Duct installation
- The bend radius of the ducts must be 20 times their outside diameter.
- The ducts are assembled together according to the pulling direction
- A gauge of the appropriate diameter must be passed through the ducts (0.8 times the inside diameter of the duct). The ducts must be gauged and closed.
- It is recommended to use tube supports to ensure the correct
distance between the ducts (the distance between the “teeth” of the tube support is 10 times the outside diameter of the duct).
