SPRAYER COMPONENTS AND USE INFORMATION
• Mix Setting Valve (1)
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.
• Wand/Boom Selector Valve (2)
The wand/boom selector valve allows the user to select the
flow to either be diverted to the wand assembly or the boom.
• Bypass/Pressure Valve (3)
The bypass/pressure valve allows the user to adjust the wand's
pressure. During low flow applications it allows 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
counter clockwise 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.
• Chemical Concentrate Tank (4)
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.
• Chemical Tank Quick Release Coupling (5)
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 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.
NOTE:
- Always follow chemical manufacturer's instructions for proper use, storage and disposal.
- Always follow state/local codes for proper handling, storage and disposal of chemical.

How to Operate:

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 system on by pressing wiring harness in-line switch to "on" (not shown).
6. Prime: using 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 disconnect the concentrate tank's
quick release. This allows chemical 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 mix 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.
