READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT

WARNING

Read this manual completely and understand the machine before operating or servicing it.

• Read all instructions before installing or operating the unit.
• Always wear appropriate personal protective equipment (PPE) when operating or servicing the unit.
• Always follow all chemical safety precautions and handling instructions provided by the chemical manufacturer and Safety Data Sheet (SDS).
• If this unit is modified or serviced with parts not listed in this manual, the unit may not operate correctly.
• Never point the discharge wand at yourself, another person, or any object you do not want to be covered in chemicals.
• Always keep the air trigger port clean and free of blockages or debris. If the port becomes dirty or blocked, disconnect the compressed air source from the unit immediately and clean out the port before proceeding.
• Always keep the discharge hose free of kinks or obstructions.
• Always rinse and drain the unit after use (as described in the After Use Instructions). Always store the unit disconnected from the compressed air source.
• Do not exceed an incoming air pressure of 100 psi (7 bar).
• Do not exceed a fluid temperature of 100˚F (37˚C).
• Always flush the unit with fresh water for 5 minutes when switching from an alkaline to an acid or an acid to alkaline.
• Only use clean and dry air. Air must be filtered and free of moisture or pump life will be diminished. If needed, install a water separator (WS-20CFM) before the unit.
• Do not use an air lubricator before the unit.

SPECIFICATIONS

*Dilution rates and flow rates given are based on chemicals with a viscosity of water and factory air pressure settings.

Operation Instructions:

1. Follow all instructions from the chemical manufacturer.
   Fill the tank with water and the advised percentage of chemical concentrate.
2. Verify that the air trigger port is clean and free of blockages or debris, and the discharge hose is not kinked or obstructed.
3. With the wand pointed in a safe direction, connect an air line to the air inlet fitting (AP25).
   Note: When you connect the airline, listen for any sound from the unit. If you hear the pump activate and begin to cycle, disconnect the airline immediately. This indicates that there is a blockage or other problem somewhere in the system, which could cause the unit to activate spontaneously. The problem must be addressed before proceeding (see “Troubleshooting Instructions”).
4. Place thumb over the air trigger to activate the unit and begin foaming.
5. While the unit is running and discharging product, adjust the needle valve (NV14Y) as needed to regulate the wetness or dryness of the foam following the steps below:
   a. Close needle valve completely in a clockwise direction.
   b. Open needle valve in counter-clockwise direction 2 complete turns.
   c. Continue to open needle valve in ¼ turn increments, allowing 30 seconds between adjustments, until desired consistency of foam is achieved.
6. Release the air trigger to stop foaming.
   Note: When you release the air trigger, the unit will shut off and depressurize. Foam that is already in the discharge hose may seep out, but no more foam will be created until you cover the air trigger again.

After Use Instructions:

1. Rinse the unit tank thoroughly with fresh water. Then fill the tank with fresh water.
2. Activate the unit and allow it to run for 2-4 minutes, or until all chemical has been flushed from the system.
3. Disconnect the air line from the air fitting (AP25).
4. Allow any liquid remaining in the discharge hose to drain out through the discharge wand before storing the unit.

Maintenance Instructions:

To keep your unit operating properly, periodically perform the following maintenance procedures:
Note: Before performing any maintenance, ensure that the unit has been disconnected from the air supply according to the “After Use Instructions.” Also, ensure that the unit tank is empty.

• Inspect the air pump (P56/P56K/P56V) for wear and leaks.
• Inspect all hoses for leaks or excessive wear. Make sure all hose clamps are in good condition and properly secured.
• Check the air trigger port on the handle for debris and clean as needed. When cleaning, be careful not to push debris into the port, as it may become lodged inside and create a blockage.
• Clean and replace the filter (AFR25) located within the air regulator (R25) as needed. Access the filter by unthreading the air regulator bowl (ABR25) from the air regulator (R25).
• Check the suction line and strainer (STR38-IL) for debris or blockages, 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 (WS-20CFM) 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 suction line and strainer for debris or damage.
  Clean or replace as needed. To prevent damage to the unit, the strainer (STR38-IL) must always be used.
• Check the air regulator bowl (ABR25) and air filter (AFR25) for debris such as water, oil, or dust particles. Clean by unthreading the air regulator bowl (ABR25) from the air
  regulator (R25).
• If the needle valve (NV14Y) is open too far, the pump (P56/P56K/P56V) may cycle improperly due to lack of air pressure. If this occurs, close and readjust the needle valve (NV14Y) as described in the Operation Instructions.
• Make sure proper foaming chemicals and concentrations are being used.
• If air passes through the pump (P56/P56K/P56V) without cycling, the pump needs to be replaced.
• If the solution backs up into the air regulator bowl (ABR25), the check valve (CV38) needs to be replaced.
• If foam comes out wet, no matter where the needle valve (NV14Y) is positioned, the check valve (CV38) may need to be replaced.
• Check for proper air pressure on the air gauge (AG100).
  The air regulator (R25) is factory set at 50 psi (3.4 bar).
  The operating range is 40 to 80 psi (3 to 5 bar) with 5 to 10 CFM (141.6 to 283.3 l/min).
• If the unit operates at reduced pressure:

1. Check the air compressor supplying the unit. If the pressure is less than 40 psi, turn the unit off until the compressor can catch up.
2. If the air supply is 50 psi (3.4 bar) or above, check the air gauge (AG100), 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 (R25).
3. If the problem persists, the stainless steel mixing mesh (SS-MESH) inside the tee fitting (SST12HB38) could be plugged. Remove and clean the mesh following the instructions below:
   a. Ensure that the unit has been flushed and disconnected from the air supply according to the “After Use Instructions.” Also ensure that the unit tank is empty, and/or that the valve (PVCV34FM) at the base of the suction line is closed.
   b. Remove the stainless hose barb (HBSS1258) from the tee fitting (SST12HB38).
   c. The stainless steel mixing mesh (SS-MESH) is located inside the tee fitting (SST12HB38).
   Remove the old mesh and the screen that holds it in place. If the mesh and screen are in good condition, they can be cleaned and re-used. If not, they should be replaced with new parts.
   d. Insert the new mesh (SS-MESH).
   e. Insert the new screen (SSST). Make sure it is seated securely, but not bent or deformed.
   f. Reconnect the hose barb (HBSS1258) to the tee fitting (SST12HB38). Attach the 5/8 inch hose to the hose barb (HBSS1258) and secure it with the screw band clamp (SSC58).
   g. If you found a lot of particles or blockages inside the mesh, check the suction line strainer (STR38-IL) to make sure it is in place and operating correctly.

• If the unit activates when the air trigger port is not covered:
  1. Verify that the air trigger port is clean and free of blockages or debris, and the discharge hose is not kinked or obstructed.
  2. If the problem persists, try bypassing the air trigger.
  To do this, disconnect the 1/4 inch hose from the wand. Point the wand in a safe direction and connect an air line to the unit. Then, use your thumb or finger to seal the open port of the 1/4 inch hose at the wand.
  a. If the unit activates when you connect the airline, the valve block (SM-PV) may need to be replaced.
  b. If the unit does not activate when you connect the airline, the hose or wand assembly may need to be replaced.
• If the unit does not activate when the air trigger port is covered:
  1. Confirm the incoming air supply is consistently 50 psi (3.4 bar) on the air gauge (AG100).
  2. If the problem persists, the valve block (SM-PV) may need to be replaced.
