Adjusting Brix (Water-To-Syrup) ''Ratio'' Of Dispensed Product - Cornelius R-404A REFRIGERANT Service Manual

Carbonator Secondary CO
(see Figure 2 and 6)
1. Remove the Unit lower front access panel as instructed for access to the carbonator(s) secondary CO
regulator(s).
IMPORTANT: The carbonator tank secondary CO
above the product blender tanks secondary CO
and syrup pressures must be able to overcome and vent the product blender tanks head pressures
while the tanks are filling with carbonated water and syrup. Carbonator tank secondary CO
not adjusted high enough will cause a decreased flow of carbonated water into the blender tanks,
which will increase brix of the dispensed product.
2. Adjust carbonator(s) secondary CO
screw(s) to the right (clockwise) until gauge(s) reads 50 to 60-psig.
3. Install the lower front access panel by reversing the removal procedure.

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

(see Figures 2 and 6)
1. Remove Unit lower front access panel as instructed for access to product blender tanks secondary CO
regulators and product sample valves.
2. Check product blender tanks secondary CO
which is set at 25 to 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 Cor-
nelius Company.
7. Observe pressure setting on carbonator secondary CO
8. 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.
9. Repeat steps 6 and 7 preceding to check product sample for brix.
10. Repeat steps 7 through 10 preceding until proper brix adjustment is achieved.
11. Open product shutoff valve in line between product blender tank and freeze cylinder.
12. Press applicable ''AUTO BLEND 1'' or ''AUTO BLEND 2'' switch.
13. Install Unit side panels and lower front access panel by reversing removal procedures.
