• Never point the discharge wand at anyone.
• Incoming air pressure cannot exceed 100 psi (7 bar).
• After each use, relieve all remaining pressure in the system by unplugging the air line from the unit and opening the discharge ball valve to prevent accidental discharge.
• After relieving the pressure from the unit, store the unit with the ball valve in the closed position.

Operation Instructions

1. Follow all instructions from chemical manufacturer. Fill the tank with water and the advised percentage of chemical concentrate.
2. With ball valve (HV60) in the closed position, plug an air line into the air fitting (AP25).
3. Slowly open the ball valve (HV60) completely.
4. Adjust the needle valve (NV14Y) to desired wetness or dryness of foam following the steps below:
5. Close needle valve completely in clockwise direction.
6. Open needle valve in counter-clockwise direction 3 complete turns.
7. Continue to open valve in ¼ turn increments allowing 30 seconds between adjustments until proper consistency of foam is achieved.

After Use Instructions

1. Flush the unit with fresh water for 5 minutes.
2. Disconnect the air line from the air fitting (AP25) and relieve any remaining pressure in the system by opening the discharge ball valve (HV60).
3. Close the ball valve (HV60) after all pressure has been relieved from the system.

Maintenance Instructions
To keep your portable tank foamer operating properly, periodically perform the following maintenance procedures:

• Check the air pump (P56/P56K/P56V) for wear and leaks.
• Inspect hoses for leaks or excessive wear. Make sure all hose clamps are in good condition and properly secured.
• Replace filter (AFR25) in regulator (R25) as needed.
• Check the suction tube and screen for debris and clean as needed.
• Drain compressor tank on a regular basis to ensure proper operation of pump.

Troubleshooting Instructions

• Check to ensure the discharge hose is uncoiled properly, and that there are no kinks that could obstruct fluid flow.
• Check air regulator bowl (ABR25) for debris such as water, oil, or rust particles. Clean by unthreading the air regulator bowl from the air regulator (R25).
• If needle valve (NV14Y) valve is open too far, the pump (P56/P56K/P56V) will cycle improperly due to lack of air pressure. If this occurs, reset needle valve as described in Operation Instruction #4.
• Make sure proper foaming chemical and concentration is being used.
• If air passes through the pump (P56/P56K/P56V) without cycling, the pump needs to be replaced.
• If foam solution backs up into 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 air gauge (AG100). 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 (141.64 to 283.30 l/min)
• If the unit foams at a reduced pressure:
  • Check the air compressor supplying the unit. If the pressure is less than 40 psi, turn the foam unit off until the compressor can catch up.
  • If the air supply is 50 psi (4.14 bar) or above, check the AG100, which should read near 50 psi (4.14 bar). If the AG100 is more or less than 50 psi (4.14 bar), adjust the pressure by turning the knob on the top of the air regulator (R25).
  • If both of the above are okay, the stainless steel mixing mesh (SS-MESH) could be plugged. Remove and clean it by following the instructions below:
  1. Be sure the foam unit is not plugged into an air supply and be sure to relieve all stored pressure in the unit by having the ball valve (HV60) in the open position.
  2. Remove the stainless adaptor (HBSS1234) from the tee fitting (SST12HB38).
  3. Remove the screen and the mixing mesh from inside the tee fitting (SST12HB38).
  4. Clean any particles from the mixing mesh and the screen.
  5. Replace the mixing mesh and then the screen into the back of the tee and screw the stainless adaptor back into the tee. It is recommended to use a pipe thread sealant when reinstalling the stainless adaptor back into the tee fitting (SST12HB38). If the mixing mesh has a lot of foreign particles in it, make sure the strainer (STR38-IL) is still in place.
• Check for plugged strainer (STR38-IL). Replace strainer if necessary. Strainer must be used.
