VAPOR LINE SIZING AND COOLING CAPACITY LOSS

LONG LINE APPLICATION: An application is considered ”Long	when outdoor unit is above indoor unit, and 60 ft. (18.28 m) when
line” when the total equivalent tubing length exceeds 80 ft. (24.38	the outdoor unit is below the indoor unit. Refer to Accessory
m) or when there is more than 20 ft. (6.09 m) vertical separation	Usage Guideline below for required accessories. See Longline
between indoor and outdoor units. These applications require	Application Guideline for required piping and system
additional accessories and system modifications for reliable system	modifications. Also, refer to the table below for vapor tube
operation. The maximum allowable total equivalent length is 250	diameters based on the total length to minimize the cooling
ft. (76.2 m). The maximum vertical separation is 200 ft. (60.96 m)	capacity loss.

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
