IV. The operating language has been changed
and the AQA total unit should now be back
in Standby mode.
8.2.2. Changing the polarity times
Changing the polarity time can affect the
performance of the AQA total unit and should
therefore only be implemented by specially trai-
ned tech-nicians or our factory customer servi-
ces.
9. Troubleshooting
The AQA total unit is user-friendly and problem-
free during normal operation. However, error
messages may occur in exceptional cases under
unexpected working conditions. Error messages
are reliably indicated by a red lamp on the control
box. Open the control box and check what type of
error is displayed on the LCD.
Reasons for error messages:
A cause of error messages are burst signals.
These are voltage peaks in the power network
that are produced when inductive mains loads
are disconnected from the mains. This problem
can be resolved by using commercial, high quality
mains filters.
The hydraulic conditions can be affected by poor
water quality (high contamination load, water does
not comply with Drinking Water Ordinance). Ensure
that a drinking water filter is installed upstream of
the system and that the water complies with the
national regulations for drinking water.

faulty fuse. To find out
which slave circuit board
the error is on:
Check which slave circuit
board (number above the
board) the yellow LED
lamp is flashing on (8 x per
second). Check the fuse on
this board. Then check all
red LED lamps

connectors on this board
and the connection of the
electrode plug on the
corresponding cartridge.
If the connections are ok,
this working unit must be
replaced due to the poor
water quality. Normally, how-
ever, all refills
Fuses
should be replaced at the
same time (see refill repla-
cement).
9.1.2. Turbine error
A turbine error may result from contaminated
load, which can be caused by poor water quality
or the lack of an upstream pre-filter.
The turbine measures the volume of flowing

water and is located in the connection piece on
which the working unit is attached.
Check first of all that the cable screwed into the
connection piece is correctly fitted (Hall sensor)
or whether the Hall sensor itself is contaminated.

Hall-Sensor
When screwing in the sensor, correct fit is essen-
tial as otherwise the sensor could be damaged.
If the error is not resolved by these measures, the
turbine must be serviced (usually due to conta-
mination). Please contact our works customer
services.

10. Warranty
In the case of a fault during the warranty period,
please contact your contract partner, the installa-
tion company with details about the unit type and
production number (see technical data or rating
plate on unit). The current national legal warranty
conditions apply.
Operator obligations
You have purchased a durable and servicefriendly
product. Nevertheless, every technical system
requires regular servicing and maintenance to
ensure correct functionality. A pre-requisite for
functionality and the warranty is to comply with
the specifications set out in these operating in-
structions. .
This concerns, in particular:
- The intended use of the AQA total units
- Operation within application limits
- Correct installation by an authorised specialist
firm
- Implementation of regular inspections
- Implementation of service and maintenance
works by your installation company or our
service engineers (specialist experts) during
every refill replacement.
All servicing and maintenance work, and the re-
placement of wear or spare parts, must be car-
ried out by trained personnel only (unit installation
company or our works customer ser-vices). Only
original BWT spare and wear parts may be used!
We recommend that you agree a maintenance
contract with your installer or with BWT customer
services.
