Assembly and Installation
6. Install the suction line.
To do this, shorten the free end of
the suction line so that the foot
valve hangs just above the base of
the storage tank.
With feed chemicals with impurities
or sediment, shorten the free end of
the suction line so that the foot
valve hangs at least 50 mm above
the base of the storage tank.
Keep the suction line and the suc‐
tion height as short as possible.
Route the suction line with an
upwards slope.
7. Install a foot valve.
