AF 976734 • Vision Satellite Entryway Foam Sanitizer

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.
