Installation
The backflow preventer BA must be installed
horizontally. Provide cut-off valves in front of
and behind the backflow preventer. To carry out
maintenance a drain valve with a hose connection
should be installed on the shut-off valve on the
supply side.
Note! In addition, a dirt trap must be
connected upstream which prevents
the backflow preventer from damage
and functional impairments due to
coarse dirt.
Install the backflow preventer free of tension and
without flexural moment as follows:
1.
Thoroughly rinse connecting pipe
