Notes:
1) Do not exceed 46 met ers linear line lengt h.
2) Do not exceed 15 met ers vert ical separat ion bet ween indoor and out door unit s.
3) * 19.05mm [3/4 in.] vapor line should only be used for 2 t on syst ems if out door unit is below or at same level as indoor
unit t o assure proper oil ret urn.
4) ** 28.58mm [1-1/8 in.] vapor line should only be used for 5 t on syst ems if out door unit is below or at same level as indoor
unit t o assure proper oil ret urn.
5) Always use the smallest liquid line allowable to minimize refrigerant charge.
6) Applications shaded in light gray indicate capacity multipliers between 0.90 and 0.96 which are not
recommended, but are allowed.
7) Applications shaded in dark gray are not recommended due to excessive liquid or suction pressure drop.
