Hydrolevel 550R Low Water Cut-Off with Manual Reset and Remote Probe

The Hydrolevel 550R SAFGARD is a 120-volt commercial-grade low water cut-off (LWCO) designed to protect hot water boilers from dangerous low water conditions. This model features a remote mounting configuration with an EL1214-R sensing probe, allowing the control box to be installed separately from the boiler for convenient accessibility.

Key Features:

• Interrupts power immediately when low water condition is detected
• Manual reset function that locks out the burner circuit after 30 seconds if water remains below probe level
• Built-in test button allows verification of control operation and lock-out function without lowering water level
• LED indicator lights provide clear visual status of power and operation
• Manual reset will not trip due to power failures, ensuring reliable protection
• Remote mounting probe (EL1214-R) provides installation flexibility
• SPDT switch contacts with 5.8 full load amps, 34.8 locked rotor amps capacity

This unit is suitable for gas or oil-fired hot water boilers and can also function as a secondary cut-off on steam boilers up to 250 PSI. The water in the boiler acts as a conductor to complete the circuit between the probe and boiler shell, providing reliable electronic monitoring of water levels.
