1 Top section in brass
2 Connection thread with reduction fittings
3 Transparent cylinder with filter element
4 Hose connection for flushing water supply
5 Turning knob for the backwashing element
Application
This filter is intended for the filtration of drinking
and service water. It protects the water pipes and
the connected water system parts from malfunc-
tions and corrosion damage due to impurities such
as rust particles, chippings, sand, hemp, etc.
The filter cannot be used in applications with
chemically treated circulating water, process water
and cooling water for continuous cooling systems.
In applications with water containing coarse im-
purities, a coarse dirt separator must be used.
The filter is not suitable for oils, greases, sol-
vents, soaps and other lubricating media nor for
the separation of water-soluble substances.
Attention: In accordance with AVB Wasser V,
§ 12.2, the installation of the equipment may
only be carried out by the public water sup-
ply company or by an installation company
listed in the installer directory of a water sup-
ply company.
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 filter
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 suc-
tion and then washed out.

Installation conditions
Observe the local installation regulations, gen-
eral 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 protected
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
grease, solvents and acidic as well as basic
detergents. The plastic parts must be re-
placed even if there is no visible damage af-
ter severe concussions and shocks e.g. due
to the use of unsuitable tools or if dropped
on stone floors etc (danger of bursting).
Avoid extreme pressure impact.

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 direction
arrow) in the horizontal cold water pipe (see in-
stallation 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 1988, the flushing
water hose must be installed at a minimum dis-
tance of 20mm to the highest possible waste wa-
ter level (free discharge).
Startup
Check the filter and the flushing water pipe for
proper installation.
The stop valves must not be opened yet. Check
the transparent cylinder (3) for proper fit and then
close the turning knob (5) by turning it clockwise.
