VAPOR LINE SIZING AND COOLING CAPACITY LOSS

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