Manual NU-162 and 164 E G December 1998.PDF

This document is an Operation and Maintenance Manual for Polypropylene Fume Hoods, Models NU-162/164(E)(G) manufactured by NuAire, Inc. in Plymouth, Minnesota. The manual covers bench top fume hoods designed for laboratory use, detailing comprehensive information about hood types, construction features, models, testing procedures, and specialized applications.

The fume hoods are constructed from stress-relieved white polypropylene, 100% metal-free, and intended for high-acid environments in fields like trace metal analysis, toxicology, semiconductor development, and prototype/production operations. The manual describes multiple hood configurations including conventional, bypass air, auxiliary air, and special purpose hoods (such as radioisotope and perchloric acid hoods). Key technical specifications include various width and depth options (424-824 inches), work area dimensions, exhaust requirements, and rigorous testing standards like SEFA 1-1992 and ASHRAE Standard 110-1995, which evaluate face velocity, smoke flow patterns, lighting intensity, and electrical safety. The document also provides detailed guidance on installation, warranty terms, shipping procedures, and safety considerations for specialized acid-related applications.
