The Model 6321L is a freezer that dispenses frozen carbonated alcoholic beverages (see photo on front cover). The freezer has two major components, the freezer sections (dispense head) and the product feed system (lower cabinet area). The freezer consists of a freezing cylinder with a rotating internal auger (dasher) that is belt driven by an elect[...]

The freezer is equipped with an automatic defrost system to allow the frozen product to melt back to a liquid. This eliminates any large ice crystal formation or poor product consistency that may develop. This automatic timer can be pre-programmed to occur at desired times of the day. The defrost cycle takes four hours to complete and should be pro[...]

Periodic Inspection Freezer Assembly and Installation 1) Check the CO 2 tank pressure gauge on the cylinder regulator assembly. Replace if tank pressure drops below red line. 2) Make sure the unit contains a sufficient supply of syrup and alcohol. 3) Check to see that there is sufficient air space on both sides of the unit. Proper air circulation i[...]

1) The drip tray is mounted on two screws that are located on the lower front of the freezer cabinet. 2) Place the key hole slot of the drip tray support bracket W0471022 on to these screws and tighten the screws. 3) Angle the back of the drip tray surround bracket into the drip tray support bracket W0471022 and lower bracket to lock it into place.[...]

NOTE: CO 2 regulators are pre-set at the factory. Check for accuracy. 1) Adjust the CO 2 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[...]

Adding Product Connecting Syrup Supply 1) Open new bag-in-box as instructed on box. 2) Connect red QCD syrup connector to new bag-in-box. 3) Repeat for second bag-in-box. NOTE: Make sure that the BIB lines run behind the bottle rack line so the bottle rack can be slid open easily. Crathco Beverage Freezers Page 7 1) Remove bottle cap. 2) Slide a wh[...]

6) If the volume is not 3.7 oz. (110 ml), consult the Troubleshooting Guide in this manual. Note: Due to the thick viscosity of the syrup, it may be necessary to purge the syrup line to obtain an accurate flow rate reading. Purge the syrup line by first closing the syrup valve, opening the water valve and then momentarily turning on the test switch[...]

NOTE: Before cleaning, all product should be drained from the freezing cylinder, pres - sure vented, and either the valves set closed or product removed from the machine. 1) Disassemble the dispensing valve by first removing the dispensing valve pin (Figure 12) 2) Push up on the dispensing valve plunger and pull out the dispensing handle. The plung[...]

NOTE: The following product consistency (thickness) control adjustment procedure requires removal of the right side panel. It is suggested that a qualified service technician make this adjustment because side panel removal exposes hazardous moving parts. Warning: Do not attempt freezer adjustments until electrical power has been disconnected. It ma[...]

BRIX Correct BRIX effects product flavor and freezing characteristics. Frozen product with low BRIX may have a weak fla - vor, larger ice crystals, and a tendency to dispense slowly. Product with high BRIX has an overly strong flavor, increased portion cost and results in lower freezer output capacity. Alcohol Content High alcohol content may preve[...]

Operating Freezer Unit Operation 1) Check that a "Mix Out" light is not illuminated. This indicates the freezer has an adequate amount of syrup, CO 2, 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 cabine[...]

Service and Maintenance Servicing Dispensing Valves, O-Rings, and Freeze Cylinder Drive Shaft/Seal Assemblies NOTE: Dispensing valve "O" Rings should be replaced every 120 days to correspond with quarterly preventative maintenance visits. The best technique for removing an "O" Ring is to first wipe off all of the lubricant using[...]

Drive Belt Adjustment CAUTION: Unplug the machine before performing any adjustments. Check the belt tension quarterly. Proper belt tension is ½" deflection measured mid way between the drive and driven pulleys. If the deflection is more than ½" adjust the motor height to achieve proper tension using the following procedure: 1) Unplug th[...]
