ADJUSTING CARBONATED WATER FLOW RATE
The back carbonated water flow regulators (see applicable Figure 2 or 3 and 7), which control carbonated
water flow rate into the product blender tanks, are factory adjusted for a flow rate of 1.3 ± 0.05 ounces per
second and normally do not require adjustment. However, if adjustment is necessary, proceed as follows:
1. Press applicable ‘‘OFF 1’’ or ‘‘OFF 2’’ switch to prevent more product from entering the applicable product
blender tank.
2. Disconnect Unit syrup inlet line from the applicable soft drink tank.
3. Remove applicable side panel from the Unit as instructed for access to the applicable carbonated water
flow regulator, product shutoff valve, and product sample valve.
4. Close applicable product shutoff valve to prevent more product from entering the freeze cylinder.
5. Place container under applicable product sample valve. Open the valve and allow all product to be purged
from the product blender tank, then close the valve.
6. Remove the lower front access panel as instructed for access to the secondary CO
2
regulators.
7. Note pressure setting on the applicable secondary CO
2
regulator with 60 psi gage for the applicable
product blender tank. Turn regulator adjusting screw out (counterclockwise) until gage reads 0-psi. Pull up
on the applicable product blender tank relief valve to release CO
2
pressure from the tank.
8. Disconnect carbonated water line from the outlet side of the applicable carbonated water flow regulator.
9. Connect line, long enough to reach to the outside of the Unit, to the water flow regulator outlet, then route
the line to the outside of the Unit.
10. Place end of the carbonated water line, routed to the outside of the Unit, in the container.
11. Press applicable ‘‘AUTO BLEND 1’’ or ‘‘AUTO BLEND 2’’ switch to activate the electrically operated
carbonated water solenoid.
12. When a steady stream of water is flowing from the added length of line, catch carbonated water in a
container graduated in ounces for exactly 10 seconds. Press applicable ‘‘FILL 1’’ or ‘‘FILL 2’’ switch to
deactivate the carbonated water solenoid. In 10 seconds, 12 to 14 ounces of water should have been
dispensed.
13. If adjustment is necessary, turn the regulator adjusting screw to the left (counterclockwise) 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
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.
