Outdoor Unit Single-Zone Ductless Heat Pump Puron Advance R-454B 3 Ton 208/230 V 1-Phase 60 Hz 37MARAQ36AA3

The Outdoor Unit Single-Zone Ductless Heat Pump Puron Advance R-454B 3 Ton 208/230 V 1-Phase 60 Hz (37MARAQ36AA3) is a high-capacity inverter outdoor condenser from Bryant designed to deliver efficient year-round cooling and heating for a single indoor zone using Puron Advance™ (R-454B) refrigerant, an environmentally advanced, lower-GWP formulation. Bryant ductless systems matched with properly sized indoor fan coils can deliver premium seasonal efficiency — up to ~27.5 SEER2 cooling and ~14.8 HSPF2 heating — and are suitable for moderate climates when paired per published pairing charts. For proper job fit, technicians must confirm the indoor fan coil is correctly sized for a 3 Ton system, verify proper 208/230 V single-phase, 60 Hz electrical service with appropriate minimum circuit ampacity and overcurrent protection, check refrigerant line size and allowable run length per Bryant’s installation documentation, and confirm clearances and support for outdoor placement. Correct pairing ensures balanced comfort delivery and aligns with Bryant’s performance and warranty standards.
