Function of the front 2-way valve (Fig. 10)
Position: “Machine cleaning”
Pump conveys fresh water from the fresh water tank
through the spray nozzles to the injectors and via the
recycling filter back into the spray liquid tank.
Position: “Suction tank”
Pump conveys spray liquid from the spray liquid tank
to the spray nozzles.
The second 2-way valve is situated between pres-
sure regulator and pump – see also functional dia-
gram.
Note:
Both 2-way valves (Fig. 9 + Fig. 10) must always be in some po-
sition, either for spaying or for cleaning.
That means, e.g. both valves in position “suction tank” or in posi-
tion “machine cleaning”.
