4LONG LINE APPLICATIONSAn application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptablerefrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long linedepends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.For Air Conditioner systems, the chart below shows when an application is considered Long Line.AC WITH PURONr REFRIGERANT LONG LINE DESCRIPTION ft (m)Beyond these lengths, long line accessories are requiredLiquid Line Size Units On Same Level Outdoor Below Indoor Outdoor Above Indoor1/4 No accessories needed within allowedlengthsNo accessories needed within allowedlengths 175 (53.3)5/16 120 (36.6) 50 (15.2) vertical or 120 (36.6) total 120 (36.6)3/8 80 (24.4) 35 (10.7) vertical or 80 24.4) total 80 (24.4)Note: See Long Line Guideline for detailsVAPOR LINE SIZING AND COOLING CAPACITY LOSSAcceptable vapor line diameters provide adequate oil return to the compressor while avoiding excessive capacity loss.
