21. Interruption of spraying process
If the spraying process will be interrupted e.g. due to weather condi-
tions, all parts which were in contact with spraying agent like pump,
spraying pipes, fittings and filters should be cleaned on the spraying
ground.
Normally a length of the run of 20 m is sufficient.
This cleaning avoids blockage of filters and nozzles.
Set the 3-way valve (1) to the middle position “Clean suction
filter” (Fig. 30a). This will shut-off the agent spraying circuit.
Set both 2-way valves (2+3) to position “Machine cleaning” (Fig.
30a/b). The pump will bring fresh water from fresh water tank to
the spraying nozzles.
Shut-off Recycling procedure on control box.
This will avoid, that cleaning liquid will be pumped through recy-
cling injectors back to the spray liquid tank, thus thinning the liq-
uid in the spray liquid tank.
Switch on pump, water from fresh water tank is now cleaning all
fittings, filters close to the spraying nozzles and the nozzles
themselves.
The cleaning liquid must be disposed on agricultural / forested /
horticultural surface.
