Notes:
1) Do not exceed 61 meters linear line length.
2) Do not exceed 30 meters verƟcal separaƟon between indoor and outdoor units.
3) * 19.05 mm [3/4 in.] vapor line should only be used for 1.5 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 refrigera
nt charge.
5) ApplicaƟons shaded in light gray indicate capacity mulƟpliers between 0.90 and 0.96 which are not recommended, but are allowed.
6) ApplicaƟons shaded in dark gray are not recommended due to excessive liquid or sucƟon line pressure drop.
