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 sta-

tion) in correspondence with the mobile container-

vacuum 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 condi-

tions are not detected in the containers, the appli-

ance 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
