NOTES:

1. Do not exceed 150 ft linear line length.
2. Do not exceed 50 ft vertical separation between indoor and outdoor units.
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. **1-1/8″ vapor line should only be used for 5 ton systems if outdoor unit is below or at same level as indoor unit to assure proper oil return.
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.
