1.3 Safety instructions
1.3.1 Electrical danger
ELECTRO_NO_HEADER
Risk of electric shock
No electrical wiring or equipment that is
not splash-proof may run or be stored
below the device. Electrical devices/
equipment located in the vicinity of the
device must be splash-proof or comply
with the legal regulations for wet rooms.
Only the supplied power supply unit may
be used to connect the unit to the power
supply. This reduces the mains voltage
for operating the electronics to a harm-
less low voltage of 9 V.
A splash-proof socket is required for
connection to the electrical grid, in
accordance with the legal regulations for
wet rooms.
Only low voltages can be used for the
remote transmission of the fault indica-
tion via the potential-free output!
Switching voltage: maximum 24 V
Amperage: maximum 1 A
1.3.2 Warning of property damage
WARNING
Risk of water damage or damage
to property
The device may only be installed by
qualified technical personnel.
The installation room must be dry and
free from frost.
The ambient temperature must not
exceed 30 °C! In higher temperatures
or direct sunlight, material damage may
occur up to and including breakage of
device parts.
An adequately sized wastewater connec-
tion (e.g. floor drain) in compliance with
DIN 1986 must be provided.
In order to ensure safe drinking water
hygiene, a free discharge of the waste-
water acc. to DIN EN 1717 must be
ensured.
The pipe must be able to safely support
the device (weight: see chapter 8). If nec-
essary, the pipes must be provided with
additional fastenings or support.
If no bypass valve is installed, a shut-
off valve must be installed upstream and
downstream of the unit in order to inter-
rupt the water supply during installation,
maintenance, repair or malfunction of
the device.
Install the device in a vertical position
(± 5°); the connection for waste water
from backwashing must be directed
downwards. Otherwise, water may
escape and cause water damage.
For the installation of the device in
domestic water piping, only use the sup-
plied built-in rotary flange (see chapter
3.2).
The flange surface of the rotary flange
fitting must be upright!
The rotary flange fitting must be fitted so
that it is free from mechanical stress or
strain. Otherwise mechanical damage to
the pipe or the rotary flange fitting up to
and including breaks can result.
For proper sealing the profile of the pro-
file flange seal must point towards the
rotary flange fitting (see Figure 3).
Prior to plugging in the device, ensure
that the wastewater connection is func-
tional.
Only operate the device in a technically
faultless condition:
