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 there-
fore only be implemented by specially trained tech-
nicians or our factory customer services.

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.

9.1. Error messages

9.1.1. Rectifying system errors
Current too low
crt. 1 2 3
Low current is usually an
indication of a poor connection
contact or 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.

red LED lamps
Then check all 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, however, all refills
should be replaced at the
same time (see refill replace-
ment).
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 essential
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-mi-
nation). Please contact our works customer services.
