CONTENTS- NOT TO SCALE

PRESSURE GAUGE & BALL VALVE ASSEMBLY

Install pressure gauge (C-1) and ball valve (C-2) to output manifold as shown. Insert lead wire assembly into plug at rear of pump. Join red wire of the lead wire to a +12V source on the garden tractor. The black wire should be grounded or connected to the negative battery post.

WAND TUBING TO MANIFOLD

Install wand tubing (C-7) to manifold as shown using supplied hose clamp (C-3 ).

INSTALL DRAIN CAP

Install cap lanyard around drain plug. Screw drain cap (C-5) on drain plug.

VALVE OPERATION

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 spray wand.
The pump has a pressure switch which will shut the pump off when it reaches 60 PSI.
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 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.

TROUBLESHOOTING

Fuse or breaker
Pressure switch operation
Rectifer or motor for open or grounded circuit
Locked drive assembly
Correct voltage at switch
Pump will not prime

(No discharge with motor running)

| Debris in strainer
Restriction (kinks) in inlet / outlet tubes
Debris / swelling in inlet / outlet valves
Pump will not shut-off (output line closed and no leaks)| 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| Loose screws at switch or pump head
Switch diaphragm ruptured or pinched
Punctured diaphragm if fluid is present
Pump makes noise, but no output| Prime with garden hose by removing intake hose and flood with water while pump is running until water starts flowing (this may take up to 15 minutes to create suction).

SPRAY & PUMP FAQ

1. Why does the pump not run all the time?
   This is an on-demand pump and only runs with flow; spray wand, by-pass, spray tips
   or leak in system.

2. 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 ajusted for a small or fine spray pattern. To overcome, slightly open the by-pass valve or open nozzle slightly.

3. How do I adjust the pressure?
   Pressure should be adjusted by regulating the by-pass valve (slightly opening or closing).

4. 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.

5. 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.

6. 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

7. 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.

8. Is there a fuse for the sprayer?
   Yes, either an in-line fuse, a fuse located in the car adapter housing or both.

9. What size fuse should I use as a replacement?
   10 amp

10. What is the range of the spray wand?
    35 feet max

11. How should I clean the tank after use?

    • Rinse tank thoroughly with water only, empty, refill with water.
    • Empty sprayer by spraying no less than 1 minute to rinse out line. The remaining water can be drained per the drain plug.
    • Store sprayer tank upside down, in a warm dry location.

12. 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.

13. Each time I turn on the pump my fuse blows.

    • Excessive voltage
    • Improper adjustment of the pressure switch
    • Damaged wiring harness.

14. Pump continues to run and surge when not spraying.
    Ensure your system has no leaks. Check by-pass valve to ensure it’s not letting too much fluid to bypass. If too much fluid is bypassed, the system is unable to build enough pressure to shut-off.
