6 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.
