The pumping system draws solution from the tank, through
the strainer and to the pump. The pump forces the solution
under pressure to the boom nozzles and spray wand.
The pump has a pressure switch which will shut the pump
off when it reaches 60 PSI.
Pressure may be regulated by opening or closing the
valve located on the top of the tank. See “Valve Operation”
illustrated in this manual.
The nozzles on the boom will spray an 80 inch wide swath.
Check the nozzle spray pattern by spraying water on a con-
crete surface.
Regularly inspect the suction supply screen on the inside
of the tank. Flush with water to clear any accumulated debris.
Chemical labels may show application rates in gallons per
acre, gallons per 1000 square feet or gallons per 100 square
feet. You will note that the tip chart shows all three of these
rating systems.
Once you know how much you are going to spray then de-
termine (from the tip chart) the spraying pressure (PSI), and
the spraying speed (MPH).
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 carefully.
Determining the proper speed of the tractor can be done by
marking off 100, 200 and 300 feet. The speed chart indi-
cates the number of seconds it takes to travel the distances.
Set the throttle and with a running start travel the distances.
Adjust the throttle until you travel the distances in the num-
ber of seconds indicated by the speed chart. Once you have
reached the throttle setting needed, mark the throttle loca-
tion so you can stop and go again (returning to the same
speed).
Add water and proper amount of chemical to tank and drive
to the starting place for spraying.
When you are ready to spray, turn the boom valve to the
“on” position. This will start solution spraying from the tips
once the pump is turned on. The pressure will decrease
slightly when the boom is spraying.
After use, fill the sprayer part way with water. Start the
sprayer and allow clear water to be pumped through the
plumbing system and out through the spray nozzles.
Refill the tank about half full with plain water and use a chemi-
cal neutralizer such as Nutra-Sol® or equivalent and
repeat cleaning instructions. Flush the entire sprayer with
the neutralizing agent. Follow the chemical manufacturer’s
disposal instructions of all wash or rinsing water.
Remove tips and screens from the boom. Wash tips thor-
oughly with water or cleaning solution (appropriate for chemi-
cal used). Blow out orifice, clean and dry. If orifice remains
clogged clean it with a fine bristle (not wire) brush, or with a
tooth pick. Do not damage the orifice. Water rinse and dry
tips before storing.
Drain all water and chemical out of sprayer, paying special
attention to pump and valves. These items are especially
prone to damage from chemicals and freezing weather.
The sprayer should be winterized before storage by pump-
ing a solution of RV antifreeze through the
entire plumbing. Proper care and maintenance will prolong
the life of the sprayer.

Installation and Operation Precautions
yThe pump is equipped with a pressure sensing demand switch that controls the maximum
operating pressure.
yIn addition, never subject the pump to pressures above factory set/max pressure rating.
yAs long as there is inlet water pressure, the pump will not stop forward flow of water even if the
motor is turned o. Be sure the system has positive means of shutting o water supply.
yDo not operate pump in an explosive environment. Arcing from the motor brushes, switch or
excessive heat from an improperly cycled motor may cause an explosion.
yDo not locate the pump motor near low temperature plastics or combustible material. The
surface temperature of the motor may exceed 180°F (82°C).
yDo not pump gasoline or other flammable liquids. Pump head materials are designed for use
with water only. Do not use with petroleum products.
yDo not assume fluid compatibility. If the fluid is improperly matched to the pumps’ elastomers,
a leak may occur.
yTo prevent electrical shock, disconnect power before initiating any work. In the case of pump
failure, the motor housing and/or pump fluid may carry high voltage to components normally
considered safe. Therefore, always consider electrical shock hazard when working with and
handling electrical equipment. If uncertain, consult an electrician. Electrical wiring should only
be done by a qualified electrician per local and state electrical codes.
Servicing —
yEvery Year: Check system against operating standards. Flush with clean water and store in
warm dry place.
yEvery 2-3 Years: We recommend replacing the valves and checking against operating
standards.
Recommendations —
Electrical:
yThe ProFlo™ series pumps are designed for intermittent duty. Make sure that “OFF” periods are
sufficient. Consult the factory for particular data and design criteria.
yBe sure power supply used is adequate for the application.
yPump and motor specifictions are based on an alternator charged battery (13.6 VDC)
yUse sufficient battery supply power. UTV and lawn tractor batteries may aect pump
performance due to low voltage and amp ratings
yRapid On/O Cycling must be limited to no more than 6 times per minute, even
if the pump is operating in the Continuous Duty zone. Cycling could cause the
motor to heat beyond the recommended maximum temperature, and reduce the
operational life of the pump and pressure-sensing switch.
Important return safety instructions -
When returning your pump for warranty or repair, you must always do the following:
yContact factory for RMA number.
yFlush chemical residue from the pump (best done in the field).
yTag pump with type of chemicals having been sprayed.
yInclude complete description of operation problem, such as how pump was used, symptoms of
malfunction, etc. Since pumps can contain residues of toxic chemicals these steps are
necessary to protect all the people who handle return shipments, and to help pinpoint the
reason for the breakdown.
