2. Purpose
2.1 Filtration
The product is used to filter drinking water in ac-
cordance with the World Health Organization. The
water pipes and the connected fittings, devices,
works equipment, boiler systems, boilers and pro-
duction systems are protected against malfunctio-
ning and corrosion damage caused by impurities.
Note: Following specialist advice, the product can
also be used to filter non-potable water such as well,
process, boiler feed, cooling and air conditioning
water. It is essential to obtain specialist advice.
The product is not suitable for oils, greases, solvents,
soaps and other lubricating media. Water-soluble
substances cannot be precipitated out either.
2.2 Pressure reducer (only E1 NEU HWS)
The integrated pressure reducer installed down-
stream from the filter serves to reduce pressure
and regulate a desired back pressure, predomi-
nantly in the domestic water supply plant. It keeps
the regulated back pressure almost constant, even
when the pre-pressure fluctuates between, for ex-
ample, 16 bar and the set back pressure, e.g. 3 bar.
A uniform, not too high pressure preserves fittings
and devices in the entire domestic water installati-
on, helps to save up to 50 % of water and minimises
noise evolution. We recommend the installation of
a pressure reducer from 4 bar pre-pressure.
Caution: The plant must be set up according to
the installation and operating instructions of the
AVB Water V, Sec. 12.2. by the water supply com-
pany or an installation company entered into the
installer directory of a water supply company.
3. Function
3.1 Filtration
The raw water flows through the raw water inlet
into the filter and then from the outside to the in-
side through the filter element to the pure water
outlet. The foreign particles larger than the filter ra-
ting are retained on the outside of the filter fabric.
Clean water enters into the pipeline system.
If as a result of the increasing contamination of
the filter fabric the water pressure decreases per-
ceptibly, the filter element must be replaced. BUT
AFTER 6 MONTHS AT THE LATEST!
3.2 Pressure r backflow preventer (only
E1 NEU HWS)
The pressure reducer works according to the prin-
ciple of the relieved single-seat valve. It is cont-
rolled starting from the back pressure via a large-
dimensioned membrane and a pressure spring, the
tension and thus the back pressure of which can be
changed with the rotary knob (10). The display (5)
shows the respective back pressure setting value.
The backflow preventer only opens in the direction
of flow when water is removed and is tightly sealed
in idle position or counterpressure.
