5. Drill the pilot holes. (Skip this step if the surface is wood.)
Due to the expansion and contraction of vinyl and aluminum siding during
changes in temperature most manufacturers recommend drilling mount-
ing holes larger than the screw or bolt diameter. Please consult the siding
manufacturer for specific information. Do not over tighten the lag screws
on vinyl siding since this prevents free movement when expansion
occurs.
When installing the chassis on vinyl or aluminum siding, drill the manufac-
turer’s recommended oversize hole in the siding before drilling the pilot
hole in the material under the siding. For brick or concrete block installa-
tion, follow the recommendations of the anchor manufacturer, and insert
each anchor flush with the wall surface.
6. Secure the wall bracket to the surface using the washers and lag screws.
7. Tighten the screws securely, but do not over-tighten the screws because it
can cause damage to the surface.
