UF–1 DISPENSING VALVE
Notice: On a dispensing valve with adjust-
able water flow regulator make sure water
flow rate is adjusted to your requirement be-
fore adjusting the syrup to water ratio.
Adjust water–to–syrup ratio of dispensed product
by using ratio cup (P/N 311100–000) and syrup
diversion tube assembly
(P/N 319540–000) as follows:
1. Remove cover from the dispensing valve by
lifting front cover up 1/4 inch and pulling for-
ward.
2. Install syrup diversion tube assembly on dis-
pensing valve by pushing rubber end of syr-
up diversion tube onto the syrup outlet of
the inner nozzle.
Notice: Refer to syrup manufacturer’s recom-
mendations on syrup package for water-to-
syrup ratio.
3. Dispense enough to fill syrup diversion tube
with syrup.
4. Hold large chamber of ratio cup under dis-
pensing valve nozzle. Place free end of syr-
up diversion tube into syrup chamber
marked for proper ratio. Dispense approxi-
mately 6 ounces of water into ratio cup. Wa-
ter and syrup levels should be even in cup.
5. Adjusting Syrup Flow Regulator – If
water and syrup levels are uneven in ratio–
cup, adjust by turning dispensing valve syr-
up flow regulator adjusting screw labeled
SYRUP as follows.
A. For less syrup, turn the adjusting screw
counterclockwise no more than 1/4 turn
at a time.
B. For more syrup, turn the adjusting
screw clockwise no more than 1/4 turn
at a time.
Note: Adjusting screw stops are built into the
valve to prevent leakage when the screws are
adjusted clockwise too much. Stop adjust-
ing clockwise when turning resistance in-
creases. Turn the screw counterclockwise
1 1/2 turns after the stop are contacted.
