A General
1 | Preface
Thank you for choosing a Grünbeck product. Backed by decades of
experience in the area of water treatment, we provide custom-made
solutions for all kind of processes.
Drinking water is classified as food and requires particular care.
Therefore, always ensure the required hygiene in operating and main-
taining systems involved in the drinking water ordinance. This also
applies to the treatment of water for industrial use if repercussions for
the drinking water cannot completely be excluded.
All Grünbeck systems and devices are made of high-quality materials.
This ensures trouble-free operation over many years, provided you
treat your water treatment system with the required care. This opera-
tion manual assists you with important information. Please read the
entire operation manual carefully before installing, operating or servic-
ing the system.
Customer satisfaction is our primary aim, and providing customers
with qualified advice is crucial at Grünbeck. If you have any questions
concerning this system, possible extensions or general water and
waste water treatment, our field service staff, as well as the experts at
our headquarters in Hoechstaedt, are available to help you.
Advice and assistance
For advice and assistance please contact your local representative
(refer to www.gruenbeck.com). In case of emergency, please get in
touch with our service hotline at [phone]. We can connect
you with the appropriate expert more quickly if you provide the re-
quired system data. To ensure that this information is to hand at all
times, please copy the data indicated on the type plate to the table in
chapter C, paragraph 1.
2 | Notes on using the operation manual
This operation manual is intended for operators of our systems. It is
divided into several chapters (a letter is assigned to each of them)
that are listed in the "Table of contents" on page 2 in alphabetical or-
der. Locate the corresponding chapter on page 2 in order to find the
specific information you are looking for.
The headers and page numbers with chapter information make it eas-
ier to find your way around in the operating instructions.

er according to Section 12(2) AVBWasserV (German Ordinance on
General Conditions for the Supply of Water).
3.2 Operating person-
nel Only allow persons who have read and understood this operation
manual to work with the system. Strictly observe the safety infor-
mation.
3.3 Intended use
The system may only be used for the purpose outlined in the product
description (chapter C). The instructions in this operation manual as
well as the applicable local guidelines concerning drinking water pro-
tection, accident prevention and occupational safety must be adhered

3.4 Protection from water damage
Warning! In order to properly protect the installation site from water
damage:
a) a sufficiently dimensioned floor drain system must be available or
b) a safety device (refer to chapter C Optional accessories) must be
installed.
Warning! Floor drains that discharge to a lifting system do not work
in the event of a power failure.
3.5 Indication of
specific dangers
Danger due to electrical energy! →Do not touch electrical parts with
wet hands! Disconnect the system from the mains before starting
work on electrical parts of the system! Have qualified experts replace
damaged cables immediately.
Danger due to mechanical energy! System parts may be subject to
overpressure. Danger of injury and damage to property due to escap-
ing water and unexpected movement of system parts. →Check pres-
sure pipes regularly. Depressurise the system before starting repair
or maintenance work on the system.
Hazardous to health due to contaminated drinking water! →The sys-
tem should be installed by a specialist company only. Strictly adhere
to the operation manual! Ensure that there
is sufficient flow. Adhere to
the pertinent guidelines when starting up the system after extended
periods of standstill. Perform inspections and maintenance at the in-
tervals specified!

Note: By concluding a maintenance contract, you ensure that all of
the required tasks are performed on time. You may perform the inter-
im inspections yourself.
4 | Shipping and storage
Caution! The system may be damaged by frost or high temperatures. In
order to avoid damage of this kind:
Protect from frost during transportation and storage!Do not install or
store the system next to objects which radiate a lot of heat.

B Basic information
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it comes
to the processing of drinking water. This operation manual takes into
consideration the current regulations and stipulates information that
you will need for the safe operation of your water treatment system.
Among other things, the set of rules stipulate that
•only approved companies are permitted to make major modifi-
cations to water supply facilities
•and that tests, inspections and maintenance on installed devic-
es are to be performed at regular intervals.
2 | Water
There is no chemically pure water in nature. Even in the atmos-
phere, rain water absorbs various substances that change the
properties of the water to a greater or lesser degree. This process
continues as the water passes through the ground layers, with the
result that the water is enriched with increasingly large quantities of
materials. Carbon dioxide (CO2) is particularly important here, since
this substance increases the dissolving capability of the water even
more. Consequently, drinking water contains quantities of dissolved
sodium, potassium, calcium, magnesium, iron, manganese, copper,
zinc, chlorides, fluorides, sulphates and also nitrates, nitrites, phos-
phates and silicates that vary greatly from location to location.
Due to dynamic substance and water cycles, harmful elements,
which are only partly and only slowly bi
odegradable are increasingly
released into nature. These are only partially and slowly broken
down by natural effects. Consequently, these elements accumulate
in the groundwater and surface water over the course of time. Re-
moving them from natural water deposits represents a particular
challenge. Grünbeck faces this challenge with the aim of producing
unpolluted drinking and industrial water.
The water works provide us with pure drinking water that is suitable
for consumption. However, if the water is to be used for technical
purposes, further treatment is frequently required.

Fig. B-2: Principle of reverse osmosis system GENO-OSMO-AVRO 125 RU
In the osmosis process, watery solutions of different concentrations
are separated by a semi-permeable membrane. In keeping with the
law of nature, the concentrations will tend to equalise. What is re-
ferred to as "osmotic pressure" is generated on the side of the higher
original concentration. In the reverse osmosis system GENO-OSMO-
AVRO 125 RU, this "osmotic pressure" is countered by a higher pres-
sure. The consequence: The process runs in the opposite direction. A
particular advantage of the reverse osmosis technology compared to
other water treatment processes is the fact that apart from the remov-
al of dissolved salts, bacteria, germs, particles, and dissolved organic
substances are also reduced.
