The dual float switch contains two large floating rings enclosed within a protective cage. Water will lift the bottom float by a 1⁄4, which will activate the pump. If for any reason the lower float does not activate the pump, the water will rise and
activate the second switch. As the pump evacuates the water from the pit the floats will drop. The pump will run for an additional 10 seconds to extend the cycle after the lower float drops.
Note: When mounting the float switch, position the
bottom of the cage at the height you want the pump to activate.
