3 Product description
3.1 Intended use
●The backwash filters pureliQ:R and pureliQ:RD are
designed for the filtration of drinking water.
●The backwash filter pureliQ:RD with pressure reducer in
addition is suitable for the adjustment of the holding
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.
●They are neither suitable for oils, greases, solvents, soaps
and other lubricating media, nor for the separation of water-
soluble substances.
●The backwash filters pureliQ:R und pureliQ:RD are
designed according to DIN EN 13443-1, DIN 19628 and
DIN EN 1567 (only applies to the backwash filter
pureliQ:RD) 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 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.
By turning the backwash handwheel to the stop position, the drain
is opened. The water flows through the primary screen to the filter
element and then flows through the filter element in reverse
direction of standard filtration. Thanks to Grünbeck’s innovative
Vortex technology, particles sticking to the filter element are
detached and washed out to the drain.
The backwash process should be carried out for approx. 5 - 10
seconds. In case some particles still remain on the filter element,
the backwash has to be repeated. Grünbeck recommends
performing a backwash every two months.
In the backwash filter pureliQ:RD, 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 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.
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.
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.
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).

4.3.2 Attaching the backwash connection
Discharge of backwash water with drain and trap
►Install the drain connection (not included in the scope of
supply) at the lower outlet of the filter.
The supplied hose adapter is not required for this variant.
The free outlet is already integrated in the filter for this variant.
