Drill a hole to the required depth using a stop drill bit matched to the anchor. Refer to TABLE 4B of this
report. Position fixture so that the fixture bears fully on the concrete surface without a gap between the
fixture and concrete, and so that the fixture hole is centered over the drilled hole in the concrete.
2 Remove the drilling debris from the hole using a vacuum, compressed air or a hand air pump.

The anchor is placed to the bottom of the hole by hand. Do not strike with a hammer. Do not remove the
plastic cap. This cap protects the threading during installation.

setting operation. See pictogram 5.
