6. Wipe all bin surfaces with Solution A. 7. Rinse thoroughly with clear, potable water. 8. Wipe with Solution B to sanitize. 9. Reinstall dispense wheel and other components. ! To avoid possible damage to motor assembly, use a damp cloth only. Do not allow water to run through center hole in bottom of bin area. If dispenser is equipped with chilled water accessory: 1. Remove four screws securing splash panel. 2. Disconnect 19mm (3/4") drain line from bottom of chilled water canister. 3. Loosen (do not remove) screw securing front bracket of chilled water canister to bottom of dispenser hopper. 4. Rotate canister clockwise to release front bracket, then pull canister forward to disengage rear bracket. 5. Remove chilled water coil from canister and clean with cloth wrung out in Solution A. 6. Wipe inside of chilled water canister with cloth wrung out in Solution A. 7. Rinse all above items with damp cloth wrung out in clear water. 8. Sanitize all above items with damp cloth wrung out in Solution B. Do not rinse. 9. Reinstall chilled water coil into canister (rubber alignment grommet on coil tubing must be located outside chilled water canister to hold coil securely against canister wall). 10. Reinstall chilled water assembly on dispenser and tighten screw securing front bracket. 11. Reconnect 19mm (3/4") drain line to chilled water canister. 12. Reinstall splash panel and top front cover. 13. Restore power and test operation. Quarterly cleaning of icemaker system Units with icemakers require icemaker cleaning at least every 3 months, and more often if local water conditions dictate. Failure to clean icemaker will result in decreased performance and potential damage to icemaker. Refer to Icemaker Operation and Service Manual for specific cleaning instructions. 17 Service information Wiring diagrams How unit works — lever models The dispense wheel motor is energized through the power and ice dispense switches. The water solenoid valve is energized through the power and water dispense switches. The icemaker receives the bin signal through the normally closed bin thermostat and the bin signal switch. When the bin level thermostat is calling for ice, a 16V circuit is completed to the bin signal terminals on the icemaker circuit board. When ice builds up around the bin thermostat, the contacts open, opening the circuit to the bin signal terminals on the icemaker circuit board.

When a container is placed within the actuation zone below the ice or water chute on SensorSAFE dispenser models, an infrared signal reflects off the container and is detected by the sensor. The sensor then sends a signal to the control board to activate the appropriate components to dispense ice or water. LEDs on the board indicate when the board is receiving a signal from the sensors. A safety, shut-off feature automatically stops the unit from dispensing after one minute of continuous activation. Dispensing can be restarted by moving the container away and then returning it to the actuation zone. Dispensing can be temporarily suspended for cleaning by depressing and releasing the clean switch, located under the left side of the top front cover. Depressing and releasing the button a second time will return the dispenser to normal operating state. If the clean switch is not depressed a second time, the dispenser will automatically resume normal dispense operation (CLN LED goes out) after two minutes. An LED on the control board will light to indicate that the dispensing has been suspended by activation of the clean switch.

Disconnect power to dispenser and icemaker before putting hands or arms in storage area, or attempting any repair or service to equipment. Before calling for service: • Check that there is ice in dispenser bin area • Check that all switches and circuit breakers are on • Check that congealed cubes are not causing a jam • Check that all drains are clear Symptom Possible cause Solution 1. Does not dispense ice. a. Power switch off or faulty. b. Faulty dispense switch. c. Wheel motor malfunction. d. Drive chain off. e. Sprocket key missing. a. Check switch; turn on or repl...
