VAPOR LINE SIZING AND COOLING CAPACITY LOSS
PURON 1--STAGE AIR CONDITIONER 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 80
ft. when the outdoor unit is below the indoor unit. Refer to
Accessory Usage Guideline 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 Guideline
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 Guideline.
