Applications
Installation positions |
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. |
