Outdoor Installation - wisy WFF 150 Anleitung Für Einbau Und Betrieb

Outdoor installation

● Remove the safety screw
● Remove the transport packing cardboard from inside the housing.
● Dig a hole of suitable size in the ground. Compess the soil under the
filter.
● Insert WFF, align connections and connect pipes.
Important: the required slope of the pipes is given by the Rainwater
Inlet and must be observed. Install the WFF housing exactly
vertically. If necessary, an extension tube can be used to make the
inspection opening flush with ground level.
● The end of the extension tube with the moulded collar is placed
directly on the WFF housing and fastened securely by inserting the
stainless steel screws supplied through the pre-drilled holes
before the WFF is placed in the ground.
● The saw slits in the extension tube can be cut to make the
inspection opening flush with ground level.
● The vortex filter is not a closed system, it must not be flooded for
a longer period of time. In loamy soil, provide drainage underneath
the filter, or seal the joints of the filter housing from the outside with
a suitable sealant before installation. In case of non-observance
seepage water may enter the filter from the outside.
Use the included stain-
less steel screws for the
secure connection of
filter housing, extension
pipe and end ring.
The end ring enables a
surrounding paving. With
an counterclockwise
turn the cover can be
removed, after loosening
the safety screw
