The CMC-31 kit contains the components required to monitor the amount of restriction in the air filter to signify when filter replacement is required. An indicator light will illuminate as well as a set of normally open contacts will latch closed upon activation of the pressure differential switch. The light will stay illuminated and the contacts closed until the reset button is pushed or unit power is cycled. The pressure differential switch is adjustable to be set at the desired filter restriction level.
