Surface Mounting Frame for Large HVAC Units
This Dayton 2YU99 frame provides a surface mounting solution for compatible HVAC controls. It is designed for use with models 54UD18 through 54UD21 and fits units rated from 500 to 750 kW. The steel construction is finished in gray and carries UL and CUL listings. Installers working on large commercial air-handling equipment will find this frame matches the required footprint.
Verify Unit Model and Mounting Surface Before
Confirm that the existing HVAC control carries one of the listed model numbers: 54UD18, 54UD19, 54UD20 or 54UD21. The frame is intended for surface mounting only and extends 1/8 in from the wall, so the mounting surface must be flat and able to accept the supplied hardware. No other model numbers or mounting types are supported by this frame.
Steel Frame Kit with Included Fasteners
The package contains two side frames, two end frames and eight screws for assembly. Steel material and the 1/8 in standoff provide a rigid, code-compliant installation that holds the control away from the mounting surface. Gray finish resists corrosion in mechanical rooms. The frame dimensions are 48 in by 24 in outside height and width.
