to the system or other objects.
Note: This symbol emphasises information and tips that facilitate
your work.
Tasks with this symbol may only be performed by Grünbeck's technical service/authorised service company or by persons expressly
authorised by Grünbeck.
Tasks with this symbol may only be performed by trained and qualified electrical experts according to the VDE guidelines or according
to the guidelines of a similar local institution.
Tasks with this symbol may only be performed by water suppliers or
approved installation companies. In Germany, the installation company must be registered in a water company installation directory as
per §12(2) AVBWasserV (German Ordinance on General Conditions
for the Supply of Water).
3.2 Operating personnel
Only allow persons who have read and understood this operation

3.3 Intended use
The system may only be used for the purpose outlined in the product
description (chapter C). The guidelines in this operation manual as
well as the applicable local guidelines concerning drinking water protection, accident prevention and occupational safety must be observed.
In addition, intended use also implies that the system may only be
operated when it is in proper working order.
Any errors must be eliminated at once.
3.4 Protection from
water damage
Warning! To properly protect the installation site from water dam-
age:
a) a sufficient floor drain system must be available or
b) a water stop device (see chapter C Accessories) must be in-
stalled.
Warning! Floor drains that discharge to a lifting system will not work
in case of a power failure.
3.5 Indication of
specific dangers
Danger due to electrical energy! Do not touch electrical components with wet hands! Disconnect the system from the mains before
starting work on electrical system components! Have qualified experts replace damaged cables immediately.
Danger due to mechanical energy! System components can be subject to overpressure. Risk of injuries and damage to property due to
escaping water and unexpected movement of system parts.
Check pressure pipes regularly. Depressurise the system before
starting repair or maintenance work on the system.
Hazardous to health due to contaminated drinking water! The
system should be installed by a specialist company only. Strictly adhere to the operation manual! Ensure that there is sufficient flow,
and observe the relevant guidelines when starting up the system after extended periods of standstill. Perform inspections and maintenance at the intervals specified!
Note: By concluding a maintenance contract, you ensure that all of
the required tasks are performed on time. The intermediate inspections can be performed in-house.

4 | Shipping and storage
Caution! The system can be damaged by frost or high tempera-
tures. In order to avoid damage of this kind:
Protect from frost during transportation and storage!
Do not install or store system next to objects which radiate a lot of
heat.
The system may only be transported and stored in its original pack-
ing. Ensure that it is treated with care and placed the right side up
(as indicated on the packaging).
5 | Disposal of used parts and consumables
Used parts and consumables should be disposed of or made available for recycling purposes according to the applicable local guidelines.
If consumables are subject to specific determination, observe the
corresponding instructions on the packaging.
If in doubt, contact your local waste disposal authority or the manufacturer for more information.

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 demanganisation system.
Among other things, the set of rules stipulates that:
only approved companies are permitted to make major modifica-
tions to water supply facilities
and that tests, inspections and maintenance on installed devices
are to be performed at regular intervals.
2 | Designated application/area of application
The GENO-mat MN-Z demanganisation systems are designed for
the reduction of iron and/or manganese. They are used in the residential sector for private water supply plants with maximum values
of up to 3.0 mg/l of iron and 1.0 mg/l of manganese. If the systems
are operated properly and handled according to the operation manual, pure water values as required by the German Drinking Water
Ordinance (TrinkwV) can be achieved.
For an optimum reduction of iron and manganese, a pH value > 7.2
is required. A dosing system for oxidants has to be provided upstream of the demanganisation system.
However, should ammonium (> 0.1 mg/l) be detected in the raw water, an additional treatment step is required.
3 | Function
The demanganisation system GENO-mat MN-Z is operated with the
natural, catalytic filter material Fermanit. A central control valve automatically controls the operating cycles filtration - backwash - and first
filtrate.

3.1 Filters
The raw water flows into the filter tank via the raw water inlet and
then, from top to bottom, through the catalytic filter material. By
means of an oxidation process, dissolved iron and manganese salts
are transformed into insoluble oxides and are deposited on the Fermanit material.
In this oxidation process, the Fermanit releases electrons to the iron
and manganese until the supply is exhausted. The electrons have to
be replaced continuously by dosing GENO-oxi plus (refer to product
data sheet).
By dosing oxidants, the oxidation and precipitation of iron and manganese already takes place prior to their contact with the Fermanit
material. Thanks to its catalytic properties a complete oxidation and
due to the excellent filtration characteristics, an optimum filtration are
achieved. The filtered pure water is then directed via the lower distributing nozzle and the riser pipe through the pure water outlet into
the piping system.
3.2 Backwashing
During the backwash process, the filter bed is forcibly flushed from
bottom to top and thus loosened up. Impurities retained during the
filtration process are washed out via the drain outlet at the control
valve. The demanganisation system must be backwashed every 6
days at the latest (for the setting refer to chapter F).
3.3 First filtrate
By an automatic switch-over of the central control valve, the filter
bed will forcibly be flushed from top to bottom. This first filtrate is discharged to the drain and afterwards, the demanganisation system
GNEO-mat MN-Z is ready for operation once again.
3.4 Regeneration/disinfection
For operating and hygienic reasons, the demanganisation system
must be regenerated every 6 months with GENO special granulate
or GENO-oxi plus.
3.5 Control unit
The demanganisation system GENO-mat MN-Z is time-controlled
via an electrical timer.
In order to properly use the automatic timer control, the time interval
between two filter sequences (backwash interval in days) must be
set.

2 | Technical specifications
The GeNO-mat MN-Z demanganisation system is a single system
with integrated bypass for the supply of raw water during the backwash process. It is equipped with a timer control. The backwash is
initiated after a set time interval.
All system data is summarised in table C-1. The data refers to the
standard versions of the GeNO-mat MN-Z demanganisation system.
Possible deviations in case of special versions are communicated
separately, if applicable.
Caution! Electrically operated valves. In case of a power failure during the backwash, water may enter the drain. In the event of power
failure, check the system and shut-off the water supply, if necessary.
