WARNING
Read this manual completely and understand the
machine before operang or servicing it.
• Always wear protecve clothing, gloves, and eyewear
while operang or servicing unit.
• Avoid contact of cleaning agent with skin and eyes. If
contact occurs, see Safety Data Sheet (SDS) sheet for
further rst aid measures.
• Follow safety instrucons of chemical manufacturer SDS.
• Never point the discharge wand at anyone.
• Incoming air pressure cannot exceed 100 psi (7 bar).
• Aer 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.
• Aer relieving the pressure from the unit, store the unit
with the ball valve in the closed posion.
• Be sure to ush the unit with fresh water for 5 minutes
when switching from an alkaline to an acid or an acid to
an alkaline.
• Do not exceed a uid temperature of 100˚F (37˚C).
• Only use clean and dry air. Air must be ltered and free
of moisture or pump life will be diminished. If needed,
install an air dryer before unit.
• Do not use air lubricator before the unit.

READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT
Operaon Instrucons:
1. Follow all instrucons from chemical manufacturer.
Fill the tank with water and the advised percentage of
chemical concentrate.
2. With ball valve (HV60) in the closed posion, plug an air
line into the air ng (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 direcon.
b. Open needle valve in counter-clockwise direcon 3
complete turns.
c. Connue to open valve in ¼ turn increments allowing 30
seconds between adjustments unl proper consistency
of foam is achieved.
Aer Use Instrucons:
1. Flush the unit with fresh water for 5 minutes.
2. Disconnect the air line from the air ng (AP25) and
relieve any remaining pressure in the system by opening
the discharge ball valve (HV60).
3. Close the ball valve (HV60) aer all pressure has been
relieved from the system.
Maintenance Instrucons:
To keep your portable tank foamer operang 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 condion and properly secured.
• Replace lter (AFR25) in regulator (R25) as needed.
• Check the sucon tube and screen for debris and clean as
needed.
• Drain compressor tank on a regular basis to ensure proper
operaon of pump.
Troubleshoong Instrucons:
• Check to ensure the discharge hose is uncoiled properly,
and that there are no kinks that could obstruct uid ow.
• Check air regulator bowl (ABR25) for debris such as
water, oil, or rust parcles. 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
Operaon Instrucon #4.
• Make sure proper foaming chemical and concentraon is
being used.
• If air passes through the pump (P56/P56K/P56V) without
cycling, the pump needs to be replaced.
• If foam soluon backs up into air regulator bowl (ABR25),
the check valve (CV38) needs to be replaced.
• If foam comes out wet, no maer where the needle valve
(NV14Y) is posioned, 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). Operang
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:
o Check the air compressor supplying the unit. If the
pressure is less than 40 psi, turn the foam unit o
unl the compressor can catch up.
o If the air supply is 50 psi (3.4 bar) or above, check 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).
o If both of the above are okay, the stainless steel
mixing mesh (SS-MESH) could be plugged. Remove
and clean it by following the instrucons 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 posion.
2. Remove the stainless adaptor (SSA12) from the
tee ng (SST12HB38).
3. Remove the screen and the mixing mesh from
inside the tee ng (SST12HB38).
4. Clean any parcles 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 ng
(SST12HB38). If the mixing mesh has a lot of
foreign parcles in it, make sure the strainer
(STR38-IL) is sll in place.
• Check for plugged strainer (STR38-IL). Replace strainer if
necessary. Strainer must be used.
