Bosch 8733980433 27000 Btu 3-zone Mini Split Kit

Product Description

The BOSCH 8733980433 is a complete 3-zone mini split system kit rated at 27,000 BTU total cooling and heating capacity. The kit includes all major components needed to configure a multi-zone ductless installation: two 9,000 BTU indoor units, one 12,000 BTU indoor unit, one outdoor condensing unit, and the corresponding 25-foot line sets for each zone. This assembly is sized for residential or light-commercial applications where multiple rooms or zones require independent temperature control. HVAC professionals install this type of system when zoning flexibility and energy efficiency are priorities over ducted alternatives.

This kit is designed for 3-zone ductless mini split installations. The two 9,000 BTU indoor units suit smaller rooms, bedrooms, or offices, while the 12,000 BTU indoor unit is appropriate for medium-sized living spaces or open areas. Each zone operates independently, allowing occupants to set different temperatures per space. The included 25-foot line sets are sized for standard residential room-to-outdoor-unit runs. This configuration is commonly used in residential additions, multi-room retrofits, and light-commercial spaces where duct installation is not practical.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 refrigerant handling certification. Power down all electrical circuits at the breaker panel before working on any component. Each zone requires proper line set routing, refrigerant evacuation, and leak testing before startup; do not operate the system without completing a full vacuum procedure on all lines. Local mechanical and electrical codes govern mounting height, disconnect requirements, and condensate drainage — consult applicable codes before beginning work.
