— CALIBRATION
— AFTER SPRAYING
— WINTER STORAGE
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 wand and
boom. Refill the tank about half full with plain water and
use a chemical neutralizer such as Nutra-Sol® or equiv-
alent 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.
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 pumping a solution of RV antifreeze
through the entire plumbing. Proper care and main-
tenance will prolong the life of the sprayer.
— OPERATION
This sprayer is designed to be attached to an ATV rack
or other stable surface. The pumping system draws
solution from the tank, through the strainer and to the
pump. The pump forces the solution under pressure to
the spray wand and spray boom. 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 bypass valve located on the top of the
tank. Also, the boom can be cycled on and off with this
valve. See the illustration in this manual for more details
on using the bypass valve.
Regularly inspect the suction supply screen on the inside
of the tank. Flush with water to clear any accumulated debris.
WARNING: Some chemicals will damage the pump
valves if allowed to soak untreated for a long period
of time. Always flush the pump with water after use.
Do not allow chemicals to sit in pump for extended
times of idleness. Follow chemical manufacturers
instructions on disposal of all waste water from the
sprayer.
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 determine (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 indicates 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 number of seconds indicated
by the speed chart. Once you have reached the throttle
setting needed, mark the throttle location 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.

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.

Troubleshooting Guide —
Problem/Causes and Remedies:
Pump will not Start
Check:
• Correct voltage (±10%) and electrical connections
• Fuse or breaker
• Pressure switch operation and correct voltage at switch
• Rectifier or motor for open or grounded circuit
• Locked drive assembly
Pump will not Prime (No discharge with motor running)
Check:
• Debris in strainer
• Restriction (kinks) in inlet/outlet tubes
• Debris or swelling in inlet/outlet valves
Pump will not Shut Off (Output line closed and no leaks)
Check:
• Air trapped in outlet line or pump head
• Correct voltage to pump
• Debris in pump inlet/outlet valves
• Loose drive assembly or pump head screws
• Pressure switch operations/adjustments
Leaks from Pump Head or Switch
Check:
• Loose screws at switch or pump head
• Switch diaphragm ruptured or pinched
• Punctured diaphragm if fluid is present
Spray & Pump FAQs —
--Why does the pump not run all the time?
This is a demand pump and only runs with flow; spray wand, by-pass, spray tips or leak in system
--Why does the pump surge while using the spray wand?
Low flow may cause the pump to surge (or cycle). This could happen when the spray wand is adjusted for a small or fine spray
pattern. To overcome, slightly open the by-pass valve.
--How do I adust the pressure?
Pressure should be adjusted by regulating the by-pass valve (slightly opening or closing).
--What is the optimal operating pressure?
40 PSI - This can be accomplished by turning on the pump and adjusting the bypass valve until the gauge reads 40 PSI (or slightly
higher). The pump will run continuously. Ensure that the boom and/or handgun is not spraying while you set the pressure. The
pressure will drop slightly when the boom and/or handgun is operated.
--What pressure should the pressure gauge read?
Please refer to the operation instructions for boom operating pressures, varying boom pressures can be achieved by regulating or
adjusting the by-pass valve. Typically the spray wand will be operated between 20 and 40 PSI.
--What is the recommended PSI to inflate the tires?
30 PSI Max
--My pump quit and will not restart - what should I check?
Check all electrical connections. Ensure switch is in the on position. Check in-line fuse and/or fuse in car adapter end. Ensure
correct voltage +/- 10%. 12-13 volt
--Low flow or no flow at all - what should I check?
Check for a clogged suction hose and/or suction strainer. Often you will need to clean the suction strainer. Check for proper voltage.
--Is there a fuse for the sprayer?
Yes, either an in-line fuse, a fuse located in the car adapter housing or both.
--What size fuse should I use as a replacement?
7.5 amp
--What is the range of the spray wand?
35 feet max
--How should I clean the tank after use?
Tank should be cleaned with Nutrasol® or similar tank cleaning agent, and then rinsed with water.
--Is there an adjustment screw on the pump to adjust pressure?
Yes, please refer to the operation instructions, "Adjusting the Pressure Switch".
--How do I remove / replace fuse?
Unscrew in-line fuse connector, or unscrew the car adapter housing.
--Can the spray tip on the wand be replaced with a different type of tip?
Yes, however your wand comes with a #18 tip which is standard. Brass tips generally produce better spray patterns than plastic.
--Each time I turn on the pump my fuse blows.
1) Excessive voltage 2) Improper adjustment of the pressure switch 3) Damaged wiring harness.
--What is the warranty (time duration) on pump, tank, trailer pieces, and accessories?
1 year as stated in operation instructions.
--Pressure gauge reads 85 -90 psi before shutting off - should pump shut off at 60 psi?
Pump 7802 2.0 GPM comes preset from the factory to shut off at 60 PSI. Should this vary please see, "Adjusting the Pressure
Switch" in the operation manual. Turn on pump and hold spray wand open, slowing adjust until the pump shuts off at 60 PSI.
--Pump continues to run and surge when not spraying.
Ensure the by-pass is completely closed and your system has no leaks. Check by-pass hose to ensure no fluid is passing through the
valve while in the closed postion. If so replace valve.
WARNING - Ensure the wiring harness does not become pinched or damaged in any way. This may damage the pump or cause
the wiring harness to overheat, resulting in a melt down or fire.
