How unit works — SensorSAFE models
SensorSAFE models provide "touchless" ice and water dispensing. When a container is placed within the
actuation zone below the ice or water chute on SensorSAFE dispenser models, an invisible, randomly-generated
infra-red signal is emitted, reflected off the container and detected by the sensor. The sensor then sends a signal
to the control board to activate the appropriate components to dispense ice or water. LED's on the board indicate
when the board is receiving a signal from the sensors.
A safety, shut-off feature automatically shuts off 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.
