Notes:
1) Do not exceed 46 meters linear line length.
2) *Do not exceed 15 meters ver
ti cal separa ti on between indoor and outdoor units if the indoor unit is above the indoor unit.
3) ** 19.05mm [3/4 in.] vapor line should only be used for 2 ton systems if outdoor unit is below or at same level as indoor
unit to assure proper oil return.
4) Always use the smallest liquid line allowable to minimize refrigerant charge.
5) Applica
ti ons shaded in light gray indicate capacity mul ti pliers between 0.90 and 0.96 which are not
recommended, but are allowed.
