it should be assured that no foreign objects
such as trash or debris are in the valve.
Recessed cover for on-site tiling (ma-
ximum tile height including tile adhe-
sive – 15mm)
The recessed cover (series X) allows the
flooring material (tile for example) to also
be installed in the recessed cover so that
the finished cover matches the flooring
surface.
3.2 Extended Depth Installation (Part
Order Number 83070)
If the Staufix FKA is to be installed in an
high groundwater or high earth moisture
area then the instructions in Section 3.4
must be followed. Depending on the
required depth of installation, either one
or two of the KESSEL extension sec-
tions can be used. Connection gaskets
should be properly lubricated as stated
previously. In order to reach the properly
installation height when using extension
section(s) it may be required to shorted
the top upper section.
Caution! Using 3 or more extension
sections does not allow proper access
to the valve for service or repair and is
not recommended.
3.3 Installation in Exposed Pipes (Order
Number 84100, 84125, 84150 and 84200)
The Staufix for exposed pipe installati-
on is supplied with a protective cover to
prevent dust and debris of entering the
system and to also help prevent any type
of damage to the system. This protected
cover is not water tight. To remove the
protective cover simple lift both clips on
one side of the cover. Before the black
lower part of the protective hood is dis-
mantled, the feed and drain covers must
be removed.
3.4 Installation in high groundwater/
earth moisture areas
In the case that the Staufix FKA for con-
crete slab installation is to be installed
in a floor slab which will be protected
against groundwater or earth moisture –
sealing gasket set 83075 must be used
(accessory). If the concrete slab will be
equipped with a membrane or sheet
– this sheet is to be connected to the
Staufix FKA body with the counter flan-
ge supplied with the 83075. In the case
that a water proof concrete is being used
then the heavy duty Kautschuk seal (in-
cluded with the 83075) is inserted and
then fixed tight with the counter flan-
ge. Please install the Kautschuk flange
properly so that the pre-drillled holes in
the Kautschuk seal match up with the
screw holes of the counter flange. (see
illustration 7). In the case that the water
tight slab barrier is penetrated by drai-
nage pipes or conduit pipes to the FKA,
it should be assured that these penetra-
tions are also water / moisture tight.The
maximum groundwater resistance of the
Staufix backwater valve for concrete slab
installation is 2 meters.
