Assembly

It is necessary during installation to comply with local
requirements, to follow codes of good practice and to follow
the installation instructions.
The installation location should be protected against frost and
be easily accessible
4.1 Installation Guidelines
• Install shut-off valves
• Install in horizontal pipework with spring bonnet
directed upwards
• Ensure good access
Cold drinking water
DN65 - DN200
10 bar
DN65 - DN100:
0.5, 1 or 1.5 bar as required
DN125 - DN200:
0.5, 1 bar as required
Opening pressure + 1 bar
40 °C
Horizontal with spring bonnet
upwards
GB
– Pressure gauge can be read off easily
– Simplifies maintenance and inspection
• Mechanical disconnectors must not be fitted in any
areas or ducts where poisonous gases or vapours
may be present or where flooding can occur
• In order to avoid flooding, it is recommended to
arrange a permanent, professionally dimensioned
wastewater connection
• These armatures need to be maintained regularly
4.2 Assembly instructions
• Flush connecting pipework thoroughly before
installation
• Install the backflow preventer with good accessibility
and with flow in the correct direction
• Install the backflow preventer only in horizontal
pipework and with the discharge tundish 
downwards
• A clearance of A
backflow preventer for maintenance purposes
DN 65 80
Amin 170 200
• It is recommended that a Y-strainer  (e.g. FY 69) be
fitted upstream to protect the backflow preventer
against coarse dirt
• Fit shut-off valves  and  either side of the
backflow preventer
• Install a small drain cock  upstream of the backflow
preventer
• Connect discharge pipe to discharge tundish 
4.3 Commissioning
As supplied the hydraulically actuated changeover valve is
closed and the backflow preventer is in the shutoff position.
Commissioning should be in the following sequence:
1. Slowly open shut-off valve 
When reaching the minimum inlet pressure the
backflow preventer turns to flow position so that the
complete pipe unit is filled up to the shut-off valve 
2. Slowly open shut-off valve  . Fill and vent the
system
3. When the system has been filled, the backflow
preventer is ready for use (the backflow preventer is
then in the flow position).
Backflow preventers of this type are normally in the flow
position. Shut-off occurs only when the supply pressure falls
below the operating pressure of the pipe separator.
The operating position is indicated on the spring bonnet  .
• Shut-off position: Green spring bonnet  is visible.
The backflow preventer has shut-off
• Flow position: Green spring bonnet  is not visible
