2. Description of function
BA type backflow preventers are divided into three pressure
zones. The pressure in zone
which in turn is higher than in zone
connected to zone which opens at the latest when the
differential pressure between zones
bar. The water from zone
check valves close and therefore separate zone
and . In this way the danger of back pressure or back
syphonage into the supply network is prevented. The pipe-
work connection is interrupted and the drinking water network
is protected.

7. Assembly
7.1. Installations Guidelines
• Install shutoff valves before and after backflow preventer
• Install in horizontal pipework with the discharge valve
downwards
• Ensure good access
- Simplifies maintenance and inspection
• If a fine filter is not installed in the drinking water system,
the installation of a filter with a mesh width of 100µ m is
recommended in front of the backflow preventer.
• In the case of fluctuating pre-pressure or an input pressure
over 10 bar, we recommend the insertion of a pressure
,
regulator in front of the backflow preventer.
• Do not install in places where flooding can occur
• The installation environment should be protected against
frost and ventilated well
• Install discharge pipework which has adequate capacity
• Thoroughly flush pipework
7.2. Assembly instructions
1. Thoroughly flush pipework
2. Install backflow preventer
• Mount dirt strainer on the input side
• Install in horizontal pipework with discharge connection
directed downwards
• Note flow direction (indicated by arrow)
• Install without tension or bending stresses
• Provide a straight section of pipework of at least five
times the nominal valve size after the backflow
preventer
3. Attach drain pipe to discharge connection (plastic pipe
HT 40)
4. The appliance is ready for use
