Residual quantities
A differentiation is made between two types
of residual quantities:
¾
Excess residual quantity after the end of
spraying operation, e.g. resulting from errors
in the calculation of the application quantity,
in filling or spraying operation.
¾
Technical residual quantities , which still
remain in the spraying mixture container, the
suction fitting and in the spraying line after
a considerably drop in spraying pressure.
The suction fitting consists of the assembly
groups: switch-over ball valves, short lines
and pump.
Technical residual quantities
Make sure that the residual quantity in the spray-
ing line will be placed in the form of undiluted
concentration. This is the case when switching
to fresh water with the nozzles activated.
Strictly spray this residual quantity from the
spraying line on an untreated area. The residu-
al quantity in the spraying line depends on the
width of the boom.
Required travel distance in [m] to spray out the
undiluted residual quantity in the spraying line
for all working widths:
[l/ha] [m]
100 [11 gal] 83 [272 ft]
150 [16 gal] 55 [180 ft]
200 [21 gal] 41 [134 ft]
250 [27 gal] 33 [108 ft]
300 [32 gal] 28 [91 ft]
400 [43 gal] 20 [65 ft]
Example:
With an application quantity of 200 l/ha [21 gal/
ac] the travel distance to spray out the residual
quantity is approx. 41 m [134 ft].
Draining technical residual
quantities
NOTE
Make sure that the residual quantity in the
spraying line will be sprayed out in the form of
undiluted concentration.
¾
Spray this residual quantity from the spraying
line on an untreated area.
¾
Refer to the chapter Technical residual quantities
for the travel distance required to spray the
residual quantity in the spraying line. The
residual quantity in the spraying line depends
on the working width of the folding boom.
¾
Once the residual quantity in the spraying
mixture container has reached a level of just
100 litres [26 gal] switch off the agitator to
spray the spraying mixture container empty.
With the agitator switched on the technical
residual quantity increases in contrast to the
specified values.
With the water system Basic Pro and CCS
Pro the agitator is automatically deactivated
at a spraying mixture cont ainer content of
less than 150 litres [40 gal]. With other water
systems, the agitator must be switched off via
the corresponding ball valves.
¾
Measures to protect the user must be applied
when emptying residual quantities. Follow
the instructions of the crop protection agent
manufacturers and wear personal protective
outfits.
¾
Dispose of the collected residual quantity
of spraying mixture in accordance with the
relevant statutory regulations.
¾
Collect the residual quantity of spraying mix-
ture in suitable containers.
¾
Dispose of the residual quantity of spraying
mixture with the stipulated waste disposal.
