Installation details, Basic information and nomenclature

  • Installation details
  • Basic information and nomenclature

Installation and commissioning

  • Splitters are supplied as ready-to-install kits
  • Follow the installation information and comply with the general codes of good practice in order to achieve the given performance data
  • Up to height H = 1200 mm: any installation orientation, but we recommend upright installation of splitters
  • From height H = 1201 mm: upright installation only
  • The length (L) of sound attenuator splitters and splitter sound attenuators refers to the airflow direction; be sure to note how width, height and length are defined, particularly in case of a vertical airflow
  • Installation in ducts outside of closed rooms requires sufficient protection against the effects of weather
