Motors and variable frequency drives.
Fabrication: Conform to AMCA 99 in the absence of direction in this Specification.
Performance parameters, and design data: Refer to schedules on the Drawings.
Provide a unit with a total footprint size (length and width) that will not exceed the one shown on the Drawings, including the height of individual unit components.
Dual duct units shall have separate hot deck and cold deck fan arrays.
Units shall be a draw-through configuration except for dual duct hot deck units which shall be a blow-through arrangement.

unit casing, frame, and general construction
Unit Casing: The casing shall consist of double wall panels, and also have reinforced construction with sufficient internal welded steel structure frame and bracing to prevent excessive deflection of the casing panels.
Exterior walls minimum 16-gage G-90 galvanized steel.
Internal insulation shall expanded foam type and have a minimum R-value of 12.
Protect all internal insulation with solid galvanized sheet metal inner panels of minimum 18-gage G-90 galvanized steel. All sheet metal joints throughout the air-handling unit and between panelized sections shall be gasketed with closed cell, soft rubber gaskets, fabricated from neoprene, EPDM or other approved material.
Where the air unit casing encloses the building columns, provide airtight enclosure. Leakage rate will not exceed that allowed for the unit casing.
Maximum deflection at any point on the unit casing shall be limited to 1/200th of the overall panel width or height. The unit casing leakage shall not exceed 0.5 CFM per square foot of cabinet area at the scheduled inches positive or negative static pressure
