Bosch 8733980439 48k 4-zone Mini-split System Kit

Product Description

The BOSCH 8733980439 is a 48,000 BTU multi-zone ductless mini-split system kit configured for four zones. It includes three 9,000 BTU indoor air handlers and one 18,000 BTU indoor air handler paired with a single outdoor condensing unit. Each zone ships with 25-foot line sets, making this a complete package for licensed HVAC technicians handling multi-room or multi-zone residential and light commercial installations. The kit arrives ready to install with matched indoor and outdoor components, reducing sourcing time on multi-zone jobs.

This system is suited for residential applications where four independent comfort zones are required — such as multi-bedroom homes, additions, or spaces that cannot support ducted distribution. The three smaller 9,000 BTU heads cover standard-sized rooms while the 18,000 BTU unit handles larger living areas or open-floor-plan spaces. All indoor and outdoor units are factory-matched within this kit, and the included 25-foot line sets cover typical wall-penetration distances in standard residential construction.

Do not mix line sets or indoor units from other system families with the components in this kit, as factory matching is required for rated performance and warranty validity.
