INSTAllATION
10) Calibrating the vacuum sensor.
The vacuum sensor must be calibrated so as to adapt the reading to the elevation of the installation site.
Without this adjustment, the machine cannot create an adequate vacuum.
Proceed as follows:
Turn the machine on using the "ON/OFF" main switch and simultaneously press the
"PROG" button.
Lower the lid.
The machine starts the cycle, which ends after approximately 2 minutes.
The lid opens at the end of the calibration.
The machine returns to the default program or the previously set program.
