Overview
The Vision Satellite Entryway Foam Sanitizer is an automated foam applicator for projecting sanitizing chemicals on to floors of 3' wide employee walk doors
to prevent cross contamination. When activated, this venturi injection system uses city water pressure (35 - 125 PSI) to draw and blend chemical concentrate
into the water stream to create an accurately diluted solution. Rich, clinging foam is created by injecting compressed air into the solution to greatly increase
volume and coverage ability. Foam is then projected through the discharge hose and Spreader™ nozzle. Vision Satellite units are activated by compressed
air from the Vision Controller and operated by compressed air local to the satellite - No electrical connection is required at the entryway location. The Vision
Controller features highly flexible programmable settings with multiple options to precisely manage the foam sanitizing of up to six zones of multiple doorways
with independent settings for each zone.

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.
Follow the chemical manufacturer's safe handling instructions.
NEVER mix chemicals without first consulting chemical manufacturer.
TO INSTALL (REFER TO DIAGRAM, NEXT PAGE.)
Note: An independent 3/8" compressed air supply line should be installed, starting from a central Lafferty Vision
Controller and extending to each location where a Vision Satellite will be installed.
1. Mount the Satellite to a suitable surface above chemical supply to prevent siphoning.
2. See Page 1 for proper installation layout.
3. You can use either the supplied section of hose to connect the foamer to 3/4" pipe or use 3/4" ID pipe only.
Minimum length of the total hose/pipe is 25'. Use as few elbows as possible
4. Connect and mount the spreader nozzle slot at around 4-5” off the floor.
5. Connect local compressed air supply to the unit.
6. Close air ball valve.
7. Connect air supply line from the central Lafferty Vision Controller to the unit.
8. Connect water supply.
Set the chemical dilution ratio by threading one of the color coded metering tips into each chemical check valve.
See chemical labels for dilution ratio recommendation or consult your chemical supplier.
For the strongest dilution ratio do NOT install a colored metering tip.
The dilution ratios in the metering tip chart are based on water thin chemicals with a viscosity of 1CPS.
Thicker chemicals will require a larger tip than the ratios shown in the chart.
Application results will ultimately determine final tip color.
Select the tip color that is closest to your desired chemical strength and thread it into the tip holder. DO NOT OVER
TIGHTEN.
Push the chemical tube over the check valve barb and place the strainer in the chemical concentrate.
TO OPERATE
Testing & Adjustment
The Vision Satellite Entryway Foam Sanitizer is equipped with an air ball valve. While testing and adjusting the unit, or in
case of an emergency, the unit can be shut off by closing the air ball valve completely. The unit will not operate when the
air ball valve is closed, regardless of Vision Controller settings. Do not use the air ball valve to control air flow. This ball
valve must be fully open for the unit to operate correctly.
Recommended Testing Procedure — You can temporarily, directly connect a separate compressed air supply to the unit.
In this case you would need to connect the air supply to both the local air inlet port and the air inlet from the Vision
Controller port.
1. Final metering tip/chemical dilution and air adjustments will now have to be made.
2. Open the air ball valve completely to activate the unit.
3. Wait a few seconds and observe foam consistency.
Use the least amount of air needed to achieve good foam quality to prevent solution pressure fluctuations
from affecting performance. Air pressure must be kept lower than solution pressure.
To adjust 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
You may also have to try different dilution and air settings until foam consistency is acceptable. Once this
is set and desired foam consistency is achieved push lock the knob. You are ready to start.
Testing Procedure when unit is connected to a Vision Controller:
1. Follow page 4 of the separate Vision Controller instructions to select the Zone for this Satellite unit, then set the Zone to Manual Operation for several minutes. Turn off
air to any additional satellite units that are connected to the same Zone. Follow steps 2 and 3 under Recommended Testing Procedure, above.
2. When testing is complete, close the air ball valve at the unit. Follow the Controller instruction manual to re-set the Controller for standard operation.
3. Re-open the air ball valve at all units to allow activation by the Vision Controller.

Possible Cause / Solution
Startup Maintenance
1. Air pressure too high
Adjust air regulator slowly counterclockwise until output stabilizes.
2. Air adjustment too low
Adjust air regulator very slowly clockwise.
3. Use of an oiler in the airline will cause poor foam quality
Use only clean, dry air.
4. Not enough chemical - metering tip too small
Install larger metering tip.
5. No metering tip installed or metering tip too large
Install smaller metering tip.
6. Improper chemical
Ensure product is recommended for foaming and/or the
application.
7. Chemical tube not immersed in chemical or chemical depleted
Immerse tube or replenish
8. Foam hose kinked or hose/plumbing too short or wrong size
(See REQUIREMENTS on page 1)
9. Water pressure too low or water volume too low/inlet piping too
small
Increase water pressure or water volume. (See REQUIREMENTS
on page 1)
10. No water to the unit
Ensure that the water supply is not shut off to the unit.
11. Timer failed/Controller not set properly or malfunctioned
Replace timer. See Controller manual.
12. May have electrical problems
Ensure circuit breaker (5 Amp) has not been tripped.
Have a qualified electrician check electrical connections.
13. Chemical check valve stuck or failed
Clean or replace.
14. Chemical strainer or metering tip partially blocked
Clean or replace chemical strainer and/or metering tip.
15. Chemical tube stretched out where tube slides over check valve or
pin hole/cut in chemical tube (sucking air in)
Cut off end of tube or replace tube.
16. Vacuum leak in chemical pick-up connections
Tighten the connections.
17. Air regulator failed allowing too much air or not enough air
Clean or replace.
18. Air check valve or air solenoid clogged or failed
Clean or replace.
19. Water solenoid clogged or failed
Clean or replace the water solenoid.
20. Chemical build-up may have formed in the body, causing poor or no
chemical pick-up
Follow PREVENTIVE MAINTENANCE instructions below, using
hot water or descaling acid. When there is no draw at all,
carefully remove fittings and soak entire body in descaling acid.
21. No backflow preventer installed
Install appropriate backflow preventer into water line.
PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush
the chemical out of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical
strainer and replace if missing.
