elements, including the screwed on control
unit of the AQA total 4500 unit to the
water pipe using the pre-mounted screw
connections (DN 40, 1 ½" external thread).
Important: When delivered the unit is configured
with a flow direction from „left to right". If the ne-
cessary flow direction at the installation site must
be „right to left", then the screwed components
(X +Y) must be turned around as follows with an
open-end wrench (SW/wrench size 13) and the
hexagon socket screw wrench provided.

Remove the screws (Z)
8 unit hex-head screws (M8) and
2 Allen screws
Exchange the screwed components (X + Y)
Check that the seal is fitted correctly.

Important: The screwed component MUST be
mounted with a backflow preventer (X) in the flow
direction.
3. Mount the AQA total 4500 unit on the wall
with the brackets, screws and dowels
provided. (See 6.3.c Installation diagram:
AQA total 4500) Tighten fastening screws.
4. Remove the red transport caps from the
working units.
Push the retaining ring on the connection compo-
nent upwards and turn it to the left until the stop
is reached. Push the working unit claws upwards in
the connection component and turn them to the
right by 45° up to the stop. Pull the blue retaining
ring back down. The working unit is then protected
against unintentional rotation.
5. Connect the electrode cable to the underside
of the working unit.

6. Check the system for correct installation of
power and water (as per DIN 1988, Part 4).
7. Start up the unit (see commissioning) and
check for leaks.
8. Mount the unit cladding and fasten in place
with knurled screws.

5. Commissioning

Commissioning must be implemented by trained
experts. Caution: The specified sequence must
be complied with (I-X)!
I. Close the shut-off valves upstream and
downstream of the unit and close all
installation outlets (e.g. fittings)..
II. Check correct mounting of working unit.
III. Check correct mounting of electrode plug.
IV. Open the water supply inlet. Pressurise the
unit by slowly opening the shut-off valve
upstream of the unit. When using a
multiblock, set up the multiblock so that the
entire water supply flows through the
AQA total unit.
V. Check unit for leaks.
VI. Open the shut-off valve downstream of unit.
VII. Rinsing: By slowly opening the rinsing
valve or another water tapping point
immediately downstream of the unit,
any debris caused by transport can be
flushed away. The rinsing valve must
remain open (for at least 3 minutes)
until the water runs clear. Close the
rinsing valve or other water taping
point.
VIII. Plug the mains cable into the protective
contact socket (230V/50Hz) provided. At
start-up of AQA total Energy the starting
picture and the version number are shown
on the display.
IX. After a short time an info-display appears.
Explanation of the information on the
display: 13
• actual flow rate by displayed triangle
• Time hh:mm:ss
• Water consumption since last refill-
change in m3
• Remaining capacity of the installed refill
in percent
• Calculated (forecasted) remaining
months until next refill-exchange.
X. The unit is now ready for operation.

6. Operation

The unit operates automatically and switches its-
elf on when water is used. The function should be
checked regularly by checking the display. Ple-
ase note that the unit must always be supplied
with electricity. Allow a few litres of water to flow
through the domestic installation after longer
periods of stagnancy before using the water for
drinking purposes. The working unit and the refills
are wear parts, that are subject to a natural wear
down over time.

Repeat as often as necessary. Notice: DS
means daylight saving and is used to change
automatically the time between summer- and
wintertime (e.g. summertime).
When DS (daylight saving) is on, 17 the
displayed time is marked with a star.
This causes the control to change automati-
cally between summertime and wintertime,
provided the time and date setting are cor-
rect.
There are two time formats - 12 and 24 hours.

• Usual max. capacity of a new refill
• Impulse/Liter or Liter/Impuls
(all AQA total types show IMP/L)
• Impulse per Liter given from an internal
Hall-Sensor (water meter)
• The maximum flow (peak) since start-up
or since a changed refill

AQA total provides optimal hygiene in your pipes
and for your drinking water. These high require-
ments are also met by the innovative refill system.
In comparison to other systems that do not use
a replacement system and therefore are subject
to hygienic risks (sludge and bacterial formation
in the container), the refill system from AQA total
ensures optimal hygiene for your drinking water -
for pure drinking enjoyment.
