Section Bypass Valves
The section bypass valves are used to adjust the
sprayer system pressure to the section valves to
ensure that the sprayer pressure to the spray section
remains constant no matter how many spray sections
are on (Figure 20).
Note:
Use the bypass valves when spraying in the
manual mode (open loop) only.

Section-Bypass Shutoff Valve
Use the section-bypass shutoff valve to control fluid
flow from the section bypass valves to the tank when
spraying in the manual mode (open loop); refer to
Figure 20.
Note:
Close the section-bypass shut off valve when
spraying in the application rate mode (closed loop).
Anti-Siphon Fill Receptacle
At the front of the tank cover is a hose receptacle
with a threaded fitting, a 90-degree barbed fitting,
and a short hose, which you can direct toward the
tank opening. This receptacle allows you to connect
a water hose to it and fill the tank with water without
contaminating the hose with the chemicals in the tank.
Important:
Do not lengthen the hose to allow
contact with the tank fluids. The distance from
the end of the hose to the uppermost water level
should be within local regulatory limits.

Tank Cover
The tank cover is located in the center, top of the tank.
To open the cover, shut off the engine, turn the front
half of the cover to the left, and swing it open. You can
remove the strainer inside for cleaning. To seal the
tank, close the cover and rotate the front half toward
the right.
