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.

PRODUCT CARBONATION ADJUSTMENT

(see Figures 2 and 8)
Carbonation of dispensed product can also be varied to suit consumer preference by adjusting Unit carbonator
secondary CO regulator as follows:

IMPORTANT: Carbonator tank secondary CO
product blender tanks secondary CO
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
enough will cause decreased flow of carbonated water into blender tanks, which will increase BRIX of
dispensed product.
1. Remove Unit lower front access panel as instructed for access to carbonator secondary CO
with 100-psi gage.
2. Observe pressure setting on carbonator secondary CO
3. To lower CO pressure, loosen regulator adjusting screw lock nut. Turn adjusting screw to the left (counter-
2
clockwise) until pressure gage reads 15-psi below desired reading, then turn screw to the right (clockwise)
until gage reads desired pressure. DO NOT SET CO
ER THAN PRODUCT BLENDER TANKS CO
IMPORTANT NOTE). Tighten adjusting screw lock nut after each adjustment.
4. Observe pressure setting on carbonator secondary CO
5. To raise CO pressure, turn regulator adjusting screw to the right (clockwise) until gage reads desired pres-

sure. DO NOT SET PRESSURE HIGHER THAN 60-PSI. Make sure primary CO
der is set at 80 to 100-psi. Tighten adjusting screw lock nut after each adjustment.
6. Install lower front access panel on Unit.
