Preparing the CCC-103E for Installation
Measure the required Unit height. Remember that the units cannot be higher than 3"
to 6" off the ground.
From the inside, drill a pilot hole
of approximately ¼" at the
center of the proposed 6¼"
hole.
Outside the building, find the
pilot hole. Using a hole-saw,
with the pilot hole as a guide,
drill a 6¼" hole.
Brick or Concrete Wall: There are two ways of going through brick or concrete. The
first method consists of using a hammer drill. Make holes (approximately 5/8") with
the hammer drill 1" apart through the brick in a circular shape outlining the 6 ¼" hole.
Finish cutting the outer edge of the hole using a chisel. If a hammer drill is not
available, a chisel can be used. As brick is brittle chiseling from the center of the pilot
hole will chip the brick easily. Continue chiseling until you reach the outer edge of the
6 ¼" hole.
