Bosch 8733980528 Mini-split Kit 27000 Btu 4-zone

Product Description

The BOSCH 8733980528 is a 4-zone ductless mini-split system kit rated at 27,000 BTU/h. The kit ships as a complete set of indoor and outdoor units, giving HVAC technicians everything needed to configure a multi-zone installation in a single order. The system includes two 9,000 BTU/h indoor units, one 6,000 BTU/h indoor unit, one 12,000 BTU/h indoor unit, and one matched outdoor condensing unit. Net kit weight is 208.56 pounds. This kit does not include line sets.

The 8733980528 kit is suited for residential and light-commercial ductless applications where up to four zones require independent comfort control. Typical installations include multi-room residential retrofits, additions, or new construction where running ductwork is impractical. Each indoor unit operates independently, allowing zone-by-zone temperature management from a single outdoor unit. The absence of included line sets means field refrigerant piping must be sourced separately to match actual job-site run lengths.
