Condensing Unit Refrigerant Line Size Information

NOTES:

1. Do not exceed 200 ft linear line length.

2. *Do not exceed 100 ft vertical separation if outdoor unit is above indoor unit.

3. **

3/4" suction line should only be used for 1.5 ton systems if outdoor unit is below or at same level as indoor to assure proper

oil return.

4. Always use the smallest liquid line allowable to minimize refrigerant charge.

Applications shaded in light gray indicate capacity multipliers between 0.90 and 0.96 which are not recommended,

but are allowed.

Applications shaded in dark gray are not recommended due to excessive liquid or suction pressure drop.
