Conversions, changes
WARNING
Unauthorised conversions and
changes are forbidden for safety
reasons. These can impair the
functioning of the device, lead-
ing to leaks and, in the worse case
scenario, to bursting of the device.
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
harmless low voltage of 24 V.
4.10 Maintenance, repair,
spare parts
CAUTION
The device may only be installed
by qualified technical personnel.
Only use original spare parts for
repairs.
Before performing work on the
device that goes beyond pure
operational use, the device
must be depressurised! If this is
ignored, the result may be uncon-
trolled escape of water result-
ing in water damage to the build-
ing/home.
After unscrewing the device from the built-
in rotary flange for maintenance or repair,
leakage might occur if not properly re-
attached. For reattachment, observe the
instructions for mounting the device (see
3.3).
4.11 Temporary removal of the
device
WARNING
If the device is removed due to an
interruption of operation:
•
Protect the flange surfaces
against damage to ensure proper
sealing.
•
Protect the device from dirt so
as not to impair drinking water
hygiene.
•
Store the device in a frost-free
place to prevent damage caused
by freezing water and leakage.
When recommissioning the device, proceed
as with a new installation.
