SPRAYER HARDWARE

SPRAYER COMPONENTS

NOTE: not all components shown may be needed on your model.

ASSEMBLE PUMP TO TANK

Using H-1 screws, fasten pump (C-2) to faceplate with loop clamp (H-6) inserted between pump and front left screw. NOTE: Do not over-tighten screws.

INSTALL EXTERNAL BYPASS AND FLOW DIRECTOR VALVE
Install external bypass (C-3) and flow director valve (C-4) into pump quick release ports; engage quick release locks. Note: to ensure a good seal, a tight fit is used; significant hand force may be necessary to install bypass fittings.

INSTALL WAND CLIPS
Install wand clip (H-4) and wand clip from nylon strap (as shown above) with screws (H-2). Note: The wand clip shown to the right can be found hanging from the nylon strap.

ATTACH HOSE TO DIVERTING VALVE
Guide wand hose (C-1) through loop clamp (H-6) and attach hose (C-1) to diverting valve (C-4) with hose clamp (H-3). Tighten clamp (H-3).

WAND ASSEMBL Y
Make sure the o-ring is installed on the end of the wand. Insert the wand into shut-off valve. Turn and tighten the retaining nut clock-wise onto the shut- off valve.

ATTACH CHEMICAL CONCENTRATE TANK
Before chemical tank installation, attach supplied rachet straps to strap slots on tank. Securely fasten assembly to ATV. NOTE: not all models included ratchet straps.
Attach the mix valve’s suction tubing (1) to the chemical concentrate tank’s quick release port (2). Secure chemical concentrate tank with nylon webbing (3).

INSTALL DRAIN CAP

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

SPRAYER COMPONENTS

1. MIX SETTING VALVE
   The mix setting valve allows the user to set the desired chemical mix ratio. It is calibrated to a specific gravity of water. See setting chart for each settings mix value in oz./gal. Due to chemical viscosity, actual mix ratios may vary. Refer to chemical’s recommended mix ratios when choosing what setting to use.
   Note:

   • Use water based chemicals only.
   • When not spraying set mix ratio to zero.

2. WAND / BOOM SELECTOR VALVE
   The wand/boom selector valve allows the user to select the flow to either be diverted to the wand assembly or the boom.

3. BYPASS / PRESSURE VALVE
   The bypass/pressure valve allows the user to adjust the wand’s pressure. During low flow applications, it allows the flow to be diverted to eliminate pump cycling.
   How to use: Start with the valve set to “Bypass off”. When the pump begins to cycle; between on and off, turn the valve slowly counterclockwise until the cycling stops. The valve setting should fall in the “optimal” flow region.
   Note:

   • If the bypass is used beyond the “optimal flow” region the pump may not shut off as the bypass doesn’t allow it to build enough pressure to turn the pump off.
   • If too much air is introduced into the system from changing chemicals or running the water or chemical tanks dry it may be necessary to switch the bypass valve to “Bypass off/Prime” in order to prime the unit.

4. CHEMICAL CONCENTRATE TANK
   The chemical concentrate tank is where the chemical concentrate is held. To install the tank, insert the tank onto the faceplate’s alignment feet and secure with the nylon webbing and snap latch.

5. CHEMICAL TANK QUICK-RELEASE COUPLING
   The chemical tank quick-release coupling allows the user to quickly and cleanly change out chemical tanks. When disengaged the tank’s quick-release automatically closes to stop spillage. To use, align the male locking pins with the female nut’s slots. Press the female nut over the male nut and turn clockwise to lock in place. To disengage the quick-release coupling, slightly push the female nut in, turn counterclockwise, and remove.

OPERATING INSTRUCTIONS

1. Fill both water and chemical tanks.
2. Set Mix Ratio Valve to “0” (1) by turning the adjustment wheel.
3. Set Wand/Boom selector valve to “Wand” (2).
4. Set Bypass to “Bypass Off/Prime” (3) by turning the selector knob.
5. Turn the system on by pressing the wiring harness in-line switch to “on” (not shown).
6. Prime: Use the wand spray until all air has been purged from the system. If the bypass was set to “off” the pump will begin to cycle on and off.
7. Adjust bypass until the pump stops cycling. Do not bypass more than needed as this will cause the pump to continuously run.
8. Set the desired mix ratio setting and begin spraying.
9. Cleaning between chemical types: While spraying on mix setting 7 disconnects the concentrate tank’s quick release. This allows chemicals in the line to quickly be flushed. If necessary, flush with water by submerging the chemical line into the water source. Once adequately flushed the new concentrate tank may be installed. With the mixing valve set to 7 and the bypass set to “Bypass off/Prime” prime the system. Once primed, re-adjust the bypass valve and you’re ready to spray.

SETTING GUIDE

4| 4 oz/gal
5| 5 oz/gal
6| 10 oz/gal

Chemical mix ratios can easily be adjusted in between or lower than the listed 0-7 settings by pre-diluting your concentrate.
For example, if you wish to spray at .5 oz/gal, simply mix your chemical 50:50 with clean water before placing it in the concentrate tank.
Divide the desired rate by the closest higher rate
(oz. /gal) value from the above guide to determine the % of chemicals in the concentrate tank.

ALWAYS FOLLOW THE CHEMICAL MANUFACTURER’S INSTRUCTIONS FOR PROPER USE, STORAGE AND DISPOSAL.
ALWAYS FOLLOW STATE/LOCAL CODES FOR PROPER HANDLING, STORAGE AND DISPOSAL OF CHEMICAL.

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
Bypass is not in “off” position
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 output spits and sputters| All hose clamps are adequately tight
No holes in tubing
There is adequate liquid in both the water and chemical tank
Adjust external bypass to optimize spray pattern
The pump makes noise, but no output| Prime with a 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 a demand pump and only runs with the flow; a specific pressure must be reached before the pump turns off.

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 adjusted for a small or fine spray pattern. To overcome, slightly open the by-pass valve, or adjust the nozzle to allow more flow.

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

4. My pump quit and will not restart – what should I check?
   Check all electrical connections. Ensure the switch is in the on position. Check in-line
   fuse and/or fuse in-car adapter end. Ensure correct voltage +/- 10%. 12-14 volt

5. 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. Check for a crimped hosing.

6. Is there a fuse for the sprayer?
   Yes, in line to the 12V wiring harness.

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

8. How should I clean the tank after use?

   • Rinse the tank thoroughly with water only, empty, and refill with water.

   • Open shut-off and allow water to run through the discharge assembly. Empty
     sprayer.

   • If the unit is to be stored below freezing the best way to winterize is to run RV
     antifreeze through both lines before storage, then purge with water in the spring.

9. Is there an adjustment screw on the pump to adjust the pressure?
   Yes, please refer to the operation instructions, “Adjusting the Pressure Switch”.

10. How do I remove/replace the fuse?
    Open fuse housing, remove fuse if blown, and replace with equivalently rated fuse.

11. 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.

12. Each time I turn on the pump my fuse blow s.

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

13. The pump continues to run and surge when not spraying.
    Ensure the by-pass is completely closed and your system has no leaks.
