The Light Duty Utility Arm (LDUA) is a remotely operated manipulator used to enter into underground waste tanks through one of the tank risers. National Electric Code Requirements mandated that the in-tank portions of the LDUA be maintained at a positive pressure for entrance into a flammable atmosphere. The LDUA Purge Air Supply System (PASS) uses small portable air compressors to provide a constant low flow of instrument grade air for this purpose. This document is used to assure that the instrumentation and equipment comprising the PASS are properly adjusted in order that the PASS can successfully achieve its intended functions.
