5. Troubleshooting
Issue Solution
Air regulator bowl or air
filter has debris such as
water, oil, or rust particles
• Clean by unthreading the air regulator bowl from the air regulator.
Pump is cycling improperly
due to lack of air pressure
• The flow control valve is open too far. Close and readjust the flow control valve as
described in the Operation section.
• Ensure proper foaming chemical and concentration are being used.
Air passes through the
pump without cycling
• The pump needs to be replaced.
The solution backs up into
the air regulator bowl
• The check valve needs to be replaced.
Foam comes out wet, no
matter where the needle
valve is positioned
• Check for proper air pressure on the air gauge. The air regulator 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
(141.6 to 283.3 l/min).
• The check valve may need to be replaced.
The unit operates at a
reduced pressure
• Check the chemical metering tip, suction line and strainer for debris or damage.
Clean or replace as needed. To prevent damage to the unit, the strainer must
always be used.
• Check the air compressor supplying the unit. If the pressure is less than 40 psi, turn
the unit o until the compressor can catch up.
• If the air supply is 50 psi (3.4 bar) or above, check the air gauge,
which should read near 50 psi (3.4 bar). If the air gauge reads more or less
than 50 psi (3.4 bar), adjust the pressure by turning the knob on the top of the
air regulator.
• Check if the stainless steel mixing mesh is 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 in the open
position.
2. Remove the stainless hose barb from the tee fitting.
3. Remove the screen and the mixing mesh from inside the tee fitting.
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. If the mixing mesh has a lot of foreign particles in it, make sure the
strainer is still in place.
