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 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. 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
