Automatic cleaning of self-cleaning filters
Make sure the drain on the self-cleaning filter is connected to the tank with a hose
before starting cleaning.
There are two methods for cleaning:
• Continual cleaning:
The filter cock is left open so that cleaning is carried out during spraying.
In order to use the filter in this way, you must check that the unit’s intake flow rate
is sufficient to supply both the drain for the self-cleaning filter in addition to the unit
itself.
This check is carried out as follows:
1
Protective gloves, goggles and clothing must be worn.
2
Open the self-cleaning drain completely by turning the knob
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".
