3. Application area

3.1. Purpose of the system

BWT water.
Your daily drinking enjoyment – a must have pleasu-
re for the entire family.
The revolutionary 3 phase technology in AQA total
brings you the new power of drinking water – direct-
ly into your home.
AQA total from BWT with the revolutionary 3 phase
technology:
• Daily drinking enjoyment full of vital
elements
AQA total retains all valuable minerals
in the drinking water. Conscious daily enjoy-
ment of BWT water is your healthy
provider, full of vital elements with essential
magnesium and calcium for your body.
• Best limescale protection for your
drinking water installation
The bipolar technology - awarded inter national
test marks (ÖVGW, DVGW, etc.) and winner
of the "Stiftung Warentest" evaluation – stabilizes
lime in the water through the formation of
nano-crystals.
• Phase 3: Efficient corrosion protection
for your drinking water installation
AQA total supports the natural formation of an
effective coating against surface corrosion.
AQA total – environmentally-friendly, operation-free
and maintenance-free limescale protection system
for the reduction of limescale precipitation in drin-
king water pipes (712 ppm/40° German hardness)
and the downstream, closed hot water heaters
(176°F/80°C).
The new technology in AQA total:
Drinking enjoyment with vital elements
Effective limescale protection
The working unit consists of a base unit and a refill
with a three-dimensional electrode composed of
conducting and non-conducting particles. When a
defined current/voltage pulse is applied, the lime-
carbonic acid equilibrium is locally shifted. Pulse
height and width are dependent on the actual water
properties and flow rates.
They are automatically controlled by the electronic
control system. Following the local shift in the lime-
carbonic acid equilibrium, minute calcium crystals,
so-called nano-crystals, are formed in the unit.

The small size of these nano-crystals means that they
carry an electric charge which prevents them from
growing together. The nano-crystals are therefore
capable of trapping the lime in the water and so
reduce limescale deposits within pipes and water
heaters.
The gentle treatment by AQA total retains all essenti-
al minerals in the water, above all calcium.

4. Installation preconditions

Comply with local installation regulations,
general guidelines, general hygiene conditions and
technical data.
The installation location must be protected against
frost and provide protection against chemicals,
dyes, solvents, vapours and
environmental influences. The ambient temperature
must not exceed 40°C. Protect the unit from direct
sunshine and UV light.
The water meter area up to 1 m after the AQA total
unit must be corrosion resistant; we recommend the
use of a HydroMODUL domestic water distributor,
which also enables a rapid and cost-effective instal-
lation. The unit must have an upstream DIN/DVGW
(or ÖVGW) certified drinking water filter to protect
against foreign material. A pressure reducer should
be installed upstream to protect the entire installation
and system if there is a network pressure > 4 bar.
For community water supplies, we recommend a
backwash filter (automatic or manual), and a BWT
filter with changeable cartridges for spring water.
Both can be easily docked on to a DR pressure re-
ducer module. At high inlet pressures (e.g.: 10 bar
or more) it may be necessary to install a calming
section downstream of the pressure reducer.
A test section is required for function checks. This
can be easily implemented with 2 HM extensions (=
244 mm) in the HydroMODUL system.
A mains connection (230V/50 Hz fuse contact so-
cket) must be available nearby.
Caution: With pressure fluctuations and surges, the sum
of pressure surge and pressure at rest must not exceed
the nominal pressure.
The positive pressure surge must not exceed 2 bar
and the negative pressure surge must not exceed
50% of the working pressure that is set (see DIN
1988, Part 2.2.4).
If these conditions are not complied with, the techni-
cal function can not be guarenteed.
