The Manitowoc 000012651 Ice Machine Water Level Probe Assembly High monitors the water level inside compatible commercial ice machines. During operation, the probe senses when water reaches its designated high-level position and sends a signal to the machine’s control system. This input regulates water-level control during the ice-making cycle. The assembly is installed within the machine’s water system near the designated sensing point. It is used in commercial ice makers where water-level monitoring is required for proper cycle control.
