CONNECTING SOFT DRINK TANKS TO UNIT SYRUP SYSTEMS
IMPORTANT: Product shutoff valves, located in lines leading from product blender tanks to freeze
cylinders (see applicable Figure 2 or 3 and 7), must be closed at this time. Closing valves prevents
product from filling freeze cylinders while checking Brix of product in product blender tanks.
1. Close product shutoff valves, located in lines leading from product blender tanks to freeze cylinders, to
prevent product from entering cylinders.
IMPORTANT: The following CO

and liquid disconnects disconnecting and connecting procedure for
soft drink tank replacement or filling soft drink tank in place must be performed in order as follows:
To disconnect soft drink tank from Unit syrup system.
A. Disconnect liquid disconnect from soft drink tank. NOTE - Disconnecting liquid quick disconnect from
soft drink tank first prevents syrup from backflowing through Unit syrup flow regulator, which may alter
regulator adjustment.
B. Second, disconnect CO

quick disconnect from soft drink tank.
NOTE: The Two-flavor Unit is equipped with one control panel (see Figure 9) which controls operation
of the two freeze cylinders and the four-flavor Unit is equipped with two control panels, each control
panel controlling two of the four freeze cylinders. The Unit control panel is equipped with a hidden
‘‘SECURITY SWITCH’’ located between ‘‘FILL 1’’ and ‘‘ERROR RESET’’ control switches (see Figure
NO TAG). Pressing in and holding the ‘‘SECURITY SWITCH’’ for 10-seconds deactivates the control
switches to prevent any tampering with the Unit’s normal operation. To reactivate the control switches,
press in and hold the ‘‘SECURITY SWITCH’’ for 10-seconds.
2. Pressurize soft drink tanks containing syrup, then connect tanks to Unit syrup systems. ‘‘OFF 1’’, ‘‘OFF 2’’,
‘‘SYRUP 1’’, and ‘‘SYRUP 2’’ fault messages will continue to be displayed.
ADJUSTING BRIX (WATER-TO-SYRUP) ‘‘RATIO’’ OF DISPENSED PRODUCT
The following steps 1 through 9 are instructions for adjusting Brix (Water-to-Syrup ‘‘Ratio’’ (mixture) of
dispensed product on one of the two (two-flavor Unit) or one of the four (four-flavor Unit) systems.
Note: The adjustable carbonated water flow regulators (see applicable Figure 2 or 3 and 12 ) located in
their respective systems, control carbonated water flow rate to the product blender tanks. The water
flow regulators are factory adjusted at 1.3 0.05 oz/sec. and should not normally require adjustment.
If adjustment is necessary, adjust as instructed.
1. Press ‘‘FILL 1’’ switch to fill No. 1 syrup system sold-out float. ‘‘SYRUP 1’’ fault message will go out and
‘‘FILL 1’’ fault message will come on. ‘‘OFF 1’’, ‘‘OFF 2’’, and ‘‘SYRUP 2’’ fault messages will continue to be
displayed.
2. Press ‘‘AUTO BLEND 1’’ switch to fill No. 1 system product blender tank with product. ‘‘FILL 1’’ fault
message will go out when ‘‘AUTO BLEND 1’’ switch is pressed. When product blender tank is full, press
‘‘FILL 1’’ switch to prevent more product from entering tank. ‘‘OFF 1’’, ‘‘OFF 2’’, and ‘‘SYRUP 2’’ fault
messages will continue to be displayed.
3. Open No. 1 product blender tank product sample valve (see applicable Figure 2 or 3 and 7) and take
sample (approximately 6-ounces) of product in a cup or glass.
NOTE: Temperature compensated hand-type refractometers (P/N 511004000) are available from the
Cornelius Company.
4. Check product Brix with a temperature compensated hand-type refractometer. Brix should read 13 ± 1. If
Brix is not within tolerance, adjust white syrup flow regulator for No. 1 syrup system as follows:
Turn regulator adjusting screw to the left (counterclockwise) no more than 1/8-turn at a time to reduce
syrup flow rate or turn screw to the right (clockwise) no more than 1/8-turn to increase flow rate.
5. Place container under No. 1 product sample valve. Open valve to purge product out of product blender
tank, line, and valve, then close valve. ‘‘OFF 1’’, ‘‘OFF 2’’, and ‘‘SYRUP 2’’ will continue to be displayed.
