Installation Steps

Set out the carrier lines and finished panel face from the design drawings.
Choose the installation direction and install the main and secondary square-steel framing to the panel grid. Check that the supporting face is flat.
Follow the installation sequence shown: left to right and bottom to top. Insert each left-hand bracket between the adjacent panel return and the supporting frame. Fix the right-hand and upper brackets with countersunk self-drilling screws.
Keep hands clean during installation. Avoid sweat, oil and other contamination on the finished surface.

Installation Steps

Set out the carrier lines and finished panel face from the design drawings.
Choose the installation direction and install the main and secondary square-steel framing to the panel grid. Check that the supporting face is flat.
Set the support fittings on the framing to match the panel-hook positions, then hang the panels onto those fittings.
Keep hands clean during installation. Avoid sweat, oil and other contamination on the finished surface.

These system details explain the illustrated assembly. Anchor selection, structural capacity and final suspension spacing must follow the approved project drawings and local requirements. Different carrier configurations are not interchangeable.
