After the main tank (7) has been filled with
water, the switchover valve (C) is switched
to the main tank.
The spray pump (H) draws the spraying
fluid from the main tank (7) via the swit-
ching valve (C), the selection valve (A) and
the suction filter (9). The spraying fluid is
pumped to the closed part-width sections
via the diverting valve (D) and the pressure
filter (3). The spraying fluid continues to
flow via the central bypass valve (21) into
the agitator (5) and helps stir the spraying
fluid.
The circulating spraying fluid cleans the
piping system.
As soon as spraying fluid is present in the
main tank (7), the stirring pump (I) draws
the spraying fluid via the selection valve
(B) and the suction filter (9) from the main
tank. The spraying fluid is then fed into the
main tank via the agitator control (E) and
the agitator (5). The liquid is diluted by cir-
culating the spraying fluid while the main
tank is being cleaned with clean water.
