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.
5. Installation
5.1. General conditions
The system must be installed, in compliance with
these installation and operating instructions by a
water supply company or by an installation compa
-
ny 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 sys
-
tem.
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.
5.2. Test section/rinsing valve
The installation of a test section is a requirement for
the warranty – particularly when retrofitting the AQA
total unit into an existing installation.
The test section is an easily removable, new pipe
section, which should have a pipe length/pipe dia
-
meter of approximately 6:1.
It must be fitted downstream of the AQA total
system.
In addition to the test section, a water sampling
point must be installed downstream of the AQA to
-
tal unit. This outlet valve is used as the rinsing valve
and drinking water sampling point and it must have
a minimum nominal diameter of DN 15.
5.3. Shut-off valves/bypass circuit
A shut-off valve must be installed upstream and
downstream of the unit. If a bypass circuit is requi
-
red by national installa-tion regulations, it must be
installed as per these requirements.
As the branch of each working unit in the AQA to
-
tal supply distributor can be individually closed by
the supplied shut-off valves, the water supply can
be ensured during Refill replacement even without
a bypass circuit.
5.4. Installation/assembly
5.4.1. Remove unit from packaging and check
for completeness.
5.4.2. Attach mounting hooks to wall as per
diagram (used to mount the AQA total
unit) using the supplied dowels and
screws, then check for tightness.
