Indoor Installation - wisy WFF 150 Anleitung Für Einbau Und Betrieb

Indoor installation

● Please observe the safety guidelines below regarding the indoor
installation of the WFF.
● The maximum rainwater inflow must not exceed 12.8 l/s for the
WFF 150 or 4.2 l/s for the WFF 100. Use the local rainwater data
applicable to your area as a basis for calculating the maximum
size of connectable collection
surface for your region.
● If the WFF rinsing water outlet is
connected to a storm drain, the
WFF must always be installed
above the maximum backwash
level of the storm drain. If the
WFF rinsing water outlet is con-
nected to a soakaway, the WFF
must always be installed above
the maximum backwash level of
the soakaway.
● The WFF must be installed ex-
actly vertical and stable. For
this reason, it is strongly recom-
mended that the WFF be mount-
ed using the original WISY wall bracket. If other parts are used to
secure the WFF, it must be ensured that clamps placed around the
WFF housing are installed free of tension and do not subject the
WFF housing to deformation pressure.
● The straight tube in front of the rainwater inlet ('settling length'
in order to calm down the incoming water) must have a minimum
length of 0.5 m. The nominal size and the gradient of this straight
tube have to correspond to the nominal size and gradient of the
WFF rainwater inlet.
