Agitation Adjustment
Refer to Figure 22
The agitation valve is used to adjust the pressure
to the agitation nozzles in the tank. Refer to the
agitation gauge, and adjust the pressure to a de-
sired rate. Different chemicals require different
agitation pressures to keep the chemical in
suspension.
!
CAUTION
If using liquid fertilizer or any other chemical that will
corrode brass, install a gauge protector under the
brass agitation gauge or plug the gauge hole. Failure
to do so will eventually cause the gauge to fail and
chemical to be expelled from the gauge.

tion being sprayed.
