Sealing Cylinder)
Figure 3: Overview of the Sealing
System (Including Seal Bag)
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 54 for more detailed information about
maintenance.
2. Silicone holder
Opposite the sealing bar is a silicone holder which provides counterpressure on the cylinders/
seal bag (Replacing the Silicone Rubber of the Silicone Holders on page 56).
3. Sealing mechanism
The sealing bars are pressed onto the vacuum bag by bellows or cylinders.
By connecting the inlet of the bellows or cylinders with the atmospheric pressure outside, they
press the sealing bar onto the bag.
Additional sealing pressure (optional) may, depending on the model you have, be used if
additional pressure force is needed.
See Technical Data on page 63 and Connecting the Machine on page 23 for more
information.

Description of the Machine 20
4.4 Vacuum Pump
