Refrigerant line routing

6.1

Precautions

Take precautions to prevent noise within the building structure due to
vibration transmission from the refrigerant lines. For Example:

When the refrigerant lines have to be fastened to floor joists or
other framing in a structure, use isolation type hangers.

Isolation hangers should also be used when refrigerant lines are
run in stud spaces or enclosed ceilings.

Where the refrigerant lines run through a wall or sill, they should
be insulated and isolated.

Isolate the lines from all ductwork.

Minimize the number of 90º turns.
