Ultra Aire 4037766 Surface Mount Kit MD33 Dehumidifier

Product Description

The ULTRA AIRE 4037766 is a surface mount kit designed for permanent wall installation of the Ultra Series MD33 in-wall dehumidifier. It provides a secure mounting solution when a through-the-wall installation is not feasible, such as on masonry or CMU block construction. The kit allows the MD33 unit to be mounted directly to the wall surface rather than recessed, preserving structural integrity where cutting through the wall is not an option. HVAC technicians and installers working in below-grade or concrete block environments will find this kit essential for code-compliant, stable dehumidifier placement.

This surface mount kit is intended for use with the Ultra Series MD33 in-wall dehumidifier in residential and light commercial applications. It is particularly well-suited for installations in basements, crawlspace-adjacent spaces, or any area where masonry or CMU block walls are present and through-the-wall mounting is unavailable. It is installed as a permanent fixture, making it appropriate for new construction as well as retrofit projects where structural constraints limit standard recessed installation methods.

Key Features

• Enables surface mounting of the MD33 in-wall dehumidifier to masonry or CMU block walls

Compatibility

Installation Notes

Installation should be performed by a qualified HVAC technician or contractor familiar with dehumidifier systems and wall-mounting hardware. Prior to installation, ensure the dehumidifier unit is fully powered down and disconnected from any electrical supply. Appropriate masonry anchors and fasteners for CMU or concrete block surfaces should be used to ensure a secure, permanent mount. Follow all local building codes and the manufacturer installation instructions throughout the process.
