Hoshizaki C-100BAF-AD B. Sequence of Operation, Freeze Cycle, Bin Control Thermostat Shutdown

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 depends on the inlet water and ambient temperature conditions.

The float-operated water valve allows water into the reservoir as needed to continue the ice making process. This continues until BC shuts down the icemaker or power is turned off to the icemaker.

2. Bin Control Thermostat Shutdown

Ice fills storage bin to level of BC. When BC opens, GM, FM, CR, and Comp de‑energize. When ice level lowers and BC closes, the icemaker starts operating again.
