NOTE:
Make sure that the FLOW marker is parallel to the pipe and points to the correct
flow direction. On a horizontal pipe the nozzle points downwards and on a vertical pipe
it points to right. The SD sensor system must always be installed in horizontal position
and on the side of the pipe.
3.
Drill two holes – 50 mm (2”) and 25 mm (1”) – as guided by the
sticker.
4. Remove the bridge between the holes so that the opening is exactly the shape of
the sticker.
