6.1.2. Switching the machine on
Set the main switch, located on the rear of the machine, to ON. As soon as the board has been switched on, display will
show the software version, then the last program being executed (P1÷P9).
6.1.3. Selecting the programs and setting up the parameters
To select the program number, just press the buttons (6) and (7).
Press button (4) to enter scheduling of the program shown at the moment. By pressing again button (4), all parameters fo
the selected program will appear one after the other. Push buttons (6) and (7) to increase or decrease the value of the
parameter shown. Parameters are stored when, while running a program, the number of the program itself will appear
on the display.
1) VACUUM
It is possible to set a value from 0 to 99,9%. The recommended vacuum percentage is 99,9%.
Scheduling of vacuum parameter is signalled through LED (9).
2) EXTRAVACUUM
If the vacuum value is set to 99.9%, press button (4) to program the EXTRAVACUUM parameter indicated by the letter
E in the last digit on the display.
This value can be set to between 0 and 30 seconds. This the length of time that the pump continues to extract air from
the hood after the machine has reached the programmed maximum vacuum level. This function is useful for porous
products where it is particularly difficult to extract the air (e.g. meat).
NB: if the programmed VACUUM value is less than 99.9%, the EXTRAVACUUM function is not displayed, and the
system proceeds to the subsequent parameter (GAS).
3) GAS
It is possible to set a value from 0 to 99%. Such a parameter cannot be higher than the vacuum one, otherwise you will
obtain an opposite function. Scheduling of gas parameter is signalled through LED (10). If the gas LED (10) is flashing,
it means the gas cylinder is not properly connected and machine will not start. Connect it properly.
NB: When scheduling a program "vac + gas", the minimum residual vacuum percentage soon after gas immission
should be higher than 60%
Example:
VAC 99,9%
GAS 40%
Residual vacuum (99,9 - 40)= 59,9%
4) SEALING
It is possible to set a value from 0 to 4 seconds. For the first working cycles it is recommendable to set a sealing time of
about 2,5 seconds and then lower it to prevent the teflon tape from burning. Scheduling of sealing time parameter is
adjusted through LED (11).
All set-up parameters are stored until they are modified.
