the safety assembly (accessory or on-site provi-
sion) in the cold water line to DIN 1988 and EN 806
(see page 11).
Recommendation:
Install the safety valve above the DHW cylinder to
protect it against contamination, scaling and high
temperatures.
c
: According to W3 "Principles for creating pota-
ble water installations", safety valves must be
drained directly via a visible unrestricted drain or via
a short outlet line to the drain network.
Note
Do
not
connect the DHW cylinder safety valve to
hose
L
.
Never
change the position of hose
