2 | Appropriate application
The Euro system separator, construction design BA, is a safety device to be in-
stalled in water pipes if special withdrawal points or appliances are connected to the
drinking water supply. The Euro system separator prevents the back-flow, back-
pressure and back-suction of modified drinking water into the drinking water net-
work. The construction design BA is approved as
safety device for systems up to
and including liquid category 4 as per DIN EN 1717, part 5.2 (refer to chapter B;
classification of liquid categories).
Attention! System separators are safety devices. They protect the drinking water
from modified drinking water. They can only work reliably provided inspections and
maintenance are carried out at regular intervals.

Fig. C-1: Detailed drawing of
Euro system separator GENO-DK 2-Mini
The system separator consists of a housing (item 1), a hous-
ing lid with connection threads for test sockets (item 2), a
non-return valve on the inlet side (item 3), a non-return valve
on the outlet side (item 4) as well as a discharge valve
(item 5).
The two non-return valves separate three different zones of
three different pressures:
Primary pressure zone (item A): Area upstream of the non-re-
turn valve on the inlet side
Middle pressure zone (item B): Area between the non-return
valves
After-pressure zone (item C): Area downstream of the non-
return valve on the outlet side

Note: Prior to start- up, the air above the membrane must be released in order to
ensure safe operation (item 7).
Attention! If the bulge of the cap sieve (item 6) protrudes into the system separator,
the non-return valve (item 3) on the inlet side might be actuated, releasing perma-
nent draining. Therefore, it is compulsory that the cap sieve is installed with the
bulge directing opposite the flow direction.
