and forming of the tubing is complete. See the
Coupling Instructions for final connections.

Both ends of each line are designed for field

listed in the next step, are the minimum sizes
recommended for passing the refrigerant lines
through.

the refrigerant lines of 2". Check local codes, a
separate hole may be required for the electrical
power supply to the condenser.
Caution: Do NOT kink the refrigerant tubing while
