ESI Outdoor Unit Installation Instruction

5. Refrigerant Line Routing

Comply with National, State, and Local Codes when isolating line 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 lines. For Example:
• Use isolation type hangers when the refrigerant lines have to be fastened to floor joists or other framing.
• Isolation hangers should also be used when refrigerant lines traverse stud spaces or enclosed ceilings.
• Where the refrigerant lines pass through a wall or sill, it should be insulated and isolated.
• Isolate the lines from all ductwork.
• Minimize the number of 90º turns.
