• If the drain line is also being used by other
equipment/plants, it must be correspondingly
dimensioned
• Within the downstream system, the indivi-
dual connections are not secured from each
other against backflow. If required, provide
individual protection.
• The waste water connection has to be
determined according to DIN EN 12056 or
DIN 1986-100. In general, the vent hole
in the medium pressure chamber (normal
functional case pressure fluctuation) only
allows a few drops of water through. During
malfunctions (failure of the protective
cartridge BA), the vent hole could allow
the entire volume flow from the connection
line through. For that reason, make sure the
wastewater connection according to DIN EN
12056 and DIN 1986-100 is sufficiently large.
Base the dimension on the volume flow that
could arise through the line connection on
the backflow preventer.
• Perform a leak test after installation and before
commissioning.
