Abstract

A device (20) for Disinfection of HVAC Systems that include features that will protect service personnel from un-intended exposure to ultra violet radiation. The safeguards include an interlock (70) that prevents illumination of germicidal lamps (80) when an enclosure within which the germicidal lamps (80) are mounted is not properly attached to a duct or appliance; the apparatus further provides for innovative methods for determining that the germicidal lamps (80) are operating.
