Adjusting Brix (Water-To-Syrup) ''Ratio'' Of Dispensed Product; Filling Freeze Cylinders With Product - Cornelius FCB 3 H.P. POST-MIX DISPENSER Installation & Service Manual

ADJUSTING BRIX (WATER-TO-SYRUP) ''RATIO'' OF DISPENSED PRODUCT

NOTE: The Unit is equipped with one control panel (see Figure 4) which controls operation of the two
freeze cylinders. The Unit control panel is equipped with a hidden ''SECURITY SWITCH'' located
between ''FILL 1'' and ''ERROR RESET'' control switches (see Figure 4). Pressing in and holding the
''SECURITY SWITCH'' for 10-seconds deactivates the control switches preventing tampering with the
Unit normal operation. To reactivate the control switches, press in and hold the ''SECURITY SWITCH''
for 10-seconds.
The following steps 1 through 9 are instructions for adjusting Brix (Water-to-Syrup ''Ratio'' (mixture) of
dispensed product on one of the two systems.
Note: The adjustable carbonated water flow regulators (see Figure 2 and 13 ) 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 Figure 2) 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.
6. Press ''AUTO BLEND 1'' switch to run new batch of product into product blender tank. When product
blender tank is full, press
''FILL 1'' switch to prevent more product from entering product blender tank. ''OFF 1'',
''OFF 2'', and ''SYRUP 2'' fault messages will continue to be displayed.
7. Repeat steps 3 and 4 preceding to check product sample for BRIX.
8. Repeat steps 5 through 7 preceding until proper BRIX adjustment is achieved.
9. Repeat steps 1 through 8 preceding to adjust BRIX of dispensed product on No. 2 system. After
completing BRIX adjustment on No. 2 system, only the ''OFF 1'' and ''OFF 2'' fault messages should
continue to be displayed.
NOTE: Syrup systems may be sanitized at this time as instructed.

FILLING FREEZE CYLINDERS WITH PRODUCT

1. Open product shutoff valves, located in lines leading from product blender tanks to freeze cylinders.
2. Press ''AUTO BLEND 1'' and ''AUTO BLEND 2'' switches to begin filling freeze cylinders. Open freeze
cylinders faceplates relief valves to bleed air from cylinders while filling with product, then close valves. Do
not relieve freeze cylinder pressure too fast or product will foam excessively in cylinder and lose
carbonation.
