Safety & Operational Precautions
When connecting to a potable water supply follow all local codes for backflow prevention.
For proper performance do NOT modify, substitute nozzle, hose diameter or length.
Manufacturer assumes no liability for the use or misuse of this unit.
Wear protective clothing, gloves and eye wear when working with chemicals.
Always direct the discharge away from people and electrical devices.
For pressures over 100 PSI, remove the discharge valve or lower pressure.
Never leave inlet ball valves on when unit is not in use.
Follow the chemical manufacturer's safe handling instructions.
NEVER mix chemicals without first consulting chemical manufacturer.
TO INSTALL (REFER TO DIAGRAM IN THE NEXT SLIDESHOW)
1. Mount the unit to a suitable surface above the chemical supply to prevent siphoning.
2. Connect the discharge hose.
3. When connecting to a potable water supply follow all local codes for backflow prevention.
4. Connect water supply. To prevent blocking the small water jets in the foamer body, flush any new plumbing of
debris before connecting. If water piping is older and has known contaminants, install a filter.
5. Connect air supply. If air line is older and has known contaminants install a filter.
Set the chemical dilution ratio by installing the inline tip holder and a metering tip into chemical pick up tube. See chemical label for dilution ratio recommendation or consult your chemical supplier.
For the strongest possible chemical dilution ratio, do not install a metering tip.
The dilution ratios in the metering tip chart are based on chemical with a viscosity of 1CPS.
For water pressure other than the example, use the Metering Tip Selection Formula.
Due to varying chemical viscosity and applications, you may need to increase/decrease the tip size to get the best
Install a colored metering tip in the inline tip holder and insert into the chemical pick up tube as shown in the
drawing. Use the provided clamp.
Once metering tip is installed immerse the chemical strainer into your chemical concentrate.
Always make sure the discharge ball valve is closed or pointed in a safe direction before turning inlet valve on. Discharge valve can be shut off at any time during operation but should not be left off for long periods of time with the inlet valve on.
1. Make final metering tip adjustments based on application results.
2. With wand in hand open the water ball valve, and the air ball valve.
3. Open the discharge ball valve.
Wait a few seconds and observe foam consistency.
Use the least amount of air needed to achieve good foam quality to prevent water pressure fluctuations
from affecting performance. Air pressure must be kept lower than water pressure.
To adjust the foam consistency pull out on the air regulator knob, turn slightly clockwise for dryer foam and
counterclockwise for wetter foam. Wait a few seconds to see each adjustment.
Medium wet foam will give the best cleaning results! Dry foam will NOT clean as well!
You may also have to try different sized metering tips and air settings until foam consistency and cleaning
results are acceptable. Once this is set and desired foam consistency is achieved push lock the knob on
the air regulator. You are ready to start application.
4. When foaming is completed, close the discharge ball valve, return to the unit and close the water and air ball
valves. Briefly re-open the discharge ball valve to relieve pressure in the hose.
5. Rinse before the foam dries.
