Plumbing Overview
Refer to Figure 12
A basic knowledge of how the sprayer is plumbed helps
you understand how to operate your Great Plains
Sprayer. Throughout this manual, the components on
this diagram are described with the terminology labeling
these components.
Five of the valves are labeled on the sprayer decals.
Other key components are:
Valves operate by moving their handles to point at the
function on the decal, or toward the pipe desired on an
otherwise unmarked selector valve. Shut-off valves are
open when the handle is parallel to the piping, and
closed when the handle is perpendicular.
In normal spraying operations, fluid is drawn from the
main tank via the Left sump
and passes through the
pump.
From the pump, fluid passes through the Solution Whirl-
filter®
, which filters out or grinds up all undissolved
chemical and solid particles. The fluid then passes
through both the flow meter
and the bypass control
butterfly valve .
The bypass control butterfly valve controls how much
fluid goes to the boom. This is regulated by the Raven
SCS 440 controller. The fluid passes through the flow
meter
and proceeds to the 3-Way Boom Manifold
valves. If a boom valve is on, the fluid passes to its
respective boom section and is sprayed out the individual
nozzles.
The agitation is set by adjusting the agitation pressure
valve
while the pump is at operating speed. Refer to
Application Guide to adjust the agitation.
The optional inductor provides convenient pump-
driven loading of concentrates into the main tank.
There are tank shut off valves ( , , ) at each inlet
and outlet. Use these to prevent spills and isolate any
leaks.
To operate a correctly connected hydraulic pump, push
the hydraulic lever in the “down” position. When you want
to stop the pump, put the hydraulic lever in the “float”
position.
IMPORTANT !
Do not move the hydraulic lever to the neutral position
while the hydraulic pump is running. To do so may
cause damage to the hydraulic pump.
