ACTIVATING SYRUP SOURCE SYSTEM
IMPORTANT: The product shutoff valves, located in the product lines leading from the product blender
tanks to the freeze cylinders (see applicable Figure 4 or 5), must be closed at this time. Closing the
valves prevents product from filling the freeze cylinders while checking BRIX of the product in the
product blender tanks.
1. Close product shutoff valves, located in lines leading from the product blender tanks to the freeze cylinders,
to prevent product from entering the freeze cylinders.
2. Press “BLEND ON/OFF” control panel switches to display “BLNDOFF 1” and “BLNDOFF 2” on the
message display.
3. Activate the syrup source system (syrup tanks or bag-in-box system) to begin providing syrup to the FCB
Dispenser. CO

regulator must be set at no less then
80-psi for the bag-in-box syrup pumps in a bag-in-box syrup system or 80 to 100-psi for the syrup tanks in
a syrup tanks syrup system. The “OFF 1”, “OFF 2”, “SYRUP 1”, and the “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 systems.
NOTE: The adjustable carbonated water flow regulators (see applicable Figure 4 or 5 and16) 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, refer to SERVICE AND MAINTENANCE section of this manual for adjustment
procedure.
1. Press ‘‘SYRUP PRIME’’ switch to fill No. 1 syrup system sold-out float. ‘‘SYRUP 1’’ fault message will go
out. The ‘‘OFF 1’’, ‘‘OFF 2’’, “BLNDOFF 1”, “BLNDOFF 2” and the “SYRUP 2” fault messages will
continue to be displayed.
2. Press ‘‘BLEND ON/OFF’’ switch to fill No. 1 system product blender tank with product. ‘‘BLND 1’’ fault
message will go out when ‘‘BLEND ON/OFF’’ switch is pressed. When product blender tank is full, press
the ‘‘BLEND ON/OFF’’ switch again to prevent more product from entering the blender 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 and take a 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. The BRIX should read
13 ± 1. If BRIX is not within this tolerance, adjust the syrup flow regulator for No. 1 syrup system as
follows:
Turn the syrup flow 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 the valve to purge product out of the product
blender tank, line, and valve, then close the valve.
6. Press ‘‘BLEND ON/OFF’’ switch to run new batch of product into the product blender tank. When the
product blender tank is full, press the ‘‘BLEND ON/OFF’’ switch again to prevent more product from
entering the 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.
