2. Application

The product is used to filter drinking water in
accordance with the World Health Organization.
The water pipes and the connected fittings, de-
vices, works equipment, boiler systems, boilers
and production systems are protected against
malfunctioning and corrosion damage caused by
impurities.
Note: Following specialist advice, the product can
also be used to filter non-potable water such as
well, process, boiler feed, cooling and air con-
ditioning water. It is essential to obtain specialist
advice.
The product is not suitable for oils, greases, sol-
vents, soaps and other lubricating media. Water
soluble substances cannot be precipitated out
either.
Attention: In accordance with AVB Wasser V, §
12.2, the installation of the equipment may only
be carried out by the public water supply com-
pany or by an installation company listed in the
installer directory of a water supply company.

3. Function

The untreated water flows through the untreated
water inlet into the filter and from there from the
inside to the outside through the filter element
into the clean water outlet. Any impurities >90 μm
are trapped on the inside of the filter cloth. The fil-
ter element needs to be cleaned by backwashing
at regular intervals.
For the backwashing process, the waste water
connection is opened by turning the turning knob
and the backwashing element is also turned. The
particles on the filter cloth are removed by suction
and then washed out.

4. Installation conditions

Observe the local installation regulations, general
guidelines, general hygiene regulations and the
technical specifications.
A connection to the sewage system (discharge) of
min. DN 40 should be available.
Attention: The installation site must be protec-
ted against frost and must ensure the protection
of the filter against e.g. solvent vapours, fuel oil,
lees, chemicals of any kind, UV radiation and
heat sources above 40 °C.
Attention: keep the plastic parts free from gre-
ase, solvents and acidic as well as basic deter-
gents. The plastic parts must be replaced even
if there is no visible damage after severe concus-
sions and shocks e.g. due to the use of unsuitab-
le tools or if dropped on stone floors etc (danger
of bursting). Avoid extreme pressure impact.

5. Installation

Install filter according to its nominal width in cold
water pipes of the same dimensions and before
the equipment to be protected. Install stop valves
before and after the filter.
Assemble the connection fittings (2) in the pipe
and install filter in flow direction (see flow direc-
tion arrow) in the horizontal cold water pipe (see
installation sketch).
Route the flushing water connection with hose to
the sewage channel or provide a collection basin
(capacity approx. 10 l).
Please note: According to DIN EN 806-5, the
flushing water hose must be installed at a mini-
mum distance of 20 mm to the highest possible
