Warning!!!
Combustion Appliance Present in Dwelling
Read this Section Carefully
With the presence of appliances evacuating air outside the building envelope (such as range hood,
bathroom fan, dryer, Humidex, etc.) a negative pressure could be created inside the building. As the
pressure inside the building gets lower than the barometric pressure outside, the smoke and gases
from any combustion appliance (oil furnace, gas/wood stove, fireplace, etc.) may be drawn into
the building rather than go out the chimney.
This problem is usually curable by introducing make-up air inside the building. A fresh air kit (Air
Supply Ventilator) is available from your Humidex dealer, to help relieve the effects of negative air
pressure in the building.

Installation
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS,
OBERSVE THE FOLLOWING:
-Installation work and electrical wiring must be done by qualified person(s) in accordance with
all applicable codes and standards, including fire-rated construction.
-When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden
utilities.
-Ducted fans must always be vented to the outdoors.
-For exhaust fans, the discharge air is to be directed to the building exterior.
Ideal installation location
To determine the best location, examine the dwelling for an outside wall where you could install the
HCS-APT or HCS-APTHC. This location should be as far as possible from sources of
replenishment air such as windows, hallways and doors. Try to find a location where no electrical
wires or pipes are present inside the wall. The unit has to be installed on an outside wall.
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 Location 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.

Mounting and installing the unit
Remove the 4 White Screws on the Side of the
Unit. (These are along the back edge of the unit
and are holding the Back Piece)
Separate the Front Aluminum Piece from the
back Galvanized piece.
Place the Unit at its chosen location. Now scribe
the four holes on the wall where the rubber
grommets are installed. Remove the machine and
drill four 1/4" holes where previously scribed.
Apply anchors in the holes using a hammer.

With the help of a tie wrap attach the flex pipe to
the collar on the back of the unit before attaching
the unit to the wall. Insert the other end of the
flex pipe inside the hole in the wall.
(a few Small 9/16” Screw can be used to affix the
flex to the mount)
NOTE: For instructions on permanently
connected model (APTHC), please see Page 10
for Wiring Instructions. Please note that this
model requires a qualified person for installation.
Now fasten the unit to the wall using the 4 x 2”
screws provided.
Replace the front of the unit using the 4 Screw
Caps with the 4 original screws.
