Bosch 8733980520 36000 Btu 4-zone Mini-split System

Product Description

The BOSCH 8733980520 is a 36,000 BTU 4-zone ductless mini-split system designed for multi-room heating and cooling in residential and light commercial applications. The kit includes two indoor air handler units and one outdoor condenser unit, pre-matched for optimized performance. Each indoor unit connects to the outdoor unit via 25-foot linesets included in the package. This system is intended for installation by licensed HVAC technicians and is well suited for homes or buildings where zoned comfort control is required without the need for ductwork.

This 4-zone configuration supports independent temperature control across multiple spaces simultaneously. The system ships as a complete kit with all major components — two indoor units (IDU) and one outdoor unit (ODU) — reducing sourcing time on multi-zone jobs. The grille is included with the indoor units. This system targets residential new construction, retrofit applications, and light commercial spaces where duct installation is impractical or cost-prohibitive.

Installation Notes

Installation must be performed by a licensed HVAC technician familiar with ductless mini-split systems. Power down all circuits before connecting or servicing any system components.
