Full Internal Cleaning (Soak Wash)
μ
ATTENTION! Always use this cleaning procedure, if one or more of these situations occur:
A. There is risk of damage to the next crop sprayed, by sediments of the chemical just used.
B. Right away, the same chemical or crop not used for the sprayer.
C. Before carrying out any repair or maintenance job on the sprayer.
μ
ATTENTION! Always washing the sprayer between jobs with incompatible crops, 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 RinseTank and Rinsing Nozzles" on page 109).
2. Drive to the filling location.
3. Prepare sprayer for cleaning. Fill water in the MainTank to 10% of its capacity. Fill the RinseTank completely. Later you
use this water for rinsing.
4. Add the cleaning agent to the MainTank by using the TurboFiller. Follow instructions on the label of the cleaning agent.
5. Set suction SmartValve for "MainTank" and pressure SmartValve for "MainTank". 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 Emptying/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 on the inside.
11. Shut all three valves on the TurboFiller again.
12. Verify that all nozzles are closed. If not, press the main valve ON/OFF switch on the grip.
13. Set the pressure SmartValve for "Spraying".
14. Allow the liquid in the MainTank to circulate for minimum 3 minutes with the nozzles shut. Do this to clean the return
lines from boom to tank.
15. Set the pressure SmartValve for "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), in order to prevent spot contamination and accumulation.
Continue to spray until all liquid has exited from the boom pipes and nozzles.
17. Shut all nozzles with the main ON/OFF switch.
18. 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 MainTank.
19. Include rinsing of the TurboFiller in step 18. Operate all 3 valves during this process.
20. Disassemble all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and
detergent and a brush.
±
WARNING! It is the responsibility of the sprayer operator or owner to clean the sprayer sufficiently, to prevent
contamination of the environment, crop damage and health and safety hazards to the operator and the public.
HARDI cannot be held responsible for any damage or incidents related to insufficient cleaning.
μ
ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Clean manually with a high
pressure cleaner afterwards, especially if the next crop is sensitive to the chemical just sprayed!
