Installation Instructions

1. Remove all components from packaging.
2. Select desired area to mount the control box.
   Note: We recommend mounting the control box at a height of 6 feet or less. The chemical suction line must reach the bottom of the chemical container. The bottom of the chemical container should not be positioned higher than the bottom of the control box.
3. Attach the control box mounting feet to the back of the control box, using the four screws provided in the parts package.
4. Mount the control box to the wall using four of the screws and plastic anchors provided in the parts package. Note: To drill holes for the plastic anchors, use a 5/16 inch drill bit.
5. Mount the hose hanger in a convenient location using the remaining two screws and anchors provided in the parts package.
6. Attach the discharge hose assembly to the discharge hose barb and secure it with the larger hose clamp provided in the parts package.
7. Connect the air inlet hose barb provided in the parts package to the air inlet valve located on the side of the control box. Then attach a 3/8 inch I.D. air line from your air compressor to the air inlet hose barb, and secure it with the smaller hose clamp provided in the parts package.
8. Connect a water line to the unit. The control box has a 1/2 inch FPT water inlet fitting. A garden hose adapter fitting assembly is included in the parts package.
   Note: A back-flow preventer must be installed in the water line – check local plumbing codes to ensure proper installation.
9. Open the cover of the control box. Insert the proper metering tip and connect the chemical intake line to the injector inlet barb.
   Note: Use the included metering tip color chart to determine the appropriate metering tip based on the product and dilution rate you will be using.
10. Place the other end of the chemical intake line into a chemical container.
    Note: The chemical suction line must reach the bottom of the chemical container. A strainer must be used on the chemical intake line.

METERING TIP COLOR CHART

*Injection rates will vary based on chemical viscosity, air pressure, and many other factors. We recommend testing unit output to verify injection rate prior to use.

Operation Instructions

1. Follow all instructions from chemical manufacturer.
2. With the discharge valve in the closed position, open the air inlet valve.
3. Slowly open the discharge ball valve to begin foaming. The discharge ball valve should be completely open while foaming.
4. While the unit is running and discharging product, adjust the needle valve, located inside the control box, as needed to regulate the wetness or dryness of the foam following the steps below:
   • Close needle valve completely in clockwise direction.
   • Open needle valve in counter-clockwise direction 3 complete turns.
   • Continue to open needle valve in ¼ turn increments, allowing 30 seconds between adjustments, until desired consistency of foam is achieved.

After Use Instructions
We recommend flushing the discharge hose and depressurizing the unit after each use.

1. Place the chemical suction line into a container of water.
2. With the unit running, open the discharge valve, and allow the unit to be flushed with fresh water thoroughly until all chemical has been discharged from system.
3. Shut off the air supply to the unit by closing the air inlet valve.
4. Shut off the water supply to the unit.
5. Open the discharge valve to relieve any pressure remaining in the unit.
6. Close the discharge valve after all pressure has been relieved from the unit. Store the unit with the discharge valve in the closed position.

Maintenance Instructions

To keep the unit operating properly, periodically perform the following maintenance procedures:
Note: Before performing any maintenance, ensure that the unit has been disconnected from the air and water supply and depressurized according to the After Use Instructions.

• Inspect the pump for wear and leaks.
• Inspect all hoses for leaks or excessive wear. Make sure all hose clamps are in good condition and properly secured.
• Replace the filter located within the air regulator as needed. Clean by unthreading the air regulator bowl from the air regulator.
• Check the chemical metering tip, suction line and strainer for debris and clean as needed.
• Drain your air compressor tank on a regular basis to help extend pump life. An air source with a high moisture content will accelerate pump wear. Note: If your air source has a high moisture content, you may wish to install a water separator before the unit.

Troubleshooting Instructions

• Check to ensure that the discharge hose is uncoiled properly, and that there are no kinks that could obstruct fluid flow.
• Check the air regulator bowl and air filter for debris such as water, oil, or rust particles. Clean by unthreading the air regulator bowl from the air regulator.
• If the needle valve is open too far, the pump may cycle improperly due to lack of air pressure. If this occurs, close and readjust the needle valve as described in the Operation Instructions.
• Make sure proper foaming chemical and concentration are being used.
• If air passes through the pump without cycling, the pump needs to be replaced.
• If solution backs up into the air regulator bowl, the check valve needs to be replaced.
• If foam comes out wet, no matter where the needle valve is positioned, the check valve may need to be replaced.
• Check for proper air pressure on the air gauge. The air regulator is factory set at 50 psi (3.4 bar). Operating range is 40 to 80 psi (2.8 to 5.5 bar) with 5 to 10 CFM (141.6 to 283.2 l/min).
• If the unit operates at a reduced air pressure:
  • Check the air compressor supplying the unit. If the pressure is less than 40 psi (2.8 bar), turn the unit off until the compressor can catch up.
  • If the air supply is 50 psi (3.4 bar) or above, check the air gauge, which should read near 50 psi (3.4 bar). If the air gauge reads more or less than 50 psi (3.4 bar), adjust the pressure by turning the knob on the top of the air regulator.
• Check the chemical metering tip, suction line and strainer for debris or damage. Clean or replace as needed. To prevent damage to the unit, the strainer must always be used.
• Check for proper water pressure on the water pressure gauge. To check the pressure:
  • With the unit running, open the discharge valve and allow the unit to run for about 1 minute.
  • Close the discharge valve.
  • Check the water pressure gauge. The pressure should read 30 psi (2.1 bar).
  • If necessary, adjust the water regulator using the flathead screw on the regulator body. The water pressure should be set at 30 psi (2.1 bar). Setting the pressure higher or lower may damage the unit or cause it to malfunction.
