This can be done simply with 2 HM-extensions (=
244 mm) in the HydroMODUL system.
4. Fitting
Make sure that there is a sheltered socket in the
installation area. The length of the connection
cable of the device is 1 metre.
I. Unpacking the device
Remove the device from its packaging and check
the delivery to see that everything is there and for
any damage caused during transport.
II. Flow direction
Please note the desired flow direction prior to
assembly. The device comes as standard with a
flow direction "from left to right". If you need to
change the flow direction, then proceed as
follows:
a. Remove the device cladding after releasing
the two locking screws (knurled screws) on
the side of the device (see Fig. 1 und 2).
b. Set the device down with its back facing up
on a soft base (see Fig. 3).
c. Release the assembly bracket and remove it
(see Fig. 4).
d. To release the connector, press the circlip on
both flaps together and pull it in the
direction of the connection (see Fig. 5).
e. Turn the connection 45° anticlockwise and
remove it (see Fig. 6).
f. Turn the base in the flow direction and
re-connect it to the device (see Fig. 7, 8, 9).
g. In so doing, please note the flow direction
arrows and make sure the circlip clicks in. If
the AQA nano is to be fitted in a vertical pipe,
only turn the connector 45°. Then this is
fitted again and secured.
h. Then fit the support bracket back to its
original position.
III. Connecting to the water pipe
Connect the device using the screw connection
supplied to the pipe, and using the fastening
bracket, screws and dowels supplied, to the wall.
The projection of the tubular axle in AQA nano
may be between 80 mm and 100 mm.
The minimum ground clearance of the tubular axle
or the assembly point in vertical pipes is 500 mm.
After preparing the pipe, fit the wall bracket and
set the device on the wall bracket.

The two screws connect your AQA nano lime-
scale protection device to the wall bracket (see
Fig. 10 and 11).
5. Start-up
After the installation or after changing the lime-
scale protection unit, open the shut-off valve in
front of the AQA nano limescale protection system
and pressurize the device. Then check that all
connections are properly sealed.
Important!
AQA nano and the integrated limescale protection
unit are supplied dry for hygienic reasons. For this
reason, we recommend thoroughly rinsing the
device on start-up by opening a drain valve for
approx. three minutes. This also allows any
shavings and other impurities introduced on
installation to be rinsed out.
Then put the mains cable into the protective
contact socket provided and check that the two
green indicator LEDs are working in the inspection
window. Both indicator lamps must light up. When
water is removed, the upper indicator LED starts
to flash every two seconds. If this signal is not
displayed, then check the flow direction, the
power supply and the cable connections.
The device is now ready for use!
6. Operation
AQA nano displays all operating conditions
through the two indicator LEDs in the inspection
window (see Fig. 12).
When water is removed, the upper indicator lamp
flashes every two seconds. If the indicator LED
"IN OPERATION" goes out, then the limescale
protection unit, as described in Item 7, must be
changed. If the indicator lamp "POWER" goes
out, there is either a fault in the power supply or
the device has been seriously damaged. If the
indicator lamp "POWER" does not flash when
water is removed, then the water is not removed
by the device or there is a fault in the device.
In this case, please contact your fitter or your
BWT technical advisor.

7. Changing the limescale protection
unit
As soon as the indicator LED "IN OPERATION" goes
out, the limescale protection unit must be changed.
I. Isolate the water pipe before and after
AQA nano and release the locking screws at
the side of the device (see Fig. 13).
II. Remove the device cladding.
III. By opening the black drain screw at the
bottom of the transparent cylinder, you can
carry out the pressure discharge (see Fig. 14).
IV. Unscrew the transparent cylinder then
manually (see Fig. 15).
V. Now detach the limescale protection unit (see
Fig. 16). You can, without any hesitation, put
the limescale protection unit in the domestic
waste or send it to be recycled.
VI. Open the protective covering of the new
limescale protection unit and remove it from
the packaging using the hygiene gloves
supplied (see Fig. 17).
VII. Now set the limescale protection unit on the
two titanium electrodes in such a way that the
points of the electrodes stick into the two
conduits of the limescale protection unit (see
Fig. 18).
VIII. Now push the limescale protection unit until it
clicks over the electrodes (see Fig. 19).
IX. Now tighten the transparent cylinder again
manually.
X. Now confirm that the limescale protection unit
has been changed, by holding the "RESET"
key for around three seconds (see Fig. 20).
The green indicator light "IN OPERATION"
now lights up again.
XI. Finally check that all cable connections are tight
and fit the device cladding using the two locking
screws.
8. Inspection
To guarantee the best level of hygiene safety,
efficient working and long life for the device, we
would recommend you carry out a regular visual
check of the device (at least once a week) and
check the operating status (LED lights).
Professional maintenance / servicing by your
expert fitter or our BWT customer service also
provide the highest safety levels.
9. Operator duties
Although you have purchased a durable and easy
to maintain product, every technical system
requires regular service to guarantee its correct
operation. A precondition for the operation and
any warranty and guarantee claims is the
compliance with the specifications listed in these
operating instructions. These specifications
concern in particular:
– normal use of AQA nano
– the operation within the operation limits
(s. technical data)
– correct fitting by the approved specialist
company
– Regular tests being carried out
– Service- and maintenance work being carried
out by your specialist fitter or the BWT
customer service
Protect your rights and have all the service and
maintenance work, and the replacement of spare
and wear parts carried out solely by specialist
personnel (installation company familiar with the
device or BWT customer service). Make sure you
use original BWT spare and wear parts - these will
guarantee you reliability for many years! We would
recommend entering into a service agreement
with your fitter or the BWT customer service
10. Warranty
In the case of a breakdown during the warranty
period, please contact your trade partner giving
the device type (see technical data or name plate
on the device), the installation company or BWT's
customer service. The national statutory warranty
provisions shall apply as amended.
