2. Check the dispensing valves for dripping that indicates leakage and repair as necessary. ADJUSTMENTS CO2 REGULATORS ADJUSTMENTS WARNING: CO2 displaces oxygen. Strict attention must be observed in the prevention of CO2 (carbon dioxide) gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the contaminated area before attempting to repair the leak.
WATER FLOW REGULATOR SYRUP FLOW REGULATOR INNER NOZZLE Counterclockwise to Decrease NOZZLE SYRUP DIVERSION TUBE Clockwise to Increase RATIO CUP FIGURE 8. UF-1 DISPENSING VALVE ADJUSTING WATER-TO-SYRUP “RATIO” (BRIX) OF DISPENSED PRODUCT (see Figure 8) NOTE: Make sure the dispensing valve water flow rate is as desired before adjusting the valve for Water-to-Syrup ‘‘Ratio’’(Brix) of the dispensed product.
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. 6. Repeat water-to-syrup ratio test and adjust syrup flow regulator as many times as necessary until proper ratio of dispensed drink is achieved. 7. Remove syrup diversion tube assembly from dispensing valve. 8. Install dispensing valve front cover. CLEANING AND SANITIZING DAILY CLEANING OF UNIT 1.
Bag-in Box Syrup Systems. C. Install bag valves, cut from empty bag-in-box syrup containers, on ends of syrup containers syrup outlet tubes connectors. D. Place all syrup outlet tubes, with bag valves on their ends, in container containing detergent solution. 5. Flush the syrup system and dispensing valve as follows: A. Place waste container under applicable dispensing valve.
B. Activate the dispensing valve for one minute to purge all water from and install sanitizing solution in the syrup system and dispensing valve. C.
25. Dispose of waste sanitizing solution in a sanitary sewer, not in a storm drain, then thoroughly rinse the inside and the outside of the container that was used for sanitizing solution to remove all sanitizing solution residue. CLEANING DROP-IN REFRIGERATION ASSEMBLY CONDENSER COIL (see applicable Figure 6 or 7) CAUTION: The refrigeration assembly condenser coil must be cleaned every 30-days.
CLEANING WATER TANK (see Figure 6) 1. Unplug the Unit power cord from electrical outlet. 2. Close shutoff valve in plain water source line connected to the Unit. 3. Remove two screws securing the Unit front access panel, then remove the panel. 4. Extend the water tank drain hose (located on front of Unit) to a waste container or floor drain. Remove plug from end of the drain hose and allow the water tank to drain. 5. Remove screw securing the hood, then lift the hood straight up to remove from the Unit. 6.
17. Dispense from one of the dispensing valves to make the carbonator cycle on and off. 18. Check for water leaks and repair if leaks are found. 19. Install Unit hood and secure with screw. 20. Install Unit front access panel and secure with two screws.

TROUBLESHOOTING IMPORTANT: Only a qualified Service Person should service internal components or electrical wiring. DANGER: Disconnect electrical power to the Unit to prevent personal injury before attempting any electrical repairs to the internal components. If repairs are to be made to one of the syrup systems, disconnect syrup supply from the system, then bleed system pressure before proceeding.
Trouble Probable Cause Remedy ADJUSTMENT OF DISPENSING VALVE SYRUP REGULATOR DOES NOT DECREASE TO DESIRED WATER-TO-SYRUP ‘‘RATIO’’. A. Dirty or inoperative dispensing valve syrup flow control. A. Disassemble and clean dispensing valve syrup flow regulator. DISPENSED PRODUCT CARBONATION TOO LOW. A. Carbonator CO2 regulator out of adjustment for existing water conditions or temperature. A. Adjust carbonator CO2 regulator as instructed. B. Air in carbonated water tank. B.
Trouble DISPENSED PRODUCT PRODUCES FOAM AS IT LEAVES DISPENSING VALVE. (cont’d) Probable Cause F. Dirty water supply. Remedy F. Check water filter. Replace cartridge (see NOTE). NOTE: If water supply is dirty, be sure to flush lines and carbonator carbonated water tank completely. It may be necessary to remove lines to the carbonated water tank, invert the tank, then flush tank and all inlet lines to remove any foreign particles or dirt.
Trouble COMPRESSOR DOES NOT OPERATE.(CONT’D) COMPRESSOR WILL NOT STOP AFTER SUFFICIENT ICE BANK IS PRODUCED. COMPRESSOR OPERATES CONTINUOUSLY BUT DOES NOT FORM SUFFICIENT ICE BANK. Probable Cause Remedy G. Inoperative overload protector or start relay. G. Replace inoperative part. H. Inoperative ice bank control. H. Replace ice bank control. I. Inoperative compressor. I. Replace compressor. A. Ice bank control probe damaged. A. Replace ice bank probe. B.
