Continuous wash filters
Before doing anything, make sure the filter’s discharge outlet is connected to the
tank with a hose.
The unit can be washed in the following two ways:
• Continuous wash (recirculating):
The filter cock is left open so that cleaning is carried out during spraying.
To use the filter in this mode, check that the unit’s input flowrate is sufficient to feed
both the unit and the filter outlet itself.
This check is carried out as follows:
1
Protective gloves, goggles and clothing must be worn.
2
Completely open the filter outlet by turning the tap anticlockwise.
3
Follow the steps for the adjustment of operating pressure (plea-
se see par. 5.1 - Calibration of operating pressure).
4
After the calibration of the operating pressure, the drain cock
can be left open so that the filter is cleaned automatically during
the use of the unit.
Should it prove impossible to reach operating pressure, the
filter cannot be used in this way and must be cleaned by
"regular cleaning".
