14. Repeat steps 11 through 13 until the desired carbonated water flow rate is achieved.
15. Remove added length of line from the outlet side of the carbonated water flow regulator. Connect the
carbonated water line, disconnected from the carbonated water flow regulator in step 8 preceding, to the
regulator outlet.
16. Turn the product blender tanks CO
2
regulator, with 60-psi gage, adjusting screw in (clockwise) until gage
registers pressure noted in step 7 preceding.
17. Pull relief valve on the applicable product blender tank to purge air from the tank, then close the valve.
18. Connect Unit syrup inlet line to the soft drink tank.
19. Press the applicable ‘‘AUTO BLEND 1’’ or ‘‘AUTO BLEND 2’’ switch to fill the product blender tank with
product.
20. Open the product shutoff valve that was closed in step 4 preceding.
21. Install the side panel and the lower front access panel by reversing removal procedure.
ADJUSTING CO
2
REGULATORS
NOTE: To readjust CO
2
regulator to a lower setting, loosen the adjusting screw lock nut, then turn the
screw to the left (counterclockwise) until the pressure gage reads 5-psi lower than the new setting will
be. Turn the adjusting screw to the right (clockwise) until the gage registers new setting, then tighten
the lock nut.
Primary CO
2
Regulator. (see Figure 2)
Adjust the primary CO
2
regulator by turning the regulator adjusting screw to the right (clockwise) until the
regulator pressure reads 80 to 100-psig.
Product Blender Tanks Secondary CO
2
Regulators. (see Figure 2)
1. Remove the Unit lower front stainless steel access panel as instructed for access to the product blender
tanks secondary CO
2
regulators.
2. Adjust the product blender tanks secondary CO
2
regulators, with 60-psi gages, by turning their regulator
adjusting screws to the right (clockwise) until their gages read 25 to 30-psig.
3. Install the lower front stainless steel access panel by reversing the removal procedure.
Carbonated Water Tank Secondary CO
2
Regulators. (see Figure 2)
1. Remove the Unit lower front access panel as instructed for access to the carbonated water tanks
secondary CO
2
regulators.
IMPORTANT: The carbonated water tanks secondary CO
2
regulators must be adjusted 25-psi higher or
more above the product blender tanks secondary CO
2
regulators pressure settings. The Carbonated
water 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. Carbonated water tanks
secondary CO
2
regulators not adjusted high enough will cause a decreased flow of carbonated water
into the blender tanks which will increase the brix of the dispensed product.
2. Adjust carbonated water tanks secondary CO
2
regulators, with 100-psi gages, by turning regulators
adjusting screws to the right (clockwise) until gages reads 50 to 60-psig.
3. Install the lower front access panel by reversing the removal procedure.
