Bosch 8733980434 27000 Btu 3-zone Mini Split System

Product Description

The BOSCH 8733980434 is a 27,000 BTU multi-zone ductless mini split system designed for three-zone residential or light commercial cooling and heating applications. This kit includes all major components needed for a complete installation: two 9,000 BTU indoor units, one 18,000 BTU indoor unit, one outdoor condensing unit, and pre-charged line sets. Licensed HVAC technicians install this system as a complete package, reducing sourcing time and ensuring component compatibility across the full assembly. The kit ships at a net weight of 207.95 pounds, making proper staging and crew planning essential before the install day.

This system is suited for applications where separate temperature control across three distinct zones is required, such as multi-room residential builds, additions, or retrofit projects where ductwork is not practical. The two 9,000 BTU indoor units handle smaller rooms or spaces, while the 18,000 BTU indoor unit is sized for larger open areas. The 25-foot line sets included in the kit are appropriate for standard single-story or close-proximity outdoor unit placements. All indoor and outdoor units in this kit are matched components from BOSCH.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Shut down all electrical power to the installation area before making any wiring connections. Refrigerant handling, line set brazing or flaring, and system startup procedures must follow manufacturer guidelines and local mechanical codes. Do not mix components from this kit with unmatched indoor or outdoor units, as system performance and warranty coverage depend on matched component operation.
