The MM150 Complete LWCO & Feed is the full mechanical low water cutoff and automatic water feeder assembly engineered for Mr.Steam Commercial CU Steam Room Generators, models CU2000 through CU4500. This assembly governs the entire water fill cycle: when the tank runs dry, the contactor switches off while the water feed solenoid activates, allowing the unit to begin filling. Once water reaches roughly the halfway point on the gauge glass, the contactor energizes the heating elements while the solenoid continues feeding briefly before shutting off, initiating steam production. This float-type mechanical control is essential to safe, automated operation in commercial installations, preventing the heating elements from firing without adequate water while maintaining consistent steam output throughout the day. As a complete assembly, it's the appropriate replacement when multiple components of the mechanical feeder system — rather than a single part like the micro switch or float rod — need to be restored to proper working condition. Built for the demands of continuous commercial use, this genuine Mr.Steam component keeps a CU2000–CU4500 generator's water management system operating safely and reliably.
