2 6.0 Scope This Specification is intended to provide general, specific, salient features and other attributes and requirements for a high pressure air knife automated Catalyzed Soot Filter and Dual Oxidation Catalyst (CSF/DOC) cleaning system. The CSF/DOC cleaning system shall by incorporation of necessary equipment and facilities services provide a system that measures CSF/DOC pressure differential for filter qualification and verification of process result, provides a chamber based automated fixture that cleans the inlet and outlet of CSF units by programmed mechanical action and removes soot and containments to containers for proper, disposition. This specification shall define the requirements for two (2) operating lineups. The specification shall require both operating lineups at full service in simultaneous operation. Operating line ups are defined by 7.0 herein. The system as delivered and commissioned for operation shall be complete with all interconnecting ducting provided by the Contractor. The Contractor (supplier of equipment) shall support a commissioning procedure as defined herein. No advantage shall be taken by the Contractor where the omission of parts, materials and/or system descriptions as specified herein, shall inhibit the installation and delivery of a fully functioning CSF/DOC cleaning System. The equipment shall comply with all applicable requirements of the CFR Title 49, The Commonwealth of Pennsylvania and FMVSS, NHTSA, ADA and EPA regulations and other codes and conventions affected or specified herein. 7.0 General description and Salient Features Each operating set or line up shall require 460 Volt Alternating Current 3 60 ampere service in operation. Two (2) sets or line ups may be in operation simultaneously thereby imposing a 460 Volt Alternating Current amperes to required electric services.
