The primary CO2 regulator assembly in turn delivers CO2 gas to adjustable secondary CO2 regulators inside the Unit and also to two soft drink tanks. CO2 is delivered from the adjustable secondary CO2 regulators to the carbonator tank and also to product-blender tanks inside the Unit. CO2 gas pressure pushes syrup out of the soft drink tanks through the syrup sold-out switches, through adjustable syrup flow regulators, through electrically operated syrup solenoid valves, and on to the product blender tanks. At the same time, plain water passes through the water pressure regulator and is pumped into the carbonated water tank by the water pump and is carbonated by CO2 gas pressure also entering the tank. Carbonated water is pushed by CO2 gas pressure from the carbonated water tank, through adjustable carbonated water flow regulators, through electrically operated carbonated water solenoid valves, and on to the product blender tanks. Carbonated water and syrup enter the tanks properly proportioned (blended) for desired BRIX of dispensed product by adjustment of the syrup flow regulators. From product blender tanks, product is pushed by the CO2 gas into the freeze cylinders. The beater in each freeze cylinder is driven by an electric motor. Scraper blades, attached to the beaters, scrape product from the cylinder walls as product enters the freeze cylinders and is frozen. 312028000 2 Transparent faceplate, attached to the front of each freeze cylinder, includes a self-closing dispensing valve and a spring-loaded relief valve that protects freeze cylinder from accidental over pressure. The relief valve is also used to bleed CO2 gas pressure from the freeze cylinder to atmosphere when filling the cylinder with product. Electronic sensing on each freeze cylinder motor provides a means of adjusting viscosity (consistency) of the dispensed product to suit customer preference. FIGURE 1. FCB OVERCOUNTER POST-MIX DISPENSER DEFROST SYSTEMS The Unit is equipped with both manual and automatic hot-gas defrost systems. The automatic defrost system may be programmed into the Unit to occur up to nine different times a day with a minimum of two hours between defrost time settings or the system may be completely turned off. MANUAL DEFROST SYSTEM The Manual hot-gas defrost system may be activated at any time by pressing the ‘‘DEFROST’’ switch on front of the Unit. Refrigeration compressor will operate for a short time, then both freeze cylinders will go into defrost for approximately 60 seconds. At the end of the manual defrost cycle, the Unit will return to normal operation. Manual defrost may be cancelled at any time by pressing the ‘‘CANCEL DEFROST’’ switch. AUTOMATIC DEFROST SYSTEM The automatic hot-gas defrost system may be programmed into the Unit to occur up to nine different times a day with a minimum of two hours between defrost settings. At the start of each automatic defrost cycle, refrigeration compressor will operate for 30 seconds to pump freon out of the freeze cylinders evaporator coils. After freon has been pumped out of the freeze cylinders evaporator coils, No. 1 freeze cylinders only will go into defrost cycle for approximately 7 minutes, then will return to normal operation. This ends the automatic defrost cycle of the No. 1 freeze cylinder. No. 2 freeze cylinder will defrost 30 minutes after the start of No. 1 freeze cylinder. The next automatic defrost cycle will occur according to the time programmed into the Unit. Automatic defrost may be cancelled at any time by pressing the ‘‘CANCEL DEFROST’’ switch. 3 312028000 ‘‘SLEEP’’ (SLEEP TIME) ‘‘SLEEP’’ (SLEEP TIME) may be programmed into Unit to allow Unit to go into sleep time (Unit shut down, freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, refrigeration compressor will operate for 30 seconds to pump freon out of freeze cylinders evaporator coils, then No. 1 freeze cylinder will go into defrost for 60 seconds. After No. 1 freeze cylinder has defrosted, No. 2 freeze cylinder will go into defrost for 60 seconds. At the end of No. 2 freeze cylinder defrost, Unit will shut down and go into sleep time. ‘‘WAKE UP’’ (WAKE UP TIME) ‘‘WAKE UP’’ (WAKE UP TIME) may be programmed into the Unit to allow Unit to resume normal operation at a desired time. When programmed wake up time is reached, an alarm will sound for a short duration, then Unit will resume normal operation. NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or separately. 312028000 4 FIGURE 2.

Due to a redesign of the foam pack in the models documented in this manual, elevating the front of the Dispenser is no longer required. The Dispenser must be leveled at time of placing in operating location. 1. Disconnect electrical power from Unit at the electrical power source disconnect switch. IMPORTANT: When installing Unit in it’s operating position, do not allow obstructions to block sides, top, and front of the Unit which will block off cooling air intake to the inside of the Unit. Air flow through the Unit must be present to provide adequate cooling for the refrigeration system. Refer to SELECTING LOCATION for sides, top, and front clearances to be observed when placing Unit in operating position. 2. Referring to the preceding NOTE, very carefully, place the Unit in operating location. 3. Make sure the Unit is sitting level. The Unit may be leveled by using a carpenter’s level and adjusting the four leveling legs installed on the Unit during installation. 4. Restore Unit to operation by connecting electrical power at the electrical power source disconnect switch. ADJUSTING BEATER MOTOR CURRENT (EITHER SIDE) Adjusting beater motor current (either side) procedure is very important and must be performed as instructed. Be sure you fully understand the instructions before performing the current adjustments or doing any preventative maintenance current readings check. Any current adjustments or preventative maintenance current readings check on the beater motor current (either side) must be performed with both freeze cylinders fully defrosted. A partially defrosted freeze cylinder will cause false current readings to be displayed on the message display. Adjust beater motor current (either side) as follows: 1. Using a flat blade screwdriver, turn lock counterclockwise to unlock the front access door (see Figure 5), then open the door. 2. Remove four screws securing the upper electrical control box cover (control box located on back of the front access door). Remove cover for access to the master circuit board (see Figure 4). 3. Place No. 4 ‘‘BEATER MOTOR CURRENT READOUT’’ switch on DIP SWITCH assembly on master circuit board (see Figure 4) in ‘‘ON’’ position.

FREEZE CYLINDERS MANUAL OR AUTOMATIC DEFROST SYSTEMS The Unit is equipped with both manual and automatic hot-gas defrost systems. The automatic defrost system may be programmed into the Unit to occur up to nine different times a day with a minimum of two hours between defrost time settings or the system may be completely turned off. MANUAL DEFROST SYSTEM The manual hot-gas defrost system may be activated at any time by pressing ‘‘DEFROST’’ switch on front of the Unit. Refrigeration compressor will operate for a short time, then both freeze cylinders will go into defrost and defrost for approximately 60-seconds. At end of manual defrost cycle, Unit will return to normal operation. Manual defrost may be cancelled at any time by pressing ‘‘CANCEL DEFROST’’ switch. AUTOMATIC DEFROST SYSTEM The automatic hot-gas defrost system may be programmed into the Unit to occur up to nine different times a day with a minimum of two hours between defrost settings. At start of each automatic defrost cycle, refrigeration compressor will operate for 30 seconds to pump freon out of freeze cylinders evaporator coils. After freon has been pumped out of freeze cylinders evaporator coils, No. 1 freeze cylinder only will go into defrost for approximately 7 minutes and then will return to normal operation. This ends automatic defrost cycle of No. 1 freeze cylinder. No. 2 freeze cylinder will defrost 30 minutes after the start of No. 1 freeze cylinder. The next automatic defrost cycle will occur according to time programmed into the Unit. 29 312028000 ‘‘SLEEP’’ (SLEEP TIME) OPERATION ‘‘SLEEP’’ (SLEEP TIME) may be programmed into Unit to allow Unit to go into sleep time (Unit shut down, freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, refrigeration compressor will operate for 30 seconds to pump freon out of freeze cylinders evaporator coils. Then No. 1 freeze cylinder will go into defrost for 60-seconds. After No.1 freeze cylinder has defrosted, No. 2 freeze cylinder will go into defrost for 60-seconds. At end of No. 2 freeze cylinder defrost, Unit will shut down and go into sleep time. ‘‘WAKE UP’’ (WAKE UP TIME) ‘‘WAKE UP’’ (WAKE UP TIME) may be programmed into the Unit to allow Unit to resume normal operation at a desired time. When programmed wake up time is reached, an alarm will sound for a short duration, then Unit will resume normal operation. NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or separately. FACEPLATE RELIEF VALVES The faceplate relief valves (see Figure 5), located in each freeze cylinder faceplate, are spring-loaded valves that protect freeze cylinders from accidental over-pressure. The relief valve is also used to manually bleed CO2 gas from freeze cylinder to atmosphere during filling with product and if gas pockets form in cylinder during operation. PRODUCT SAMPLE VALVES The two product sample valves are located behind the lower front access panel (see Figure 2 and Figure 6) and are manually operated lever-type ball valves used to check product BRIX. Turn valve lever to line up with attached line to open valve and at 90° angle with line to close valve. PRODUCT SHUTOFF VALVES The two product shutoff valves, located in lines leading from the product blender tanks to the freeze cylinders (see Figure 2 and 6), are manually operated lever-type ball valves and are used to prevent product from entering and filling freeze cylinders while adjusting BRIX of dispensed product. Shutoff valves may also be used to shut off product to individual freeze cylinder for service and maintenance without disrupting operation of other freeze cylinders. PRIMARY CO2 REGULATOR The primary CO2 regulator (see Figure 2) controls CO2 pressure to the soft drink tanks and the Unit secondary CO2 regulators located behind the lower front access panel. If necessary to adjust the primary CO2 regulator, adjust as instructed in the SERVICE AND MAINTENANCE section. SECONDARY CO2 REGULATORS The secondary CO2 regulators, located behind the lower front access panel (see Figure 2 and 6), control CO2 pressure to the carbonator and the product blender tanks. If necessary to adjust the secondary CO2 regulators, adjust as instructed in the SERVICE AND MAINTENANCE section. CARBONATED WATER FLOW REGULATORS The adjustable carbonated water flow regulators, (see Figure 2 and 12) located behind the front access panel, control carbonated water flow rate to the product blender tanks. The water flow regulators are factory adjusted at 1.3 0.05 oz/sec and should not normally require adjustment. If adjustment is necessary, adjust as instructed in the SERVICE AND MAINTENANCE section. 312028000 30 SYRUP FLOW REGULATORS The syrup flow regulators located behind the front access door (see Figure 2 and Figure 12), are adjustable regulators that control syrup flow rate to the product blender tanks for desired BRIX of dispensed product. Adjust syrup flow regulators for desired BRIX as instructed in the SERVICE AND MAINTENANCE section. DISPENSING VALVES Self-closing dispensing valves (see Figure 5)), located on faceplates on front of Unit, are operated one at a time or simultaneously to deliver product to the customer. DISPENSED PRODUCT CONDITIONS ‘‘OVERRUN’’, AS APPLIED TO FROZEN CARBONATED BEVERAGES Overrun Defined. Overrun is product expansion that takes place in the frozen carbonated drink. It is caused primarily by CO2 gas breakout and secondary by freezing. Overrun is a Variable. The percentage or degree of overrun depends on a number of factors. The specific syrup, BRIX, low dispensing volume, carbonation level in liquid product, and freezing, all affect overrun. After these factors have been considered, desired viscosity (product consistency) adjustment may be made on the Unit. The viscosity adjustment adjusts product texture from very wet to light. Specific Product Ingredients Affect Overrun. Each syrup has its own specific formulation of makeup. Baume, an important ingredient factor, may fall within an extremely wide range. Fruit flavors contain citric acids that colas do not. Colas also differ in ingredients from one brand to another. Each product formulation has its own peculiarities regarding the way the product will absorb carbonation and the way it will release carbonation. BRIX Affects Overrun. Sugar in carbonated drinks is like anti-freeze in water. The higher the BRIX in a product, the greater resistance the product has to freezing. Conversely, in products with lower BRIX, freezing takes place at higher temperatures than for high-BRIX products. Thus, BRIX affects overrun because the amount of sugar in a drink has a direct bearing on the product’s freezing characteristics. DRAWING 1 DRAWING 2 DRAWING 3 Low Dispensing Volume Affects Overrun. When Unit sits idle for a period of time and no drinks are dispensed, CO2 gas in the system takes a ‘‘set’’. When first few drinks are drawn off after an idle period, CO2 gas has less tendency to break out as drink is dispensed. The result is these casual drinks have less overrun than drinks dispensed during peakĆuse periods. 31 312028000 Carbonation Level in Liquid Product Affects Overrun. The higher the specific carbonation level in a given product, the greater the potential for carbonation breakout in frozen carbonated form of that drink. For example, drinks with 3.0 volume of carbonation will have more gas breakout in frozen carbonated form, and more overrun, than will drinks that contain 2.0 volumes of CO2 gas. Freezing Affects Overrun. Freezing causes approximately a 10 percent expansion in dispensed frozen carbonated drinks. The degree of freezing is limited because the finished drink is intended to be sipped through a straw. This is not possible if the product is too ‘‘solid’’. OPERATING CHARACTERISTICS The product viscosity (product consistency) can be varied by adjustment and secondary CO2 regulator setting from a high overrun light drink to a wet, heavy drink. The length of freezing cycle and amount of CO2 present in product combine to create the drink dispensed. The dispensed product will have a normal variance due to the following conditions: 1. If some time has elapsed since last drink was drawn from particular freeze cylinder and compressor has not cycled on, the drink dispensed will have a tendency to be wetter, have slightly less overrun than normal for the setting, and will not mound up as high. See Drawing 1. NOTE: A cylinder freeze-up may be expected under casual draw conditions if an attempt is made to eliminate drink described above by adjusting viscosity. 2. If product is drawn from freeze cylinder quite regularly, its viscosity (product consistency) will be maintained at whatever viscosity adjustment was made within the normal variance of the compressor off and on cycle. See Drawing 2. 3. If product is drawn continuously from freeze cylinder and rate is approaching capacity of the dispensing unit, overrun of drink will increase just prior to point capacity is exceeded, and drink dispensed will turn slightly wetter. See Drawing 3. OPERATING UNIT NOTE: The No. 1 freeze cylinder (see Figure 5) is the left-hand cylinder facing the front of the Unit. No. 2 freeze cylinder is to the right of No. 1 freeze cylinder. 1. Make sure ‘‘H2O OUT’’ fault message is not displayed on message display. This indicates no water supply to Unit. 2. Make sure ‘‘CO2 OUT’’ fault message is not displayed on message display. This indicates no CO2 gas supply to Unit. 3. Make sure ‘‘SYRUP 1’’ or ‘‘SYRUP 2’’ fault messages are not displayed on message display. This indicates no syrup supply to Unit. 4.

REPLENISHING SYRUP SUPPLY IMPORTANT: The following CO2 and liquid disconnects disconnecting and connecting procedure for soft drink tank replacement or filling soft drink tank in place must be performed in order as follows: 312028000 32 1. To disconnect soft drink tank from Unit syrup system. A. Disconnect liquid disconnect from soft drink tank. NOTE - Disconnecting liquid quick disconnect from soft drink tank first prevents syrup from backflowing through Unit syrup flow regulator, which may alter regulator adjustment. B. Second, disconnect CO2 quick disconnect from soft drink tank. 2. To connect soft drink tank into Unit syrup system. A. First, connect CO2 quick disconnect to soft drink tank to pressurize tank. B. Second, connect liquid quick disconnect to soft drink tank. Syrup supply should be checked daily and if necessary, replenished as instructed. PRODUCT FLAVOR CHANGE Perform syrup flavor change as instructed. CHECKING CO2 SUPPLY WARNING: CO2 displaces oxygen. Strict attention must be observed in the prevention of CO2 (carbon dioxide) gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high concentration of CO2 gas will experience tremors which are followed rapidly by loss of consciousness and suffocation. Make sure CO2 cylinder shutoff valve is fully opened and regulator assembly 1800-psi gage indicator is not in shaded (‘‘change CO2 cylinder’’) portion of dial. If so, CO2 cylinder is almost empty and must be replaced as instructed. CLEANING AND SANITIZING DAILY CLEANING Daily or more often if necessary, wash all external surfaces of Unit, rinse with clean water, then wipe dry with clean soft cloth. DO NOT USE ABRASIVE CLEANERS.
