    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL 4. RECEIVING AND UNPACKING DISPENSER 4.1 Receiving Each dispenser is tested and thoroughly inspected before shipment. At the time of shipment, the carrier accepts the dispenser and any claim for damages must be made with the carrier. Upon receiving the dispenser from the delivering carrier, carefully inspect carton for visible indication of damage.

  • Page 7: Self-Contained Refrigeration Models

    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL 5.2 Self-Contained Refrigeration Models Adequate clearance around the dispenser is required for proper air flow. Failure to provide proper clearance will reduce capacity and can eventually damage the refrigeration system. See the specifications page for clearance requirements. Be careful of enclosed installations that can recirculate hot discharge air.

  • Page 8: Connecting To Water Supply

    Note: According to the National Sanitation Foundation (NSF), an ASSE 1022 approved backflow prevention device must be installed on the water supply line before connecting to the dispenser. If needed, one can be purchased from FBD under part number 12-2272-0001. The backflow device must have a line connected to the vent that diverts any flow to a drain.

  • Page 9: Connecting To Co2 Supply

    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL 5.6 Connecting to CO2 Supply The CO2 supply may come from either an independent tank with a primary/secondary regulator or a bulk tank that supplies other equipment. If the supply is from a bulk tank, supply pressure must not exceed 120 PSIG (827 kPag). Tee off the main line and install a wall-mounted secondary regulator set to 70 PSIG (483 kPag).

  • Page 12: Brixing

    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL 6.3 Brixing The brix for each barrel must be verified and adjusted for optimal performance. Use the following procedure to set the brix for each barrel: Turn the syrup shutoff valve to the off position (Figure 6.2). Adjust the water flow rate to 1.5 oz/sec (44.4 ml/sec) by dispensing water from the solution module through the sample port for 10 seconds into a measuring cup.

    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL 7. DISPENSER OPERATION Operation of the dispenser is simple because many of the operations/functions are automated. 7.1 Freeze To freeze the product down, press the up or down arrows on the keypad until the desired barrel is highlighted and then press the RUN button.

  • Page 15: Drink Too "Firm" Or Cold

    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL 7.5 Drink Too “Firm” or Cold A drink that is over-frozen will tend to be very cold, below 22°F (-5.5°C), and can be considered hard and difficult to suck through a straw. It can also be lighter in weight than a properly frozen drink and tends to collapse in the cup after being dispensed.

  • Page 16: Cleaning And Sanitizing

    Failure to properly clean and sanitize the dispenser can negatively affect components, drink quality, and dispenser operation. FBD recommends that the dispenser be sanitized annually or when the dispenser has been non-operational for an extended period of time.
  • Page 17 37X INSTALLATION & OPERATION MANUAL 372/373 MODEL Once the barrel has defrosted, navigate to the MANUAL ON/OFF menu located under the SERVICE MENU section and activate both the CO2 and solution solenoids for the barrel to be sanitized. Place a large container under the dispensing valve and drain the barrel. Activating the beater motor will facilitate draining the barrel when near empty.

  • Page 18: Preventive Maintenance

    Check the Fault Code History in the menu (Section 10.7). If there are repeated beater low errors, inspect blades for damage (chips, cracks, warping, excessive wear) and dullness. The blade edge should be sharp and smooth. If damage or dullness is found, replace blades using an FBD blade/spring kit (purchased separately).

  • Page 19: Rear Seal Replacement

    The motor rear seals must be replaced annually. Failure to do so can result in rear seal leaks and potential motor failures. If the dispenser has been in storage for longer than 90 days, FBD recommends that the rear seals be replaced. The rear seal can be replaced from the front of the dispenser.

  • Page 20: Backflow Preventer Maintenance

    37X INSTALLATION & OPERATION MANUAL 372/373 MODEL APPENDIX A: 372 “NITROFUB” The 372 “Nitrofub” dispenser, is a unique dispenser with barrel one configured for Nitro-FCB (expanded drink) and barrel two configured for FUB (drink with no expansion). The second biggest difference from a standard 372 is the Nitrofub dispenser’s usage of Nitrogen (N2).
  • Page 54 37X INSTALLATION & OPERATION MANUAL 372/373 MODEL A5.6 Connecting to N2 Supply The Nitrofub dispenser will require a connection to CO2 as stated in Section 5.6; however, that CO2 supply will only be used for operating the pumps. The Nitrofub dispenser will also need to be connected to an N2 supply to be used for the Nitro- FCB barrel.
  • Page 55 37X INSTALLATION & OPERATION MANUAL 372/373 MODEL A10. MENUS AND NAVIGATION A10.6 Readouts Menu The COMMON READOUTS will show Nitrogen (N2) readouts instead of CO2. Figure A10.1 A10.9 Maintenance Menu On Nitrofub dispensers, the GAS PURGE procedure uses Nitrogen (N2) to purge air from the barrel instead of CO2. A10.10 Settings Menu On Nitrofub dispensers, the EXPANSION ADJUSTMENT is used to adjust the amount of Nitrogen (N2) in the drink instead of CO2.
