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.
