*Requires a double suction riser if 2 unloaders are used and the evaporator is below the condensing unit. See Refrigerant Piping Sizes — Double Suction Ris- ers table and Suction Line Piping figure below for more information.

NOTES:

1.Pipe sizes are based on a 2° F loss for liquid lines and a 1.5° F loss for suc- tion lines.

2.Pipe sizes are based on an equivalent length equal to the maximum length of interconnecting piping plus 50% for fittings. A more accurate estimate may result in smaller sizes.
