VAPOR LINE SIZING AND COOLING CAPACITY LOSS

LONG LINE APPLICATION: An application is considered
"Long line" when the total equivalent tubing length exceeds 80
ft. (24.38 m) or when there is more than 20 ft. (6.09 m) vertical
separation between indoor and outdoor units. These applications
require additional accessories and system modifications for
reliable system operation. The maximum allowable total
equivalent length is up to 250 ft. (76.2 m). The maximum

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

vertical separation is 200 ft. (60.96 m) when outdoor unit is
above indoor unit, and up to 80 ft. (24.38 m) when the outdoor
unit is below the indoor unit. Refer to Accessory Usage Guideline
below for required accessories. See Longline Application
Guideline for required piping and system modifications. Also,
refer to the table below for the vapor tube diameters based on the
total length to minimize the cooling capacity loss.
