The 200 l rinsing tank can be used for two different
purposes.
A. In-field diluting of remaining spray liquid residues in
the spraying circuit for spraying the liquid in the field,
before cleaning the sprayer.
1. Empty the sprayer as much as possible. Turn the
blue valve 6 towards pump and spray till air comes
out 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 times
the spray liquid residue (see paragraph "Technical
Residue") is used, turn back suction valve towards
suction from main tank and operate all valves, so all
hoses and components are rinsed.
7. Turn pressure valve 5 back to EC operating unit and
spray 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. in
case of stop in spraying before main tank is empty (e.g.
beginning rain etc.).
1. Close ball valve under-
neath the self-cleaning
filter.
2. Turn suction valve 2 towards rinsing tank.
3. Turn blue return valve 6 (if fitted) towards pump
suction line.
4. Engage the pump and spray water from rinsing tank in
the field until all nozzle tubes/nozzles are flushed with
clean water.
5. Disengage pump again.
6. Open ball valve again.
WARNING! The rinsing nozzles cannot always
guarantee a 100% cleaning of the tank. Always
clean manually with a brush afterwards, espe-
cially if crops sensitive to the chemical just sprayed are
going to be sprayed afterwards!

Inevitably a quantity of spray liquid will remain in the
system, which cannot be sprayed properly on the crop,
as the pump takes in air when the tank is about to be
empty.
This Technical Residue is defined as the remaining liquid

qty. in the system as the first clear pressure drop on the
pressure gauge is read.
D u l i a t b e l
T t o l a e r s
1) Residue in main tank, possible to dilute with water from rinsing
tank
2) 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 clean
water and sprayed to the crop just sprayed before
cleaning the sprayer - See paragraph "Cleaning".
