All Line Sizes are for O.D. Type L, ACR, or RS copper tube.  All Lengths are "Equivalent Feet."

Shading indicates Maximum Suction Riser Size.  Diameter of riser must not be larger than horizontal run.

All lines selected for 2°F equivalent pressure loss maximum.

Consider double suction risers if capacity control is used.

See page 6 for "equivalent feet" of valves and fittings.

Suction traps must be used for proper oil return.

Liquid line is from receiver to expansion valve.
