1.2 EVER FRESH FUNCTION / DISPLAY / ALARMS:
Select the vacuum position on the container cover
and position the container in the central part of the
shelf inside the fridge compartment (vacuum station) in correspondence with the mobile containervacuum pump connection; pull the lever under the
shelf to its forward position
To activate the Ever Fresh function press the relevant button once, this will cause the icon to illuminate in
blue and the message EVER FRESH ON will scroll across the display; at this point the vacuum will be
applied automatically thanks to the intervention of a vacuum switch that detects vacuum conditions in the
container. To deactivate the vacuum function manually, press the button once (the blue icon will extinguish
and the display will scroll the message EVER FRESH OFF).
After approximately 80 seconds if vacuum conditions are not detected in the containers, the appliance will emit two initial beeps, the alarm icon will
illuminate steadily, and the message “VACUUM NOT
POSSIBLE, CHECK CONTAINER” will scroll across
the display. To reset this alarm and restore normal
operation, press the ALARM RESET button twice
