5 Connect the blow-off line to the safety over-pressure valve and
diaphragm expansion vessel in accordance with EN 12828.
▪ Any steam or heating water which may escape must be drained
by a suitable blow-off line with constant gradient in a frost-pro-
tected, safe and observable manner.
▪ Install the line in such a way that the protective cover of the
Daikin Altherma EHS(X/H) is simple to put on after assembly.
▪ Check the seat of the drain hose on the safety pressure relief
valve. If necessary, connect and install a separate hose.
6 Connecting a diaphragm expansion vessel.
▪ Connect a suitably dimensioned and preset diaphragm expan-
