Outdoor Unit Single-Zone Ductless Heat Pump QuietComfort Series Inverter R-454B 9,000 BTU 208/230 V 1-Phase 60 Hz D5CSRAH09AAK

The Outdoor Unit Single-Zone Ductless Heat Pump QuietComfort Series Inverter R-454B 9,000 BTU 208/230 V 1-Phase 60 Hz (D5CSRAH09AAK) is an inverter-driven outdoor condenser designed for compact single-zone applications requiring quiet operation and efficient year-round heating and cooling. Rated at 9,000 BTU (0.75 ton), this unit uses R-454B refrigerant and variable-speed modulation to closely match load conditions, supporting stable temperature control and reduced sound levels. It operates on 208/230 V single-phase, 60 Hz power. For proper job fit, technicians must verify approved indoor unit pairing at 9K capacity, confirm refrigerant line sizing and allowable piping lengths per system requirements, and ensure the electrical service meets published MCA and MOCP values. Correct matching minimizes short-cycling and supports reliable long-term performance.
