9 Operation
This section is aimed at the machine operator. It will tell him everything that he needs to know in order
to operate the machine, from starting the machine to operating and stopping it.
9.1
General instructions
§
Do not vacuum pack live animals!
§
Do not pack rotten foodstuffs!
§
Do not put goods into circulation if the welded seam is not intact!
§
Only use approved vacuum bags!
§
Only use approved inert gas!
§
Do not leave things lying on the lid of the vacuum chamber!
§
Interrupt what you are doing if the vacuum chamber becomes soiled (e.g. if liquid leaks, etc.). Switch
the machine off immediately and unplug it from the mains. Clean the vacuum chamber first of all,
then the filling plates and the welding bars. Dry any parts which get wet.
9.2
Requirements for operation
The following requirements must be met before the machine can be put into operation:
§
The machine must be correctly i nstalled and connected, as described in the section on “Installation”.
§
The vacuum chamber must be clean and dry.
9.3
Preparation
Before you start packaging, get the product being packaged ready, get the packaging ready and adjust
the machine to suit the product being packaged.
9.3.1
Preparing the product
Read “Suitable products” in the section on “Safety” to find out which products are approved for
packaging with the machine.
The maximum product size depends on the dimensions of the vacuum chamber. In order to find this out,
refer to “Dimensions” in the section on “Technical data”.
In order to achieve the best possible packaging results, heed the following points when you prepare the
product for packaging:
§
Divide the product into portions which are small enough to ensure that the opening of the bag does
not become soiled as the bag is filled.
§
Leave cooked products to cool down, if possible.
The boiling point drops in the vacuum, as a result of which warm products start to evaporate
increasingly. This reduces the quality of the vacuum and the pumping capacity. Serious evaporation can
be prevented significantly by selecting the appropriate type of vacuuming process. For more
information, read the description of the different forms of vacuuming under “Vacuum generation” in the
