Safety

PEOPLE OR OBJECTS CAN BE HURT OR DAMAGED IF THIS UNIT IS NOT USED CORRECTLY!
Failure to read all the instructions before operating the unit may result in personal injury or death from the improper use of the chemical solution. Anyone handling, operating or using the unit must read and understand the instructions in the manual. The buyer assumes all responsibility for the safety and proper use of the instructions.

Using or servicing the unit without appropriate personal protective equipment (PPE) may result in serious injuries such as burns, rashes, eye, throat or lung damage and death. Always wear PPE as indicated in the Safety Data Sheet (SDS) when using or servicing the unit. Protect eyes, skin, and lungs against drifting spray.

Chemical solutions may pose a health risk and death if they contact the skin or eyes, and are inhaled or swallowed. Always read and follow all chemical safety precautions and handling instructions provided by the chemical manufacturer and the SDS associated with the chemical solution before using the unit.

Pressure within the equipment may cause an unexpected release of the chemical solution and cause serious injury such as burns, rashes, eye damage, throat or lung damage and death. Always depressurize and clean the unit after each use. Release any remaining air pressure by opening the discharge ball valve. Never leave the unit unattended while pressurized. Using the unit with fluid temperatures above 100°F (37.8°C) may result in scalding, burns, serious injury or death.

DO NOT use a solution with a temperature above 100°F (37.8°C). Operating the unit when damaged or leaking may result in exposure to chemical solutions, serious injury or death. Never use the unit if it is damaged or leaking. Never point the discharge wand at yourself, another person, or any object you do not want covered in chemicals.

Using incoming air pressure exceeding 100 psi (6.9 bar) may result in pressure buildup, explosion, serious injury or death. DO NOT exceed 100 psi (6.9 bar) incoming air pressure when operating the unit.
Use of hydrocarbons and flammable products may result in explosions, fire and serious injury or death. Never use hydrocarbons or flammable products with the unit. Mixing an alkaline with an acid may result in a chemical reaction. Overheating of the mixture may cause it to splatter caustic compounds or release hazardous fumes, gas and vapours. Always flush the unit with fresh water thoroughly when switching from an alkaline to an acid or an acid to an alkaline.

NOTICE
Servicing or modifying this unit with parts not listed in this manual may cause the unit to operate improperly. Do not use unauthorized parts when servicing the unit. Use of an air lubricator before the unit may result in diminished performance and damage to the unit. Do not use an air lubricator before the unit. Moisture in the airlines will damage the pump and diminish the pump’s life. The air must be filtered, clean, dry and free of moisture. If needed, install an air dryer before the unit.

Operating Instructions

1. Verify drain plug is securely closed.

2. Following all instructions from the chemical manufacturer, fill the solution tank with a pre-mixed solution.

3. Verify that the suction line valve at the base of the suction line is open, allowing fluid into the suction line.

4. With the discharge ball valve in the closed position, plug an airline into the air fitting. Slowly open the discharge ball valve to begin foaming.

5. The discharge ball valve should be completely open while foaming.

6. While the unit is running and discharging product, adjust the needle valve as needed to regulate the wetness or dryness of the foam by following the steps below:

   • Close the eedle valve completely in a clockwise direction.
   • Open the needle valve in a counter-clockwise direction with 3 complete turns.
   • Continue to open the needle valve in ¼ turn increments, allowing 30 seconds between adjustments, until the desired consistency of foam is achieved.

7. Close the discharge ball valve to stop foaming.

8. After Use Instructions
   NOTE: For proper handling and disposal procedures refer to chemical SDS.

9. The solution should be removed from the unit after each use. This can be done in two ways:

   • Unthread the drain plug from the front of the tank and drain the solution into the approved location.
   • Place the discharge wand into an approved container to transfer the remaining solution. Turn the needle valve to the wet setting and activate the unit until all solutions have been flushed from the system.

10. After the solution has been removed, disconnect the air line from the air fitting.

11. Open the discharge ball valve to relieve the remaining pressure.

12. Close the ball valve after all pressure has been relieved. Store unit with discharge ball valve closed.

13. Before using the unit with another chemistry, thoroughly flush with water.

Troubleshooting Your Unit

If your unit is not operating properly, try using these troubleshooting tips:

Air regulator bowl or air filter has debris such as water, oil, or rust particles| •   Clean by unthreading the air regulator bowl from the air regulator.
Pump is cycling improperly| •   The needle valve is open too far. Close and readjust the needle valve as described in the operation section.

•   Ensure proper foaming chemical and concentration are being used.

Air passes through the pump without cycling| •   The pump needs to be replaced.
The solution backs up into the air regulator bowl| •   The check valve needs to be replaced.
Foam comes out wet, no matter where the needle valve is positioned| •   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 283.3 l/min).

•   The check valve may need to be replaced.

•   Verify correct chemical concentration is being used.

The unit operates at a reduced pressure| •   Check 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 the air compressor supplying the unit. If the pressure is less than 40 psi (2.8 bar), turn off the unit 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 if the stainless steel mixing mesh is plugged. Remove and clean it by following the instructions below:

1.    Verify the unit is not plugged into an air supply and then relieve all stored pressure in the unit by turning the ball valve to the open position.

2.    Remove discharge hose from hose barb on back of the unit.

3.    Open back plate assembly and hold stainless tee with wrench to remove hose barb from tee fitting.

4.    Remove the screen and the mixing mesh from inside the tee fitting.

5.    Clean any particles from the mixing mesh and the screen. If the mixing mesh has a lot of foreign particles in it, make sure the suction strainer is still in place.

6.    Replace the mixing mesh and screen into the back of the tee. Screw the stainless hose barb back into the tee.

NOTE: It is recommended to use a pipe thread sealant when reinstalling the stainless hose barb back into the tee fitting.
