[. . . ] FDE470 FDE470 SERVICE MANUAL Purpose of this manual: To provide detailed installation and operation instructions; to give insights into how the machine works; to list possible causes for problems; and to suggest procedures for specific types of service. The FDE470 is an ice maker and dispenser combined into one cabinet. The refrigeration system is air cooled, using R-134a as a refrigerant. The control system uses electric eyes as a bin control and a water level sensor as the water safety control. [. . . ] Pull up on the pull ring to remove the auger. Remove the breaker cover by taking the snap ring out. Use threaded rod or a slide hammer puller and screw into the auger, slide the weight quickly up against the stop to remove the auger.

It has a polished surface that may be either shinny or dull, but must be smooth. After removal, allow the auger to dry to inspect for scale. If mineral scale is found on the auger's surface, clean off the auger with ice machine cleaner and a scrubbing pad. Remove the water seal and clean off the shoulder of the auger. Bearings: The top bearing should spin freely with no rough spots. If it feels rough when spun by hand, replace it. Note: The top bearing used in the FDE470 is a "directional" bearing. Note which way the inner race is configured and install into the breaker. The breaker is also available as a replacement part with the top bearing already installed. The bottom bearing must be removed from the evaporator when replacing the water seal. Remove the three bolts holding the evaporator to the gear motor adapter and lift the evaporator up slightly. Tap the water seal and bottom bearing out from the top down. Check the bottom bearing the same way as the top. Replace the water seal and install a new bearing set if needed. Outer Race Open Sides To replace the water seal: 1. Remove old rotating half from the auger. Place a bead of food grade sealant (such as Scotsman part number 19-0529-01) onto the shoulder of the auger where the rotating half of the water seal will be installed. While wet, slip it onto the bottom of the auger, rubber side toward the auger. [. . . ] Disconnect the electrical wires from the centrifugal switch. Disconnect the water inlet tube from the evaporator.
