Conversions, changes
WARNING
Unauthorised conversions and

reasons. These can impair the
functioning of the device, leading
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.

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 egress of water result-
ing in water damage to the build-
ing/home.
