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.

To avoid thermal damage to the isolation valve sealing, you must separate the valve body
from the valve assembly before it is welded onto the pipe.
