Connecting the suction port
For the suction port connection, use a flexible hose that is resistant to
negative pressure. Avoid constrictions in the connecting lines, as they
compromise suction performance and increase the risk of cavitation.
In case of coarse contamination (> 100 µm) such as weld splatter, an
appropriate suction strainer must be installed in the suction line in order to
protect the pump.
NOTICE
Overpressure at the suction port connection
The filter unit will be damaged
►
The maximum pressure on the suction port connection IN must not be
more than -0.4 to 0.6 bar.
Connecting the pressure port
Make sure that the nominal width of the pressure line corresponds to the
threaded connection of the filter housing.
Install the return line below the oil level to prevent air from entering the fluid
in the tank
If the clogging indicator pressure displayed for the a clean
filter element is > 1 bar, use a differential pressure clogging
indicator.
