Installation positions
Fine screen
The medium flow direction must correspond to
an arrow on the strainer body.
Strainers are to be installed in horizontal position
with mesh bonet directed downwards. Vertical
position is also allowed (be aware - when
medium flows upwards strainer retains all
foreign particles but is not able to collect them).
Sufficient space to pull out the mesh for
replacement and cleaning must be ensured.
