Fluid Handling LLC. has recalled approximately 1,700 McDonnell & Miller Low Water Cut-Off control units because the ground wire and probe wires could be installed incorrectly posing fire and explosion hazards. The low water cut-off control units are used on hot water or steam boilers as a primary or secondary safety control in the event of low water conditions.
The McDonnell & Miller series 750 control units are mounted on the outside of the boiler, close to the boiler’s main electrical panel. They are black boxes with a green LED “On” light, a red LED “Low Water” light, and other buttons on the top. The company is providing free inspection, repair, or replacement of recalled units.
