3.4 Functional description
3.4.1 Physical
The raw water enters the filling cartridge desaliQ:HB2 via the
shut-off valve and flows through the filling cartridge’s mixed bed

Product description
13 | 32
BA_TD3-GH000en_015_Aufbereitungsgruppe.docx
from top to bottom. The water is demineralised by way of ion
exchange.
The demineralised water passes the conductivity measuring cell
and flows into the heating system.
A non-return valve at the outlet of the treatment group prevents
the water from flowing back from the heating system.
3.4.2 Chemical
Mixed bed resins consist to one part of a highly acid cation
exchanger resin and to the other part of a highly alkaline anion
exchanger resin. In the mixed bed cartridges, these two
components are present in a completely mixed state.
The cation exchanger resin removes all positively charged ions,
the so-called cations, from the raw water. All cations contained
in the water, such as calcium, magnesium, sodium, are
exchanged for H+ions.
In the demineralisation process, the anion exchanger resin is
used to filter off the negatively charged ions, the so-called
anions. All anions contained in the water, such as nitrate,
phosphate, sulphate, chloride and hydrogen carbonate, are
exchanged for OH-ions.
Full demineralisation removes almost all undesired components
from the inlet water. Thanks to the highly alkaline anion
exchanger resin, silicic acid and carbon dioxide are also filtered
off. The H+and OH-ions generated in the exchange process
combine to H2O. The result of full demineralisation is pure
water.

4.1 Requirements in relation to the
installation site
Observe local installation directives, general guidelines and
technical specifications. The installation site must be frost-proof
and ensure the system's protection from chemicals, dyes,
solvents and vapours.

Installation

BA_TD3-GH000en_015_Aufbereitungsgruppe.docx
A floor drain must be provided in the installation room. If no floor
drain is available, an appropriate safety device must be installed
in order to prevent water damage.
A drinking water filter, e.g. pureliQ:K (refer to chapter 4, item 1)
must be installed upstream of the product.
A system separator, e.g. filling group thermaliQ:SB13 must be
installed upstream of the product as per DIN EN 1717 (refer to
chapter 4, item 2).

►Check the scope of supply for completeness and
possible damage.
4.3 Installing the product
1. Install the shut-off valve at the inlet side of the treatment
group.
2. Install the water meter screw connection at the outlet side
of the treatment group.
3. Install the treatment group in between without any
mechanical stress. On the inlet side, use the flat gasket
and on the outlet side, use the flat gasket with cap sieve.
4. Install the filling cartridge and the plastic cylinder. The
plastic cylinder does not have an end stop. Turn it until
the required pressing is done.
» The installation of the product is completed.
