2.1 Safety measures
●Obey the local regulations on accident prevention and occu-
pational safety.
●Obey the following regulations on the treatment and dis-
charge of condensate originating from condensing boilers into
the public sewer system:
•Work sheet DWA-A 251:2011 "Condensates from con-
densing boilers"
•DVGW VP 114 „Neutralisation systems for gas firing sys-
tems; requirements and testing“

However, a neutralisation is nevertheless required:
1) If the domestic waste water is discharged into small sewage treatment plants,
2) in case of buildings and lots whose drainpipes do not meet the material
requirements stipulated in paragraph 5.3,
3) in case of buildings which do not meet the requirements for adequate mixing
as per paragraph 4.1.1.

Safety

●Only operate your product if all components are installed
properly.
●Do not make any changes, alterations or extensions on your
product.
●Only use genuine spare parts for maintenance or repair.
●Keep the premises locked against unauthorised access to
protect imperilled or untrained persons from residual risks.
●Comply with the maintenance intervals (refer to chapter 8.2).
2.1.2 Mechanical hazards
●You must never remove, bridge, or otherwise tamper with
safety equipment.
●Make sure that the product is set up in a way that it cannot tip
over and that stability is guaranteed at all times.
2.1.3 Danger due to condensate
●Non-neutralised condensate is acidic and can cause chemical
burns and irritation when coming into contact with the skin or
the eyes.
●Avoid any skin/eye contact with the condensate.
●Use personal protective equipment when working with con-
densate.
●The condensate may damage surfaces when covering them.

Safety

Cleaning/Disposal
●Immediately absorb leaked and non-neutralised condensate
with disposable towels.
●Dispose of the absorbed condensate with residual waste in an
environmentally sound manner.
2.1.4 Groups of persons requiring protection
●This product is not designed to be used by persons (including
children) with reduced capabilities, lack of experience or lack
of knowledge.
●Children should be supervised to make sure that they do not
play with the product.
2.1.5 Neutralisation granulate (GENO-Neutralit Hz)
●The neutralisation granulate is not considered to be a danger-
ous good in the sense of the German Dangerous Goods Reg-
ulation.
●Keep the neutralisation granulate away from children.
●Only the genuine GENO-Neutralit Hz of the manufacturer may
be used for the neutralisation systems.
●Neutralisation granulate is alkaline and can cause chemical
burns and irritation when coming into contact with the skin or
the eyes. Avoid any skin/eye contact with the neutralisation
granulate.
●Use personal protective equipment when working on the
product.
●Neutralisation granulate may damage surfaces when covering
them.

3 Product description
3.1 Intended use
●The neutralisation system GENO-Neutra N is suitable for the
neutralisation (increase of the pH-value to > 6.5) of gas con-
densate originating from gas-fired heat generators (condens-
ing boilers) and/or exhaust systems made of stainless steel,
plastic, glass, graphite and ceramics according to work sheets
DWA-A 251:2011 and DVGW VP 114 up to the specified ca-
pacity.
3.1.1 Possible applications
●The neutralisation system GENO-Neutra N can be used for
the neutralisation of condensate containing iron, manganese,
aluminium and zinc particles. It is possible that the neutralisa-
tion granulate might clog and considerably impair the function
of the neutralisation system. Suitability must be checked by
own tests, if necessary, and regular cleaning of the neutralisa-
tion system with replacement of the granulate must be pro-
vided for.
●In case of condensate containing an extremely high amount
of dirt, we recommend installing an activated carbon filter up-
stream. This increases the service life of the filter material of
the neutralisation system.
The neutralisation system can be equipped with an optional over-
flow warning switch (refer to chapter 3.4).
In the event of a malfunction, this alarm device must visibly indicate
the alarm and, if necessary by switching off the heat generator, pre-
vent the system from overflowing and causing consequential damage.

3.3 Functional description
The condensate flows unpressurised into the settling area of the
neutralisation system. The condensate is then distributed via the in-
tegrated dividers and flows through the neutralisation granulate.
Condensate by-products such as combustion residue or unburnt hy-
drocarbons are retained.
The neutralisation granulate is dissolved and the condensate neu-
tralised. Afterwards, the condensate flows to the drain.
The amount of neutralisation granulate included in the scope of sup-
ply corresponds to the initial filling required for 12 months at maxi-
mum capacity.
The pH value of the discharged condensate can be checked by
means of pH indicator strips.
Neutralisation granulate should be refilled before the pH value falls
below 6.5.
The neutralisation system can be equipped with an optional overflow
warning switch (refer to chapter 3.4). When the maximum filling level
is reached, a fault signal is triggered.

In case to GENO-Neutra N-210, you can adapt the filling area for
the neutralisation granulate according to the capacity of the con-
densing boiler to be connected.
This is done by repositioning the plug-in plates.
In addition, the hose connection for the inlet can be converted from
DN 25 to DN 20 with the connection nozzle included in the scope of
supply
