Bosch 8733980410 Single-zone Mini-split Kit 18000 Btu/h

Product Description

The BOSCH 8733980410 is a single-zone mini-split system kit rated at 18000 BTU/h, designed for ductless heating and cooling in residential and light-commercial applications. Operating on 230 volts, this Generation 4 kit achieves a SEER2 rating of 21.4 and an HSPF2 of 11.0, placing it firmly in the high-efficiency tier and meeting Energy Star criteria. The kit ships as a complete package including an indoor unit, an outdoor unit, and a 16-foot line set, reducing the number of separate line items a technician needs to source. Licensed HVAC technicians perform the installation, covering refrigerant line connections, low-voltage wiring, and electrical rough-in.

This kit targets single-zone ductless applications where a full mini-split system needs to be installed in one order. Typical scenarios include additions, converted spaces, server rooms, garages, and any conditioned zone that lacks existing ductwork. The included 16-foot line set covers standard wall-penetration installations where the indoor and outdoor units are on adjacent or nearby walls. The system is suited for both new construction and retrofit projects where a high-efficiency, inverter-driven mini-split is specified.

Compatibility

Kit includes indoor unit 8733962674, outdoor unit 8733962690, and line set 8733951017. These components are matched and rated together as a single AHRI-certified system at 18000 BTU/h.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician, as the system contains refrigerant and requires proper handling per applicable regulations. Disconnect and lock out all electrical power at the panel before making any wiring connections. Route the line set through the wall penetration, verify all flare connections are properly seated, and follow the manufacturer sequence for startup and leak testing. Local electrical codes apply to the 230-volt circuit, disconnect, and overcurrent protection requirements.
