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

3.3 Functional description
The unfiltered drinking water flows into the filter from the inlet side
and then 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.
The controller automatically releases the backwash as per the
setting. Possible settings for the backwash intervals are 7, 30, 60
and 90 days. A backwash can be initiated manually at any time.
The drain is opened by triggering a backwash. The water flows
through the primary screen to the filter element and then flows
through the filter element in reverse direction of standard filtration.
Particles adhering to the filter element are freed and rinsed out to
the drain.
The backwash process takes about 50 seconds. In case some
particles still remain on the filter element, the backwash must be
triggered again manually. Grünbeck recommends a backwash
interval of 60 days.
In the automatic filter pureliQ:AD, the flow-optimised pressure
reducer, which is designed according to DIN EN 1567, enables
the after-pressure 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 in relation to 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.
The installation location must be away from heat sources (e.g.
washing machines, boilers and hot water pipes).
A drain connection DN 50 must be available to discharge the
flushing water.
There must be push socket with earthing contact in the
installation area.
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.
4.3.1 Installing the filter
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.
The rotatable click-type connection flange allows the filter to be
adapted to any flow direction given on site.

Installation
20 | 44
BA_TD3-AA000en_025
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.
