Preparing the Humidex for Installation
Now that an installation location has been chosen a hole must be made for the vent.
Start by measuring the required Unit height and mark the location of the hole.
Remember that the units cannot be higher than 3” to 6” off the ground.
From the inside, drill a pilot
hole of approximately ¼”
wide at the center of the
proposed 6¼” hole.
Outside the building, find the
pilot hole.
Now 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.
