4.11 FILLING THE TANK

The machines for defensive crop treatments, in consideration of the safety of persons, animals and the protection of the environment, must only be filled indirectly from open water courses and only by free-falling water from the waterworks.

The pipe used for filling must never come into contact with the liquid inside the tank and therefore the water must always fall over the upper edge of the filling inlet and through the filter installed on it.

The tank is fitted with a transparent graduated band that shows the exact quantity of liquid inside. This reading is precise if the tank is on flat ground; the actual total capacity coincides with the highest number. All the filling systems fitted by Unigreen on their production machines or on request are antipollution and stop the liquid overflowing out of the tank.

a)FILLING WITH THE 3-WAY DEVIATOR (Fig. 5).

It is possible to fill the tank using the pump and the floating filter kit G (cod.1002/0080F) with 6 metres of rubber hose (the floating filter lets you always and only suck up clean water).

=connect hose T to deviator D using the union hose adaptor supplied.

=turn the lever of deviator D to the filling position.

=place the other end of the hose, on which you fitted filter G, in the watering point.

=start the power-takeoff leaving pressure regulator C in the draining position (you don’t have to put the pump under pressure).

=the filling speed in litres/minute is equal to the delivery of pump P.

=visually check the level of the liquid in the tank and after filling stop the pump and put the lever of deviator D back in the working position.

=disconnect pipe T from deviator D.

b)FILLING WITH THE SUCTION FILTER (Fig. 3-5).

If the 3-way deviator isn’t fitted you can fill the tank using the coupling on the cover of the suction filter. Unscrew the rear wing nut of the filter and using a G1"1/2 threaded union, connect pipe T with the floating filter to the coupling. Also in this case the filling speed in litres/minute is equal to the delivery of the pump.

c)FILLING WITH THE ANTIPOLLUTION EJECTOR (Fig. 6)

If you are filling with an antipollution hydroejector (mounted as standard on some models) then you should proceed as follows:

=put roughly 20-30 L of water in the tank and start the pump.

=remove the cap of ejector E and insert filling pipe T.

=place the other end of the hose, on which you fitted filter G, in the watering point.

=open the tap that supplies the ejector (on pump P or pressure regulator C).

=increase the pressure until it reaches a value which is sufficient to suck up the liquid.

=visually check the level of the liquid inside the tank and after filling disconnect pipe T from the ejector, close the tap and replace the cap.

4.12 MIXING

The active principle can be mixed using the relevant stirrers before and during the treatment. Correct mixing and stirring is the basis of the correct distribution on the crops. We recommend some useful accessories such as the premixer for powders and liquids (see the following paragraph).

To mix the product in the tank proceed as follows:

a)high-pressure machines from 30 to 60 bar (FIG. N° 7): run the stirrer (or ejector) for roughly 10-15 minutes at the maximum pressure available

b)low pressure machines, max 20 bar

=with a drilled pipe on the drain, run the pump at roughly 540 RPM with the pressure regulator on drain for at least 10-15 minutes. (FIG. N° 8)
