Installation HCS-APT/HCS-APTHC
Selecting the Duct Location
Now that you’ve decided where to install the unit, you must select a location for a 6¼” duct hole in
the outside wall. This hole is needed to pass a duct through the outside wall. Make sure that the hole
doesn’t line up with a stud, electrical wires, or pipe.
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.
