Safety
1.3.1 Electrical danger
ELECTRO_NO_HEADER
Risk of electric shock
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 24 V.
A splash-proof socket above the device,
at a distance of no more than 1.5 m, is
required for connection to the mains, in
accordance with the legal regulations for
wet rooms.
The power supply unit must be discon-
nected to make the electrical installation.
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.
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 device in order to
interrupt the water supply during instal-
lation, maintenance, repair or malfunc-
tion of the device.
For the installation of the device in
domestic water piping, only use the sup-
plied built-in rotary flange (see chap-
ter(siehe Kapitel 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 (siehe Figure 4).
Only operate the device in a technically
faultless condition:
•
Check for damage prior to installa-
tion.
•
Immediately have any malfunctions
in operation rectified by qualified
technical personnel.
The appliance must not be exposed to
strong vibrations.
The mains voltage must not be inter-
rupted (e.g. via a light switch). If the
device is not permanently supplied with
power,
•
a possible leakage cannot be
detected.
•
the leakage protection cannot close
in the event of a leakage.
Persons who, due to their physical, sen-
sory or mental abilities or their inexperi-
ence or lack of knowledge, are unable to
operate the device safely may not oper-
ate it without supervision or instruction
from a responsible person.
After the leakage protection has closed
due to a limit being exceeded, first check
whether there is a leak before opening
the leakage protection again.
If there is a device for hot water prepa-
ration (in particular a gas or electrically
operated instantaneous water heater
or a heating boiler), the manufacturer's
instructions for the water heater must
