FPS-B Series (HVAC/R) Liquid Level Sensor bracket model flood prevention switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Ideal in commercial or residential installation to primary or auxiliary condensate drain pans. This model includes a custom bracket that clips onto primary or auxiliary drain pans. UL508, NEC and IMC compliant.
