5.2 UF-1 and UFB-1 Optifill

The Optifill

Valve is activated by pressing a cup against the dispensing lever. The valve

dispenses only until foam from the cup touches the lever.* If a top-off delay is set, the

valve will dispense again after a preset delay. This “topping-off” fills the cup after the

foam settles. The top-off delay is can be adjusted from 0 to 15 seconds, the factory

default is 2 seconds.

*Note: A metal rivet in the valve body supplies electricity through the beverage being

dispensed. When the foaming beverage comes in contact with the metal dispensing

lever it completes the electrical circuit and the flow module closes the dispensing valve

— even though the lever is still activated.

Note: The cup must stay in place against the lever for the top-off to operate.

Note: A slanted cup rest must be used with an Optifill

valve.

Optifill Valve Programming

The Optifill

valve module provides a timed dispensing function to set water flow rates. To access this

function:

1. Press the program switch until the LED turns on.

2. Hold a graduated cup under the valve nozzle without touching the lever. Press the large rectangular

switch. The valve dispenses for 2 seconds. The dispensed liquid divided by 2 equals the oz./sec dispensed

rate.

3. Press the program switch to exit the program.

4. To program the top off function follow this procedure:

5. Remove the front valve cover.

6. Press the program switch until the LED turns on (can be seen from the top of the module.)

7. Place cup against the lever for initial dispensing. When the foam touches the lever the valve stops and the

LED flashes.

8. When the foam in the cup has lowered, press and release the large rectangular button. The valve dispenses

a top-off and shuts off when the foam again touches the lever. The LED is now on steady.

9. Press the program switch until the LED turns off.

10. If you wish to disable the top-off, follow steps 1 through 3. Remove the cup from the lever. This will enter

a zero value for the delay time and disable the top-off fill. Press the program switch for 3 seconds.
