Humidex
10
minimum unit height of 62 inches. For extra high ceilings, an extension piece of 24 inches is available
which can be added at the top of the unit.
When ducting the unit outside, no more than 3 feet of Vinyl Flex should be used. When circumstances
require a longer span, rigid ducting can be used from the inside of the unit to the wall. The rigid duct
will improve the airflow to compensate for the additional distance the air has to flow to reach the
outside.
When replacing a pane for a window installation, use pressurized wood or similar water/rot proof
material.
Make sure that no pipes, studs or wires are in the way.
The duct has to be dedicated and not combined with any other existing ductwork in operation. Seal
well around the outside opening.
Installation
Factors to consider
The installation must be done in the basement or the lowest, dampest, coldest level of your dwelling.
Try to find an outside wall to accommodate a 6¼” hole to the exterior of the house where no
electrical wires or pipes are present. The unit should be installed with a minimum distance of 8 feet
from any source of heat
. Make sure that you do not install the unit in a boiler room.
It is important to maximize the distance between the unit and the source of replenishment air (example:
stairwell or openings to upper level).
For an interior wall installation: The distance between the Humidex back and the exterior wall should
not be more than 12 feet. For this application the flex has to be replaced with rigid piping. Optional:
The bottom cap may be removed for added airflow.
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’s
location is above ground level. Also make sure that the hole doesn’t line up with a stud, electrical
wires, or pipe.
