ADJUSTING BRIX (WATER-TO-SYRUP) ‘‘RATIO’’ OF DISPENSED PRODUCT
(see Figures 2 and 6)
1. Remove Unit front lower access panel as instructed for access to product blender tanks secondary CO
2
regulators and product sample valves.
2. Check product blender tanks secondary CO
2
regulators, with 60-psi gages, for proper pressure settings
which is set at 30-psi for best textured dispensed product. If adjustment is necessary, adjust as instructed.
3. Remove both Unit side panels as instructed for access to product shutoff valves located close to product
blender tanks.
4. Close product shutoff valve in line between applicable product blender tank and associated freeze cylinder
BRIX adjustment will be performed on.
5. Press applicable ‘‘FILL 1’’ or ‘‘FILL 2’’ switch to prevent more product from filling product blender tank.
6. Open applicable product blender tank product sample valve and take sample (approximately 6-ounces) of
product in cup.
NOTE: Temperature compensated hand-type refractometers (P/N 511004000) are available from the Cornelius
Company.
7. Check product BRIX with a temperature compensated hand-type refractometer. BRIX should read 13 ± 1.
If BRIX is not within tolerance, adjust applicable white syrup flow regulator as follows:
A. Loosen jamb nut on applicable syrup flow regulator.
B. Turn 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.
C. Tighten jamb nut on syrup flow regulator, then lightly tap regulator to register adjustment.
8. Place container under applicable product sample valve. Open valve to purge product out of product blender
tank, line, and valve, then close valve.
9. Press applicable ‘‘AUTO BLEND 1‘’ or ‘‘AUTO BLEND 2’’ switch to fill product blender tank 1/4-full of new
batch of product. When product blender tank is 1/4-full of product, press applicable ‘‘FILL 1’’ or ‘‘FILL 2’’
switch to prevent more product from entering product blender tank.
10. Repeat steps 6 and 7 preceding to check product sample for BRIX.
11. Repeat steps 7 through 10 preceding until proper BRIX adjustment is achieved.
12. Open product shutoff valve in line between product blender tank and freeze cylinder.
13. Press applicable ‘‘AUTO BLEND 1’’ or ‘‘AUTO BLEND 2’’ switch.
14. Install Unit side panels and front lower access panel by reversing removal procedures.
PRODUCT CARBONATION ADJUSTMENT
(see Figures 2 and 6)
Carbonation of dispensed product can also be varied to suit consumer preference by adjusting Unit carbonator
secondary CO
2
regulator as follows:
IMPORTANT: Carbonator tank secondary CO
2
regulator must be adjusted 25-psi higher or more above
product blender tanks secondary CO
2
regulators pressure settings. Carbonated water and syrup
pressures must be able to overcome and vent product blender tanks head pressures while tanks are
filling with carbonated water and syrup. Carbonator tank secondary CO
2
regulator not adjusted high
enough will cause decreased flow of carbonated water into blender tanks which will increase BRIX of
dispensed product.
