• Depending on the transducer type, it can be necessary to install additional layers of damping mats (see Technical Spec-
ification, annex Damping mats). Repeat the steps for the installation of the damping mat.
• When mounting the transducer, make sure not to mount the transducers on the seams between the damping mats. If the
transducers are mounted on the seams, there must be no gaps between the damping mats under the transducers, this
means the damping mats must be installed edge to edge.
