General notes

Our systems have to be installed by an
approved sanitary or heating company.

Prior to installation, check the compo­nents 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. 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.

3 Installation

requirements

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.

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.

 Filter element 80 µm
 Operation manual

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 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.

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 per­formed. In order to check the filter for
tightness, the highest pressure admissi­ble must be applied.

7 Inspection /
Maintenance

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.

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.

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.
