For reference to connected capacity charts, please refer to Multi-zone Outdoor Unit Oper- ational Performance. For actual capacity performance based on indoor unit type and number of indoor units connected, please refer to MXZ Operational Performance. Although the maximum connectable capacity is 130%, the outdoor unit cannot provide more than 100% of the rated capacity. Please utilize this over capacity capability for load shedding or applications where it is known that all connected units will NOT be operating at the same time. * Indoor/Outdoor Unit Operating Temperature Range (Cooling Air Temp [Maximum / Minimum]): • Applications should be restricted to comfort cooling only; equipment cooling applications are not recommended for low ambient temperature conditions. ** Outdoor Unit Operating Temperature Range (Cooling Thermal Lock-out / Re-start Temperatures; Heating Thermal Lock-out / Re-start Temperatures): • System cuts out in heating mode and automatically restarts at these temperatures. GENERAL FEATURES • INVERTER-driven compressor: An inverter-driven compressor generates the precise capacity needed to maintain a temperature set point. • Thermal Differential 1°F • Seacoast protection: Seacoast protection on heat exchanger and base panel (rated for 2,000 hrs. in accordance with ASTM B117 testing) • Quiet operation: Outdoor units are as quiet as a typical conversation, and most indoor units are whisper quiet. • Hyper-Heating INVERTER®: Hyper-heating performance offers 100% heating capacity at 5°F and 75% heating capacity at -13°F • Fan motor overheating/voltage protection • Compressor thermal protection • Compressor overcurrent detection • Built-in base pan heater • High pressure protection Specifications System Unit Type MXZ-3D24NLHZ Outdoor Unit Fan Motor Full Load Amperage A 1.74 Fan Motor Output W 88 Defrost Method Reverse Cycle Blue Fin Heat Exchanger Coating Yes Airflow Rate Cooling/Heating CFM 2,239 / 2,378 Sound Pressure Level, Cooling1 dB (A)56 Sound Pressure Level, Heating2 dB (A)58 Compressor Type Twin Rotary Compressor Model SRB280FDRMC Compressor Oil Type // Charge Type // oz RM68EH // 23.7 External Finish Color Munsell 3.0Y 7.8/1.1 Base Pan Heater Built-in Unit Dimensions (W x D x H)inch x inch x inch [mm x mm x mm]37-13/32 x 13 x 31-11/32 [950 x 330 x 796] Package Dimensions (W x D x H)inch x inch x inch [mm x mm x mm]41-11/32 x 17-5/16 x 38-31/32 [1,050 x 440 x 990] Unit Weight lbs [kg]152 [69] Package Weight lbs [kg]178 [81] ODU Operating Temp.
