Installation
Transportation and placement
 The machine must be moved or transported in an upright position. The machine may
not be tilted as this can cause damage to the pump.
 Place the machine on a flat, level surface. This is essential for problem free operation
of the machine.
 Enough space must be left around the machine for good ventilation. The space must
be at least 5 centimetres.
 The ambient temperature in which the machine is operated must be between 5 ºC
and 30 ºC. When operating the machine in other ambient temperatures please
contact the supplier for advice.
Connecting the machine
 Check that the voltage stated on the machine tag is the same as the mains voltage.
 Always connect the machine correctly to an earthed socket to avoid a fire hazard or
electrical shocks (earth connection is green/yellow).
 The power cable must always be free and nothing may be placed on it.
 Replace the power cable immediately if damaged.
 Always disconnect the power if there are problems with the machine or during
maintenance, prior to starting work on the machine.
 If the machine is stationary for long periods then the power should always be
disconnected.

9
Connecting the gas flush system (if applicable)
 Connect the hose from the gas bottle to the hose coupling on the rear side of the
machine and secure it with a hose clamp.
 The diameter of the hose nipple connector for the gas bottle is 6 mm.
 Never use flammable gasses or gas mixtures containing much oxygen. There is a
danger of explosion when using the aforementioned gasses. Accidents and/or
damage caused by using abovementioned gasses void all liability on the part of
supplier as well as the guarantee.
 The gas bottles must always be correctly secured. If the gas flush function and/or the
machine is not in use then the main valve of the gas bottle must always be closed.
 The pressure of the pressure reducing valve on the gas bottle may never be set to
more than 1 bar. A higher pressure may damage the machine.
For more information about the use of gas bottles, please consult an authorised gas supplier

Machine functions
Function description
Pictogram
What does it mean?
Vacuum
Vacuum +
During the cycle, air will be removed from the chamber until
the set value has been reached. This value can be set in %,
mbar or hPa. This is the percentage or value of the pressure
in the vacuum chamber related to the normal outside
atmosphere of 1 bar (0%). The whole process is sensor
operated. Vacuum Plus is an option that continues the
vacuuming process by an additional time to create the
possibility for trapped air, inside the product, to escape.
Gas
Gas +
During the cycle, a gas is injected into the chamber and
package creating a modified atmosphere to protect the shape
or increase the shelf life of the product. The value of the gas
function can be set in %, mbar or hPa. This is the percentage
or value of the pressure in the vacuum chamber related to
the normal outside atmosphere of 1 bar (0%). Optional the
Gas Plus function can be programmed with an additional
time to increase the amount of gas inside the package.
Seal
1-2 Cut-off
When sealing, the material of the vacuum bag will be heated
and pressed together to create a hermetic seal. The
programming for this function is done in seconds. The
purpose of the 1-2 separately controlled cut-off wire is to
remove the excess foil from the remaining flap.
H2O
H2O +
The principal of the Quick Stop H2O function is that it is a
very sensitive sensor vacuum controlled system. The highly
sensitive H2O sensor is capable to detect the moment that
liquids from the product or the product itself, start to
evaporate (boiling). At that moment the control system will
interfere and switch to the next step in the process. It
therefore prevents the product from: drying out, losing

12
weight, spatter out of the vacuum bag, polluting the seal,
chamber and the oil in the pump.
The Quick Stop H2O sensor control comes standard with the
H2O PLUS option. This is extra time that the vacuuming
process continues after reaching the moment evaporation.
Red Meat
This function is especially designed for the packaging of
fresh meat. It is added to the normal vacuum function to
prevent degassing from the product during the sealing phase.
This degassing could create air pockets and drip inside the
package.
Sequential
vacuum
With sequential vacuum it is possible to alternate vacuum
and pause steps to create the opportunity for trapped air
inside a product to escape from the core. In total it is possible
to program a maximum of 5 steps.
Soft Air
Herewith it is possible to allow the air from outside, to slowly
enter the chamber so the vacuum bag will shape itself slowly
around the product and prevent sharp edges form the
product to protrude the film, and so prevent leaks.
Print
With this function it is possible to create one or multiple
labels per cycle that can be put on to the bag. The following
data might be shown on the label: Name of the producer,
Name of the product, production date, shelf life, used gas,
achieved vacuum and recommended storage temperature.
Oil pump
cleaning
The pump cleaning program ensures that the pump is
thoroughly rinsed. During the program the pump and oil
reaches operation temperature so that the oil absorbs the
moisture and contaminants and filters them. The high
temperature enables any moisture in the pump to evaporate
minimising the risk for corrosion.

13
External
Vacuum
With this function it is possible to vacuum special food
containers outside the machine. The vacuum value can be
set in %, mbar or hPa. This is the percentage or value of the
pressure in the food container related to the normal outside
atmosphere of 1 bar.
Menu
Menu is used the change machine setting such as language,
printing options
The functions H2O (and H2O Plus), Gas (and Gas plus), 1-2 Cut-off seal require purpose-
specific parts to be installed in the machine before they can be activated. The Printer and
External Vacuum require additional parts before they can be used. Contact your supplier for
more details.

14
Guideline for function values
For each function, values can be set when you are authorized as an Owner. In order to
understand the consequence of the set value, the table below explains the consequences of
giving a low or high value for each function.
Function
Range
Guideline
Vacuum
2-700 mbar
30-99.8%
As a rule of thumb: the higher the vacuum, the less
oxygen remains in the package and thus the longer is
the shelf life of the product. There are exceptions to
this rule.
Vacuum Plus
0-20 sec
This is the time that the vacuuming continues after the
maximum vacuum has been reached. This to allow
entrapped air to escape from the product.
Gas
2-700 mbar
0-70%
The two main reasons for gas flushing are; first to
increase shelf life by the chemical reaction between
gas and the product. Secondly to protect fragile
products that otherwise will be damaged by the
vacuum bag. The best way to determine the right
setting is trial and error. More gas in the vacuum
chamber does not always result in more gas in the
packed product.
Gas Plus
0.1-5.0 sec
If desired gas flushing can be continued in time while
the sealing system is closing. The best way to
determine the right setting is trial and error. Allowing
more time r does not always result in more gas in the
packed product.
Red Meat
2-700 mbar
30-99.8%
As a rule of thumb: the higher the vacuum, the less
oxygen remains in the package and hence the longer
the shelf life of the product.

15
H2O
2-700 mbar
If the pressure decreases, the boiling temperature of
water decreases. This law of physics might cause a
product to boil. Besides polluting the machine this
creates a weight and quality loss to the product that is
being packed. By enabling the H2O function, this
special sensor will detect this point of evaporation and
arranges the program to continue from vacuuming to
sealing. The value that can be set is the maximum
vacuum value that can be reached. Please note that
this vacuum value can only be reached if the product
does not start to boil.
H2O Plus
0.1-5.0 sec
This is the time that the vacuuming continues after
detecting the evaporation point. Because of the
evaporation there might occur a minor shockwave
pushing all remaining air from the bag. The best way
to determine the right time is trial and error.
Sequential Vacuum
Holding time
2-700 mbar
30-99.8%
0.1-5.0 sec
In case the Vacuum Plus time is not effective enough
to allow entrapped air to escape, the Sequential
Vacuum should be enabled. In a maximum of 5 steps
vacuuming is alternated with a holding time. Each step
creates a deeper vacuum than the previous step.
Seal time
1-2 Cut-Off time
0.1-6.0 sec
This is the time that sealing wire and/or the cut-off
wire are heated. The longer the time, the more heat is
transferred to the bag.
Soft-air
1-20 sec
The time that the air is softly released in the chamber
after sealing has taken place. To best way to
determine the right time is trial and error.
Pump Cleaning
15 minutes
No settings to be determined.
External Vacuum
2-700 mbar
As a rule of thumb: the higher the vacuum, the less
oxygen remains in the package and thus the longer is
the shelf life of the product. There are exceptions to
this rule.
