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.

1.1 Water installa­tion

It is imperative that you comply with certain regulations when in­stalling the GENO-mat MN-Z demanganisation system. Additional
recommendations are given in order to facilitate the handling of the
system. The installation instructions described below are also illus­trated in fig. D-2.

Mandatory regulations

The installation of the GeNO-mat MN-Z demanganisation system
represents a major interference with the drinking water system.
Therefore, only authorised experts may install such systems. 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).

 Observe local and general installation guidelines.

 Provide a drain connection to discharge the backwash water.

 The installation room must have a floor drain (DN 100). If no floor

drain is available, a corresponding water stop device has to be in­stalled.

 Observe the flow direction!

Warning! Floor drains that discharge to a lifting system will not work
in case of a power failure.

Recommendations

 Provide a sampling valve and a pressure gauge directly upstream

and downstream of the GeNO-mat MN-Z demanganisation system
(0 -10 bar). This simplifies the sampling for the regular determina­tion of the iron concentration (functional check).

1.2 Electrical instal­lation

A shock-proof plug is adequate for the electrical connection. How­ever, it must comply with the specifications given in table D-1, may
not be further than 1.20m away from the GeNO-mat MN-Z deman­ganisation system and must carry constant voltage (do not couple
with light switch)!

Caution! Dirt and corrosion particles might damage the system
(control valve). Flush the supply pipe prior to start-up.

2. Establish waste water connection as per DIN EN 1717. Shorten
the rinsing water hose to the length required and direct it to the
drain. Make sure that there is a free outlet (min. 20 mm) to the
drain. Secure the hose with suitable means to prevent the hose
from moving about (exiting regeneration water is pressurised).

Caution! Danger of damage and malfunction due to backflow of
waste water. Therefore, do not bend the hose and do not lead it
higher than the system height.

3. Connect the mains plug to the socket (cf. 1.2).

4. Water the system
In order to prevent the filter material from being washed out, it
must be watered for 24 hours.

E Commissioning

The work described below may only be performed by trained ex­perts. We recommend to have the start-up performed by Grünbeck's
technical service/authorised service company.

Warning! Risk of bacterial growth due to stagnation! According to
VDI 6023, filling the system with drinking water before normal opera­tion commences is prohibited.

The demanganisation system GENO-mat MN-Z must therefore only
first be connected to the drinking water system immediately prior to
commissioning.

1 | How to start up the system

1. Open the valve on the raw water inlet.

2. Open the valve at the pure water outlet.

3. Perform a visual check. Ensure that no water leaks from the sys­tem at any point.

4. Rinse out fine particles
The filter material contains a small amount of fine particles which
must be flushed by means of a backwash prior to start-up. Initiate
a manual regeneration
(refer to chapter F, item 1.4).



Note: The backwash process must be repeated until the backwash
water that flows to the drain in the process step "first filtrate" is clear.

5. Take a water sample at the sampling valve downstream of the
unit.

6. Determine the manganese concentration using the water test kit.

7. Complete the cover sheet and column 1 in the operating log.

2 | Special treatment of the demanganisation system

As GENO-Fermanit is a natural product, it is not possible to rule out
the presence of manganese compounds as MnO, MnO2 or as
Mn2O3. This means that during commissioning, it may occur that the
manganese value is higher downstream of the system than in the in­let water. In this case, a special treatment should be performed.

The special treatment is performed using a kitchen salt solution
(NaCI).

 Fill the regeneration unit (optional accessory, see chapter C, point

5) with saturated brine
(For quantities, see Table E-1).

 Performing a special treatment

(For procedure, see chapter G, point 3).

Then perform a regeneration process with GENO special granulate
or
GENO-oxi plus (see chapter G, point 3.1).

Required brine volume [l]

15 30 40 66 88 130 221

Caution! Special treatment only following consultation with the fac­tory, or carried out by Grünbeck's technical service/authorised ser­vice company.

2.1 Continuous addition of GENO-oxi plus

Caution! The following instructions only apply when using the in-

tended system components (see chapter C, point 5).
When using other system components (a different GENODOS pump
or water meter), a special design is required (factory/sales depart­ment).

Installation in accordance with the installation drawing (see chapter
D, point 3, fig. D-2).

Following commissioning of the demanganisation system, the con­tinuous addition of GENO-oxi plus should be carried out initially for
around 6 weeks. The stroke length of the GENODOS pump should
be set to 80%. After the run-in time, the stroke length can be re­duced each week by 10 % until manganese breaks through (but to a
maximum of 30%). This means that the limit value has been
reached. Finally, increase the stroke length for subsequent operation
by 10%.

F Operation

1 | How to operate the control unit

The control unit regulates the operating processes of the demangan­isation system.

1.1 How to set the
time

GENO-mat MN-Z demanganisation systems are factory-set so that
the automatic backwash is started at 2am each day (during the
night). Set the current time during commissioning or after a power
failure.

1. Loosen the screw on the housing cover (top right).

2. Open the housing cover.

3. Press and hold the red button (fig. F-1, pos. 6).

4. Turn the 24 hour disk until the reference arrow (fig. F-1, pos. 2)
points to the current time.

5. Release the red button (fig. F1, pos. 6).



Note: If the preset time for the backwash (2:00 am) is unfavourable
for internal reasons, set a time which deviates from the current time
on the 24 hour disk to adjust the starting time for the backwash.

Example:
Desired starting time of the backwash: 22:00
 Move clock forward 4 hours.

1.2 How to set the
backwash interval

The maximum backwash interval is 12 days. Furthermore, an auto­matic backwash can be carried out after 6, 4, 3, 2 or 1 day(s) (fac­tors of 12). Fig. F-1 indicates the setting for a backwash to be car­ried out every 2 days.

1. Determination of the backwash interval.

 For hygienic reasons, a backwash should be carried out every 6

days (factory-setting).

 If the differential pressure of the filter is > 0.3 bar above normal af-

ter 6 days due to a higher concentration of dirt in the water, a
backwash process should be initiated every 4 days or at even
shorter intervals.

 The same applies in case of an early breakthrough of dirt parti-

cles.

2. Push the switching pin (fig. F-1, pos. 5) outwards for the 1st day.

3. Set the other switching pins as required.
On all days where the switching pins are pushed outwards, the
backwash is initiated. In order to set, for example, a backwash in­terval of 3 days, the switching pins in positions 1, 4, 7 and 10 on
the day disk must be pushed outwards (fig. F-1, pos. 4).

1.3 How to read the
operating state

The current operating state may be read from the position of the ref­erence point (fig. F-1, pos. 8) on the backwash wheel (fig. F-1, pos.

1).

The reference point
(fig. F-1, pos. 8) lies op­posite the reference arrow
(fig. F-1, pos. 7).

Operating mode: pure water is available.

Backwash; the backwash wheel (fig. F-1,
pos. 1) turns clockwise; the progress of
the backwash can be read from the posi­tion of the reference point (fig. F-1,
pos. 8).

The day disk (fig. F-1, pos. 4) turns counter-clockwise once in
12 days. The red reference arrow (fig. F-1, pos. 3) points to the posi­tion where a switching pin turned outwards initiates a backwash. In
the operating mode, the distance between the reference arrow
(fig. F-1, pos. 3) and the following switching pin which is turned out­wards is an indication for the number of days until the next back­wash.

1.4 How to initiate a
manual backwash

Manual regeneration should be initiated if

 the differential pressure of the demanganisation system is more

than 0.3 bar above normal before the timer control initiates the
backwash.

 the systems are restarted after longer periods of standstill.

 maintenance or repair work has been carried out.

Irrespective of the set backwash interval and the time, the backwash
can be initiated manually at any time.

1. Check the operating status.

Only in operating mode:

2. Turn backwash wheel (fig. F-1, pos. 1) to the right by one catch
(note the click!).

The demanganisation system starts the backwash process, the
backwash wheel (fig. F-1, pos. 1) slowly turns clockwise. After ap­prox. 3 hours, the backwash is terminated and the white reference
point (fig. F-1, pos. 8) is located opposite of the black reference ar­row for the current time again (fig. F-1, pos. 7).

G Maintenance and care

1 | Basic information

To guarantee the reliable function of the GENO-mat MN-Z deman­ganisation systems over a long period of time, some maintenance
work must be performed at regular intervals. This applies in particu­lar to the backwash in the drinking water sector where the required
measures are defined in the pertinent regulations and guidelines. All
regulations and guidelines which apply at the installation site must
be strictly adhered to.

DIN EN 806-5 stipulates:

 Inspection every 2 months

 Maintenance every 6 months

 The maintenance work has to be performed by the Grünbeck’s

technical service/authorised service company or by an authorised
specialist company.

 An operation log must be kept in order to document the mainte-

nance work performed.



Note: By concluding a maintenance contract you ensure that all
maintenance work will be performed in due time.

The operation log is attached to this operation manual.

2 | Inspection (functional check)

You may perform the regular inspections yourself.

Overview: Inspection work

 Determine inlet water (manganese, iron).

(Water test kit)

 Determine pure water (manganese, iron).

(Water test kit)

 Differential pressure of the system

 Check control unit settings:

a) Time
b) Test raw water hardness



Note: Minor deviations are normal and cannot be prevented techni­cally. If you detect major deviations, please notify Grünbeck’s tech­nical service/authorised service company.

 Check the entire system for outward tightness.

 Check control valve to drain for tightness (in operating mode).

3 | Maintenance

Maintenance work on the GENO-mat MN-Z demanganisation sys­tems may only be performed by Grünbeck’s technical service/au­thorised service company or by an approved specialist.

An operation log must be kept for GeNO-mat MN-Z demanganisa­tion systems. In this operation log, the customer service technician
records all maintenance and repair work performed. In case of mal­functions, this log helps to identify possible sources of error. In addi­tion, the log documents the proper system maintenance.

Make sure that all maintenance work is recorded in the opera­tion log.

Overview: Maintenance work

 Read water pressure, flow pressure and if necessary water meter

reading.

 Determine iron concentrations.

 Check initiation of backwash.

 Check control valve for tightness, replace wearing seals if neces-

sary, check the proper function of the drive motor of the control
valve, clean injector and sieve.

 "Regenerate/disinfect" system.

 Check the level of the filter material in the filter tank. Refill filter

material, if required.

3.1 Regeneration/disinfection of GENO-mat MN-Z demanganisation systems



Note: We recommend to have the regeneration/disinfection per­formed by Grünbeck’s authorised technical service/authorised ser­vice company.

3.1.1 Oxidant
Designated area of application:

Oxidizing agents are used for the regeneration and disinfection of
deferrisation and demanganisation systems; they are also dosed up­stream of deferrisation and demanganisation systems in order to
completely oxidise iron II and manganese II compounds.

The dosing and the dosing volumes depend on the iron and manga­nese concentrations contained in the raw water.

You can use either our GENO special granulate1) or
GENO-oxi plus (liquid).

3.1.2 Preparing the regeneration agent

 Fill the regeneration tank with filtered water (for respective quanti-

ties refer to Table G-1). We recommend installing a filling tap in the
pure water pipe for this purpose.

 Pour the GENO special granulate1) or GENO-oxi plus into the tank

and mix using the integrated hand mixer until the special granulate
has dissolved completely.

 Install a suction hose between the regeneration tank and the ball

valve at the control valve.
