MACHINES WITH ELECTRO-MECHANICAL CONTROLS
BASIC OPERATION (VACUUM AND SEALING BAGS)
1) SWITCHING ON
Turn on the main switch on the front of the machine; a LED on the control panel
(models VM18/53/19/1800/20/30) or an indicator light on the switch (modelli VM12/16) lights up;
2) SETTING THE VACUUM CREATION TIME
The time may be set approximately by initially adjusting the
VAC
control knob in the value range 4.5 - 5 and must be modified, if
necessary, in the second cycle. It is therefore advisable to carry out a few test runs before starting product packaging in series,
so as to calibrate the parameter and optimize operating times.
3) SETTING THE SEALING TIME
For bags with basic weight 90/100, adjust the
SEAL
control knob to position 3.5; for bags with
basic weight 150/100, set the control knob on 4.
4) STARTING THE WORK CYCLE
Lower the lid using both hands, pressing the corners slightly
(Fig. 2)
. The machine will start the work cycle according to the
vacuum and sealing values set.
5) WORK CYCLE END
The machine automatically ends the cycle after the sealing bar cooling phase, and when the lid re-opens. Remove the packed product and check
the bag seal: it must be uniform, clearly marked, without melted points. Adjust the values set, if necessary, and then proceed with the second
cycle.
