Read this manual completely and understand the
machine before operang or servicing it.
• Always wear protecve clothing, gloves, and eyewear
while operang or servicing unit.
• Avoid contact of cleaning agent with skin and eyes.
If contact occurs, see SDS sheet for further rst aid
measures.
• Read chemical’s Safety Data Sheet (SDS) before using this
unit.
• Never point the discharge wand at anyone.
• Incoming air pressure cannot exceed 100 psi (7 bar).
• Aer 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.
• Aer relieving the pressure from the unit, store the unit
with the ball valve in the closed posion.
• 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.
PROTECT THE ENVIRONMENT
Please dispose of packaging materials, old machine
components, and hazardous uids in an environmentally safe
way according to local waste disposal regulaons.
Always remember to recycle.
*Specicaons and parts are subject to change without noce.

Operaon Instrucons:
1. Follow all instrucons from chemical manufacturer.
Fill the tank with water and the advised percentage of
chemical concentrate.
2. With ball valve (HV60) in the closed posion, 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 direcon.
b. Open needle valve in counter-clockwise direcon 3
complete turns.
c. Connue to open valve in ¼ turn increments allowing 30
seconds between adjustments unl proper consistency
of foam is achieved.
Aer Use Instrucons:
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) aer all pressure has been
relieved from the system.
Maintenance Instrucons:
To keep your portable tank foamer operang 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 condion and properly secured.
• Replace lter (AFR25) in regulator (R25) as needed.
• Check the sucon tube and screen for debris and clean as
needed.
• Drain compressor tank on a regular basis to ensure proper
operaon of pump.
Troubleshoong Instrucons:
• 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 parcles. 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
Operaon Instrucon #4.
• Make sure proper foaming chemical and concentraon is
being used.
• If air passes through the pump (P56/P56K/P56V) without
cycling, the pump needs to be replaced.
• If foam soluon backs up into air regulator bowl (ABR25),
the check valve (CV38) needs to be replaced.
• If foam comes out wet, no maer where the needle valve
(NV14Y) is posioned, 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). Operang
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
unl the compressor can catch up.
o 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).
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 instrucons 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 posion.
2. Remove the stainless adaptor (HBSS1234) from
the tee ng (SST12HB38).
3. Remove the screen and the mixing mesh from
inside the tee ng (SST12HB38).
4. Clean any parcles 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 parcles in it, make sure the strainer
(STR38-IL) is sll in place.
• Check for plugged strainer (STR38-IL). Replace strainer if
necessary. Strainer must be used.
