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.
