Notes:
1) Do not exceed 150  linear line length.
2) *Do not exceed 50  vercal separaon between indoor and outdoor units if the outdoor unit is above the indoor unit.
3) ** 3/4" 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ons shaded in light gray indicate
capacity mulpliers between 0.90 and 0.96 which are not
recommended, but are allowed.
6) Applicaons shaded in dark gray are not recommended due to excessive liquid or sucon pressure drop.
