Outdoor Unit Single-Zone Ductless Heat Pump Puron Advance R-454B 1.5 Ton 208/230 V 1-Phase 60 Hz

The Outdoor Unit Single-Zone Ductless Heat Pump Puron Advance R-454B 1.5 Ton 208/230 V 1-Phase 60 Hz (37MARAQ18AA3) is a mid-capacity inverter outdoor condenser in Bryant’s Puron Advance™ line engineered for single-zone cooling and heating with R-454B refrigerant, providing enhanced environmental performance and energy efficiency. This 1.5 Ton platform modulates compressor speed to match varying load conditions, improving part-load efficiency and maintaining quiet operation. It is ideal for residential applications in moderate climates when paired with a correctly sized indoor fan coil or air handler. For proper job fit, technicians must verify that the selected indoor unit matches the outdoor 1.5 Ton capacity, confirm proper refrigerant line sizing and allowable piping lengths, and ensure a dedicated 208/230 V single-phase, 60 Hz electrical supply with correctly sized overcurrent protection and disconnect is present. Correct system pairing supports efficient comfort delivery and consistent performance across operating conditions.
