OPERATION

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 sprays 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 concrete surface.
Regularly inspect the suction supply screen on the inside of the tank. Flush with water to clear any accumulated debris.

Most chemical labels indicate a chemical application ate in 1,000 sq. ft.; if the rate on the label is indicated as
a rate pe acre, divide the per acre rate by 43.56 to convert to a rate per 1,000 q. ft
1 Acre = 43,560 sq. ft.
1 gallon per 1,000 sq. ft. = 43.56 gallons per acre
1 fl. Oz. = 2 tablespoons
1 cup = 8 fl. Oz.
1 pint = 2 cups = 16 fl. Oz.
1 quart = 2 pints = 32 fl. Oz.
1 gallon = 4 quarts = 8 pints = 128 fl. oz.

CALIBRATION

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 journey 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.

AFTER SPRAYING

After use, fill the sprayer partway 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 chemical neutralizer such as Nutra-Sol® or equivalent and repeat cleaning instructions. Flush the entire sprayer with  the ineutralizing agent. Follow the chemical manufacturer’s disposal instructions of all wash or rinsing water.

Remove tips and screens from the boom. Wash tips thoroughly with water or cleaning solution (appropriate for chemicals used). Blow out orifice, clean and dry. If the orifice remains clogged clean it with a fine bristle (not wire) brush, or with a toothpick. Do not damage the orifice. Water rinse and dry tips before storing.

WINTER STORAGE

Drain all water and chemical out of the sprayer, paying special attention to the 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.
WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer. www.P65Warnings.ca.gov

Installation and Operation Precautions

• The pump is equipped with a pressure sensing demand switch that controls the maximum operating pressure.
• In addition, never subject the pump to pressures above factory-set/max pressure rating.
• As long as there is inlet water pressure, the pump will not stop the forward flow of water even if the motor is turned off. Be sure the system has positive means of shutting off the water supply.
• 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.
• Do not locate the pump motor near low temperature plastics or combustible material. The surface temperature of the motor may exceed 180°F (82°C).
• Do not pump gasoline or other flammable liquids. Pump head materials are designed for use with water only. Do not use petroleum products.
• Do not assume fluid compatibility. If the fluid is improperly matched to the pumps’ elastomers, a leak may occur.
• 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 hazards 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. Flush with clean water and store in a warm dry place.
• Every 2-3 Years: We recommend replacing the valves and checking against operating standards.

Recommendations

Electrical:

• The ProFlo™ series pumps are designed for intermittent duty. Make sure that “OFF” periods are sufficient. Consult the factory for particular data and design criteria.
• Be sure power supply used is adequate for the application.
• Pump and motor specifictions are based on an alternator charged battery (13.6 VDC)
• Use sufficient battery supply power. UTV and lawn tractor batteries may affect pump performance due to low voltage and amp ratings
• Rapid On/Off 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:

• Contact factory for RMA number.
• Flush chemical residue from the pump (best done in the field).
• Tag pump with type of chemicals having been sprayed.
• Include a complete description of the operation problem, such as how the 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.
