Installation Instructions:

1. Remove all components from packaging.
2. Select an area to mount the control box.
Note: The control box should be mounted to a vertical
wall. We recommend mounting the control box at a
height of 6 feet or less. 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.
3. Attach the control box mounting feet to the back of the
control box, using the four screws provided in the parts
package.
4. Mount the control box to the wall using four of the screws
and plastic anchors provided in the parts package.
Note: To drill holes for the plastic anchors, use a 5/16 inch
drill bit.
5. Mount the stainless steel nozzle assembly in the desired
location using the two stainless steel brackets, four of the
screws, and plastic anchors provided in the parts package.
Repeat as needed for multiple nozzles.
Note: The foam pattern dimensions provided in this
manual were measured with nozzle assemblies mounted
6 in. (15 cm) above the floor.
6. Run tubing from the solution outlet fitting on the control
box to the solution inlet fitting on the nozzle assembly.
For multiple nozzles, run the tubing from the control
box into a tee fitting, as shown in the diagram. Then, run
tubing from the tee fitting to the nozzle assemblies.
For systems with three nozzles, use a second tee fitting to
split the line again.
7. Run tubing from the air outlet fitting on the control box to
the air inlet fitting on the nozzle assembly. For multiple
nozzles, split the line using one or more tee fittings, as
described in step 6 and shown in the diagram.
Note: The air and solution lines must be routed to the
appropriate fittings (as labeled), 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.

8. Connect the air inlet hose barb provided in the parts
package to the air inlet valve located on the side of the
control box. Then attach a 3/8 inch I.D. air line from your air
compressor to the air inlet hose barb, and secure it with
the smaller hose clamp provided in the parts package.
9. Connect a water line to the unit. The control box has a 1/2
inch FPT water inlet fitting.
Note: A back-flow preventer must be installed in the
water line – check local plumbing codes to ensure proper
installation.
10. Open the cover of the control box. Insert the proper
metering tip and connect the chemical intake line to the
injector inlet barb.
Note: Use the included metering tip color chart to
determine the appropriate metering tip based on the
product and dilution rate you will be using.

** Injection rates will vary based on chemical
viscosity, air pressure, and many other factors. We
recommend testing unit output to verify injection
rate prior to use.
11. Place the other end of the chemical intake line into a
chemical container.
Note: The chemical suction line must reach the bottom
of the chemical container. A strainer must be used on the
chemical intake line.
12. Set the timer for the desired on time and off time, as
described in the Timer Adjustment Instructions.
