In-field diluting of remaining spray liquid residues inthe spraying circuit for spraying the liquid in the field,before cleaning the sprayer.1. Empty the sprayer as much as possible. Turn theblue valve 6 towards pump and spray till air comesout of all nozzles.2. Remove the tank filter basket.3. Turn suction valve 2 towards rinsing tank.4. Turn pressure valves 5 towards rinsing nozzle(if fitted).5. Engage and set the pump at appr. 300 r.p.m.6. When rinsing water corresponding to appr. 10 timesthe spray liquid residue (see paragraph ìTechnicalResidueî) is used, turn back suction valve towardssuction from main tank and operate all valves, so allhoses and components are rinsed.7. Turn pressure valve 5 back to EC operating unit andspray liquid in the field you have just sprayed.8. Repeat point 3-7 until the rinsing tank is empty.B. Rinsing the pump, operating unit, spray lines, etc. incase of stop in spraying before main tank is empty (e.g.beginning rain etc.).1. Close ball valve under-neath the self-cleaningfilter.2. Turn suction valve 2 towards rinsing tank.3. Turn blue return valve 6 (if fitted) towards pumpsuction line.4. Engage the pump and spray water from rinsing tank inthe field until all nozzle tubes/nozzles are flushed withclean water.5. Disengage pump again.6. Open ball valve again.WARNING! The rinsing nozzles cannot alwaysguarantee a 100% cleaning of the tank. Alwaysclean manually with a brush afterwards, espe-cially if crops sensitive to the chemical just sprayed aregoing to be sprayed afterwards!TTTTTececececechnical Rhnical Rhnical Rhnical Rhnical ResidueesidueesidueesidueesidueInevitably a quantity of spray liquid will remain in thesystem, which cannot be sprayed properly on the crop,as the pump takes in air when the tank is about to beempty.This Technical Residue is defined as the remaining liquidqty. in the system as the first clear pressure drop on thepressure gauge is read.1) Residue in main tank, possible to dilute with water from rinsingtank2) Total residue in tank and spraying circuit on standard sprayer.Variations due to different ground inclinations etc.The dilutable residue must be diluted 10 times with cleanwater and sprayed to the crop just sprayed beforecleaning the sprayer - See paragraph ìCleaningî.T055-0016T026-0001xDHHHI HHQIh I E E P E Echart 016
