Bosch 8733980521 Single Zone Cassette Mini Split Kit 9000 Btu

Product Description

The BOSCH 8733980521 is a single-zone cassette-style mini split system kit rated at 9000 BTU/h, designed for residential and light commercial ductless heating and cooling applications. This kit ships as a matched assembly including one indoor cassette unit, one outdoor unit, and a 25-foot line set, providing all core components for a complete installation. With a SEER2 rating of 22.1 and an HSPF2 of 11.8, the system meets current high-efficiency benchmarks and carries Energy Star certification. A COP of 3.2 at 47 degrees F confirms strong heating performance in moderate cold conditions. Licensed HVAC technicians handle installation and commissioning of this system.

This kit is suited for single-zone ductless applications where a ceiling cassette-style indoor unit is specified. The cassette configuration is commonly installed in commercial offices, retail spaces, hotel rooms, and residential additions where ceiling-mount airflow distribution is preferred over wall-mount or floor-mount units. The included 25-foot line set covers typical single-room and small-zone run distances. Kit components are factory-matched as a system assembly: indoor cassette unit 8733962666, outdoor unit 8733962684, and line set 8733951010.

Compatibility

This kit is built around factory-matched components: indoor cassette unit 8733962666, outdoor unit 8733962684, and line set 8733951010. Components are matched at the system level and should not be substituted with unverified units.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to refrigerant handling requirements. Power down all associated electrical circuits at the breaker before beginning any wiring or mechanical connections. The outdoor unit requires a dedicated electrical circuit sized per NEC guidelines and local code. Do not operate the system for leak testing or commissioning until all refrigerant connections are confirmed leak-free and the system has been properly evacuated.
