1560-480 Compressor ZPV0802E-4X9 Scroll is the factory-fitted 3-phase Inverter Scroll compressor (ZPV0802E-4X9-550) for Advance R32 and AIRES variable-speed residential split ducted systems, compressing R410A refrigerant to drive the system's heating and cooling cycle at the heart of the outdoor unit. A failed compressor causes complete system shutdown with loss of variable-speed capacity modulation -- the system cannot heat or cool until a replacement is installed. Isolate power and recover all refrigerant before replacement -- compressor replacement must be performed by an ARCtick-licensed refrigeration technician.
