•
Commence driving the vehicle at the speed determined during calibration to achieve the required spray
outcome.

Quick Fill Kit
Where required, the TopCrop can be filled with water directly from a dam or river using the optional Quick
Fill Unit as follows, refer to Figure 9:
NOTE: The Quick Fill Unit requires some water in the tank to operate
the venturi hydro injector.
•
Ensure there is at least 30 litres of water already in the tank, as this is required to create the venturi
effect.
•
Open the lid on the tank, to allow venting when the venturi hydro injector is operating.
•
Position the TopCrop unit close to the water supply, such that the water is less than 2m lower than the
top of the TopCrop tank’s venturi hydro injector.
•
Connect the 6m suction hose to the venturi hydro injector, placing the floating filter end into the water.
•
Start the pump as described above.
•
At the pump discharge manifold, open the valve to the hose connecting the pump to the venturi hydro
injector. Water will start pumping to the injector, which will create the venturi effect to draw water from
the supply into the tank.
