Outdoor Unit Single-Zone Ductless Crossover Heat Pump Puron Advance R-454B 2.5 Ton 208/230 V 1-Phase 60 Hz 37MUHAQ30AA3

The Outdoor Unit Single-Zone Ductless Crossover Heat Pump Puron Advance R-454B 2.5 Ton 208/230 V 1-Phase 60 Hz (37MUHAQ30AA3) is an inverter-driven outdoor condenser from Bryant engineered to bridge residential and light commercial ductless applications with higher durability and capacity control. Using Puron Advance R-454B refrigerant, this 2.5-ton platform modulates compressor output to closely match load conditions, supporting improved part-load efficiency, quiet operation, and consistent comfort delivery. It operates on 208/230 V single-phase, 60 Hz power. For proper job fit, technicians must verify the selected indoor unit is approved for crossover pairing at the 2.5-ton capacity, confirm refrigerant line sizing and maximum allowable piping lengths per Bryant installation requirements, and ensure the electrical supply meets the unit’s minimum circuit ampacity and overcurrent protection specifications. Correct pairing supports stable operation and reduces callbacks related to capacity mismatch.
