unigreen 194.13 WASHING THE SPRAYERThoroughly wash the machine after each treatment pumping clean waterthrough 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 takingprecautions is forbidden as this pollutes watercourses. Distribute the residueson the treated field.WARNING: The tank washing is controlled by tap N. 1, premix N. 2 and stirrerN. 3.4.13.1 CIRCUIT WASHER AND TANK WASHERCAMPO machines can be equipped with with a circuit washer tank (FIG.11).This tank must be filled with clean water and used to rinse the entire circuitincluding the suction, delivery, pump, pressure regulator, jets and nozzles.Thanks to the practical rotary nozzle it also rinses the inside surfaces of thetank.NB: To completely clean the tank and the pipes of any residues of the variousactive principles, we recommend adding 2kg of soda to the washing liquid forevery 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 allthe 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 hasbeen 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 (BLUE) onthe regulator (or on pump) that supplies jet B.j) After a few minutes you can close the tank washing tapk) Distribute the washing residues over a portion of the field where it won’tcause 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 roughly500 grams of normal antifreeze for auto vehicles into the tank.4.13.2 WASHING WITH FULL TANK (OPTIONAL)CAMPO machines can be equipped with a discharge deviator that makes itpossible to wash the pump and circuit even with a full tank.a) Stop the diaphragm pump by disengaging the power-takeoff.b) Check that you have filled the circuit washing tank (C).c) Check that the main control of the pressure regulator is OFF and that allthe boom sectors are closed.d1) Turn discharge deviator S to the WASH positiond) Turn suction deviator A to the circuit washer position (H2O).e) Start the diaphragm pump by engaging the power-takeoff.f1) Increase the engine speed until all of the liquid in circuit washer tank Chas been sucked up.g) After 1-2 minutes, turn the main control to ON, so there is pressure in thecircuit.i) Open the section taps to spray the liquid in circuit washer tank C.k) Distribute the washing residue over a portion of the field where it will notcause damage.l) After you have finished washing, stop the diaphragm pump.NOTE: Before using the machine again for spraying, turn taps A and S backto the correct operating positionABDCFIG.
