Specifications & product details

Hydrolevel Safgard Low Water Cut-Off – Model 45-550

Manual Reset | Test Button | CSD-1 Required

The Hydrolevel Safgard 45-550 is a manual-reset low water cut-off designed for residential and commercial boiler systems. This control is CSD-1 compliant and commonly required as a secondary LWCO on steam boilers.

The Safgard monitors boiler water level using a probe and opens the burner circuit after a 2-second delay when low water is detected. The control locks out if water remains below the probe for 30 seconds, protecting the boiler from dry firing.

Key Features

Manual reset prevents automatic restart
Integrated test button for burner circuit verification
Will not nuisance trip due to air bubbles or power interruptions
Can be used as:

Secondary LWCO on steam boilers
Primary LWCO on hot water boilers
