This Lochinvar safety device is a Low Water Cut Off (LWCO) Kit designed to protect hot water boilers from the potentially damaging effects of low water conditions. The kit includes a probe, which is inserted into the boiler, and a control module that monitors the water level. If the water level drops below a predetermined point, the control module will automatically shut off the boiler to prevent overheating and potential damage. The LWCO kit is compatible with select models of Lochinvar boilers and is designed for easy installation. It operates on a 120-volt power supply and features an LED indicator light for operational status visibility.
