General notes
Our systems have to be installed by an
approved sanitary or heating company.
Prior to installation, check the compo-
nents for shipping damage.
The devices must be protected against
frost and must not be installed near heat
sources which radiate a lot of heat.
Attention
: Do not clean the filter with
cleaning agents that contain alcohol or
solvents!
In case of drinking water that contains a
lot of coarse dirt, a coarse filter must be
installed upstream.
1 Application
The FS-B filters are designed for the
filtration of drinking water. The filters are
not suited for circulation water that has
been treated with chemicals. Further-
more, it is neither suited for oils, greas-
es, solvents, soaps and other lubricating
media nor for the separation of water-
soluble materials. The filters may be
used in the pressure and negative pres-
sure range.

3 Installation
requirements
Please observe local installation guidelines
and general regulations as well as tech-
nical specifications.
The installation site must be frost-proof
and must ensure the protection of the
filter against chemicals, dyes, solvents,
vapours and direct sunlight.
Observe flow direction (
indicated on
the housing)! Install voltage-free. The
installation site must be frost-proof.
The filter should be installed in equally
dimensioned pipes according to its
nominal diameter.
4 Scope of
delivery
Filter with protective cover and built-
in maintenance indicator.
Screw connections with seals made
of LD-PE.

5 Installation
As per DIN EN 806-2 and DIN 1988-200
the FS-B filter has to be installed in the
cold water pipe downstream of the water
meter and upstream of the distribution
pipes respectively upstream of the de-
vices to be protected. Install shut-off
valves upstream and downstream of the
filter (refer to fig. 1). The filter is suited
for horizontal installation only.

6 Start-up
After completion of the installation, put
the filter into operation by opening the
shut-off valves. Then de-aerate the
piping via the nearest screw connection.
Leakage test
A leakage test must be performed on the
filter directly after installation and after
each time maintenance work was per-
formed. In order to check the filter for
tightness, the highest pressure admissi-
ble must be applied.
7 Inspection /
Maintenance
According to the DIN Standard EN 806-
5, the operator must
inspect
the filters
every two months (functional inspection).
During the inspection, the filter element
must be checked for contamination and
be replaced, if necessary (contamination
and/or increased differential pressure).
Check for tightness.
Furthermore,
maintenance
has to be
performed by the operator or the installa-
tion company every six months.
Warning!
According to DIN EN 806-5
the filter element must be replaced for
hygienic reasons every 6 months. Fur-
thermore, we recommend replacing the
seal of the protective cylinder every 2
years using a set of seals.

How to proceed
Place a bucket beneath the filter.
Close the shut-off valves.
Depressurize the pipe.
Manually unscrew the filter cylinder.
Remove the dirty filter element from
the supporting fabric and replace by
new filter element. For hygienic rea-
sons, do not touch the new filter ele-
ment with bare hands.
Hygienic filter replacement:
Open the foil and push the filter ele-
ment including the foil over the support-
ing fabric, pull off the foil without touch-
ing the filter element. (see fig. 3)
Check that the sealing surfaces as
well as the O-ring are clean and
manually screw on the filter cylinder
to the stop.
Start up as described in point 6.
