Gas Filter Change LED (VOC monitoring)
Units equipped with a VOC sensor detect the level of Volatile Organic Compounds in
the exhausted air. If their presence exceeds a preset level the Alarm LED on the front
panel will illuminate. This indicates that the gas portion of the combined filter is
saturated and the filter needs replacing, (See fig 11). The Maintenance section
describes the filter change procedure.
