Remarks • Stainless steel and aluminium are both based on natural raw mate- rials. When rolling and polishing steel/anodizing aluminium, small hair-line irregularities can occur in the surface. These are the result of the normal machining process and do not constitute material faults. • The installation cable must be laid without tension, kinking or torsion. • Do not fasten the screws with excessive tightening torque! If a bat- tery-driven screwdriver is used, the torque must be limited to < 1.5 Nm.
