5.5 Installation of expansion tank
ATTENTION!
Too high continuous temperatures
and steam shocks may lead to
damage to property!
For this reason:
– Only use a correctly dimensioned
diaphragm expansion tank which is
suitable for the application range and
the heat transfer medium.
– Mount expansion tank at a lower
level than the safety group.
– If the expansion tank has to be instal-
led at the same or a higher level than
the safety group, always install a
thermal insulation loop.
– The expansion tank must always be
installed with the connection poin-
ting upwards.
1. Mount and connect expansion tank, see docu-
mentation of expansion tank supplier.
