Description
Product Summary
The Safgard 550SV is a low water cutoff from Safgard, described by the manufacturer as: 120V low water Cut-Off for hot water with manual reset includes test Button/Light with short EL1214-SV probe. It is rated for 120V. It replaces OEM-170MCSV 45-551.
A low water cutoff shuts the burner off if the boiler water level drops below a safe point, preventing a dry fire that can damage the boiler. Replace a cutoff that does not shut down the burner during its test, has a damaged probe or float, or gives false low-water lockouts after cleaning.
