Standard Length = 80 ft. (24.4 m) or less total equivalent length
Applications in this area are long line. Accessories are required as shown recommended on Long Line Application Guidelines
Applications in this area may have height restrictions that limit allowable total equivalent length, when outdoor unit is below indoor unit.
— Applications in this area are not recommended due to insufficient oil return.
