• OLR/ÖLS [b]: The product is made of sheet steel, powder-coated in white RAL standard color, internally insulated with washable and surface-coated sound absorber. The product's insulation consists of 100% recycled, non-allergenic, hydrophobic PET plastic material. It is free from formaldehyde and, when burned, only carbon dioxide and water are produced.

• RAM-OLS/ÖLS [b₂]:: Mounting frame, made of hot-dip galvanized sheet steel.

• OFI-C: Made from environmentally friendly, flame-retardant polyurethane foam. The material is CertiPUR and Oeko-Tex certified.

• The product is installed in pairs with the supplied mounting frames on either side of a wall over a rectangular holecutting.

• The inner dimensions of the included mounting frames can be used as a cutting template.

• Each frame is marked with a centred arrow cut-out. The frames must be installed with the arrow pointing upwards for correct wall mounting.

• The frame parts have pre-drilled holes for screw mounting. Each frame is secured with screws (not included).

• For a single plasterboard wall, a screw at least 20 mm long is recommended; for a double plasterboard wall, at least 30 mm.

• Each front panel is then hooked onto the mounting frame brackets for final installation.

• When fibre protection sleeve OFI-C / ÖFI-C is used, the protection sleeve should ideally be inserted into the cut-out before installing the transfer unit and mounting frame.

• The fibre protection cover can, however, be installed either before or after installation of the transfer unit. The sleeve penetration's elastic and self-tensioning properties make it easy to press into the hole in the stud wall.
