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, or
B. The sprayer is not going to be used right away for the same chemical or crop right away, or
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 instructions
from the chemical manufacturer. Use e.g. AllClearExra, 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 “Use of Rinse Tank and Rinsing Nozzles” on page 75).
2. Drive to the filling location. Prepare sprayer for cleaning with cleaning agent. Fill water in the main tank to 10% of its
capacity. Fill the rinse tank completely. This water is later used for rinsing.
3. Turn suction SmartValve to and the pressure SmartValve to with all sections off. Set agitation valve to “Full
agitation”.
4. Engage and set the pump speed at approximately 300 r.p.m. or 560 r.p.m. (depending on pump type).
5. Allow the liquid to circulate in the system for 3 minutes.
6. Close Agitation valve (no agitation) and turn the pressure SmartValve to unused function (or “TurboFiller” without
activating) for a minimum of 10 seconds in order to burst and flush the safety valve.
7. Open the TurboFiller transfer valve and the deflector valve. Allow the liquid to circulate for 3 minutes.
8. Close the TurboFiller lid and activate the container rinsing valve to clean the hopper inside.
9. Shut off all three valves on the TurboFiller again.
10. Verify that all nozzles are shut at the main ON/OFF button on the grip.
11. Turn the pressure SmartValve to .
12. 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.
13. Turn the pressure SmartValve to . Allow the liquid to circulate for 3 minutes.
14. Spray out water with cleaning agent and chemical residue. Set the spray pressure at 45-75 psi (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 “Filling/washing location requirements” on page 60 for more information. Spot contamination and
accumulation must be prevented. Continue to spray until all liquid is expelled from the boom tubes and nozzles.
15. Shut off all nozzles by the main ON/OFF switch.
16. Rinse the sprayer again with clean water to rinse out all remains of the cleaning agent - see “Use of Rinse Tank and
Rinsing Nozzles” on page 75. This is to remove the cleaning agent from the fluid system, which could contaminate the
next spray chemical filled into the main tank.
17. Include rinsing of the TurboFiller in step 16. Operate all 3 valves during this process.
18. Dismantle all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and
detergent.

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.
˜
ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually with a
brush afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed afterwards!
