the vent opening. See figure 46 below. Drill the holes in the groove formed where the adapter meets the mullion. The holes should penetrate the adapter,
the isolator, and the first wall of the mullion where the isolator is seated. See Figure 47 below. Ensure the adapter is properly positioned and seated into the
isolator before drilling.
