B. Sequence of Operation This icemaker utilizes a thermostatic bin control to switch the gear motor, fan motor, and compressor on and off as needed. This icemaker utilizes a float-operated water valve in the water reservoir to allow water into the icemaker as needed. After the power switch is placed in the "ON" position, the sequence is as follows: 1. Freeze Cycle GM, FM, CR, and Comp energize. As the water in the evaporator cools, ice starts forming within 4 to 6 minutes. This time frame d

c) Low Water/Freeze-Up Safety Shutdown If the water supply is interrupted or a freeze-up condition occurs, the decrease in suction line temperature causes the suction temperature safety to open and shut down the icemaker. See the table below for suction temperature safety cut-out/cut-in temperatures. Suction Temperature Safety Cut-out 23.9°F±2.7°F (-4.5°C±1.5°C) Cut-in 29.0°F±2.7°F (-1.5°C±1.5°C) (external overload 2.4~3.0A) (3W) (internal) (external) C-100BAF Series 14

d) Gear Motor Protector (external overload) Shutdown If gear motor amperage exceeds 2.4~3.0 amps, the gear motor protector (external overload) operates independently to turn off the gear motor. The gear motor external overload can be manually reset by pressing the switch on the control box. (external overload 2.4~3.0A) (3W) (internal) (external) C-100BAF Series 15

e) Optional Drain Pump HS-0248 Safety Shutdown If the water level in the drain pump reservoir rises high enough to close the drain pump upper float switch, the drain pump safety interrupts power to the icemaker. When the water level lowers enough to open the drain pump upper float switch, power is restored to the icemaker. The pump motor remains energized as long as the drain pump lower float switch is closed. (external overload 2.4~3.0A) (3W) (internal) (external) C-100BAF Series 16

5) Shutdown (bin full) – Ice fills storage bin to level of BC. BC opens. GM, FM, CR, and Comp de-energize. Diagnosis: When the icemaker is running, hold ice in contact with BC bulb. If the components fail to de-energize, check BC. 6) Move the power switch to the "OFF" position and unplug the unit from the electrical outlet. 7) Make any repairs necessary, then replace the removed parts in the reverse order of which they were removed. 8) Plug the unit back in. Move the power switch to the "ON"
