Mounting
Connect the substation to the household piping in accordance with
the labelling at the bottom and/or in accordance with the instructions
in this manual.
If the household piping system features domestic hot water
recirculation, the substation must be connected to the recirculation
system. The circulation set for recirculation connection is not standard
equipment. The set must be purchased as extra equipment.
We recommend establishing recirculation BEFORE mounting the
substation on the wall.
For instructions about recirculation connection, see page 14.
GETTING STARTED is a quick guide and some details in connection with
installation and commissioning may require additional information,
which can be found elsewhere in this instruction manual.

4. On systems that feature a safety valve, establish a drain connection
in compliance with the applicable legislation.
