Adjusting Co2 Regulators - Cornelius FCB 3 H.P. POST-MIX DISPENSER Installation & Service Manual

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
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.
