Cornelius R-404A REFRIGERANT service manual Adjusting CO2 Regulators

11.Press applicable ‘‘AUTO BLEND 1’’ or ‘‘AUTO BLEND 2’’ switch to activate the electrically operated car- bonated water solenoid.

12.When a steady stream of water is flowing from the added length of line, catch carbonated water in a con- tainer graduated in ounces for exactly 10 seconds. Press applicable ‘‘FILL 1’’ or ‘‘FILL 2’’ switch to deacti- vate the carbonated water solenoid. In 10 seconds, 12 to 14-ounces of water should have been dispensed.

13.If adjustment is necessary, turn the carbonated water flow regulator adjusting screw to the left (counter- clockwise) to reduce carbonated water flow rate or turn the screw to the right (clockwise) to increase the flow rate.

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 car- bonated water line, disconnected from the carbonated water flow regulator in step 8 preceding, to the regu- lator outlet.

16.Turn the product blender tanks CO2 regulator, with 60-psi gauge, adjusting screw in (clockwise) until gauge 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.

21.Close front access door, then use a flat blade screwdriver to turn lock clockwise to lock the door.

22.Install the lower front access panel by reversing the removal procedure.

ADJUSTING CO2 REGULATORS

NOTE: To readjust CO2 regulator to a lower setting, loosen the adjusting screw lock nut, then turn the screw to the left (counterclockwise) until the pressure gauge reads 5-psi lower than the new setting will be. Turn the adjusting screw to the right (clockwise) until the gauge registers a new setting, then tight- en the lock nut.

Primary CO2 Regulator.

(see Figure 2)

Adjust the primary CO2 regulator by turning the regulator adjusting screw to the right (clockwise) until the regu- lator pressure reads 80 to 100-psig.

Product Blender Tanks Secondary CO2 Regulators.

(see Figures 2 and 6)

1.Remove the Unit lower front access panel as instructed for access to the product blender tanks secondary CO2 regulators.

2.Adjust the product blender tanks secondary CO2 regulators, with 60-psi gauges, by turning their regulator adjusting screws to the right (clockwise) until their gauges read 25 to 30-psig for best textured product.

3.Install the lower front access panel by reversing the removal procedure.
