STERILEX FI-EZB-15NV EZBlend Foam Unit
INSTRUCTIONS
WARNING
- Read all instructions before installing or operating unit.
- Always wear appropriate personal protective equipment(PPE) when operating or servicing unit.
- Always follow all chemical safety precautions and handling instructions provided by the chemical manufacturer and Safety Data Sheet (SDS).
- If this unit is modified or serviced with parts not listed in this manual, dilution rates may vary, or the unit may not operate correctly.
- Never point the discharge wand at yourself, another person, or any object you do not want covered in chemical.
- Always depressurize unit after use (as described in the After Use Instructions). Always store unit depressurized, with the discharge ball valve in the closed position.
- Do not exceed an incoming air pressure of 100 psi (7 bar).
- Do not exceed a fluid temperature of 100˚F (37˚C).
- Only use clean and dry air. Air must be filtered and free of moisture or pump life will be diminished. If needed, install a water separator before the unit.
- Do not use an air lubricator 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.
SPECIAL INSTRUCTIONS
This unit is specifically designed for use with Sterilex two-part liquid products. The unit is calibrated to achieve dilution rates as recommended by Sterilex of 12.8oz-16oz Solution 1: 12.8oz-16oz Solution 2: 1 gal water. One jug with a blue cap is labeled “Solution 1/Disinfectant Products” and should only be used with those Sterilex products categorized as “Solution 1/Disinfectant” products below. The other jug with a green cap is labeled “Solution 2/Activator Products” and should only be used with those Sterilex products categorized as “Solution 2/Activator” products below. Modifications to the unit will result in varied dilution rates that may minimize effectiveness of solutions or result in off label product usage. ALWAYS AFFIX STERILEX CHEMICAL JUG TAGS TO EACH JUG. CONTACT YOUR STERILEX PRODUCT CHEMICAL VENDOR FOR JUG TAGS.

Operation
- Remove unit from packaging.
- Using EZBlend Chemical Dispensing Unit or other dispensing system:
- Fill 5 gallon jug with blue cap with Sterilex “Solution 1/Disinfectant” product and secure cap.
- Fill 5 gallon jug with green cap with Sterilex “Solution 2/Activator” product and secure cap.
NOTE: Refer to the Acceptable Products chart if needed.
- Connect the chemical intake lines to the chemical containers.
- Connect the blue chemical intake line to the blue cap jug.
- Connect the green chemical intake line to the green cap jug.
- Fill the 15 gallon tank with water.
- Verify that the valve at the base of the suction line is open, to allow fluid into the suction line.
- With the discharge ball valve in the closed position, plug an air line into the air fitting.
- Slowly open the discharge ball valve to begin foaming. The discharge ball valve should be completely open while foaming.
- 8. Unit is pre-set to a standard needle valve setting to deliver product at labeled rate. If adjustment is needed for foam consistency or dilution, see Adjustment for Foam Consistency and Dilution Instructions.
NOTE: It is a best practice to always confirm chemical dilution with titration after adjusting needle valve.
Use titration kit available from Aqua Phoenix Scientific (US part number – TK3319-Z; Canada part number – TK3319FR) when titrating Sterilex products.
9. To stop foaming, close the discharge ball valve. Disconnect the air line from the air fitting and relieve any remaining pressure in the system by opening the discharge ball valve.
After-Use
- Thoroughly flush the unit with fresh water.
- . Disconnect both blue and green chemical intake lines from the chemical jugs.
- Connect the air line to the air fitting and open the discharge ball valve to dispense water for at least one minute.
- Close the discharge ball valve. Disconnect the air line from the air fitting and relieve any remaining pressure in the system by opening the discharge ball valve.
- Close the ball valve after all pressure has been relieved from the system. Store the unit with the discharge ball valve in the closed position.

Maintenance
To keep your foam unit operating properly, periodically perform the following maintenance procedures:
Note: Before performing any maintenance, ensure that the unit has been disconnected from the air and water supply and depressurized according to the After Use Instructions.
- Inspect the pump for wear and leaks.
- Inspect all hoses for leaks or excessive wear. Make sure all hose clamps are in good condition and properly secured.
- Replace the filter located within the air regulator as needed. Clean by unthreading the air regulator bowl from the air regulator.
- Check the chemical metering tips, suction lines and strainer for debris and clean as needed.
- 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, you may wish to install a water separator before the unit.
Troubleshooting
- Check to ensure that the discharge hose is uncoiled properly, and that there are no kinks that could obstruct fluid flow.
- Check the air regulator bowl and air filter for debris such as water, oil, or rust particles. Clean by unthreading the air regulator bowl from the air regulator.
- If the needle valve is open too far, the pump may cycle improperly due to lack of air pressure.
- If air passes through the pump without cycling, the pump needs to be replaced.
- If solution backs up into the air regulator bowl, the check valve needs to be replaced.
- If foam comes out wet, no matter where the needle valve is positioned, the check valve may need to be replaced.
- Check for proper air pressure on the air gauge. The air regulator is factory set at 60 psi (4.1 bar). Operating pressure is 60 psi (4.1 bar) with 5 to 10 cfm (141 to 283 l/min).
- If the unit operates at a reduced pressure:
- Check the air compressor supplying the unit. If the pressure is less than 60 psi, turn the unit off until the compressor can catch up.
- If the air supply is 60 psi (4.1 bar) or above, check the air gauge, which should read near 60 psi (4.1 bar). If the air gauge reads more or less than 60 psi (4.1 bar), adjust the pressure by turning the knob on the top of the air regulator.
- If both of the above are okay, the stainless steel mixing mesh could be plugged. Remove and clean it by following the instructions below:
- 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.
- Remove the stainless hose barb from the tee fitting.
- Remove the screen and the mixing mesh from inside the tee fitting.
- Clean any particles from the mixing mesh and the screen.
- 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.
- Check the chemical metering tips, suction lines and strainer for debris or damage. Clean or replace as needed. To prevent damage to the unit, the strainer must always be used.
- If concentrated product is back flowing into the water tank, the check valve needs to be replaced.
Adjustment for Foam Consistency and Dilution Instructions:
Note: Always confirm chemical dilution with titration after adjusting needle valve.
- If needle valve adjustment is needed for better foam consistency, while the unit is running and discharging product, adjust the needle valve as needed to regulate the wetness or dryness of the foam following the steps.
- For minor adjustment, turn the needle valve handle in 1/8 turn increments allowing 30 seconds between adjustments, until desired consistency of foam is achieved.
- Open needle valve in counter-clockwise direction for dryer foam.
- Close needle valve in clockwise direction for wetter foam.
- If your dilution is not within the labeled rate:
- To decrease concentration, open needle valve counter-clockwise.
- To increase concenration, close needle valve clockwise.
