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.
