Bosch 8733980523 Mini Split Cassette Kit 18000 Btu/h

Product Description

The BOSCH 8733980523 is a single-zone mini split cassette system kit rated at 18000 BTU/h, designed for residential and light commercial cooling and heating applications. The kit ships as a complete matched system including one indoor cassette unit, one outdoor unit, and a 25-foot line set, allowing installers to complete a single-zone installation without sourcing components separately. With a SEER2 rating of 22.2 and an HSPF2 of 12.2, the system meets high-efficiency benchmarks and carries Energy Star certification. A COP of 3.3 at 47 degrees F reflects strong low-ambient heating performance. Licensed HVAC technicians install this equipment as a complete, factory-matched refrigerant circuit.

This kit is suited for single-zone climate control in residential rooms, server rooms, additions, or light commercial spaces where a ceiling cassette discharge pattern is preferred over a wall-mount or floor-mount indoor unit. The cassette configuration provides 360-degree or multi-directional airflow from a ceiling-recessed position. The included 25-foot line set covers typical single-room installations. The factory-matched indoor and outdoor units are pre-engineered to operate together, reducing field selection errors and ensuring AHRI-certified performance at the rated efficiency.

Compatibility

Kit includes indoor cassette unit 8733962668, outdoor unit 8733962686, and line set 8733951011. These components are factory-matched and intended to be installed as a complete system. Do not mix these components with unverified indoor or outdoor units outside of BOSCH-published system configurations.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Shut off all power at the disconnect before handling electrical connections. The refrigerant circuit is factory pre-charged; field refrigerant handling must comply with applicable EPA regulations and local mechanical codes. Ceiling cassette installations require proper structural support for the indoor unit and condensate drainage planning prior to mounting.
