materials.
DHW line
Stainless steel, copper and plastic pipework are approved ma-
terials.
10.1.2 Fitting the safety valve
Note
If the water pressure is greater than 0.6 MPa, install a
pressure reducing valve in the "cold water inlet".
The maximum permissible pressure must not be exceeded (see
chapter "Specification / Data table").
f Install a type-tested safety valve in the cold water supply
f
line. Please note that, depending on the static pressure, you
may also need a pressure reducing valve.
f Size the drain so that water can drain off unimpeded when
f
the safety valve is fully opened.
f Fit the discharge pipe of the safety valve with a constant
f
downward slope and in a room free from the risk of frost.
