General installation hints

● Installation and connection sizes can be seen in the dimension
drawings. When the inspection opening is raised by use of an
extension tube, the additional length must be included in the
calculation.
● The extension tube can be shortened to the required length along
the saw grooves.
IMPORTANT: The extension tube and the end ring are to be con-
nected by the supplied screws to ensure a proper connection.
After closing the housing cover insert the safety screw by hand!
● Before installing the filter in existing pipework, make sure that there
is room to install the rainwater inlet tube at the following vertical dis-
tance from the drain connection: WFF 150: 50 cm (19,6 inch)
● The vertical distance between the rainwater inlet
tube and the connection to the storage tank
must be: WFF 150: 34 cm (12,4 inch)
WFF 100: 21 cm (8,3 inch)
● If the installation is completely new, the re-
quired installation depths of incoming and
outgoing tubes must be calculated. A 'set-
tling length' of at least 50 cm in front of
the rainwater inlet must be included in the
calculation.
● The diameter of the drain tube must not be smaller than the
diameter of the rainwater inlet tube in order to avoid any
constriction to the WFF cross-section.
● If these installation conditions cannot be met, the WFF cannot be
installed. In this case we recommend the WISY standpipe filter
collector for installation in the downpipe or the WISY LineAr-Filter
100 for installation in the cistern.
● To ensure that the WFF can withstand the weight of vehicles of up to
30 t (according to ATV test) an appropriately compacted subsoil or
concrete slab is required. If the installation is too deep or the load is
too high, the WFF must be placed in a concrete shaft.
