Page 32: Dispenser Bracket
Ice level management is recommended to prevent water leakage or movement of ice machine during agitation. See "Ice Level Sensor Setup" (pg. 33). Follow the dispenser unit, adapter kit, or top kit instructions for securing the ice machine. If no instructions are available, secure the ice machine with the provided mounting brackets. -
Page 33: Ice Level Sensor Setup
Installation & Setup (cont.) Ice Level Sensor Setup The ice level sensor utilizes Time of Flight (TOF) technology to detect the amount of ice in the ice storage unit. The sensor has a safe class 1 laser with no possibility of eye damage. - Page 34 Press the values to open the number pad. Enter the desired setting and press ok. • Full Bin Distance (FBD) is the distance in centimeters between the sensor and the ice when the machine enters the FULL BIN state with the damper held down. See fig. 1.
- Page 35 The machine will enter the FULL BIN state once the Value is greater than the Full Bin Ice Threshold [PBD]. For instance, if PBD is set to 50, then the ice machine will enter the FULL BIN state when the Value is greater than 50% (in other words, when the ice storage unit is at least half full).
