Precautions for installation, maintenance and operation
Installation and operation
Read the manual and follow the instructions before
installation!
Installation and maintenance must be carried out by
qualified plumbers.
Provide manual to the plant operator and keep on
hand for further reference!
Make sure that the installation location is frost-pro-
of and not prone to flooding.
Do not use any fast-closing valves.
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 befo-
re commissioning.
Priority must be given to the national standards and
provisions on sanitary installations and accident
prevention.

- Disregard of installation instructions.
