Operating Freezer

Unit Operation

1)Check that a "Mix Out" light is not illuminated. This indicates the freezer has an adequate amount of syrup, CO2, alcohol and water (only one light will be ON at a time). Check machine after each product is filled.

2)Insure that the "ON/OFF" switch in the lower back compartment of the cabinet is in the "ON" position.

3)Insure that the "TEST/OFF/RUN" switch in the lower back compartment of the cabinet is in the "RUN" position.

4)Insure that the "ON/OFF/CLEAN" switch on the front of the freezer is in the "ON" position.

5)Allow the freezer sufficient time to reach desired product consistency (compressor will shut off).

6)Slowly open the dispensing valve to dispense frozen product.

7)If frozen product consistency is not correct, readjust following the instructions found in the PRODUCT CONSISTENCY section of this manual.

Replenishing Syrup Supply

A vacuum transfer valve will automatically switch from an empty BIB container to a full one. Check BIB containers on a regular basis and replace empty BIB following the procedure in the CONNECTING SYRUP SUPPLY section of this manual.

Replenishing CO2 Supply

8)Place new CO2 cylinder in the place of the used CO2 cylinder.

9)Make sure that the CO2 regulator assembly coupling nut gasket is undamaged.

10)Attach the regulator hose on the new CO2 cylinder.

CAUTION: The CO2 lines need to be pressurized slowly to insure they are not damaged. Open the tank shut off

valve slowly until it is fully open. NOTE: Opening the valve all the way prevents leakage around the valve shaft.

Replenishing Alcohol Supply

1)Remove empty alcohol bottles.

2)Remove white tubular adapters from bottles.

3)Remove caps from new bottles and slide white plastic adapter over the neck until the bottle seats itself against the shoulder of the adapter.

4)Bend the nozzle of the white plastic adapter over with your forefinger to stop liquor flow.

5)Insert the nozzle of the white plastic adapter into the reservoir port and allow adapter to drop into the reservoir opening.

6)Stand inverted bottle upright.

7)Loosen the thumbscrew on the hold-down bracket and slide the hold-down bracket until it is centered on the bottom of the bottle.

8)Push down on bracket until it firmly holds the bottle in place…tighten the knob.

9)Repeat for each bottle

Note: If you are using partially empty bottles place the emptiest bottle at the end of the reservoir farthest from the reservoir outlet tubing. This will allow the partially filled bottle to be emptied first.
