Adjustments of EC Operating Control Unit
Before spraying the EC operating unit is adjusted using
clean water (without chemicals).
NOTE! To understand how to activate each func-
tion using the Pilot controller, please carefully read
your Pilot Operators Manual for detailed instructions
1. Choose the correct nozzle for the spray job by turning
the TRIPLET nozzle bodies. Make sure that nozzles
are the same type and capacity. See "Spray Tech-
nique" book for selection guidelines.
2. Turn main ON/OFF switch to ON.
3. Activate distribution valves so all sections are turned
ON.
4. Activate Pressure regulation switch C until emer-
gency handle (3 Fig 15) stops rotating (min pres-
sure).
5. Put the tractor in neutral and adjust the P.T.O. and
thereby the number of revolutions of the pump
corresponding to the intended travelling speed.
Remember the number of revolutions on the P.T.O.
must be kept between 300-600 rpm.
6. Pressure regulation switch C is activated until the
required pressure is shown on the pressure gauge.

Adjustment of Pressure Equalisation

1. Close the first section distribution valve.
2. Turn the first adjusting screw (C1 Fig 14) until the
pressure gauge again shows the same pressure.
3. Adjust the other sections of the distribution valve in
the same way.
NOTE! After initial adjustment of Pressure Equalisation,
further adjustment will only be needed when:
1. You change to nozzles of different capacities.
2. The nozzle output increases as the nozzles wear.
