The Outdoor Unit Single-Zone Ductless Heat Pump Puron Advance R-454B 2 Ton 208/230 V 1-Phase 60 Hz (37MAHAQ24AA3) is a robust single-zone inverter heat pump designed for year-round comfort using Bryant’s Evolution™ 37MAHA series with Puron Advance™ (R-454B) refrigerant, engineered to provide high cooling efficiency (up to ~27.5 SEER2) and strong heating performance (up to ~14.8 HSPF2) when matched with the correct indoor unit. This unit operates on 208/230 V single-phase, 60 Hz power and supports balanced cooling and heating across moderate climates with quiet outdoor operation down to ~-23 °F and heating up to ~122 °F outdoor ranges. It includes inverter modulated compressor technology and a built-in basepan heater for improved low-ambient reliability. For proper job fit, technicians must verify that the selected indoor fan coil matches the outdoor capacity and Puron Advance refrigerant type, confirm correct refrigerant line sizing and allowable piping distances, and ensure proper 208/230 V single-phase power with correctly sized overcurrent protection and disconnect. Correct pairing helps ensure stable comfort performance, peak seasonal efficiency, and compliance with Bryant’s environmental and warranty standards.
