Adjusting the slider position
Like all standard units, the height of the supply air module
is adjusted using the threaded rods and connected by the in-
stallation brackets to the substrate. The slider can be moved
into different positions to adjust the required volumetric
flow at the supply air module. The drawing on the left
shows 4 different slider positions (100%, 75%, 50% and 30%
opened). They are also shown in the design diagrams below
in which the pressure losses, sound levels and airflows can be
seen. Intermediate values can be interpolated.
