VAPOR LINE SIZING AND COOLING CAPACITY LOSS
PURON 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 250
ft. The maximum vertical separation is 200 ft. when outdoor unit
is above indoor unit, and 80 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 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
