The Hydrolevel 750 is a 120-volt low water cut-off control designed to protect hot water and steam boilers from dangerous low water conditions. This essential safety device automatically shuts down the boiler when water levels drop below safe operating levels, preventing costly damage and potential hazards from dry firing.

Key Features:

• Manual reset design ensures operator awareness before system restart
• 120V AC operation for standard residential and commercial applications
• Compatible with both hot water and steam boiler systems
• Direct replacement for obsolete 45-750 model
• Reliable float-type operation for accurate water level detection
• Proven design from Hydrolevel, a trusted name in boiler controls since 1946

The manual reset feature is a critical safety component that requires the operator to physically reset the control after a low water condition occurs, ensuring that the cause of the low water is investigated before the boiler returns to service. This control is suitable for residential, commercial, and light industrial boiler applications where reliable low water protection is essential.
