*Units are rated with 25 ft (7.6 m) of lineset length. See
Vapor Line Sizing and Cooling Capacity Loss
table when using other sizes and lengths of lineset.
Note
: See unit Installation Instruction for proper installation.
VAPOR LINE SIZING AND COOLING CAPACITY LOSS
Acceptable vapor line diameters provide adequate oil return to the compressor while avoiding excessive capacity loss. The suction line
diameters shown in the chart below are acceptable for HP systems with Puron refrigerant:
