About this product

The 5th Generation MRCOOL® DIY® Series Outtasight® 18K BTU 230V One-Way Ceiling Cassette provides efficient and powerful climate control for areas up to 800 sq. ft.

Ideal for both multi-zone and single-zone applications, this unit fits seamlessly between 16” ceiling joists, including pre-manufactured I-joists, ensuring a flush, modern appearance.

It connects effortlessly to the MRCOOL® DIY® Quick Connect® line set, pre-charged with R-454B, an eco-friendly refrigerant, eliminating the need for vacuuming and simplifying the installation process. Advanced filtration improves indoor air quality, while the Elevation function allows the filter panel to lower for easy maintenance and cleaning. With whisper-quiet operation and multiple control options—including a wireless remote, SmartHVAC app, and compatibility with Amazon Alexa and Google Assistant—this system ensures customized comfort. Supported by a 7-year compressor/5-year parts warranty and eligibility for the MRCOOL® Care Program, the MRCOOL® Outtasight® Ceiling Cassette offers reliable performance and year-round comfort.
