VAPOR LINE SIZING AND COOLING CAPACITY LOSS

Acceptable vapor line diameters provide adequate oil return to the compressor while avoiding excessive capacity loss. The suction line
diameters shown in the chart below are acceptable for HP systems with Puron refrigerant:

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 See Long Line Applica-
tion Guidelines
