The Outdoor Unit Single-Zone Ductless Heat Pump Puron Advance R-454B 2.75 Ton 208/230 V 1-Phase 60 Hz (37MAHAQ33AA3) is a high-capacity single-zone outdoor condenser in Bryant’s Evolution™ 37MAHA product family, utilizing Puron Advance™ (R-454B) refrigerant for enhanced environmental performance and into-season comfort. Designed for systems requiring elevated load capacity, this unit modulates output with a variable-speed compressor for efficient cooling and heating while maintaining quiet operation across its operating range. It runs on 208/230 V single-phase, 60 Hz power and, when paired with a properly sized indoor fan coil, delivers balanced comfort in homes or larger spaces. For proper job fit, technicians must verify indoor unit capacity and compatibility, confirm correct refrigerant piping size and maximum allowable length, and ensure the required 208/230 V single-phase electrical service with correct minimum circuit ampacity and overcurrent protection. Accurate pairing according to Bryant pairing charts ensures effective capacity delivery and system reliability.
