NOTE: The portion control valve does not have a top-off function.

tons to return to the factory portion settings.
NOTE: Portion controls will not operate below 22 volts. This is known as the
“brown-out feature”.
5.2 UF-1 and UFB-1 Optifill
TM
Valve
The Optifill
TM
Valve is activated by pressing a cup against the dispens-
ing 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 pre-
set 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 elec-
trical 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
TM
valve.

Valve Programming
The Optifill
TM
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.
