Connecting the hot and cold water

> Observe the following conditions in order to correctly
fit the water connections:
– All cold and hot water pipes can be made of steel,
copper or plastic. It is important to check with the
manufacturer that pipes made of plastic can be
used with temperatures of 65 °C in normal operat-
ing mode. In addition, plastic pipes must be suitable
for a significantly higher load in the short term.
– An expansion relief valve on the cold water pipe is
not required.

– To simplify fitting the water connection, the bottom
section of the unit can be folded up (see (1) in
fig. 4.10). After fitting the connection, you must
fold the bottom section of the unit back down until
it is engaged again. The folding frame must not

be removed.
– When connecting the VED to a plastic pipe system,
a Vaillant pressure monitor (order no. 300768)
must be used.
