Hydrolevel Safgard 550P is a 120V commercial-grade low water cut-off w/ long probe, manual reset and test buttons for Gas or Oil-fired hot water boilers (or as a secondary LWCO on steam boilers). Immediately interrupts power in a low water condition, locks out burner circuit if water remains below probe level for longer than 30 seconds. Manual reset will not trip due to power failures. Test button simulates low water condition and allows for checking control without lowering the water level in a system.

  • Meets ASME CSD-1 requirements for commercial applications
  • Suitable for Gas or Oil-fired boilers
  • Separate Test button for easy diagnostics without lowering the water level or removing the probe
  • Separate Manual Reset button with nuisance lock-out protection (will not trip due to power failures)
  • LED indicators for power and low water
  • Suitable for use as a secondary control on residential and light commercial steam boilers
  • Low maintenance - no blowdown or moving parts
  • Multiple wiring options
  • Contacts for optional low water alarm

Technical Specifications:

Excellent Service
Required two sweat check valves and my "big box" store only stocked threaded units. Went online, ordered and they were here in two-three days. Did not have to drive to store and arrived quickly. Great fast service.
