4.12.4 TOP-MIX PREMIXER VERSION (OPTIONAL)

The premixer for this version lets you adjust the pressure independently, avoiding having to change the work settings of the machine every time you have to do the premixing.

The differences with the FULL-MIX version described previously regard the pressure regulator valve (with knob M and manometer) installed on the premixer and a 3-way deviator tap installed on the machine that deviates the delivery of the pump to the premix or the pressure regulator of the Campo. To use the TOP-MIX version proceed as follows:

a)turn the lever of the delivery deviator to the TOP-MIX position as shown in the pictogram on the machine.

b)adjust the pressure of the Top-Mix to roughly 10-12 bar with knob M (the manometer lets you check the actual pressure)

c)for mixing and washing the tin, proceed as indicated in the previous paragraph relevant to the FULL-MIX

NB: At the end of all of the operations put the lever of the deviator back into the work position.

4.13 WASHING THE SPRAYER

Thoroughly wash the machine after each treatment pumping clean water through the circuit and clean the suction and delivery filters.

Warning: Dirty equipment is very dangerous for the people and environment. Discharging the residues of washing in the environment without taking precautions is forbidden as this pollutes watercourses. Distribute the residues on the treated field.

WARNING: The tank washing is controlled by tap N. 1, premix N. 2 and stirrer N. 3.

4.13.1 CIRCUIT WASHER ANDTANK WASHER

Some machine models are fitted with a circuit washer tank (FIG.11). 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) 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.

NB: at the end of the washing cycle, if there is the risk of frost, pour roughly 500 grams of normal antifreeze for auto vehicles into the tank.
