Bosch 8733980512 Mini Split 27000 Btu 3 Zone System

Product Description

The BOSCH 8733980512 is a multi-zone ductless mini split system rated at 27000 BTU/h total cooling and heating capacity across three indoor zones. This kit includes two 9000 BTU/h indoor units and one 18000 BTU/h indoor unit paired with a single outdoor condensing unit, allowing independent temperature control in up to three separate spaces from one outdoor installation. The system ships without a line set, so line sets must be sourced separately to match the actual installation distances. Licensed HVAC technicians install this equipment in residential and light commercial applications.

This multi-zone system is suited for residential homes, condos, apartments, and light commercial spaces where ductwork is impractical or unavailable. The three-zone configuration supports mixed room sizes — pairing the two smaller 9000 BTU/h heads for bedrooms or offices with the larger 18000 BTU/h head for a living area or open space. The absence of an included line set makes it adaptable to installations where run lengths vary by job.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification, as this system involves refrigerant handling. Disconnect all power at the breaker before making any electrical connections to indoor or outdoor units. Line sets, electrical whips, and disconnect boxes are not included and must be sized according to the equipment specifications and applicable local codes. Follow the manufacturer installation manual for refrigerant line sizing, flaring procedures, and nitrogen pressure testing before charging.
