Using the SEL selector on the vacuum machine control panel, display the most suitable vacuum value “VAC” required for the food.
For example: VAC: 99

Using the SEL selector on the vacuum machine control panel, display the sealing time “SAL”, expressed in seconds, suitable for the thickness of the bag used. Uniform and correct sealing of the bags guarantees their sealing ability over time.
For example: SAL: 2.5

Using the SEL selector on the vacuum machine control panel (when prepared for the injection of technical gas – modified atmosphere), display the percentage of food-grade gas mixture “GAS” to be injected into the bag.
For example: GAS: 20

Use only bags for vacuum packaging and alimentary use (generally marked with the symbols PA/PE or Polyamide/Polythene).

>	Bags for vacuum cooking are also available on the market, which resist temperatures up to 90/110 °C.
>	It is recommended, when using CO2, to use “barriered” type bags (bags preventing leaks of this mixture) or vacuum bags with a thickness of 200 micron.
>	Position the bag correctly, avoiding folds, inside the vacuum packaging machine above the sealing bar.

Use technical food-grade gas mixtures (Nitrogen, Carbon Dioxide and Oxygen) only on the instructions of qualified staff from the manufacturing companies.
IMPORTANT:
The use of mixtures which are compatible with the product can lengthen its shelf life.
