3 Product description
3.1 Intended use
● The fine filters pureliQ:K and pureliQ:KD are designed for
the filtration of drinking water.
● The fine filter pureliQ:KD with pressure reducer in addition
is suitable for the adjustment of the holding on the
withdrawal side.
● The filters can be used for positive pressure and negative
pressure applications. The adjustment of the after-pressure
on the withdrawal side, however, only works when applied
in the positive pressure range.
● The filters are not suitable for circulation water that is
treated with chemicals.
● They are neither suitable for oils, greases, solvents, soaps
and other lubricating media, nor for the separation of watersoluble substances.
● The fine filters pureliQ:K and pureliQ:KD are designed
according to DIN EN 13443-1, DIN 19628 and
DIN EN 1567 (only applies to the fine filter pureliQ:KD) and
are intended for installation in drinking water systems
according to DIN EN 806-2 (installation directly after the
water meter system).
● They protect the water pipes and connected water-carrying
system parts from disturbances and corrosion damage due
to undissolved impurities (particles) such as rust particles,
sand, etc.

3.3 Functional description
The unfiltered drinking water flows into the filter from the inlet side
and then flows from the outside in through the filter element and
to the pure water outlet. Thus, foreign particles of > 100 µm in
size are retained.
Depending on their size and weight, the foreign particles either
stick to the filter element or they fall straight down into the filter
cylinder.
In the fine filter pureliQ:KD, the flow-optimised pressure reducer,
which is designed according to DIN EN 1567, enables the afterpressure on the withdrawal side to be set to 1 – 6 bar (factory
setting: 4 bar).

4 Installation
The installation of a filter represents a major intervention into the
drinking water system and may only be performed by a
specialist installer.
The pureliQ filters are installed in accordance with DIN EN 806-2
and DIN 1988-200 in the cold water line downstream of the water
meter and upstream of distribution lines or the devices to be
protected.

4.1 Requirements for the installation site
Observe local installation directives, general guidelines and
technical specifications. The installation site must be frost-proof
and ensure the filter's protection from chemicals, dyes, solvents,
vapours and direct sunlight.
Installation
17 | 44
-AK000
en_035
The installation location must be away from heat sources (e.g.
washing machines, boilers and hot water pipes).
The installation room must be provided with a floor drain. If none
is available, an appropriate safety device has to be installed to
avoid water damage. We recommend using a protectliQ:A.
The installation site must be well accessible for maintenance
purposes.

4.3 Installing the product
In order for the water line on both sides of the filter to be
properly connected to the protective-equipotential bonding, we
recommend establishing a corresponding electrical bypass
according to DIN VDE 0100-540.
Use suitable tools for assembly and be careful not to scratch the
housing with your tool.
The transparent plastic film serves as transport and dirt
protection. We recommend leaving it on the device during
assembly and the construction phase to prevent soiling of the
white housing.
1. Install the water meter screw connection in the pipe (the
distance between the two seals must be 100 mm).
2. Leave the protective caps on the threads.
Installation
19 | 44
-AK000
en_035
The rotatable click-type connection flange allows the filter to be
adapted to any flow direction given on site.
3. Check the flow direction given on site
4. Rotate the click-type connection flange to the position
suitable for your flow direction (marking on click-type
connection flange).
5. Remove the protective caps.
6. Install the filter without stress and tighten the union nuts.
» This completes the installation.

10 Other information
10.1 Explanation of terminology
Filter element
Part of the filter that ensures the retention of the particles.
Pore size
The filter's ability to retain particles and suspended matter of
a certain size range, regardless of the type of filter material.
It is defined by the upper and lower filtration fineness
Nominal flow
Flow rate at which, with a clean filter, either the pressure
loss does not exceed 50 kPa (0.5 bar) or the filter surface
loading does not exceed the maximum specified value
(whichever value is lower)
Upper filtration fineness
the number indicates the particle size of a material in μm
which passes through the filter under test conditions with a
mass fraction of 10%
Drinking water
Drinking water is any water that is intended to be used in the
domestic environment for drinking and all other food
preparation purposes, for personal hygiene and cleaning as
well as for cleaning objects that do not only temporarily
come into contact with foodstuffs or the human body.
