Possible Causes

Checks & Remedies

Sporadic Wet Foam

Improper mixture of cleaning solution.

Make sure the chemical is a foaming chemical.
Make sure the chemical is mixed at a high enough concentration to produce foam.

Constant Wet Foam

Wet Foam/Dry Foam valve may not be open far enough.
Air check valve may be plugged.

Clean the strainer.

Unit Foams at Reduced Pressure

Compressed air supply may not be adequate to run the unit.
Internal air regulator may be turned down too low.
S.S. mesh in the tee may be plugged.

A larger air compressor or air line needs to be used to supply enough air to the unit.
Adjust the air regulator to 40 - 60 psi.
Remove, clean & replace the S.S. mesh.

Only Air Discharges from the Foam Wand.

Wet Foam/Dry Foam valve may be open
too far, not giving air to the pump.
Pump may not be cycling.

Turn Wet Foam/Dry Foam valve clockwise until
the pump begins to run consistently.
Replace the pump.

Cautions

• Always follow all safety and warning instructions on the chemical label and MSDS sheet for the chemical being used through the FOAM-iT unit.

• Always wear safety goggles, protective gloves, and all other necessary protective clothing specified by the chemical's MSDS sheet while operating or servicing any FOAM-iT units.

• Always make sure the unit is depressurized before servicing the unit. Never point the discharge wand toward anyone.

• Avoid spraying in areas where water or chemical can cause damage.

• After each use, turn off the air supply to the FOAM-iT unit and relieve all remaining pressure in the unit by opening the discharge ball valve.

• Thoroughly flush the unit with water whenever switching from one chemical to another.
