VAPOR LINE SIZING 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
or when there is more than 20 Ft 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
250Ft. The maximum vertical separation is 200 Ft when outdoor
unit is above indoor unit, and 60 Ft when the outdoor unit is
below the indoor unit. Refer to Accessory Usage Guideline below
for required accessories. See Long--Line 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 or less total equivalvent 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
