2 Safety
2.1 Safety measures
●Only operate your product if all components are installed
properly.
●Adhere to the applicable local guidelines on drinking water
protection, accident prevention and occupational safety.
●Do not make any changes, alterations or extensions on your
product. Only use genuine spare parts for maintenance or re-
pair.
●Keep the premises locked to prevent unauthorised access
and to protect endangered/non-instructed people from resid-
ual risks.
●Observe the maintenance intervals (refer to chapter 8.2). Fail-
ure to comply can result in microbiological contamination of
your drinking water system.
2.1.1 Hazards relating to pressure
●Components can be under pressure. There is a risk of injuries
and damage to property due to escaping water and unex-
pected movement of components. Check the pressure lines
and the product for leaks at regular intervals.
●Before starting repair and maintenance work, make sure that
all affected components are depressurised.

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 pureliQ:RD with pressure reducer in addition is
suitable for the adjustment of the outlet pressure on the with-
drawal side in order to maintain the max. admissible operating
pressure stipulated in DIN EN 806-2. The backwash and the
adjustment of the after-pressure on the withdrawal side, how-
ever, only works when applied in the positive pressure range.
●The filters can be used for positive pressure and negative
pressure applications.
●The filters are designed according to the stipulations of
DIN EN 13443-1 and DIN 19628 and are intended for installa-
tion into the drinking water system according to DIN EN 806-2
(installation immediately downstream of the water meter).
●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.
3.1.1 Foreseeable misuse
●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.

3.3 Functional description
The unfiltered drinking water flows into the filter through the inlet
side and from the outside in through the filter element and to the
pure water outlet. Thus, foreign particles of a size > 100 µm are re-
tained.
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 ele-
ment and then flows through the filter element in reverse direction of
standard filtration. Thanks to Grünbeck’s innovative Vortex technol-
ogy, particles sticking to the filter element are detached and washed
out to the drain.
In the backwash filter pureliQ:RD, the flow-optimised pressure re-
ducer, which is designed according to DIN EN 1567, additionally en-
ables the outlet pressure on the withdrawal side to be set to
1 –6 bar (factory setting: 4 bar).
