NOTICE
Servicing or modifying this unit with parts not listed in this manual may cause the unit to operate improperly. Do not use unauthorized parts when servicing the unit. Use of an air lubricator before the unit may result in diminished performance and damage to the unit. Do not use an air lubricator before the unit. Moisture in the air lines will damage the pump and diminish the pump life. The air must be filtered, clean, dry and free of moisture. If needed, install an air dryer before the unit.
PROTECT THE ENVIRONMENT
Please dispose of packaging materials, old machine components, and hazardous fluids in an environmentally safe way according to local waste disposal regulations.

Service Guide
WARNING
Performing any maintenance with the unit pressurized and connected to the air supply may result in serious injury or death. Always ensure that the unit has been depressurized and disconnected from the air supply before conducting any maintenance. Servicing or modifying this unit with parts not listed in this manual may cause the unit to operate improperly. Do not use unauthorized parts when servicing the unit.

Maintaining Your Unit

To keep your unit operating properly, periodically perform the following maintenance procedures:

· Inspect the pump for wear and leaks.
· Inspect all hoses for leaks or excessive wear. Ensure hose clamps are in good condition and properly secured.
· Check the air trigger port on the handle for debris and clean as needed. When cleaning, be careful not to push debris into the port, as it may become lodged inside and create a blockage.
· Check suction line and strainer for debris. Clean as needed.

· Replace the filter located within the air regulator as needed. Clean by unthreading the air regulator bowl from the air regulator.
· Drain your air compressor tank on a regular basis to help extend pump life. An air source with a high moisture content will accelerate pump wear.
Note: If your air source has a high moisture content, install a water separator to the air fitting on backplate. See Page 8 for more details. (Back plate assembly)

Servicing Your Unit

Most repairs on the unit can be performed with the following tools:

· Crescent wrench (2x)

· #2 Phillips head screwdriver

· /16 in. (11 mm) open-ended wrench

· #3 Phillips head screwdriver

· Flat head screwdriver

· Hose cutters

· Thread seal tape

· Knife

Troubleshooting Your Unit

If your unit is not operating properly, try using these troubleshooting tips:

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

· The needle valve is open too far. Close and readjust the needle valve as described in the
operation section.
· Ensure proper foaming chemical and concentration are being used.

Air passes through 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 air gauge. Air regulator is factory set at 50 psi (3.4) bar.
Operating range is 40 to 80 psi (2.8 to 5.5 bar) with 5 to 10 CFM (141.6 to 283.3 l/min).
· The check valve may need to be replaced.
· Verify correct chemical concentration is being used.

Unit activates when the air trigger port · Verify air trigger port is clean and free of blockages or debris, and discharge hose is not

is not covered

kinked or obstructed

· If the problem persists, try bypassing the air trigger. To do this, disconnect the 1/4 in. hose
from the wand. Point wand in a safe direction and connect an air line to the unit. Then, use your thumb or finger to seal the open port of the 1/4 in. hose at the wand.

1. If unit activates when you connect the air line, the valve block may need to be replaced.

2. If unit does not activate when you connect the air line, hose or wand assembly may need to be replaced.

Unit does not activate when air trigger · Confirm the incoming air supply is consistently 50 psi (3.4 bar) on the air gauge.

port is covered

· If the problem persists, the valve block may need to be replaced.

The unit operates at a reduced pressure

· Check 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 (2.8 bar),
turn off the unit 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 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. Verify the unit is not plugged into an air supply and then relieve all stored pressure in the unit by turning the ball valve to the open position.
2. Remove discharge hose from hose barb on back of the unit.
3. Open back plate assembly and hold stainless tee with wrench to remove hose barb from tee fitting.
4. Remove the screen and the mixing mesh from inside the tee fitting.
5. Clean any particles from the mixing mesh and the screen. If the mixing mesh has a lot of foreign particles in it, make sure the suction strainer is still in place.
6. Replace the mixing mesh and screen into the back of the tee. Screw the stainless hose barb back into the tee.
Note: It is recommended to use a pipe thread sealant when reinstalling the stainless hose barb back into the tee fitting.
