4 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
– This position ensures optimum filter efficiency
• Ensure good access
– Pressure gauge can be read off easily
– Simplifies maintenance and inspection
• Install a strainer upstream of the mechanical
disconnector
– To protect the mechanical disconnector from dirt
• No further unprotected mains water supply may be
connected downstream of the mechanical
disconnector
• 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
min
must be provided above the
backflow preventer for maintenance purposes
• Connect electrically actuated changeover valve with
suitable transmitter (pressure control device, sensor,
water level indicator, etc.) in the system
• 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 
• If pressure shock is anticipated in the outlet side of the
backflow preventer, a pressure shock damper or
expansion vessel must be fitted on the system down-
stream of the backflow preventer
