1. Installation
(See installation sketch number: 88-700-202)
1.1 Remove black covers (transportation lock) from the
supply and discharge openings!
1.2 Shake the neutralisation unit in order to distribute the
granulate evenly.
1.3 Floor or wall installation is possible.
In case of floor operation with direct infeed into a condensate
pump, attach the mounting feet (number 18) underneath the
fixtures (number 8).
For wall installation, first attach the fixture
vertically using dowels and screws (number 21). Then secure
the neutralisation unit with the bracket (number 9).
1.4 Attach the booster pump (number 12) to the mounting
strip (number 10) on the filter housing.
Connect the air hose (number 13) to the booster.
Attach the cables to the booster pump (12) according to the
connecting diagram (see page 10). Booster operation
synchronised with the burner.
Electrical work must be completed by a trained professional!
Caution! Life – threatening risk of electric shock!
In order to prevent the condensate flowing back into the
booster, always securely attach it over the neutralisation.

1.5 Connect the inlet nozzle (number 1) to the condensate
drain on the boiler.
In order to ensure proper functionality, a build-up of
condensate in the neutralisation unit must be avoided.
1.6 The supply hose should form a slight dip which will
prevent the generation of noise. (See illustration)
Drain nozzle pointing down!
Connect the drain to the sewer.
If self-drainage is not possible, use a condensate pump. (See
to the wall
connecting diagram.)
1.5 Check for leak-tightness!
2. Operation
Condensate flows through the neutralisation granulate and is
neutralised.
3. Functional verification
1. Check the fill level! If the granulate level is below the
maximum (red sticker, number15), maintenance is required.
2. Measure the pH value using the pH indicator rods! If the pH
value is below 6.5, maintenance is required.
3. Neutralization can only take place if the liquid runs through
the granulate!
The granulate fill level must be above the condensate level!
In order to eliminate the risk of plugging, the inlet and
drain nozzles must not be fully covered with granulate.
4. Maintenance
Attach the "Maintenance" sticker to the boiler so it is
easily visible!
Complete the maintenance records in the operating
manual (last page)!
Verify neutralisation at least once a year!
Since the amount of condensate may vary, verification at
shorter intervals is recommended immediately after the
heating equipment is commissioned.
1. Loosen the connecting screws and remove the filter
housing from the fixture.
2. If the granulate is caking, loosen it using the enclosed
cleaning rod.
3. Fill with fresh granulate with standing neutraliser up to the
"filling level" (number 22) label.
Deviations of approx. +/- 5cm are normal with different bulk
densities!
Leave at least 3 cm of head space above the granulate
horizontally.
4. Install the filter housing. Check for leak-tightness.
5. Reactivity and disposal
The granulate disposes of itself. Carbonic acid in the
condensate combines with the granulate, forming magnesium
hydrogen carbonate Mg(HCO 3 ) 2, while the NOx combines
into magnesium nitrate Mg(NO 3 ) 2. Both are fully soluble salts
that are very common in nature. The granulate is approved for
drinking water treatment.
Granulate residue is disposed of in ordinary household
garbage.
