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 inside.
11.
Shut all three valves on the TurboFiller again.
12.
Verify that all nozzles are shut on 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. This is done 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). Spot contamination and accumulation must be prevented.
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, that the sprayer is cleaned sufficiently to prevent
contamination of the environment, crop damages and health and safety hazards to the operator and the public.
HARDI cannot be held responsible for any damages 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!
