Locking position (Fig. 17, emergency
valve completely closed): The hand lever

from backwater during longer periods of
absence (e.g. holidays).
Connected draining points are still drai-
ned. The emergency valve must be re-
leased again for normal operation.

The backwater flap works as a pipe bar-
rier. This function is only considered as
protection from backwater during longer
periods of absence (e.g. holidays).
Connected draining points are still drai-
ned.
After return, the emergency valve
must be released again for normal
operation: by pressing the TEST key
(flap) again.
Make sure that there is no backwater
when this takes place.
The ventilation (see spare parts section 6) 4.8 Servicing the ventilation
must be cleaned regularly and the activa-
ted carbon filter (Fig. 18) must be changed
annually or as required.
The ventilation must be cleaned and
checked after every pump failure.
