Choosing nozzle discs
Before commissioning the liquid fertiliser system
you must choose and install the nozzle discs
in accordance with working width and placing
quantity.
This adaptation is necessary to achieve uniform
pressure and quantity distribution, irrespective
of the hose length.
The nozzle discs are installed in the nozzle
body on the coulters and marked with colour for
identification of the flow rate.
