Drill four 12 mm diameter holes using the mount base as a template or following
the drawing below to a depth of 77 mm.
Figure 7-7. Mounting footprint
Clean the holes of all debris.
Place washers and nuts on the ends of the wedge anchors supplied (to protect the
threads during installation).
Hammer the wedge anchors into the holes until the start of the threads are below
the surface.
Tighten the nuts until about 25 mm of thread protrudes above the surface.
Remove the washers and nuts from the protruding length screw. Then lower the
mount into place.
Finally secure the mount with the washers and nuts.
If the surface is not level and flat it may be necessary to add washers under the
base on one or more of the foundation screws.
