for standing, laying and tilted installation
- The casing foundation has to be flat and even.
- Above all the weight support of the centre hub needs to be taken into account during planning and erecting the supporting construction.
- The middle traverse of the encasing may not bend through.
- It must be ensured that no additional forces bear on the casing when ducts, chambers, devices and so forth are mounted. Twisting of the encasing has to be avoided.
