Alternatively, on the main page, click Edit file and either Add section(s) to initiate sections for editing, or Add after to add further sections to the file. Click Edit Duct to change flowrate, duct size and material. Index resistance files It is recommended to add and size duct sections before entering fitting data. This will ensure that the displayed loss coefficients for each fitting are correct. Duct sections should be entered in the order of flow, i.e., from supply fan to supply grille or from extract grille to extract fan. To add sections to a file, click Add to system on the Duct List or Duct Data pages. Alternatively, on the main page, click Edit system and either Add section(s) to initiate sections for editing, or Add after to add further sections to the file. Click Edit duct data to change flowrate, duct size and material. Click Edit index data to add or change fittings. Click System pressure loss to calculate and display the system resistance and Create pdf if required.
