1560-402 Copeland Compressor ZR125KC-TFD-522 Scroll is the factory-fitted Scroll compressor for Classic Series R22 residential and commercial split ducted systems, using Copeland Scroll technology (ZR125KC-TFD-522) for reliable fixed-speed R22 operation to compress R22 refrigerant and drive the system's cooling and heating cycle. A failed compressor causes complete system shutdown -- R22 refrigerant recovery is required before any compressor replacement work. When replacing this compressor, ActronAir recommends also replacing the compressor contactor -- both components are stressed equally during the fault event that caused compressor failure. Isolate power and recover all refrigerant before replacement -- compressor replacement must be performed by an ARCtick-licensed refrigeration technician.
