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 (197 ft), height limits (49.21 ft), and required electrical protection (MCA 24.5A, max fuse 30A). Refrigerant is R410A with factory precharge up to 75 ft; additional charge may be required beyond that length.
