INSTALLATION
5.1
APPLIANCE DESCRIPTION
VM Series vacuum packaging machines are meant for packing dry and/or cured products, thanks to the operating principle based on creation of
vacuum inside a chamber (or tray), inside which the product in a special bag or rigid container is placed.
If provided with a special valve, the machine can also be used for vacuum-packaging of products in the above-mentioned rigid containers outside
the chamber. As explained in detail in the “USING THE APPLIANCE” Chapter, some models can be used for creating a vacuum in special “channelled”
bags outside the vacuum chamber, thereby making it possible to pack products larger than the vacuum chamber dimensions.
The work cycles (vacuum, bag sealing, devacumation and opening the cover) are carried out automatically in sequence.
In the versions with digital controls, the functions can be programmed for up to a maximum of 10 programs.

The machines basically consist of the following parts:
• a stainless steel chamber (vacuum chamber) (C) inside which vacuum is created and bags are sealed by means of sealing bars (D); it is fitted with
a transparent plexiglas cover (A) that can be opened, and through which the operating phases can be observed. The depth
inside the chamber may be changed using plastic insertion plates (B) supplied with the machine;
• a stainless steel casing (E) with the control panel and main switch located on the front, and the back is closed by a stainless steel panel.
In models VM12, VM16 and MULTIPLE 315-P8, there is a side panel (F) for topping up the oil in the pump; in other models, the topping up is done
from the back of the packaging machine (Fig. 2).
The connection for the gas cylinder (option) is provided on the back (Fig. 1);
• a high-performance vacuum pump (G) lubricated in recirculation with glass window for checking the oil level;
• an air evacuation system consisting of unions, pipes and solenoid valves which connects the vacuum chamber to the pump and the system
adjustment and/or control organs;
• an electrical system which includes the power board with fusebox, meters/thermal cutouts (in three-phase versions), control and
connections board. All the functions are controlled by a microprocessor.

ELECTRIC HAZARD! Before making the connection, always check to make sure the
electrical features of the system in the installation area are suitable and check the
direction of pump rotation.
5.2.3
CHECKING THE DIRECTION OF PUMP ROTATION IN 400V THREE-PHASE MACHINES
Procedure:
a) Check to make sure the voltage indicated on the machine nameplate corresponds to that of your mains supply (Fig. 2).
b) Insert the plug in the socket with the machine Off.
c) Check the oil level in the pump through the glass window provided on it (Fig. 1).
If the level is insufficient, follow the instructions described in the “CHANGING THE PUMP OIL” Chapter.
d) Adjust the “VAC” function on the control panel to a value between 3 and 5 (electromechanical versions), (Fig. 3A) 99% (digital versions with
sensor) (Fig. 3B) or 20 seconds (timed digital versions) (Fig. 3C).
e ) Lift the plexiglas cover after lowering the lid holder.
f) Switch the machine On by means of the main ON/OFF switch provided on the front of the machine.
g) Lower the cover to close it: the machine starts up automatically. With the pump rotating in the correct direction, the cover will remain lowered to
create vacuum (or an underpressure) inside the chamber; otherwise, the cover will rise again since air is blown in, not extracted from the
chamber. In this case, switch Off the machine immediately and have a specialist technician invert the power supply phases.
Check the direction of pump rotation every time the three-phase socket is changed!
ELECTRIC HAZARD!
Only specialist technicians must be allowed to invert the power supply phases.

WARNING! THE PUMP OIL MUST BE CHANGED PERIODICALLY; THE OIL CHANGE FREQUENCY MUST BE INCREASED
PROPORTIONALLY TO THE WORKLOAD TO WHICH THE MACHINE IS SUBJECTED. THE OIL MUST BE CHANGED EVERY
15,000 OPERATING CYCLES (CORRESPONDING TO APPROX. 100 HOURS OF OPERATION) FOR MACHINES WITH 4, 8 AND 12
M3/H PUMPS, EVERY 25,000 CYCLES (CORRESPONDING TO APPROX. 200 HOURS OF OPERATION) FOR PUMPS WITH CAPACITY
18 A 100 M3/H. IT IS ALSO NECESSARY TO REPLACE THE EXHAUST FILTER (EVERY TWO OIL CHANGES) AND THE OIL FILTER
(ONLY MODELS WITH 60 E 100 M3/H PUMPS- EVERY 1000 HOURS OF OPERATION) ON THE PUMP.
The oil and filter change frequency increases if liquids or wet products are handled; in such cases, the oil must be changed if the
machine has remained unused for a month or a longer period. A whitish, cloudy or dark and transparent oil means suction of
liquids and moisture, or that the oil is old, respectively.
In models with digital control, MULTIPLE 315, VM12 and VM16, an oil change indicator system is provided: after 15,000 operating
cycles, when the machine is started up and at the end of each cycle, the display indicates an “oil alarm”. The number of work
cycles performed can be read at any moment by means of the keys on the control panel (See page 59).
ATTENTION! Do not touch the sealing bars after sealing a bag as they may be very hot (Fig. 1).
WARNING! Do not remove the Teflon cover on the sealing bars; do not use knives or other sharp tools to remove residua from
the sealing bar: always wait for the bars to cool down before using blunt tools.
WARNING! Clean the machine thoroughly after use; clean the plexiglas cover using only a cloth dipped in water, avoid cleaning
liquids and solvents. Use the special products available on the market for cleaning the stainless steel parts. Do not use water or
steam jets as this can damage the machine’s electrical equipment.

VERSIONS WITH ELECTRO-MECHANICAL CONTROL
The VAC function is timed and expressed in seconds.
The factors that determine the time setting are as follows:
a) Volume of air to be extracted from the chamber;
b) Extent of oil usage: the pump performance reduces with increase in the number of operating hours and resulting in deterioration of the
oil characteristics.
Once the maximum volume is reached (indicated by the vacuum gauge (1) as -1.0 bar) the pump must continue to run for another 10 seconds to obtain
the maximum possible vacuum.
The VAC time setting must be suitable for actual operating conditions. If the product dimensions change with each packaging cycle, just carry out a
test run without product inside the chamber and keep the value set as valid for achieving the maximum possible vacuum in these conditions. If
packaging of products having the same dimensions is to be repeated, carry out the test run with the product-type inside the chamber, with a suitable
number of insertion plates.
BG
GB
VERSIONS WITH DIGITAL CONTROL
a) Models with vacuum sensor (percentage programming).
The machine is provided with a sensor which measures the quantity of vacuum (or the depression) created inside the chamber: this quantity is
expressed in percentage. The maximum value that can be obtained is 99%. The parameter is set using the VAC key. In models VM18, VM19, VM20,
VM1800, VM53 andVM30, once maximum vacuum is achieved, a supplementary vacuum creation time can be added using the VAC+ key,
expressed in seconds, useful for obtaining the maximum possible vacuum. In models VM12 and VM16, the VAC+ can be set by pressing the SEL
key after the VAC function programming. THE VAC+FUNCTION CAN ONLY BE ACTIVATED IF THE VAC PARAMETER HAS BEEN SET AT 99%.

INSTALLATION
b) Models without vacuum sensor (timed program).
In machines with this type of program (models VM12 - VM16 and MULTIPLE), the VAC parameter is timed and expressed in seconds. The VAC time
setting must be suitable for actual operating requirements. The time will be initially set approximately at 25-30 seconds and modified, if necessary,
in the second cycle. To obtain absolute vacuum, starting from the moment the vacuum gauge indicates -1.0 bar, the pump will continue to run for
another 10 seconds. In machines with VAC parameter time setting, there is no provision for the VAC+ function.
Packaging liquid products.
Great care must be taken in packing liquid products or products with high moisture content: the greater the vacuum percentage, the lower the liquid
boiling point.
The moment the boiling point is reached, air bubbles are formed in the product.
The consequent formation of water vapour, if extracted by the pump, will reduce the pump life.
WARNING! Before starting with packing of liquid products, run the pump by adjusting the VAC control knob or key to the
maximum value and resetting all other functions. Repeat the operation twice, in order to obtain a pump heating time of
about 2 minutes.
Set the vacuum parameter at such a value as to prevent boiling of the liquid product.
Increase the pump oil change frequency by following the instructions in the “MAINTENANCE” chapter.
Stop the work cycle immediately if liquid starts leaking out of the bag. The operation must be carried out with an inclined table
top for liquids, available as optional.
5.5.2
GAS FUNCTION (OPTIONAL)
Product packaging by flushing with gas is available as optional. The GAS option makes it possible to pack delicate products without pressing due to
pressure difference. To compensate for this pressure difference, the air is replaced with a controlled gas mixture generally consisting of 30%
carbon dioxide and 60% nitrogen. It is also possible to use antioxidant gas mixtures which help prolong the shelf-life. To select the suitable mixture,
consult the information leaflet of the best gas production Companies.
The maximum permitted percentage of gas is 60%. This percentage represents the chamber volume occupied by the gas. Beyond the 60% limit, the
pressure exerted by the sealing bar on the bag may be insufficient and bag sealing may be defective. The percentage is read by the vacuum gauge:
-0.4 bar corresponds to a gas value equal to approx. 60%; at -0.3 bar it is equal to 60% and so on. If the cover opens during the cycle, reduce the
gas flushing time. In versions with digital control, the percentage is indicated directly on the display.
5.5.3
SEALING FUNCTION (SEAL)
After vacuum creation and gas flushing (if envisaged), the machine proceeds with bag sealing by means of the sealing bar provided with sealing
wire. The sealing time varies according to the bag basic weight, environmental temperature and the quantity of work to be done. In any case, the seal
seam on the bag must be uniform, clearly marked, without melted points. In machines with electro-mechanical controls, indicatively, for a bag with
basic weight 90/100 (very thin), set the SEAL control knob on value 3.5; for bags with basic weight 150/100 (thicker) adjust the value to 4. In digital
versions, set a sealing time suitable for the bag, approximately between 2 and 4 seconds.
If it is found to be necessary to seal very thick bags, or bags made of special material (such
as aluminium), the models VM19/20/1800 and 30 are provided with a compressed air
connection (A) to increase the pressure exerted on the sealing bar. The pressure must be adjusted
upline of the air delivery pipe by means of the pressure regulator set at a maximum value of 1
bar. The use of compressed air in sealing is quite rare, since the pressure exerted by the
machine’s system is sufficient in almost all cases.
5.5.4
A
AIR
•
SOFTAIR FUNCTION (OPTIONAL)
Slow devacumation in the vacuum chamber after bag sealing makes it possible to pack delicate products or products with sharp cutting edges (e.g.
hard cheeses, speck, raw ham, ribs etc.) thereby avoiding damage to the bags due to excessively rapid decompression.
For packing cheese segments it is advisable to smooth the edges.
The parameter is set on a timed basis by means of the SOFTAIR control knob in versions with electro-mechanical controls (“SOFTAIR” key in the
digital versions). The optimum value can be determined after a few test runs before packaging the product in series.
5.5.5
JARS FUNCTION (B)
With the JARS function, it is possible to create vacuum in external containers (vacuum box) in
models provided with a special valve or pack channelled bags that are longer than the standard
dimensions permitted by the vacuum chamber, outside the machine.
In versions with elctro-mechanical control, the parameter setting is manual and is done by
turning the VAC knob to OFF.
The function is deactivated manually by turning the VAC control knob to the preset value, after
maximum vacuum is achieved (measured by the vacuum gauge).
In the digital versions, the JARS function is activated by means of the JARS key. The function is
deactivated manually after the maximum vacuum is achieved, measured by the vacuum gauge.

STOP FUNCTION
VACUUM CHAMBER
PACKAGING MACHINES
In versions with electro-mechanical controls and in digital versions of models MULTIPLE, VM12 and VM16, pressing the STOP button will cause
the machine to interrupt the function in progress immediately and proceed with the next one. It is particularly suitable for avoiding liquids extraction
or incorrect positioning of bags. In case of an emergency, turn off the machine using the main switch.
In digital versions of models VM18, VM19, VM20, VM30, VM53, VM53H, VM1800: operation is interrupted by pressing the SEAL key.
5.5.7
PUMP FUNCTION
The Pump function, which in versions with elctro-mechanical versions can be activated by means of the STOP button kept pressed for three
seconds and the plexiglas cover open, available in models VM19, VM20, VM20 TANDEM, VM1800 and VM30, allows continuous pump operation.
The result is increased pump performance over time and longer life.
The function is recommended if product packing is to be done in series.
In the digital versions, the function is activated by means of the PUMP key.

USING THE MACHINE
6.1
PREPARATION
WARNING! The product to be packed must be dry and cold to obtain maximum vacuum. The pump performance is reduced
if there is moisture in the product or the vacuum chamber. Therefore, clean the vacuum chamber and insertion plates
carefully. Soft products may be damaged by the compression in the bag when the cycle is complete. Use bags having
thickness and size suitable for the product hardness and dimensions.
1) Lower lid holder (C): the vacuum chamber plexiglas cover (D) opens.
Position the maximum number of insertion plates (E) the chamber can hold, depending on the dimensions of the product to be packed.The longest
insertion plate (in models with insertion plates of different lengths) must always be at the top as it will otherwise hinder vertical movement of the
sealing bar.
2) Choose a bag suitable for the product to be packed (the product must take up 2/3 of the bag volume). Insert inside the vacuum chamber the bag
(F),containing the product to be packed and center it on the sealing bar (G), so that the open edge projects by about 20mm beyond the bar. For
models with bar length sufficient to pack a number of bags simultaneously and for multi-bar models, distribute the bags at regular distances (=)
(Fig. 1).
PRELIMINARY CALIBRATION FOR MODELS WITH DIGITAL CONTROLS WITH VACUUM SENSOR
When used for the first time, the vacuum sensor must be calibrated according to the atmospheric pressure (depending on the
altitude of the place), as follows:
• Switch On the machine keeping the PROG key pressed simultaneously. The display shows TAR.
• Lower the lid with both hands, pressing the corners slightly. The machine will start calibration which will end automatically
after about two minutes with air returning to the chamber and consequent opening of the lid.
WARNING! The procedure must be repeated only if the machine is moved to a place at a different altitude.
