Outdoor Unit Multi-Zone Ductless Heat Pump Standard R-454B 30,000 BTU 4-Port 208/230 V 1-Phase 60 Hz

The Outdoor Unit Multi-Zone Ductless Heat Pump Standard R-454B 30,000 BTU 4-Port 208/230 V 1-Phase 60 Hz (MIT-MXZ4D30NL) is a variable-speed inverter outdoor condenser designed for four-zone ductless systems requiring balanced cooling and standard heating performance. This unit uses an inverter-driven compressor with linear expansion control to dynamically match capacity to zone demand while maintaining quiet operation and strong part-load efficiency. It operates on 208/230 V single-phase 60 Hz power and supports a wide range of compatible M-Series indoor units when applied within published capacity limits. For proper job fit, technicians must verify total connected indoor capacity, confirm refrigerant line sizing and maximum allowable piping lengths, and ensure the electrical service meets MCA and MOCP specifications. Correct application prevents capacity overload, communication faults, and unnecessary service callbacks.
