NOTICE
Overpressure at the suction port connection
The unit will be destroyed

The pressure on the suction port connection IN may not exceed -0.4 bar to
0.6 bar.

Proceed as follows for the hydraulic connection:
1.
Connect the outlet port (OUT) of the filtration unit with the corresponding
hydraulic reservoir.
2.
Connect the inlet port (IN) of the filtration unit with the hydraulic system.
If the filtration unit is not fitted with a motor-pump unit, then connect the inlet
port (IN) with the return-flow line of the hydraulic unit.
If coarse contamination (>100 µm) such as weld spatter or similar
material is to be expected, then an additional suction strainer must be
installed upstream of the filtration unit in order to protect the pump.
If the filtration unit is mounted below the oil level, shut-off valves at
the inlet (IN) and outlet ports (OUT) must be installed.
