Our systems have to be installed by an
approved sanitary or heating company.
Observe flow direction ( indicated on
the housing)! Install voltage-free. The
installation site must be frost-proof.
Prior to installation, check the components for shipping damage.
The filter should be installed in equally
dimensioned pipes according to its
nominal diameter.
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!
4 Scope of
delivery
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. Furthermore, it is neither suited for oils, greases, solvents, soaps and other lubricating
media nor for the separation of watersoluble materials. The filters may be
used in the pressure and negative pressure range.
6 Start-up
5 Installation
 Filter with protective cover and builtin maintenance indicator.
 Screw connections with seals made
of LD-PE.
 Filter element 80 µm
 Operation manual
Leakage test
A leakage test must be performed on the
filter directly after installation and after
each time maintenance work was performed. In order to check the filter for
tightness, the highest pressure admissible must be applied.
7 Inspection /
Maintenance
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 devices 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.
Warning! According to DIN EN 806-5
the filter element must be replaced for
hygienic reasons every 6 months. Furthermore, we recommend replacing the
seal of the protective cylinder every 2
years using a set of seals.

Please observe local installation guidelines
and general regulations as well as technical specifications.
The installation site must be frost-proof
and must ensure the protection of the
filter against chemicals, dyes, solvents,
vapours and direct sunlight.

According to the DIN Standard EN 8065, 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 installation company every six months.
2 Technical specifications
Fine filter
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.

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 reasons, do not touch the new filter element with bare hands.
Hygienic filter replacement:
Open the foil and push the filter element including the foil over the supporting fabric, pull off the foil without touching 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.
