Standby > Configuration > Test settings > Evacuation time & ventilation
Note the following information for the "Evacuation time & ventilation" menu:
"Venting: Deactivated" or "Venting: Manual" prevents the unintentional venting of
vacuum devices connected to the inlet flange.
With the setting "Venting: Deactivated", the inlet flange can only be flooded by
changing the settings in the menu "Evacuation time & ventilation".
With the "Venting: Manual" setting, you can perform a targeted venting in the
"Standby" window by pressing the STOP button for more than 2 seconds.
