Outdoor Single-Zone Ductless Hyper-Heat Plus Heat Pump with Base Pan Heater 18,000 BTU 208/230 V 1-Phase 60 Hz MIT-MUZFS18NAH

The Outdoor Single-Zone Ductless Hyper-Heat Plus Heat Pump with Base Pan Heater 18,000 BTU 208/230 V 1-Phase 60 Hz (MIT-MUZFS18NAH) is a cold-climate outdoor unit engineered to sustain heating output at low outdoor temperatures while providing efficient cooling. Rated at 18,000 BTU (1.5 ton), this Hyper-Heat Plus configuration uses inverter modulation for precise load matching, quieter operation, and improved part-load efficiency. The integrated base pan heater helps manage ice during defrost and supports reliable drainage in freezing conditions. For proper job fit, technicians must verify approved indoor unit pairing at 18K, confirm refrigerant line sizing and allowable piping lengths, ensure electrical service meets published MCA and MOCP values, and verify outdoor placement and clearances for airflow and snow management.
