Maximum Line Set Length and Height Specications*
* The table above represents the maximum length and height that the refrigerant line sets can be for each
system based on its respective capacity. In order to achieve some of these lengths, line set coupler kits and
additional line sets must be used (not included, sold separately). Any attempt to increase the line set length
beyond what is specified in the table above, could result in reduced heating/cooling performance, system
damage or failure, and WILL VOID THE WARRANTY.
