on the valve should remain clean and 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. If tiles will be placed into the re-
cessed cover it is important that the proper
adhesive material is used and the follo-
wing instructions are followed:
Tiles
a)The inner surface of the recessed cover
should be coated with a bonding mate-
rial which sticks to ABS (such as PCI
base coat 303). After this surface coat
has properly dried the tile surface can
now be laid into the recessed upper
section by using a silicon adhesive. This
method is ideal for thinner tiles since the
remaining height can be built up with
the tile mortar.
b)Installing tiles with PCI-Silcoferm S (self
adhering silicone). This method is ideal
for thicker tiles since a thinner adhesive
surface is used.
Tiling with natural stone such as gra-
nite, marble or agglomarmor
a)The inner surface of the recessed cover
should be coated with a boding materi-
al which sticks to ABS (such as PCI base
coat 303). The natural stone surface can
then be laid into the covers using an ap-
propriate adhesive (for example PCI-
Carralit)
b)Installing a natural stone surface a with
a special silicon such as PCI-Carraferm.
Follow the same instructions as in the
Tiles' section above.
3.2 Extended Depth Installation (Part Order
Number 83071)
If the Staufix® SWA is to be installed in an
high groundwater or high earth moisture
area then the instructions in Section 2.4
must be followed. Depending on the re-
quired depth of installation, either one or
two of the KESSEL extension sections can
be used. Connection gaskets are supplied
with the 83071 and should be properly lu-
bricated as stated previously. In order to
reach the properly installation height when
using extension section(s) it may be re-
quired to shorted the top upper section.
Caution!
Using 3 or more extension sections
does not allow proper access to the
21
valve for service or repair and is not re-
commended.
3.3 Installation in Exposed Pipes
(Order Number 83100, 83125, 83150 and
83200) The Staufix® for exposed pipe in-
stallation is supplied with a protective
cover to prevent dust and debris of ente-
ring the system and to also help prevent
any type of damage to the system. This
protected cover is not water tight. To re-
move the protective cover simple lift both
clips on one side of the cover. Before the
black lower part of the protective hood is
dismantled, 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 83023 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 flange sup-
plied with the 83023. In the case that a
water proof concrete is being used then
the heavy duty Kautschuk seal (included
with the 83023) is inserted and then fixed
tight with the counter flange. Please in-
stall 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 pe-
netrated by drainage pipes or conduit
pipes to the SWA, it should be assured
that these penetrations are also water /
moisture tight.
The maximum groundwater resistance of
the Staufix® backwater valve for concre-
te slab installation is 2 meters.
