Strict attention must be observed in the prevention of (carbon dioxide) gas leaks in the entire CO suspected, particularly in a small area, immediately ventilate the contaminated area before attempting to repair the leak.
Request a written inspec- tion report from Claims Inspector to substantiate any necessary claim. File claim with the delivering carrier, not with IMI Cornelius Inc. 1. After the Unit has been unpacked, remove shipping tape and other packing material.
NOTE: IMI Cornelius Inc. recommends that a water shutoff valve and water filter be installed in the plain water inlet supply line (see applicable Figure 2 or 3) . A Cornelius Water Filter (P/N 313860000) and Quick Disconnect Set (P/N 313867000) are recommended.
IMPORTANT: TO THE INSTALLER. It is the responsibility of the Installer to ensure that the water supply to the dispensing equipment is provided with protection against backflow by an air gap as defined in ANSI/ASME A112. 1.2-1979; or an approved vacuum breaker or other such method as proved effective by test.
1. Route syrup source lines from the syrup tanks location up to location under the countertop. 2. Route syrup source lines up through hole cut in the countertop to the barbed and labeled syrup inlet lines on front of the Unit. 3.
3. Install plug in water fill hole. 4. 115 VAC, 60 H Units. Make sure the main power switch on right side of the Unit (see Figure 5) is in the “ OFF”position. 115 VAC, 60 H Units and 230 VAC, 50 H Make sure the carbonator water pump motor power switch located on the drop-in refrigeration assembly electrical control box (see Figure 5) is in the “...
3. Open the plain water inlet supply line shutoff valve. Check for water leaks and tighten any loose connections. 4. Place the carbonator water pump motor power switch (located on the refrigeration assembly control box) in the “ ON”position.

NOTE: To readjust CO regulator to a lower setting, loosen adjusting screw lock nut, then turn screw to the left (counterclockwise) until pressure gage reads 5 psi lower than new setting will be. Turn the ad- justing screw to the right (clockwise) until the gage registers new setting, then tighten the lock nut. Adjusting Carbonator CO Regulator.
4. Install syrup separator on dispensing valve in place of the nozzle. 5. Measure the water flow rate by dispensing water into a graduated cup for a set period of time. Factory-set flow rate is approximately 1.25 ounces per second. 6.
ADJUSTING WATER-TO-SYRUP “RATIO” (BRIX) OF DISPENSED PRODUCT SF-1 Dispensing Valve. (see Figure 6) NOTE: Make sure the dispensing valve water flow rate is as desired before adjusting the valve for Wa- ter-to-Syrup ‘ ‘ Ratio’ ’(Brix) of the dispensed product. Adjust Water-to-Syrup ‘...
5. Adjusting Syrup Flow Regulator -- If water and syrup levels are uneven in the ratio cup, adjust by turning the dispensing valve syrup flow regulator adjusting screw labeled SYRUP as follows. For less syrup, turn the adjusting screw counterclockwise no more than 1/4 turn at a time. For more syrup, turn the adjusting screw clockwise no more than 1/4 turn at a time.
CLEANING WATER TANK (see Figure 5 and 8) 1. Unplug Unit power cord from electrical outlet. 2. Shut off plain water supply to the Unit. 3. Note pressure setting on the primary CO screw to the left (counterclockwise) until gage reads 0-psig. 4.
24. Plug Unit power cord into electrical outlet. 25. Dispense from one of the carbonated drink dispensing valves to bleed all air from the Unit carbonated water tank and the carbonated water system. 26. Check for leaks and repair if evident. 27.
5. Remove nozzle and syrup diffusers from the dispensing valves. Place nozzles and syrup diffusers in sani- tizing solution. 6. Wash the nozzles and syrup diffusers in sanitizing solution, then rinse them with potable water. 7. Re-install nozzles and syrup diffusers back on the dispensing valves. SANITIZING POST-MIX SYRUP SYSTEMS IMPORTANT: Only qualified Service Personnel should perform sanitizing procedure on the post-mix syrup systems.

Fill five-gallon container with potable water, then place all bag-in-box syrup containers syrup outlet tubes in container containing potable water. 9. Flush detergent solution out of the syrup system and dispensing valve as follows: Place waste container under applicable dispensing valve. Activate the dispensing valve for one minute to purge all detergent solution and flush out the syrup system.
Place all bag-in-box syrup containers syrup outlet tubes in container containing potable water. 20. Flush sanitizing solution from the syrup system and the dispensing valve as follows: Place waste container under applicable dispensing valve. Activate the dispensing valve for one minute to purge all sanitizing solution out of the syrup system and the dispensing valve.

IMPORTANT: Only qualified personnel should service internal components or electrical wiring. WARNING: If repairs are to be made to a product system, remove quick disconnects from the applicable product tank, then relieve the system pressure before proceeding. If repairs are to be made to the CO system pressure before proceeding.
Trouble ADJUSTMENT OF DISPENSING VALVE SYRUP FLOW CONTROL DOES NOT DECREASE TO DESIRED WATER-TO-SYRUP “ RATIO” . DISPENSED PRODUCT CARBONATION TOO LOW. DISPENSED PRODUCT COMES OUT OF DISPENSING VALVE CLEAR BUT FOAMS IN CUP OR GLASS. NOTE: Crushed ice also causes dispensing problems. When dispensed drink hits sharp edges of ice, carbonation is released from drink.
Trouble DISPENSED PRODUCT PRODUCES FOAM AS IT LEAVES DISPENSING VALVE.(CONT’ D) NO PRODUCT DISPENSED FROM ALL DISPENSING VALVES. ONLY CARBONATED WATER DISPENSED. ONLY SYRUP DISPENSED. 312027000 Probable Cause Dirty water supply. NOTE: If water supply is dirty, be sure to flush lines and carbonator completely.
TROUBLESHOOTING REFRIGERATION SYSTEM Trouble COMPRESSOR DOES NOT OPERATE. COMPRESSOR WILL NOT STOP AFTER SUFFICIENT ICE BANK IS PRODUCED. (NOTE: ICE BANK SHOULD JUST COVER CONTROL BULB). Probable Cause Ice bank sufficient. Unit power cord unplugged, power switch (if applicable) in “...
Trouble COMPRESSOR OPERATES CONTINUOUSLY BUT DOES NOT FORM SUFFICIENT ICE BANK. AGITATOR MOTOR NOT OPERATING. 312027000 Probable Cause Cooling capacity is exceeded by over-drawing. Unit located in excessively hot area or air circulation through condenser coil is restricted. NOTE: Ice bank freezes from bottom of evaporator upward. A refrigerant leak or insufficient charge might show an ice bank at bottom and not at top of evaporator.
