The inlet filter allow to fill
the tank from external
sources (wells, streams,
etc..).Filters assembled on
equipment have 50 mesh
cartridges of 0.3
– 0.4 mm
(pos. 3).
The filter must be frequently
checked while with a good
cleaning of these you get a
smooth operation of the
machine.(§:7.7)
If the liquid used in the treatment has
many impurities, it is good practice to

clean the filter with the pump on and to
wear appropriate safety clothing. Before removing the filter cap (POS.

switch off the pump and disconnect the tube from the suction filter
“3 WAY GATE VALVE
The 3-way gate valve permits to direct, inside the loop, the liquid in various directions
- During spraying in the field the level
should be placed in position 1.
- During the filling phase from wells or from
the external tanks, it can take any position.
- During the tank and circuit washing (at
the end of each treatment, chemical liquid
change or when it has required for the
periodic maintenance ), the lever must be
