Description
This MRCOOL DIY 5th Generation 48,000 BTU 5-Zone Ductless Mini-Split System pairs a single outdoor condenser with five ceiling cassette indoor air handlers — a 18,000 + 9,000 + 6,000 + 6,000 + 6,000 BTU lineup in this configuration — engineered for do-it-yourself installation with no HVAC professional required.
Highlights
- Pre-charged 25-ft. DIY® QuickConnect® line sets filled with R-454B refrigerant eliminate on-site vacuuming, cutting installation time and cost.
- Rated 21.8 SEER2 and an HSPF2 of 10 for efficient year-round heating and cooling.
- The included DIYPRO® cable removes the need for electrical conduit, adding durability against outdoor elements.
- Control each zone with the wireless remote, the SmartHVAC app (iOS and Android), or hands-free through Amazon Alexa and Google Assistant.
- Each OuttaSight® ceiling cassette fits flush between 16” ceiling joists (including pre-manufactured I-joists), and the Elevation function lowers the filter panel for easy cleaning.
- Backed by a 5-year parts warranty and a 7-year compressor warranty, with a Limited Lifetime Replacement warranty available through the MRCOOL® Care Program.
