– Permissible operating
overpressure 6 bar.
– Install only type-tested safety
valves or safety groups.
Specific national regulations
are to be respected.
– Arrange the dimensions of the
drain to suit the fully-opened
safety valve. The drain aperture of
the safety valve must remain open
to the atmosphere.
– Adjust through-flow volume
max. 18 l/min at the through-flow
isolating valve (Fig.
– During the heating-up process,
water will visibly drip from the
safety valve.
