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.
The pressure reducing valve keeps the adjusted
back pressure almost constant, even if the supply
pressure fluctuates. A uniform and not excessively
high pressure is less harmful to the valves and
equipment of the entire domestic water installation.
Installation conditions
Observe the local installation regulations, general
guidelines, general hygiene regulations and the
technical specifications.
The sewage system (discharge) must be min.
DN 40. The waste water connection of the filter is
DN 50.
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 replaced
even if there is no visible damage after 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.

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 chemi-
cally 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.
