UF-1 and UFB-1 Valves Training Manual INTRODUCTION 1. PREVIEW QUESTIONS Check your current knowledge by taking a few minutes to answer the following questions: 1. What are the flow capacities of a UF-1 valve? _____________________________________ 2. What are the flow capacities of a UFB-1 valve? ____________________________________ __________________________________________________________________________ 3.
UF-1 and UFB-1 Valves Training Manual 3. OVERVIEW 3.1 Product Description The UF-1 and UFB-1 valve provides accurate flow capability and dependability. The UF-1 and UFB-1 valves are capable of flow rates of 1 ½ to 3 ounces per second (high flow), 2 to 4 ounces per second (UFB-1), or 3 to 4 ½ ounces per second (ultra flow). The valve flow control modules are the only parts that differ in the three versions.
UF-1 and UFB-1 Valves Training Manual There are four varieties of UF-1 and UFB-1 valves: • The cup activated valve dispenses by means of a lever engaged by the cup. • A push button valve has a press and hold button on the front cover of the valve. • • The OptifillTM valve dispenses with an activation lever but stops after the liquid fills the cup and touches the lever A portion control valve has four programmable drink size buttons that provide timed deliveries, top off, and a manual dispensing button.
UF-1 and UFB-1 Valves Training Manual Concentrate valve sleeve has only one hole INTRODUCTION A side water lever kit can be added to a valve allowing for dispensing of water without syrup or concentrate. The side water lever can be added to either a carbonated drink valve or a noncarbonated drink valve.
UF-1 and UFB-1 Valves Training Manual SYSTEM DETAILS 1. WATER 1.1 Water Quality Water quality issues have an affect on dispensing valves. Chloramine, a combination of chlorine and ammonia is responsible for some degradation of rubber components. Chloramine is used in many U. S. water supplies. Its affects can be minimized by installing and maintaining a water filtration system. Ultra pure water affects the sensitivity of the Optifill™ valve.
UF-1 and UFB-1 Valves Training Manual Lower Fluid Pressure BUT Higher Fluid Pressure BUT Same Volume Of Syrup/Water Flows From Orifices Knife edge Syrup/Water Flow Lower Fluid Pressure Pushing Against Piston & Spring Higher Fluid Pressure Pushing Against Piston & Spring The position of the piston inside the sleeve is determined by the upward pressure of the liquid against the base of the piston and the downward pressure of the spring inside the piston (not shown here).
UF-1 and UFB-1 Valves Training Manual Note: Always adjust water within its range. Water Flow Rates At Selected Ratios Water To Syrup Water at 1.5 oz./ Water at 3.0 oz./ Water at 3.75 oz./ Water at 4.5 oz./ Ratio sec. Total Flow sec. Total Flow sec. Total Flow sec. Total Flow 2 to 1 1.00 oz./sec. 2.00 oz./sec. 2.50 oz./sec. 3.00 oz./sec. 3 to 1 1.13 oz./sec. 2.25 oz./sec. 2.81 oz./sec. 3.38 oz./sec. 4 to 1 1.20 oz./sec. 2.40 oz./sec. 3.00 oz./sec. 3.60 oz./sec. 5 to 1 6 to 1 7 to 1 1.25 oz./sec. 1.29 oz.
UF-1 and UFB-1 Valves Training Manual 2. SYRUP/CONCENTRATE Syrup should always be precooled before setting the ratio. Syrup takes a path through the valve parallel to the water path. It is introduced in the block, travels through a syrup flow control, banjo, valve head and out the nozzle. Note, concentrate is not cooled. High sugar syrups are more viscous (thicker) than diet syrups and consequently have more pressure drop within a system.
UF-1 and UFB-1 Valves Training Manual 4. MECHANICAL 4.1 UF-1 and UFB-1 Valve Disassembly 1. Sequence for disassembly (refer to UF-1 Post-mix Dispensing Valve Illustrated Parts List) is as follows: 2. Remove front cover by lifting. SYSTEM DETAILS 3. Remove valve cover. Wiring Harness 4. Unplug wiring harness. © 1999-2005, IMI Cornelius, Inc.
UF-1 and UFB-1 Valves Training Manual 5. Remove valve from mounting block by pushing locking tab to left and push down on top plate of block. . Locking tab Locking tab Mounting screw 6. Remove water screw and lever (if it is installed on the valve). Water lever 7. Remove nozzle – turn left ¼ turn. SYSTEM DETAILS 8. Remove diffuser assembly. Note: The diffuser must be cleaned daily. Do not use bleach, do not use detergent, do not put in dishwasher. Use lukewarm water or soak in carbonated water. 9.
UF-1 and UFB-1 Valves Training Manual 12. Note that the flow rate (1 ½ - 3, 3 – 4 ½ or 1 ½ - 3 juice) and date code are printed on the retainer plate. Flow rate & date code 13. To disassemble the flow control: Remove screws and pull retainer forward. Remove top flow control subassemblies exposing flow controls. Note the difference between high flow and ultra flow valves. Concentrate valve sleeve has one hole Note: Top Flow control is an assembly and cannot be dissasembled.
UF-1 and UFB-1 Valves Training Manual 16. Then remove 5 screws that secure the valve head to the valve body. Pry here 17. To remove the dispensing lever return spring pry the end of the spring and pull up. This spring stops the lever from vibrating. 4.2 Mounting Block Disassembly To disassemble mounting block: 1. Turn off water and syrup supplies. SYSTEM DETAILS 2. Remove 2 screws from top plate and pull spools out from the bottom of the mounting plate exposing spools and O-rings.
UF-1 and UFB-1 Valves Training Manual 5. CONTROLS AND ELECTRICAL All UF-1 and UFB-1 valves have a 24 volt solenoid that should be powered by an 80 kVA rated transformer. Voltage at the coil with the solenoid energized should be 22 and 27 VAC. 5.1 UF-1 and UFB-1 Portion Control Valve The UF-1 and UFB-1 Portion Control Valves are push and release that dispense for a programmed duration. There are four settings: small, medium, large, and extra-large.
UF-1 and UFB-1 Valves Training Manual NOTE: The portion control valve does not have a top-off function. NOTE: When in programming mode, press and release any of the portion size buttons 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 OptifillTM Valve The OptifillTM Valve is activated by pressing a cup against the dispensing lever.
UF-1 and UFB-1 Valves Training Manual 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.
