Section 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.
Keep in mind that the machine must not be set up upon uneven ground. Especially with
mobile models, the weight of the pump might then cause warping of the machine. Then the
lid will not fit correctly.
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 recommanded by the producer. Never
exceed maximum quantity of oil indicated, when adding or changing oil. Verify weekly.
Normal ambient temperature for the vacuum pump is between 10 to 70oC.For temperature
below 10oC; it is recommended to use synthetic oil. Please consult factory and pump
manufacturer manual for more information or when ambient temperature are outside
normal limits
1.1. Connections
1.1.1. Electric connections
Electrical connections must be made by qualified personnel. This person must make
sure that the electrical entry corresponds to the proper voltage and amperage of the
machine. GROUNDING INSTRUCTIONS: This appliance must be connected to a
grounded, metal, permanent wiring system; or an equipment-grounding conductor must
be run with the circuit conductors and connected to the equipment-grounding terminal or
lead on the appliance. A qualified electrician should be consulted if there is any doubt
as to whether an outlet box is properly grounded.
All vacuum machines are supplied with an electrical schematic drawing. An important
step in connecting the machine is to make sure that the pump turns in its correct
rotation.
The pump should not rotate more than 3 to 4 seconds in the wrong rotation or it
may cause serious damage. The proper rotation is indicated by an arrow on the
pump motor.

Section 2- Operation
2.1. Working principles
A vacuum packaging cycle is made of 3 stages. First the vacuum is made, the air is
completly 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, if the product is delicate. 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 50 cm(2") past the seal bars. The product should be
centered in height in relation to the seal bar by adjusting the spacers provided.
To obtain a good seal, make sure that no residue of fat is left between the bag's inner sides
where sealing is done.
2.2. Special packaging
2.2.1. Gas flushing (option)
There is an atmospheric pressure of 1 kg/ sq. cm (14 lbs/sq. inch) 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
gas (nitrogen or carbon dioxide) before sealing after evacuation.
For gas flushing, the bags are placed on the sealing bars, the open end placed over
the gas nozzles mounted alongside the sealing bar. After evacuation, the vacuum
valve closes and the gas valve opens. Gas time (sec.) can be set in the program
menu.
The necessary gas tank and pressure valve mounted on tank is not supplied, The
pressure of the gas regulator should be set at approximately 1/3 kg/sq. cm
( 5 lbs/sq.inch.). Each machine has an adaptor for gas connection when gas flush
option is ordered.

2.2.2. Top and bottom sealing (option)
When sealing aluminium laminate bags (especially bags for e.g. coffee) it is imperative
to have an upper and a lower sealing bar.
2.2.3. Electrical bag cut (option)
This option is used to obtain a package that the excess bagtail is cut off close to the
seal (cannot be used with top and bottom sealing).
2.3. Vacuum packaging operations
