Position and alignment of air dampers for X2000
The base is comprised of air dampers and four leveling units which are suitable for screed floors as per DIN 18560. The
air dampers and leveling unit are only placed on the foundation (floor) as shown in the illustration.
If the quality specified in DIN 18560 is not guaranteed or the foundation is in poor condition, then the enclosed
spacer plates (1 or 3 mm thick) are required.
