Hydrolevel Safgard 700 Low Water Cutoff w/ Manual Reset - 24V

Hydrolevel low water cut-offs are electrically operated. A probe is installed in the boiler shell or external manifold and is connected to the control unit. Water is used as a conductor to complete the circuit between the probe and the boiler shell. When water is in contact with the probe, the circuit is completed; when the water level drops below the probe, the circuit opens. Hydrolevel controls provide contacts to de-energize the burner circuit in a low water condition. 700 Series Interrupts power immediately in a low water condition. Burner circuit locks-out if water remains below probe for 30 seconds. Manual reset will not trip due to power failures. Note: Can also be used as a secondary cut-off on steam boilers Features Heavy-duty electro-mechanical design for long life Automatically shuts off burner in a low water condition to prevent boiler damage Low maintenance. No moving parts to wear stick or hang up, as in float devices. Manual reset feature will not lock out in power failures Specifications Po...
