caused by internal and external noises.
[h] BIN CONTROL SWITCH (Fixed Mounting Only)
The Bin Control Switch is located in the Control Box - Main (see “2. [b] CONTROL BOX
LAYOUT”). The Bin Control Switch employs a photoelectric sensor to measure the depth
by reflected orange LED light. When the Bin Control Switch switches off at the set
distance, the Compressor pumps down and stops after 60 seconds, the Gear Motor stops
after 5 seconds, and the icemaker shuts down.
When stored ice is used, the sensor detects its reduction. Then, the Compressor restarts
after 30 seconds, and the Gear Motor after 15 seconds.
Note: The unit mounting surface requires a bin control hole as well as an ice discharge
hole. See “I. 2. DIMENSIONS/CONNECTIONS” for hole locations.
[i] SPOUT SWITCH (Proximity Switch)
When the Bin Control Switch fails to operate, ice clogs and deforms the Switch Plate to trip
the Spout Switch, and the icemaker shuts down with bin control error. When the error
occurs once (floor mounting) or repeats four times (fixed mounting), “EL” appears in the
display (see “9. ERROR CODES” for details). Remove ice in the Tank Cover (C) and on
the Cutter, and correct the Switch Plate before resuming icemaking operation.

Abnormal Condition (Switch Plate deformed)
[j] CRANKCASE HEATER
Equipments employing a large amount of refrigerant are provided with the Crankcase
Heater to prevent refrigerant migration to the Compressor during off-cycles resulting in oil
shortage at startup. The Crankcase Heater will be energized also when the user turns off
the Operation Switch on the Operation Board.
