Installation
Preparation
- Remove all components from packaging.
- Select an area to mount the control box.
Note: The control box should be mounted to a vertical wall. Mounting the control box at a height of 6 feet or less is recommended. The chemical suction line must reach the bottom of the chemical container. The bottom of the chemical container should not be positioned higher than the bottom of the control box.
- Select the area where the nozzle assembly will be mounted.
Note: Consider the foam pattern when selecting the number of nozzles and location. The foam pattern dimensions provided in this manual were measured with nozzle assemblies mounted 6 inches (15 cm) above the floor.
Assembly
- Attach the control box mounting feet to the back of the control box, using the four screws provided in the parts package.
- Mount the control box to the wall using four of the screws and plastic anchors provided in the parts package.
Note: Use a 5/16 inch drill bit to drill holes for the plastic anchors.
Diagram Description: Illustrates mounting the control box to a wall. Shows the control box with mounting feet attached. Indicates drilling into the wall (5) and the control box (4). Recommended mounting height is "6 feet max".
Area of Coverage
1 Nozzle | 2 Nozzles | |
Coverage | Up to 9x4 ft. (2.7x1.2 m) | Up to 5x3 ft. (1.5x0.9 m) at each nozzle |
Diagram shows nozzle assemblies mounted 6 inches (15 cm) above the floor.
- Mount the nozzle assembly in the desired location. Fasten the stainless steel bracket using the screws and plastic anchors provided in the parts package. Repeat this step if multiple nozzles are needed.
- Connect the tubing from the solution outlet fitting on the control box to the solution inlet fitting on the nozzle assembly.
Note: For multiple nozzles, run the tubing from the control box into a tee fitting, as shown in the Tee Fitting diagram below. Then, run tubing from the tee fitting to the nozzle assemblies.
Important! The solution line must be routed to the appropriate fittings or the foam quality of the unit will be negatively impacted. Make sure to insert the tubing all the way into the fittings to ensure proper connection.

Correct Connection: Shows a tee fitting. The inlet connects to the stem of the tee, leading to two outlets. Text: "Connecting the inlet to the stem of the tee creates even discharge from each side."
Incorrect Connection: Shows a tee fitting. The inlet connects to the side of the tee, leading to two outlets. Text: "Connecting the inlet to the side of the tee creates uneven discharge."
- Attach an air line from your air compressor to the control box.
- Set the Timer for the desired ON and OFF time (see Using your unit - Timer Setup for instructions).
- With the power switch in the OFF position, plug the unit into a power outlet.
- Connect the control box to the header supply line from the chemical room. Use the 1/2 in. NPT fittings provided.
- Ensure a shut off valve is between the header supply line and the control box. This will ensure the ability to deactivate the control box if it needs to be serviced.
Diagram Description: Shows the control box with various connections. Key connections include the solution outlet fitting (7) to the nozzle assembly, air line connection, header supply line connection (11), timer (9), power switch (10), and power cord (8).
Using your unit
Timer Setup
The timer is an adjustable repeat cycle timer with the ON time operating first. The timer will begin cycling when the unit is powered on.
To set the timer:
- Press SET to enter time adjustment mode. Press SET again to highlight the next value.
- Use ADJ to adjust the highlighted value. The time format is M:SS for ON time, and H:MM for OFF time.
- The timer will begin cycling with the new settings once all values have been set. The timer on screen will count down.
- Hold SET to restart the timer's cycle.
Diagram Description: Two digital timer displays are shown.
- On Time: Displays "0:15" (Minutes: Seconds). Features "SET" and "ADJ" buttons (1).
- Off Time: Displays "0:15" (Hours: Minutes). Features "SET" and "ADJ" buttons (2).
Operating Instructions
- Verify the unit is connected to compressed air, power, and chemical.
- To activate the unit, turn the power switch ON. The unit will begin cycling through the ON time and OFF time intervals set on the timer, beginning with the ON time.
- Open the needle valve (counter-clockwise) all the way on the fluid side of the control box. Reduce the air pressure to 10 psi or less. While the unit is running, slowly increase the air pressure until the desired foam quality is achieved.
Note: If foam volume is too high, turn fluid needle valve until desired flow of foam is achieved.
- To deactivate the unit, turn the power switch OFF.
Diagram Description: Shows the power switch (labeled "Power switch") and connections labeled "2" and "4". A close-up view shows a rotary dial (labeled "3"), identified as the fluid needle valve.
