Goodman alzs5ba4810 Split Heat Pump 4 Ton 15.2 SEER2 R-32

Product Description

The Goodman alzs5ba4810 is a 4-ton, single-stage outdoor split heat pump designed for residential and light-commercial applications requiring a high-efficiency, non-communicating R-32 refrigerant system. Rated at 15.2 SEER2 and 7.8 HSPF2, this unit delivers 48,000 BTU/h nominal heating capacity and operates on a 208/230-volt, single-phase, 60 Hz power supply. The scroll compressor and top-discharge cabinet are factory pre-charged with R-32 refrigerant. It carries ENERGY STAR certification and meets DOE regional compliance requirements for all U.S. regions. Licensed HVAC technicians install this unit as the outdoor condensing component of a split-system heat pump.

This unit fits residential new-construction and replacement applications where a single-stage, non-communicating outdoor unit is required. The alzs5ba4810 is rated for cooling operation between 55 degrees F and 125 degrees F ambient and heating operation down to -20 degrees F, making it suitable for a wide range of climates. It supports standard line set lengths up to 200 feet horizontal and 79 feet vertical, with a factory refrigerant pre-charge covering the first 15 feet. Components referenced with this unit include 0161R00128, ABK-20, CSR-U-2, CSR-U-3, FSK01A, OT18-60A, and TXV-FX-KX-5T.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification, as this system uses R-32 flammable refrigerant requiring proper handling procedures. Disconnect and lock out all electrical power before making refrigerant or electrical connections; verify minimum circuit ampacity of 28.3 A and a maximum overcurrent protection device of 45 A per NEC requirements. Use the specified liquid line size of 3/8 inch O.D. and suction line of 7/8 inch O.D. valve connections; do not exceed the 200-foot maximum standard line set length. Follow local mechanical and electrical codes and the manufacturer installation instructions for refrigerant line evacuation, leak testing, and startup procedures.
