4 - Sprayer Setup
Liquid System
Adjustment of EVC Operating Unit
Adjust the EVC operating unit before spraying, using only clean water
(without chemicals).
1. Choose the correct nozzle for the spray job by turning the TRIPLET
nozzle bodies. Make sure that all nozzles are of the same type and
capacity. See the "Spray Technique" book.
2. Set the main ON/OFF switch to ON at the spray control unit.
3. Turn all distribution valve switches ON at the spray control unit.
4. Press down the pressure regulation switch at the spray control unit
until the emergency handle on the valve stops rotating (minimum
pressure).
5. Put the tractor in neutral and adjust the PTO and thereby the
number of revolutions of the pump corresponding to the intended travelling speed. Remember to keep the number
of revolutions of the PTO between 300-600 rpm (pump 540 rpm) or 650-1100 rpm (pump 1000 rpm).
6. Push up the pressure regulation switch at the spray control unit, until the required spray pressure is shown on the
pressure gauge.
Adjustment of pressure equalization:
7. Close the first section valve on the spray control unit.
8. Turn the adjusting screw for the corresponding valve, until the pressure gauge shows the same pressure as when all
sections were open.
9. Open the section valve again.
10. Adjust the next section valves in the same way.
μ
ATTENTION! Hereafter adjustment of pressure equalization will only be needed when:
• you change to nozzles with other capacities
• the nozzle output increases, as the nozzles wear out
