10.1.2 Fitting the safety valve
Note
The safety valve supplied must not be used in Belgium.
For use here please use standard safety valves (see also
pricelist).
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 f Install a type-tested safety valve in the cold water supply
line. Please note that, depending on the static pressure, you
may also need a pressure reducing valve.
f f Size the drain so that water can drain off unimpeded when
the safety valve is fully opened.
f f Fit the discharge pipe of the safety valve with a constant
downward slope and in a room free from the risk of frost.
f f The safety valve discharge aperture must remain open to the
atmosphere.

f f When routing the new power cable, ensure that it is water-
proof as it passes through the existing cable grommet, and is
correctly routed and connected inside the appliance.
