If using 8 nozzles (4/side) with two turned off due to a smaller canopy then each nozzle needs to
deliver 1.25 l/min. From the HCC nozzle chart HCC015 (Yellow) at 13 Bar pressure will give the
desired output. An alternative nozzle would be the HCC02 at approximately 7 Bar to give an
equivalent output.
