5. Refrigerant Pipe Routing
Comply with National, State, and Local Codes when isolating pipe sets from joists, rafters, walls, or
other structural elements.
Take precautions to prevent noise within the building structure due to
vibration transmission from the refrigerant pipes. For Example:
•
Use isolation type hangers when the refrigerant pipes have to be fastened to floor joists or other framing.
•
Isolation hangers should also be used when refrigerant pipes traverse stud spaces or enclosed ceilings.
•
Where the refrigerant pipes pass through a wall or sill, it should be insulated and isolated.
•
Isolate the pipes from all ductwork.
•
Minimize the number of 90
