1. Purpose of the system

BWT water.
Your daily drinking enjoyment - a must have pleasu-
re for the entire family. The revolutionary technology
in AQA total brings you the new power of drinking
water - personally in your home. AQA total from
BWT with the revolutionary technology:
Daily drinking enjoyment full of
vital elements
AQA total retains all valuable minerals
in the drinking water. The conscious
daily enjoyment of BWT Energy water
is your healthy energy provider, full of
vital elements with essential magnesium,
calcium and oxygen for your body.
Best limescale protection for your
drinking water installation
The bipolar technology - awarded
international test marks (ÖVGW, DVGW,
etc.) and winner of the Stiftung
Warentest evaluation - stabilises the
limescale in the water through the
formation of nano-crystals.
AQA total - environmentally-friendly, operation-free
and low maintenance limescale protection system
for the reduction of limescale precipitation in drin-
king water pipes (40 ° German hardness) and the
downstream, closed hot water heaters (80 °C).

2. Function

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
22
from growing together. The nano-crystals are there-
fore 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 essen-
tial minerals in the water, above all calcium.

3. Installation preconditions

Comply with local installation regulations, general
guidelines, general hygiene conditions and techni-
cal data. The installation location must be protec-
ted against frost and provide protection against
chemicals, dyes, solvents, vapours and environmen-
tal 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 installati-
on 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 sec-
tion 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 (230 V/50 Hz fuse contact
socket) 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 tech-
nical function can not be guarenteed.
Caution: If pressure surges from neighbouring pipe
systems that exceed the actual test pressure of
the unit cannot be excluded, a suitable water sur-
ge damper must be installed to protect the unit in
compliance with applicable national standards and
regulations.

4. Installation

4.1. General conditions

The system must be installed, in compliance with
these installation and operating instructions by a
water supply company or by an installation com-
pany listed by a water supply company (comply
with applicable national requirements in other
countries).
Caution: Working on the electrical system can
endanger life. The unit must be disconnected from
the mains before any work is carried out on the
system.
Always comply with the national legal requirements
for the connection of and work on the electrical
system.
Transportation and storage
Please ensure that, during transport and storage,
the unit is protected against strong shocks, impacts
and frost.
4.2. Scope of delivery: Check unit for com-
pleteness and transport damages (intact-
ness)
