D: Full internal cleaning (Soak wash)
÷
Note: This cleaning procedure is always used when:
A.
The next crop to be sprayed is at risk to be damaged by the chemical just used, or
B.
The sprayer is not going to be used again for same chemical or crop right away, or
C.
Before any repair or maintenance job is going to be carried out on the sprayer.
÷
Note: Washing of the sprayer between jobs with incompatible chemicals must be done according to instructions
from the chemical producer. Use e.g. AllClearExtra, as this is a commonly used cleaning agent. If your chemical
manufacturer suggests another cleaning agent and/or another cleaning procedure, you must follow that.
Procedure for wash with a cleaning agent, e.g. AllClearExtra:
1.
Rinse the sprayer in the field (See “A. Full internal rinsing” on page 58).
2.
Drive to farm fill station.
3.
Prepare sprayer for cleaning with cleaning agent, e.g. AllClearExtra. Fill water in the main tank to 10% of capacity (Fill
the rinse tank completely. This water is used later for rinsing).
4.
Turn on the Main Tank Valve.
5.
Turn on the Agitation Valve.
6.
Engage the pump.
7.
Allow the liquid to circulate for 3 minutes.
8.
Turn the Chemfiller/Ejector valve towards the Chemfiller.
9.
Open the TurboFiller deflector valve and allow liquid to circulate for 3 minutes.
10.
Close the lid and activate the container rinsing valve to clean the inside of the hopper.
11.
Shut off container rinsing valve and the deflector valve on the TurboFiller.
12.
Verify that all Boom nozzles are shut off.
13.
Turn the Chemfiller/Ejector valve towards “Spraying”.
14.
Allow the liquid in the main tank to circulate for a minimum of 3 minutes with the nozzles off to clean the return lines
from the boom to the tank.
15.
Spray out water with cleaning agent and chemical residue. Set the spray pressure at 45 - 70 psi (3-5 bar). Note that the
washing water still contains active chemical and choose an appropriate area to spray it out. Alternately, the washing
water 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 avoided. Continue to spray until all liquid is expelled from the
boom tubes and nozzles.
16.
Shut off all nozzles with the main ON/OFF switch.
17.
Rinse the sprayer again with clean water to rinse out all remains of the cleaning agent (See “A. Full internal rinsing” on
page 58). Do this to remove the cleaning agent from the fluid system, which could damage the next spray chemical
filled into the main tank.
18.
Include rinsing of the TurboFiller. Operate all 3 valves during this process.
19.
Remove all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and
detergent.
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!
÷
Note: It is the responsibility of the sprayer operator or owner that the sprayer is cleaned sufficiently to avoid
contamination of the environment, crop damages and health & safety hazards to operator and the public. HARDI®
cannot be held responsible for any damages or incidents related to insufficient cleaning.
