OPER ATION
OVERVIEW
The pumping system draws solution from the tank,
through the suction hose and into the pump. The
pump forces the solution under pressure through the
pump manifold, where it is directed to the spray wand
and (if equipped) the optional spray boom.
Regularly inspect the suction hose strainer inside
the tank. Flush with water to clear any accumulated
debris.
Relief Hose

n/off.
• Current weather and terrain conditions must be
considered when setting up the sprayer.
• Do not spray when wind speed exceeds 11 mph.
• Protective clothing must be worn when applying
some products. Be sure to read the chemical label
carefully.
SPRAY APPLICATION
Spray Wand: Maximum range 35'.
Accessory Spray Booms
PBA-22: 2-Nozzle Boom, 80" spray width.
PBA-77: 7-Nozzle Boom, 140" spray width.
For application rates, refer to the Accessory Spray
Boom Calibration section of this manual.
OPERATING PRESSURE
Optimal operating pressure is 40 psi. The pump has
a pressure switch that will shut off the pump when
pressure reaches 60 psi.
Typically the spray wand will be operated at between
20 and 40 psi. Refer to the Spray Boom Calibration
section for data on boom operating pressures.
To adjust the system pressure, make sure the wand
(and spray boom, if equipped) are turned OFF. Turn
the pump ON and adjust the BYPASS valve until the
gauge reads 40 psi. The pump will run continuously.
Once the spray wand or boom is activated, the
pressure will drop slightly.
CAUTION
Always use appropriate personal protective
equipment, including gloves and safety
goggles, when lling sprayer.
CAUTION
When using spray wand, never point it at
objects (i.e., humans, vehicles, etc.). Keep at
least 10 feet away from objects while using
the spray nozzle.

AFTER USE / MAINTENANCE / WINTER STORAGE
AFTER USE / CLEAN OUT
1. Fill the sprayer partway with water. Start the
sprayer and allow clear water to be pumped
through the sprayer plumbing system and out the
spray wand and the boom nozzles (if equipped).
2. Rell the tank about half full with plain water and
add a chemical neutralizer such as Nutra-Sol®or
equivalent. Pump the cleaning solution through
the sprayer plumbing system, spray wand, and
boom nozzles (if equipped). Flush the entire
sprayer with the neutralizing agent.
3. Follow the chemical manufacturer’s disposal
instructions for all wash or rinsing water.
WARNING
Some chemicals will damage the pump valves
if allowed to soak untreated for a long period
of time. Always ush the pump with water
after use. Do not allow chemicals to sit in
pump for extended times of idleness. Follow
chemical manufacturer's instructions on
disposal of all waste water from the sprayer.
CAUTION
Always use appropriate personal protective
equipment, including gloves and safety
goggles, when lling or emptying sprayer.
Cleaning Spray Boom Nozzles (If Equipped)
1. Remove the spray tips and screens from the
boom, Wash the tips thoroughly with water or
cleaning solution (appropriate for the chemical just
sprayed). Blow out the orice, clean and dry.
2. If the orice remains clogged, clean it with a ne
bristle brush (not a wire brush) or a toothpick,
taking care not to damage the orice. Water rinse
and dry the tips before storing.
MAINTENANCE
Fuse Replacement
The lead wire assembly includes an inline fuse. When
necessary, replace with a new 7A fuse.
WINTER STORAGE
Proper care and maintenance will prolong the life of
the sprayer.
1. Drain all water and chemical out of the sprayer
and clean as described in the "After Use/Clean
Out" section of this manual. Pay special attention
to pump and valves, as these items are especially
prone to damage from chemicals and freezing
temperatures.
2. The sprayer should be winterized before storage
by pumping a solution of RV antifreeze through
the entire plumbing system.
WARNING
Always shut vehicle OFF before attempting to
attach, detach, or service the sprayer.
WARNING
Do not operate a sprayer in need of
maintenance.

SPRAY & PUMP FAQs
• Why does the pump not run all the time?
This is a demand pump and only runs with ow
through the spray wand, by-pass valve, or spray
boom nozzles.
• Why does the pump surge while using the
spray wand?
Low ow may cause the pump to surge (or cycle).
This could happen when the spray wand is adjusted
for a small or ne spray pattern. To overcome this,
slightly open the bypass valve on the pump manifold.
• How do I adjust the pressure?
Operating pressure should be adjusted by regulating
the bypass valve. (See full instructions in the
Operation section.)
To adjust the pump OFF pressure setting, see full
instructions under "Adjusting the Pressure Switch" in
the Pump Specications & Information section.
• Can the spray tip on the wand be replaced with
a different type of tip?
Your wand comes with a #18 tip. It may be replaced
by other types of tip. Brass tips generally produce
better spray patterns than plastic.

ACCESSORY SPRAY BOOM CALIBRATION
Chemical product labels may show application rates
in gallons per acre, per 1000 ft2, or per 100 ft2. The
Spray Coverage tables show all three rates.
After determining how much mixed solution you
are going to spray for your job, select the spraying
pressure (psi) and spraying speed (mph) needed. You
will nd optimal spraying in the 20 to 30 psi range.
Adjust the boom height if needed to position the
nozzles 18" to 20" above the ground. For the best
spray pattern coverage, the nozzles may be rotated
rearward 15°.
To determine the ground speed of your sprayer,
measure and mark driving distances of 100, 200, or
300 feet. The table below indicates the number of
seconds needed to travel these distances. Set the
throttle and, with a rolling start, drive the measured
distance of your choice.
Adjust the throttle until you can match the number
of driving seconds needed. Mark the throttle setting
and note the gear range so you can use them while
spraying.
Add water and chemicals in the proper amounts in the
spray tank and drive to your starting point. When you
are ready to spray, turn the boom control valve OFF.
Once the pump is turned ON, the unit will begin
spraying. The system pressure will decrease slightly
as uid begins owing from the spray nozzles. This
is normal; the pressure will recover when the control
valve is turned OFF.

CAUTION
Always use appropriate personal protective
equipment, including gloves and safety
goggles, when lling sprayer.

Converting gal/acre to gal/1000 ft2
Most chemical labels indicate a chemical
application rate in 1,000 ft2.
If the rate on the chemical label is indicated in
gallons per acre, divide the per acre rate by 43.56
to convert to gallons per 1,000 ft2.
1 acre = 43,560 ft2
1 gallon per 1000 ft2= 43.56 gallons per acre
Other Conversion Factors
1  oz = 2 Tbl
1 cup = 8  oz
1 pint = 2 cups = 16  oz
1 quart = 2 pints = 32  oz
1 gallon = 4 quarts = 8 pints = 128  oz

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 downstream 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.
These pressure settings may vary in response to the
characteristics of the system in which the pump is
installed, the exibility and length of the tubing, the
faucet or valves and the duration that they are open.
Therefore, variation in pressure setting is expected
with use and over time.
Adjusting the Pressure Switch
Should the pressure sensing demand switch OFF
setting vary with use and time to an unsuitable value,
it may be adjusted for optimum performance. Turn
the set screw clockwise to increase the OFF pressure
setting and counterclockwise to decrease the setting.
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.

PUMP SPECIFICATIONS & INFORMATION
CAUTION
Do not operate pump in an explosive
environment. Arcing from the motor brushes
or switch, or excessive heat from an improperly
cycled motor, may cause an explosion.
CAUTION
To prevent electrical shock, disconnect power
before initiating any work. In the case of
pump failure, the motor housing and/or pump
uid may carry high voltage to components
normally considered safe.
Installation and Operation Precautions
• Always consider electrical shock hazard when
working with and handling electrical equipment.
Electrical wiring should only be done by a qualied
electrician per local and state electrical codes.
• Do not pump gasoline or other ammable liquids.
Pump head materials are designed for use with
water only. Do not use with petroleum products.
• 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).
• Never subject the pump to pressures above 125
psi (8.5 bars).
• The pump is equipped with a pressure sensing
demand switch that controls the maximum
operating pressure.
• As long as there is inlet water pressure, the pump
will not stop forward ow of water even if the motor
is turned off. Be sure the system has a positive
means of shutting off the water supply.
• Do not assume uid compatibility. If the uid is
improperly matched to the pumps’ elastomers, a
leak may occur.
Servicing
Every Year: Check the system against operating
standards.
Every 2 to 3 Years: We recommend replacing the
diaphragm and checking against operating standards.
Important Warranty Return Safety
Instructions
When you return your pump for warranty or repair, you
must always do the following:
• Flush chemical residue from the pump (best done
in the eld).
• Attach a tag to the pump identifying the type of
chemicals sprayed with that pump.
• Include complete description of the 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.
