Bosch 8733980493 48K 4-zone Mini Split Kit

Product Description

The BOSCH 8733980493 is a multi-zone ductless mini split kit rated at 48000 BTU/h, configured for four-zone simultaneous heating and cooling. The kit pairs one outdoor unit with four indoor air handlers, each rated at 12000 BTU/h, making it a complete system package ready for multi-room or multi-zone residential and light commercial installations. Licensed HVAC technicians install this type of system where individual zone control and high-efficiency ductless operation are required. The kit ships as a matched assembly, reducing sourcing complexity for contractors who need both the outdoor and indoor components from a single order.

This kit is suited for residential applications requiring independent temperature control across four separate zones, such as multi-bedroom homes, additions, or mixed-use spaces. Each 12000 BTU/h indoor unit handles a single zone, allowing occupants to set temperatures independently. The system is designed for installation without ductwork, making it a common choice for retrofits or new construction where running ducts is not practical. The kit does not include a line set, so refrigerant piping must be sourced and sized separately per the system requirements.

Key Features

• Complete four-zone kit: one outdoor unit and four matched indoor air handlers included
• System capacity of 48000 BTU/h split evenly across four 12000 BTU/h zones
• Ductless design supports retrofits and new construction without existing ductwork
• Matched component assembly reduces compatibility risk versus mixing units separately
• Line set not included — refrigerant piping sourced and installed separately

Compatibility

Kit includes indoor unit 8733962673 (quantity 4) and outdoor unit 8733962702 (quantity 1). These components are matched at the factory as part of this kit. Do not substitute individual units with outside components without verifying system compatibility with BOSCH documentation.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Shut off all electrical power to the installation area before mounting indoor or outdoor units and before making any wiring connections. Refrigerant line sets are not included and must be sized, routed, and pressure-tested per the manufacturer specifications and local mechanical codes. Follow local building codes and the manufacturer installation manual for mounting clearances, electrical disconnect requirements, and condensate drainage.
