Outdoor Unit Single-Zone Light Commercial Ductless Heat Pump Puron Advance R-454B 4 Ton 208/230 V 1-Phase 60 Hz 37MBRAQ48AA3

The Outdoor Unit Single-Zone Light Commercial Ductless Heat Pump Puron Advance R-454B 4 Ton 208/230 V 1-Phase 60 Hz (37MBRAQ48AA3) is a high-capacity inverter outdoor condenser intended for single-zone systems in light commercial or larger residential spaces, using Bryant’s Puron Advance™ (R-454B) refrigerant for reduced environmental impact. This 4 Ton unit modulates compressor speed to adapt output to load conditions for efficient cooling and heating delivery, and operates on 208/230 V single-phase, 60 Hz power. For proper job fit, technicians must verify that the selected indoor fan coil matches the 4 Ton capacity, confirm correct refrigerant line size and allowable piping length per Bryant’s installation specifications, and ensure an appropriately sized electrical supply with correct overcurrent protection and disconnect. Correct pairing helps ensure efficient operation and reduces the likelihood of capacity or performance issues in high-demand installations.
