Operation Instructions:

1. Verify that the drain plug (DP-A) is securely closed.

2. Follow all instructions from the chemical manufacturer. Fill the tank with water and the advised percentage of chemical concentrate.

3. Verify that the valve (PVCV34FM) at the base of the suction line is open, to allow fluid into the suction line.

4. Verify that the air trigger port is clean and free of blockages or debris, and the discharge hose is not kinked or obstructed.

5. With the wand pointed in a safe direction, connect an air line to the air inlet fitting (AP25).
   Note: When you connect the air line, listen for any sound from the unit. If you hear the pump activate and begin to cycle, disconnect the air line 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”).

6. Place thumb over the air trigger to activate the unit and begin foaming.

7. 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 clockwise direction.
   b. Open needle valve in counter-clockwise direction 2 complete turns.
   c. Continue to open needle valve in % turn increments, allowing 30 seconds between adjustments, until desired consistency of foam is achieved.

8. 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.

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, and/or close the valve (PVCV34FM) at the base of the suction line to shut off the flow of liquid from the tank. Reopen the valve after maintenance is complete.

• 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.

After Use Instructions:

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

• If the pump is cycling but will not pull product, and the suction line is clear, make sure the valve (PVCV34FM) at the base of the suction line is open.

• Check the air regulator bowl (ABR25) and air filter (AFR25) for debris such as water, oil, or rust 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 chemical and concentration are being used.

• If air passes through the pump (P56/P56K/P56V) without cycling, the pump needs to be replaced.

• If 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).
  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 a 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).

• 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 air line, the valve block (SM- PV) may need to be replaced.
  b. If the unit does not activate when you connect the air line, 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 guage (AG100).
  2. If the problem persists, the valve block (SM-PV) may need to be replaced.
