About this product

The 5th Generation MRCOOL® DIY® Series Outtasight® 9K BTU 230V One-Way Ceiling Cassette provides a powerful and efficient climate control solution for areas up to 400 sq. ft. Designed for simple installation, this unit eliminates the need for specialized tools, making setup quick, cost-effective, and straightforward. Made for multi-zone configurations, the cassette is engineered to fit seamlessly between 16” ceiling joists, including pre-manufactured I-joists, ensuring a discreet, flush-mounted appearance. Unlike conventional ceiling cassettes that require bulky ductwork or dedicated wall space, this unit offers versatile installation, making it a perfect choice for new construction or retrofit applications. This cassette works effortlessly with the MRCOOL® DIY® Quick Connect® line set, which is pre-charged with R-454B refrigerant, an eco-friendly solution that removes the need for vacuuming. It features advanced filtration to improve indoor air quality, while the Elevation function makes filter maintenance easy by lowering the panel for hassle-free access. With whisper-quiet operation and multiple control options—including a wireless remote, SmartHVAC app, and voice control via 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 guarantees long-lasting performance, modern technology, and year-round climate control.
