Bosch 8733980421 Mini Split 36000 Btu 3-zone System Kit

Product Description

The BOSCH 8733980421 is a multi-zone ductless mini split system kit rated at 36000 BTU, configured for three zones. The kit bundles an outdoor condensing unit, two indoor air handler units, and pre-cut line sets into a single order, reducing procurement steps for the installing contractor. One indoor unit is rated at 24000 BTU and two units are rated at 6000 BTU each, allowing a mix of high-load and low-load zones within a single system. Licensed HVAC technicians handle installation, which involves refrigerant line connection, electrical rough-in, and low-voltage control wiring. The total kit net weight is 257.19 pounds.

This kit is suited for residential and light commercial applications where multiple rooms or zones require independent temperature control without ductwork. Typical scenarios include new construction, additions, or retrofits where running duct is impractical. The 25-foot line sets included in this kit cover standard single-story or short-run multi-story installations. The configuration of one large zone and two smaller zones fits common layouts such as a primary living area paired with two secondary rooms or offices.
