— ASSEMBLY INSTRUCTIONS
Tools required:
1 — 9/16” End Wrench
1 — Thread Sealant
— OPERATION
This sprayer is designed to be attached to a 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.
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. The more it is opened, the lower the pressure will be.
Regularly inspect the suction supply screen on the inside of the tank. Flush with water to clear any accumulated debris.
— AFTER 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 wand.
Refill the tank about half full with plain water and use a chemical 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.
— WINTER STORAGE
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 maintenance will prolong the life of the sprayer.
Follow chemical manufacturers instructions on disposal of all waste water from the sprayer.

Pressure Sensing Demand Switch —
The PowerFLO Series 7800 pump is controlled by a built-in pressure sensing demand switch. When a faucet or valve is opened down stream of the pump, line pressure drops thus starting the pump automatically.
Conversely, when the valve shuts, the line pressure increases turning the pump off automatically. The pressure switch actuates in response to the pump outlet pressure at a predetermined and preset pressure. The pump label indicates the predetermined ON and OFF pressures. Typically, the OFF pressure is accurately set at the Factory and the ON pressure is within an allowable range below that value. In response to the characteristics of the system in which the pump is installed, the flexibility and length of the tubing, the faucet or valves and the duration that they are open; these pressure settings may vary. Therefore, variation in pressure setting is expected with use and over time.
Adjusting the Pressure Switch:
Should the pressure switch OFF setting vary with use and time to an unsuitable value, it may be adjusted for optimum performance. Turn the setscrew clockwise to increase the OFF pressure setting and counter clockwise to decrease. The screw should not be adjusted more than one half turn without consulting the Factory. Excessive adjustment of the pressure switch could cause low system pressure, rapid cycling ON/OFF operation, and reduced pump and motor life. Damage may occur. The
Warranty does not cover improper adjustment of the pressure switch.
Installation and Operation Precautions —
1. The pump is equipped with a pressure sensing demand switch that
controls the maximum operating pressure.
2. In addition, never subject the pump to pressures above 125 PSI
(8.5 bars).
3. As long as there is inlet water pressure, the pump will not stop
forward flow of water even if the motor is turned off. Be sure the
system has positive means of shutting off water supply.
4. Do 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.
5. Do not locate the pump motor near low temperature plastics or
combustible material. The surface temperature of the motor may
exceed 250°F (120°C).
6. Do not pump gasoline or other flammable liquids. Pump head
materials are designed for use with water only. Do not use with
petroleum products.
7. Do not assume fluid compatibility. If the fluid is improperly
matched to the pumps’ elastomers, a leak may occur.
8. To 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 —
Every Year: Check system against operating standards.
Every 2-3 Years: We recommend replacing the diaphragm and checking against operating standards.
* Important return safety instructions:
When you return your pump for warranty or repair, you must always do the following:
1. Flush chemical residue from the pump (best done in the field).
2. Tag pump with type of chemicals having been sprayed.
3. Include 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.

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 adjust 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.
--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, and accessories?
2 years as stated in operation instructions.
--Pressure gauge reads 85 -90 psi before shutting off - should pump shut off at 60 psi?
Pump 7802 2.2 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 position. 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.
