Bosch 8733980452 Mini-split Multi-zone Kit 12000 Btu 2 Zone

Product Description

The BOSCH 8733980452 is a multi-zone mini-split system kit designed for residential and light commercial cooling and heating applications. This Generation 4 (G4) MAX series kit delivers up to 12000 BTU/h of total system capacity split across two zones, each served by a 6000 BTU/h indoor unit. The kit ships as a complete assembly including two indoor air handlers, one outdoor condensing unit, and two 25-foot line sets, making it a ready-to-install package for qualified HVAC technicians. It is suited for retrofit and new-construction installations where multiple rooms or zones require independent climate control from a single outdoor unit.

This kit is intended for two-zone ductless mini-split installations in residential settings such as multi-room additions, garages with living space, or small commercial suites. The included components cover the full refrigerant circuit from outdoor unit to each indoor head, with pre-measured 25-foot line sets for each zone. The G4 MAX platform is designed for applications where independent zone control and compact outdoor footprint are priorities. Installation is performed by licensed HVAC technicians familiar with ductless split systems and refrigerant handling.
