Filling CO2 Lines

CAUTION: CO2 lines should be filled slowly to prevent the possibility of damaging components. Open tank shut off valve slowly until it is completely open.

NOTE: Open valve all the way to prevent leakage around the valve shaft.

Adjusting CO2 Regulators

NOTE: CO2 regulators are pre-set at the factory. Check for accuracy.

1)Adjust the CO2 regulator that drives the bag-in-box syrup pump and alcohol pump to 60 psi. Turning regulator adjustment clockwise raises the pressure. Tighten locknut at this setting. (Figure 7)

CAUTION: The use of excessive pressure (above 75 psi) will result in pump seizure.

2)Adjust the CO2 regulator, connected to the carbonator, to

90 psi. NOTE: Do not exceed 120 psig, the carbonator pressure relief setting. Turning regulator adjustment clockwise raises the pressure. Tighten locknut at this setting.

Activating Water Source Line Connection

Open the water line manual shut-off valve in the base cabinet of the 6321L and check for water leaks.

Sanitizing and Starting Unit

Sanitizing

1)Prepare a minimum of 2 gallons (7.6 liters) of sanitizing solution (Divorsol CX or equivalent).

NOTE: Add 5 ounces (150 ml) of Divorsol CX to 2 gallons (7.6 liters) of 120° Fahrenheit (50° Centigrade) water to achieve a concentration of 500 parts per million.

2)Disassemble the freezer following steps 1 through 8 in the Cleaning Section.

NOTE: For initial start-up, be sure to clean and sanitize the freezer before adding product.

3)After disassembly, thoroughly scour each part of the freezer in a warm mild detergent solution including the inside of the freezing cylinder. Dip or wipe each part in sanitizing solution and allow to air dry on clean paper toweling. DO NOT WASH COMPONENTS IN A DISHWASHER.

4)Rinse each part with clean water.

5)Reassemble components following the instructions in the Cleaning section of this manual.

6)Pour 1.5 quarts of sanitizing solution into both the front and back alcohol bottle rack.

7)Connect a red QCD cleaning fitting to one of the BIB connectors in the lower back cabinet and immerse the BIB connector into the remaining solution.

NOTE: If a QCD cleaning fitting is not available, cut the plastic outlet fitting out of an empty BIB container.

8)Sanitize system by opening all three of the manual shut-off valves in the back of the lower cabinet (syrup, alcohol and carbonated water).

9)Turn the freezer switch to "CLEAN".

10)Turn the control switch in the back of the base cabinet to "AUTO".

11)Allow the freeze cylinder to fill half way and run for 5 minutes.

12)Turn the freezer switch from "CLEAN" to "OFF".

13)Open the pressure relief valve located on the freezer dispensing valve to relieve all of the pressure in the freeze cylinder.

14)Remove the QCD cleaning fitting from the first BIB line and place

it on the other BIB connection. Place second line in remaining solution.

15) Pull or push transfer valve to opposite setting.(Figure 8)

16)Repeat steps 9-12.

17)Remove BIB connector from container of sanitizing solution.

18)Purge sanitizer from product lines and barrel.
