Full Internal Cleaning (Soak Wash)
ATTENTION! This cleaning procedure is always used, if one or more of these situations occur:
A. The next crop to be sprayed is at risk of being damaged by the chemical just used
B. The sprayer is not going to be used right away for the same chemical or crop
C. Before any repair or maintenance job is going to be carried out on the sprayer.
ATTENTION! Washing the sprayer between jobs with incompatible crops must be done according to prescriptions
from the chemical manufacturer. Use a commonly used cleaning agent. If your chemical prescribes a different
cleaning agent and/or another cleaning procedure, you must follow that.
Procedure for Washing with a Cleaning Agent
1. Rinse the sprayer in the field (see the section "Use of Rinsing Tank and Rinsing Nozzles" on page 130).
2. Drive to the filling location.
3. Prepare sprayer for cleaning. Fill water in the main tank to 10% of its capacity. Fill the rinsing tank completely. This water
is later used for rinsing.
4. Add the cleaning agent to the main tank by using the TurboFiller. Follow instructions on the label of the cleaning agent.
5. Set suction SmartValve for "Main tank" and pressure SmartValve for "Main tank". Set agitation valve for "Full agitation".
6. Engage and set the pump speed at approximately 300 rpm.
7. Allow the liquid to circulate the system for 3 minutes.
8. Set the pressure SmartValve for "Pressure Empty/TurboFiller" for minimum 10 seconds without activating the
TurboFiller in order to burst and flush the safety valve.
9. Open the TurboFiller transfer valve and the deflector valve. Allow the liquid to circulate for 3 minutes.
10. Close the lid and activate the container rinsing valve to clean the hopper inside.
11. Shut all three valves on the TurboFiller again.
12. Set the SmartValve for "FastFiller flushing" for 3 minutes to clean the FastFiller lines.
13. Verify that all nozzles are shut on the main valve ON/OFF switch on the grip.
14. Set the pressure SmartValve for "Spraying".
15. Allow the liquid in the main tank to circulate for minimum 3 minutes with the nozzles shut. This is done to clean the
return lines from boom to tank.
16. Set the pressure SmartValve for "Tank cleaning nozzles". Allow the liquid to circulate for 3 minutes.
17. Spray out water with cleaning agent and chemical residue.
Set the spray pressure at 3-5 bar.
Note that the washing water still contains active chemical and choose an appropriate area to spray this out.
Alternatively, the washings can be dumped at the filling/washing location and retained in an appropriate receptacle
(e.g. slurry tank or similar). Spot contamination and accumulation must be prevented.
Continue to spray until all liquid has exited from the boom pipes and nozzles.
18. Shut all nozzles with the main ON/OFF switch.
19. Rinse the sprayer again with clean water to rinse out all remains of the cleaning agent. This prevents the cleaning agent
remaining in the fluid system, which could damage the next spray chemical filled into the main tank.
20. Include rinsing of the TurboFiller in step 18. Operate all 3 valves during this process.
21. Dismantle all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and
detergent and a brush.
