*NOTES:
1. Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size.
2. All sizes shown are for O.D. Type ”L“ copper tubing.
3. Suction line sizes selected at pressure drop equivalent to 2°F. Reduce estimate of system capacity accordingly.
