5.5.6 STOP FUNCTION
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 APPLIANCE
6. 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.
