Initial System Setup and Testing
19. Hold the MAN ADJ switch in the DEC position for approximately 12 seconds. This ensures the motorized
control valve is fully open.
20. Close the bypass #1 hand valve to set the desired minimum operating pressure.
Note:
The minimum pressure should be approximately half the normal spraying pressure. If the normal
spraying pressure is 30 psi [210 kPa], set the minimum pressure to approximately 15 psi [105
kPa).
Initial System Field Test
Note:
This procedure applies only to applications of 3 GPM [11 lit/min] or greater. For flow less than 3
GPM [11 lit/min], refer to the section for the alternate bypass line testing procedure.
1. Drive down the field at the target speed with the sprayer booms off to verify the SPEED readout in the
console.
2. Turn on the sprayer and booms.
3. Switch the RATE switch to RATE 1.
4. Increase or decrease the vehicle’s speed by one MPH [2 km/h].
Note:
The system should automatically adjust to the target application rate. If the system does not
perform the adjustment, perform the steps in. If the system is still not performing correctly, refer to
for possible causes and corrective action.
5. At the end of each row, switch the Master ON/OFF switch to OFF to shut off the flow. This also turns off the
area totalizer.
6. Verify the area covered and the volume used.
Alternate Bypass Plumbing Initial System Field Test
Note:
This procedure applies only to applications of less than 3 GPM [11 lit/min]. For flow of 3 GPM [11
lit/min] or greater, refer to the Initial System Setup section on page 39 for the main hose line
testing procedure.
1. Drive down the field at the target speed with the sprayer booms off to verify the SPEED readout in the
console.
2. Turn on the sprayer and booms.
3. Switch the MAN/AUTO switch to AUTO.
4. Increase or decrease the vehicle’s speed by 1 MPH [2 km/h].
Note:
The system should automatically adjust to the target application rate. If the system does not
perform the adjustment, perform the steps in the Alternate Bypass Plumbing Initial System Field
Test section on page 41. If the system is still not performing correctly, refer to Chapter 6
Preventative Maintenance and Troubleshooting for possible causes and corrective action.
5. At the end of each row, switch the Master ON/OFF switch to OFF to shut off the flow. This also turns off the
area totalizer.
6. Verify the area covered and volume used.
