Unigreen SIRIO, EXPO, DEVIL Manual Premixing, Premixer on Cover Optional, Washing the Atomiser

a)high-pressure machines from 30 to 60 bar (FIG. N° 13): 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° 14)

=with the stirrer on a delivery, run the pump supplying the stirrer (or ejector) at the maximum pressure available for at least 10-15 minutes. (FIG. N° 13)

Some models with very small tanks aren’t equipped with mixers, you should use the drain of the pressure regulator: run the pump at roughly 540 RPM with the pressure regulator in the drain position for at least 10-15 minutes. (FIG. N° 15)

4.12.1 MANUAL PREMIXING

Dilute the active principle by hand before introducing it into the tank, (you must wear suitable protective clothing such as rubber gloves, a mask or goggles, overalls, etc.).

4.12.2 PREMIXER ON COVER (OPTIONAL):

Open the cover and pour all of the chemical powder into the filter, close the cover and open the supply tap until all of the powder has dissolved.

4.13 WASHING THE ATOMISER

After every treatment, thoroughly clean the equipment, washing it with water inside and out. Dirty equipment is very dangerous for people and in particular for children.

Discharging the residues of washing in the environment without taking precautions is forbidden as this pollutes water courses. Distribute the residues on the field or the crops where they won’t cause any damage.

4.13.1 CIRCUIT WASHER ANDTANK WASHER

Some machine models are fitted with a circuit washer tank (FIG.16). This tank must be filled with clean water and used to rinse the entire circuit including the suction, delivery, pump, pressure regulator, jets and nozzles. Thanks to the practical rotary nozzle it also rinses the inside surfaces of the tank.

NB: To completely clean the tank and the pipes of any residues of the various active principles, we recommend adding 2kg of soda to the washing liquid for every 100 L of water.

At the end of the treatment, wash the circuit and the tank.

a)Stop the diaphragm pump disengaging the power-takeoff.

b)Check you have filled the circuit washer tank (C).

c)Make sure the main control of the pressure regulator is OFF and that all the boom sectors are closed.

d)Turn suction deviator A to the circuit washer position (H2O).

e)Start the diaphragm pump by engaging the power-takeoff.

f)Increase the engine speed until all of the liquid in circuit washer tank C has been sucked up.

g)Turn the diaphragm pump off and turn deviator A to the work position (TANK).

h)Turn the main control to ON, so there is pressure in the circuit.

i)Start the diaphragm pump again and use the tank washing tap on the regulator (or on pump P) that supplies jet B.

j)After a few minutes you can close the tank washing tap

k)Distribute the washing residues over a portion of the field where it won’t cause damage.

l)After you have finished washing, stop the diaphragm pump.
