1. Setting up the machine
Before choosing the site for the machine, please consider that you will also need
room for packaged and non-packaged products apart from the space needed for
the machine itself.
Before starting to work, check the oil view glass on the pump, if there is a sufficient
quantity of oil in the pump. Never use oil other than recommended by the producer.
Never exceed maximum quantity of oil indicated, when adding or changing oil.
Verify weekly.
Normal operating temperature for the 350/350D is 4C to 32C (39F to 90F).
Vacuum pump is filled with synthetic oil that can be used in that range of
temperature.
2. Electrical connection
Electrical connections must be made by qualified personnel. This person must
make sure that the electrical entries correspond to the proper voltage and
amperage of the machine. GROUNDING INSTRUCTIONS: This appliance must be
grounded. In the event of malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of electric shock. This
appliance is equipped with a cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an appropriate outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
DANGER Improper connection of the equipment-grounding conductor can result in
a risk of electric shock. The conductor with insulation having an outer surface that
is green with or without yellow stripes is the equipment-grounding conductor. If
repair or replacement of the cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal. Check with a qualified electrician
or serviceman if the grounding instructions are not completely understood, or if in
doubt as to whether the appliance is properly grounded. Do not modify the plug
provided with the appliance if it will not fit the outlet; have a proper outlet installed
by a qualified electrician.

3. Operation
a. Working principles
A vacuum packaging cycle is made of 3 stages. First the vacuum is made, the air
is completely taken out of the chamber and from bag containing the product (see
figure 1). Then it is possible to inject neutral gas from the nozzles, gas flushing
extended product shelf life and also act as a cushion for delicate product. Finally, a
mechanism pushes the sealing bar to the rubber support to seal the bag.
To obtain nice packages, the products and the bags have to be of proportional
sizes. The bag's opening should never exceed 5 cm (2") past the seal bars. The
product should be centered in height in relation to the seal bar by adjusting the
spacers provided (see figure 1).
To obtain a good seal, make sure that no residue of fat is left between the bag's
inner sides where sealing is done.

b. Gas flushing (option)
There is an atmospheric pressure of 1 kg/cm2 (14 PSI) upon products when fully
evacuated. Products which can be damaged by high pressure must be packaged
with a partial vacuum, or the pressure must be counterbalance by inflating the bag
with neutral gas.
For gas flushing, the bags are placed on the sealing bars, the open ends placed
over the gas nozzles mounted alongside the sealing bar. After evacuation, the
vacuum valve closes and the gas valve opens. Gas quantity (%) can be set in the
program.
The necessary gas tank and pressure regulator mounted on tank is not supplied,
The pressure of the gas regulator should be set at approximately 1/3 kg/cm2 ( 5
PSI ). Each machine has an adaptor for gas connection when gas flush option is
ordered.
c. Electrical bag cut (option)
This option is used to obtain a package that the excess bagtail is cut off close to
the seal.
d. Pressure regulator (option)
This option is used to obtain more sealing pressure between the sealing bar jaw.
Suggested option for low vacuum level packaging or high level gas flushing. Also
recommended for hard to seal laminated bags. Each machine has an adaptor for
compressed air connection when pressure regulator option is ordered.
Recommend pressure regulator adjustment is 1 kg/cm2 (14 PSI), maximum setting
1.3 kg/cm2 (20 PSI),
