User Manual: 50 Gallon Smart Foam Unit | English
READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT
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 ¼ 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.
