READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT
Operation Instructions:
1. Fill the tank with water and the advised percentage of
chemical agent.
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:
a. Close needle valve completely in clockwise direction.
b. Open needle valve in counter-clockwise direction 2
complete turns.
c. Continue to open valve in ¼ turn increments allowing
30 seconds between adjustments until proper
consistency of foam is achieved.
After Use Instructions:
1. Open drain plug (DP-A) and empty tank.
2. Fill tank with clean water.
3. Flush the unit with fresh water for 5 minutes.
4. Disconnect the air line from the air fitting (AP25) and
relieve any remaining pressure in the system by having
the ball valve (HV60) in open position.
5. Close the ball valve (HV60) after all pressure has been
relieved from the system.
6. Drain the tank.
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
o
pressure is less than 40 psi (3 bar), turn the foam
unit off until the compressor can catch up.
If the air supply is 50 psi (3.4 bar) or above, check
o
the AG100, which should read near 50 psi (3.4 bar).
If the AG100 is 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 both of the above are okay, the stainless steel
o
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 hose barb (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.
