The Outdoor Unit Single-Zone Ductless Crossover Heat Pump Puron Advance R-454B 3 Ton 208/230 V 1-Phase 60 Hz (37MUHAQ36AA3) is a high-capacity crossover inverter outdoor unit designed for single-zone applications requiring increased heating and cooling output beyond standard residential models. This 3-ton system uses inverter compressor modulation and R-454B refrigerant to deliver stable capacity control, improved seasonal efficiency, and reduced sound levels across varying load conditions. It runs on 208/230 V single-phase, 60 Hz electrical service. For proper job fit, technicians must confirm indoor unit compatibility and correct capacity match, verify refrigerant line sizes and allowable run lengths, and ensure the electrical service meets Bryant-published MCA and MOCP requirements with appropriate disconnect and grounding. Proper application supports dependable comfort and long-term system reliability in higher-demand environments.
