Technical Documentation

Current public technical documents

Use the DueNorth document library to identify public technical documents by title, part number, version, date, and release status before relying on them for project work.

Document control

Verify the current document before use

Technical documents may be revised. Verify the title, part number, version, date, and release status before using a document for selection, design, installation, commissioning, inspection, maintenance, service, quotation, specification, or submittal work.

Superseded, preliminary, translated, extracted, reformatted, or third-party copies must not be treated as controlling unless DueNorth has expressly identified them as current and approved for use.

Document use

Website documents do not replace project-specific requirements

Public technical documents must be used together with the applicable system configuration, approved design method, project drawings and specifications, applicable standards, certification records, qualified system design, and AHJ requirements.

A public manual does not by itself establish approval or certification of every system configuration.
