Filling the interstitial space with leak detection
medium
Press and hold the "Filling" button for approx. 5
sec. until the yellow LED flashes. Filling is
activated.
On reaching the operating pressure, the yellow
LED goes off and filling stops.
When pressure falls because of pressure
compensation processes, filling can be activated
again to ensure that the interstitial space is filled
completely.
If you hold the button for longer than 10 sec., this
triggers the alarm. It goes off again just after you
release the button.

Press and hold the button "Audible alarm" until
the "Alarm" LED flashes quickly, then release. A
value for tightness is shown when the "Alarm"

For this check, the leak detector must have
completed at least 1 automatic refilling interval in
normal operation (i.e. without filling with an
installation pump) for a meaningful statement.
