Important
Install with a licensed HVAC professional. This is a multi-zone outdoor condenser intended to be matched with compatible indoor units. Confirm match-ups, total connected indoor capacity, and piping design before ordering. Observe maximum total piping (131 ft), height limits (49.21 ft), and required electrical protection (MCA 18A, max fuse 25A). Refrigerant is R410A with factory precharge up to 50 ft; additional charge may be required beyond that length.
