This sleek, ceiling-recessed unit pairs with MRCOOL® DIY® 4th Gen Multi-Zone Condensers and connects via Pre-Charged Quick Connect® Line Sets—factory-filled with R-410A refrigerant. No vacuuming. No special tools. Just secure the connection and power on. For added range, use a No-Vac® Coupler to extend the line set without hassle.
Control your comfort with the included remote or go smart with the SmartHVAC® app, Amazon Alexa, or Google Assistant. The Elevation function lowers the filter panel up to 4.9 ft for effortless maintenance, while whisper-quiet performance and air-swing technology ensure even coverage in every corner.
Backed by a limited lifetime compressor warranty (with registration), 7-year compressor, and 5-year parts coverage, the 9K OuttaSight® cassette is the perfect blend of elegance, performance, and convenience.
