VAPOR L INE SIZ I NG AND COOLING CAPACITY LOSS
1--STAGE HEAT PUMP APPLICATIONS
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 250
ft. (76.2 m). The maximum vertical separation is 200 ft. (60.96 m)
when outdoor unit is above indoor unit, and 60 ft. (18.29 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 acceptable
vapor tube diameters based on the total length to minimize the
cooling capacity loss.

Standard Length = 80 ft. (24.38 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 Application Guidelines
