VAPOR LINE SIZING AND COOLING CAPACITY LOSS

PURON 1-STAGE HEAT PUMP APPLICATIONS

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

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
