The UF-1 valve is capable of finished drink flow
rates of up to 4.5 Oz/Sec. This can cause some
difficulty if you are attempting to install the valve on
a piece of equipment or a system that is not
capable of those flow rates.

Just because the valve is capable of the higher flow
rate, it does not mean that the system or dispenser
can meet those needs.

Compare this to putting a 300 MPH speedometer
on your car – that doesn’t mean that you car can go
that fast.

Review the following information to ensure that the
installation of the UF-1 valve will provide the
performance that you desire. There are many
considerations so be sure to review all the various
parameters.

The UF-1 valve will provide satisfactory
performance only if the system supplying it is up to
the task.

Installation Considerations

Number of UF-1 Valves Side-By-Side
18 Inch Towers

An 18 inch wide tower IS NOT capable of accepting
six UF-1 Valves. If you are converting from SF-1 to
UF-1, and there were six SF-1 valves on the 18
inch wide tower, you will only be able to fit five UF-1
valves within the same width.

To complete this conversion, you must change the
valve mounting panel to the five valve configuration.
Valve mounting panels are available by calling the
800 number listed on page 30. Be SURE to have
the model and serial number of the tower
when you call.

Valve Requirements

The UF-1 valve requirements are as follows:

Flow Rates;

Water/Carb Water 1.25 to 3.74 Oz/Sec

Syrup .25 to .75 Oz/Sec

Operating Pressures at the Valve Inlet;

Non-Carb Water

(1.5 - 3.0 Oz/Sec)

Non-Carb Water

(3.0 - 4.5 Oz/Sec)

Carb Water 80 PSI to 110 PSI

Syrup – Sugar 20 PSI to 70 PSI

Syrup – Diet 8 PSI to 20 PSI*

*NOTE: Diet syrup pressure may be higher when B-I-B pumps are
being used.

Electrical;

Voltage 24 VAC

Transformer 80 VA or greater

30 PSI to 110 PSI

50 PSI to 110 PSI

CO2 Requirements;

The UF-1 valve does not require CO2 for it’s
operation. CO2 is used for the carbonation of water
and often used for the propulsion of syrup, either
with tanks or B-I-B pumps.

OPTIFILLT VALVES

The OptiFillt valve is a form of portion control with
unique features. Most important among it’s features
are:

1. OptiFillt will fill any size cup to FULL
regardless of the amount of ice in the cup or
the size of the cup.

2. Will automatically top-off the cup to
compensate for foam as with diet drinks.

3. No buttons to push, just set the cup in place
and it fills to the rim.

Important Grounding Notice

NOTE: The following instructions Do Not apply to units with the
White wire switched (connected to the Key Switch). All units must

be connected to a properly earth grounded outlet. Do Not use
ungrounded outlets.
The following information applies only to units that have the Black
wire switched through the key switch.

Units with Black Wire Switched

The OptiFillT control makes a low voltage electrical
connection to the dispensing beverage, therefore, it
is important that the dispensing chassis is
Earth-Grounded for safety. Use an Ohmmeter to
measure electrical continuity from the 24 Volt
connector (as shown) to the nearest cold water
metal pipe (such as the water supply to the
carbonator). If the chassis is not grounded,
connect a wire from the chassis to an acceptable
Earth-Ground (such as a cold water copper pipe) or
other electrical equipment that is Earth-Grounded.
