Place shaft seal locator seat over gear motor output shaft, embossed side down, and push down until shaft seal seat rests flush on top of gear motor. 2. Place rubber coated ceramic seal E–RING (important: ceramic face up) over output WASHER, PLAIN FLAT shaft and push down until seal rests on top of the shaft seal seat. (Lubricate rubber on SHAFT SEAL ceramic seal with rubber lubricant.) LOCATOR SEAL 3. Place shaft seal with carbon face down (spring up) over output shaft and push (gently) downward until seal rests on ceramic face of the output shaft seal. 4. Place flat washer over output shaft and let GEARMOTOR rest on the output shaft seal. Push down on the washer compressing the spring on the output shaft seal. While holding the seals (down) in place slide the E–ring into the groove on the output shaft. AUGER AND EXTRUDING HEAD REMOVAL 1. Disconnect unit from power supply. 2. Remove storage container cover and put aside. 3. Turn off water supply to icemaker. 4. After ice has melted from head take hold of the auger nut and lift straight up to disengage from icemaker. 5. When replacing the auger assembly, make certain that both the auger engages the output shaft drive and the extruding head ribs engage the evaporator tube. FIGURE 16.

SHAFT SEAL 700 AND 1000 E–RING WASHER, PLAIN FLAT SHAFT SEAL SEAT, SHAFT SEAL GEARMOTOR MOUNT, SHAFT SEAL INSTALLATION AND SHAFT SEAL REPLACEMENT 700 & 1000 1. Place shaft seal locator seat and shaft seal mount over gearmotor output shaft and push down until shaft seal seat and shaft seal mount rest flush on top of gearmotor. 2. Place rubber coated ceramic seal (important: ceramic face up) over output shaft and push down until seal nest in recess of shaft seal mount. (lubricate rubber on ceramic seal with rubber lubricant). 3. Place shaft seal with carbon face down (spring up) over output shaft and push (gently) downward until seal rests on carbon face of the output shaft seal. 4. Place flat washer over output shaft and let rest on the output shaft seal. Push down on the washer compressing the spring on the output shaft seal. While holding the seals (down) in place slide the E–ring into the groove on the output shaft UPPER NUT AND BEARING ASSEMBLY The upper white bearing located on top of the auger is used to absorb the force between the auger and extruding head. NOTE: The bearings are 3/32 thick. When they wear below 1/16 they should be replaced. Bearings to be inspected for wear during quarterly maintenance. To Replace Bearing 1. Disconnect unit from electric power. 2. Remove top panels. 3. Remove Dispense Tray Cover. 4. Use an open end wrench on auger nut connected to bearing and turn counterclockwise to remove assembly. 5. Remove worn bearings. Replace with new bearings and then reinstall assembly. NOTE: If auger turns with nut, remove cover on top of gearmotor stator and hold motor while loosening nut. ELECTRICAL CHECKOUT 1. Be sure the unit is disconnected from the power source. Remove the compressor electrical box cover. Check for obvious damage and loose wires. 2. Disconnect the fan motor leads. Since capacitors store energy, short the capacitor with a screwdriver. This will prevent shocks. 3. Disconnect the compressor terminal wires. © 2004-2005, IMI Cornelius Inc. - 17 - Publication Number: 630460174SER Continuous Flow Icemaker Service Manual OVERLOAD CHECK Using a volt–ohmmeter check the continuity across the overload, contact #1 and #3. If none, wait for unit to cool down and try again. If still no continuity, the overload protector is defective and should be replaced. FIGURE 18. OVERLOAD CHECK COMPRESSOR CHECK The resistance readings on the windings will be between 0.25 to 10.00 ohms, a meter capable of these low readings must be used. 1. Check between “C” and “R.” Replace the compressor if there is no continuity as the run windings are open. 2. Check between “C” and “S.” Replace the compressor if there is no continuity as the start windings are open. 3. Check between “C” and “R” or “S” and the shell of the compressor. If there is continuity, replace the compressor as the motor is grounded. 4. Check between screw terminal on the overload and “C” on the compressor. Check and repair the lead or connections if there is no continuity. CAPACITOR CHECK 1. Check or replace start capacitor, FIGURE 19. COMPRESSOR CHECK disconnect bleed resistor before checking for shorted capacitor. 2. Check or replace run capacitor (if supplied) check for shorted capacitor or either terminal grounded to case.
