Mitsubishi Electric mxz-sm48nlhz-u1 48000 Btu Multi Zone Outdoor Unit

Product Description

The MITSUBISHI ELECTRIC mxz-sm48nlhz-u1 is a 48,000 BTU/h smart multi-zone hyper heat outdoor condensing unit designed for variable-capacity, multi-zone heating and cooling applications. It uses an INVERTER-driven compressor to modulate capacity continuously, matching actual load demand rather than cycling on and off at fixed output. The unit operates on R454B refrigerant and delivers a thermal differential of 1 degree F for precise temperature control. Licensed HVAC technicians install and commission this unit as part of a larger split system serving multiple indoor zones simultaneously.

This outdoor unit is suited for residential and light commercial multi-zone applications where a single outdoor unit must serve several interior spaces independently. It is compatible with M-Series and P-Series indoor units as well as CITY MULTI indoor units, with a branch box required when connecting M-Series or P-Series equipment. Its hyper heat design maintains heating capacity at low ambient outdoor temperatures, making it appropriate for cold-climate installations where conventional equipment falls short.

Key Features

• INVERTER-driven compressor delivers precise capacity to maintain set-point temperature and reduce energy swings
• Thermal differential of 1 degree F for accurate zone temperature management
• Seacoast protection on heat exchanger and base panel, rated for 2,000 hours per ASTM B117 salt-spray testing
• Quiet outdoor operation at conversational noise levels; most paired indoor units are whisper quiet
• Compressor overcurrent detection and thermal protection for reliable fault response
• High pressure protection and fan motor overheating/voltage protection for system safety

Compatibility

Compatible with M-Series and P-Series indoor units and CITY MULTI indoor units; a branch box is required for connection with M-Series and P-Series indoor units.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with applicable local mechanical codes and the manufacturer documentation. Disconnect and lock out all electrical power to the system before beginning any service or connection work. R454B is an A2L mildly flammable refrigerant; follow all applicable refrigerant handling regulations and ensure adequate ventilation during service. Verify that the branch box is installed and wired correctly before commissioning the indoor units.
