Full Internal Cleaning (Soak Wash)

μ
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.
μ
ATTENTION! Washing the sprayer between jobs with incompatible crops must be done according to prescriptions
from the chemical manufacturer. Use e.g. AllClearExtra, as this is a commonly used cleaning agent. If your chemical
prescribes another cleaning agent and/or another cleaning procedure, you must follow that.
Procedure for washing with a cleaning agent, such as AllClearExtra:
1. Rinse the sprayer in the field (See the section "Use of Rinsing Tank and Rinsing Nozzles").
2. Drive to the filling location.
3. Prepare sprayer for cleaning with cleaning agent. Fill water in the main tank to 10% of its capacity. Fill the rinsing tank
completely. This water is later used for rinsing.
4. Turn suction SmartValve towards "Main tank" and pressure SmartValve towards "Main tank". Set agitation valve to "Full
agitation".
5. Engage and set the pump speed at approximately 300 rpm. Engage auxiliary pump (FlexCapacity configurations only).
6. Allow the liquid to circulate the system for 3 minutes.
7. Turn the pressure SmartValve towards "Pressure Empty/TurboFiller" for minimum 10 seconds without activating the
TurboFiller in order to burst and flush the safety valve.
8. Open the TurboFiller transfer valve and the deflector valve. Allow the liquid to circulate for 3 minutes.
9. Close the lid and activate the container rinsing valve to clean the hopper inside.
10. Shut off all three valves on the TurboFiller again.
11. Turn the agitation valve towards "FastFiller flushing" for 3 minutes to clean the FastFiller lines.
12. Verify that all nozzles are shut at the main ON/OFF button on the grip.
13. Turn the pressure SmartValve towards "Spraying".
14. 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.
15. Turn the pressure SmartValve towards "Tank cleaning nozzles". Allow the liquid to circulate for 3 minutes.
16. 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) - see
the section "Filling/washing location requirements" for more information. Spot contamination and accumulation must
be prevented. Continue to spray until all liquid has exited from the boom tubes and nozzles.
17. Shut off all nozzles by the main ON/OFF switch.
18. Rinse the sprayer again with clean water to rinse out all remains of the cleaning agent - see the section "Use of rinsing
tank and rinsing nozzles" on page 104". This to prevent that the cleaning agent remains in the fluid system, which could
damage the next spray chemical filled into the main tank.
19. Include rinsing of the TurboFiller in step 17. Operate all 3 valves during this process.
20. Dismantle all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and
detergent.
