applications. Versatile and compact, they are easily installed to operate with either a probe- or float-type low water cut-off. The feeders are always ready to add water when given the signal from the LWCO - no need to manually add water. And they protect the boiler from a dry fire condition by maintaining a safe minimum water level in the boiler should a system leak occur. They monitor the water level, maintaining a safe minimum and allow the boiler water line to rise and fall naturally through its normal operating range.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eField-adjustable dwell-feed cycles\u003c\/li\u003e\n\u003cli\u003eMulti-color LED status indicator\u003c\/li\u003e\n\u003cli\u003eManual feed button\u003c\/li\u003e\n\u003cli\u003eHard-stop limit to minimize chances of flooding the boiler\u003c\/li\u003e\n\u003cli\u003eCompatible with all electronic \u0026amp; mechanical\u003c\/li\u003e\n\u003cli\u003eLow Water Cut-Offs\u003c\/li\u003e\n\u003cli\u003eIncludes adapters for connection to �� copper tubing\u003c\/li\u003e\n\u003cli\u003eRemovable strainer (replace after cleaning)\u003c\/li\u003e\n\u003cli\u003eMaximum water pressure 150 psi (10.5 kg\/cm2)\u003c\/li\u003e\n\u003cli\u003eMaximum boiler pressure 15 psi (1 kg\/cm2)\u003c\/li\u003e\n\u003cli\u003eMaximum water temperature 120�F (49�C)\u003c\/li\u003e\n\u003cli\u003eMaximum ambient temperature 100�F (38�C)\u003c\/li\u003e\n\u003cli\u003eMaximum power consumption (during feed cycle)\u003c\/li\u003e\n\u003cli\u003e15 VA @ 24VAC\u003c\/li\u003e\n\u003cli\u003e20 VA @ 120 VAC (50 or 60 Hz)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWant to learn more about this water feeder?
