With your pump (Not Included) mounted
on the ‘top’ of your tank this is how your
bypass line will be configured.
You may need to punch or drill the hole
for your return line, approx. 7/8”.
With your pump (Not Included)
mounted on the ‘side’ of your
tank this will be your plumbing
configuration/setup.
You may need to punch or drill
the hole for your return line,
approx. 13/16”.
Testing the Sprayer
NOTE:
It is VERY important for you to test your sprayer with plain water before actual
spraying is attempted. This will enable you to check the sprayer for leaks without
the possibility of losing any expensive chemicals.
Fill the tank about 1/2 full with plain water and drive to the starting place for spraying.
When you are ready to spray, turn the boom valve to the “on” position (Detail A). This will start
solution spraying from the tips of the boom. The pressure will decrease slightly when the boom
is spraying.
Adjust the pressure by turning the “ON/OFF” valve lever on the bypass line valve (Detail B).
Make sure your pattern is sufficient. You may down-pressure the system by ‘bypassing’ solu-
tion back into the tank. This is achieved by opening the bypass valve. Regulating pressure is
done in this manner.
Read the operating instructions and initially begin spraying by closing the ‘Pressure Adjust’
valve and opening the boom line valve (Detail A). This will enable the air in the line to be elimi-
nated (purged) through all the tips, while building pressure. When everything tests all right (no
leaks and good pressure), add the desired chemicals to the mixture and water combination
and start your spraying operation. Adjust the pressure and spray as you did in the testing pro-
cedure.
Conditions of weather and terrain must be considered when setting the sprayer. Do not spray
on windy days. Protective clothing must be worn in some cases.
Be sure to read the chemical label(s) before application!
Operation
Fill the tank part way with water and then add the desired amount of chemical to be sprayed.
Finish filling tank to proper level. Turn the pump on and by depressing the “-” side of the rocker
switch. The pump is equipped with a pressure switch that is pre-set at the factory to shut the
pump off when all discharges are closed.
The pump will turn back on when one of the following actions occurs:
Boom valve is opened to broadcast spray with the boom.
Bypass valve is opened to re-circulate solution back into the tank.
When spraying with the boom, pressure may be reduced by slowly opening the bypass valve
until desired pressure is achieved. Opening the valve decreases pressure, closing the valve
increases pressure. When spraying with the boom, the proper method to set the pressure is to
open the boom valve completely and if a lower pressure is desired, then slowly open the by-
pass valve until that pressure is obtained.
For the safest and most efficient chemical application, you will need to calibrate your sprayer
using the tip and speed charts. Once you have determined the proper speed and pressure
settings, you will need to consult your chemical label for the amount of chemical to be added
to the tank. Read the entire label. Use only according to label directions.
