OVERVIEW
The FPS-MM Asphalt Release Sprayer is a chemical spray applicator for diluting and projecting asphalt release chemicals on to truck beds or tools to prevent asphalt
from sticking. This system features a lockable, stainless steel enclosure and uses a cost-effective 1/4" Flojet air-operated, double-diaphragm pump to draw chemical
concentrate and water from separate static tanks and blend them to create virtually any dilution ratio (or draw neat chemical). The solution is then projected through
the hose, trigger gun, wand and fan nozzle.

SAFETY & OPERATIONAL PRECAUTIONS
For proper performance do NOT modify, substitute nozzle, hose diameter or length
Manufacturer assumes no liability for the use or misuse of this unit.
Wear protective clothing, gloves and eye-wear when working with chemicals.
Always direct the discharge away from people and electrical devices.
Follow the chemical manufacturer’s safe handling instructions.
DO NOT use d-Limonene or other chemicals that are not compatible with the Santoprene diaphragms.
Viton upgrade is available.
TO INSTALL (REFER TO DIAGRAM ON NEXT PAGE)
1. Mount the unit above chemical and / or water containers.
2. Securely attach the suction tubes to the check valves as shown in the drawing.
3. Place one tube/strainer in the chemical concentrate(s) and the other in a static container of water. (DO NOT use
pressurized water!)
4. Attach a compressed airline to the inlet ball valve. DO NOT TURN ON
How to Set Your Dilution Ratio:
The adjustment knobs allow you to achieve wide range of dilution ratios.
Turn adjustment knobs counterclockwise to increase flow or clockwise to decrease flow.
For a starting place turn the water knob completely clockwise (closed) then turn 2 turns counterclockwise (open).
Then turn the chemical knob completely clockwise (closed) then counterclockwise (open) in 1/4 to 1/2 turn
increments till required dilution ratios are achieved.
If ratios can't be achieved with the chemical knob all the way counterclockwise start turning water knob clockwise
to shift more draw to the chemical side.
For weaker solutions than the knobs can achieve use a metering tip to further reduce the chemical flow (some
units do not include metering tips standard).
TO OPERATE
Always make sure the discharge is pointed in a safe direction before turning inlet valve on. Trigger can be
released at any time during operation but should not be left unattended for long periods of time without closing
inlet ball valve.
1. Open the inlet ball valve point the wand in a safe direction and pull the trigger on the gun.
2. Final chemical dilution adjustments will now have to be made. Make adjustments to the knobs based on results.
3. If the solution seems to be too weak slowly turn the chemical knob counterclockwise.
4. Continue opening till the solution is strong enough for the application.
5. Once dilution ratio is set, release the trigger gun or begin application.

Troubleshooting Guide
Problem Possible Cause / Solution
Startup Maintenance
A) Air pump will not run or pump solution.
B) Unit will not draw chemical or water.
C) Using too much chemical
D) Asphalt sticking in truck bed.
E) Pump runs too fast with no output.

Possible Cause / Solution
Startup Maintenance
1. Air adjustment too low
Open air ball valve fully. Adjust air regulator slowly
clockwise. Optimum air pressure is at least 60 PSI 90
PSI maximum.
2. Water or chemical tube not immersed in container or
container empty
Immerse tube or replenish.
3. Dilution too strong
Turn chemical knob slightly clockwise or water knob
counterclockwise.
4. Dilution too weak
Turn chemical knob slightly counterclockwise or water
knob clockwise.
5. Discharge hose kinked
Straighten the hose.
6. Air regulator clogged or failed
Clean or replace.
7. Water or chemical check valve stuck or clogged
Clean or replace.
8. Chemical or water strainer clogged up
Clean or replace.
9. Vacuum leak in metering manifold or suction side of the
pump
Check and tighten the hose clamps connection(s). After
unit has been in service the plastic fittings could have
"relaxed" and may need tightened too.
NOTE: This is the most common problem when the
unit will not draw water or chemical!
10. Chemical or water tube stretched out where tube slides
over check valves or pin hole/cut in tube sucking air.
Cut off end of tube or replace tube, add a hose clamp,
do not over tighten.
11. Problem with air pump
Refer to air pump instruction manual.
Pump suction and discharge manifolds are loose,
tighten bolts.
12. Use of an oiler in the airline will cause pump to stall
Use only clean, dry air.
PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush the chemical out
of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical strainer and replace if missing.
