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.

Humidex
7
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.

Humidex

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.

Humidex

Steps for the HCS-APTHC only
The APTHC comes with a removable cover plate that needs to be attached to the unit’s back
plate after the wiring has been completed.
Before the wiring can be completed,
the EKO punch must be removed
from the back plate
An electrical fitting needs to be
installed. With the fitting installed the
wire can be inserted inside the unit and
connected.
Note: Fitting not included
Once the wire has been run through
the plate, you must connect the wire to
the unit matching the colors of the
inside wires. After the wiring has been
completed, you can attach the small
cover plate to the back plate and return
to the original installation procedures.

Humidex
11
Attaching the Flex and Outside Vent
From the outside, pull the flex pipe through the 6 ¼”
hole. Attach the vent to the 6” flex with the ½ in
screws provided.
Insert four 2 inch screws to secure the vent to the
outside wall. Make sure the vent is not twisted by
inserting the screws too tight and that the flaps are
working properly.
NOTE: If high winds are often present in the location of the vent, they may cause a
wind noise inside the house. If this is the case, an anti-gust hood (AGH-990) is
available from your Humidex dealer.
Now that the system has been mounted the HCS can be plugged into any 115V outlet.
Note: A grounded extension cord with a maximum length of 10 feet may be used if
necessary

Unit Operations
The first time the unit runs…
When the unit is first turned on, it will run at medium speed for 6 hours. During this initial 6-hour
period, it is important to allow it to run uninterrupted, since the unit will take readings that will be
important to determine the best operating speed that will, over time, get the most energy efficient
ventilation for the entire home and maximum reduction of relative humidity.
The HCS-APT and HCS-APTHC do not require the user to input any settings, the default humidity
setting will be set at 55% which will result in the best operation all year round. It truly is a set it and
forget it system.
After power outages or whenever the unit is powered down (unplugged) and powered up again
(plugged into the wall again), the unit reads the last recorded settings and will return to its regular
operation mode.
Note: For the unit to function properly and to allow the unit to provide the best energy efficient
ventilation and humidity control, all windows, doors with access to the outdoor and vents to the
outdoor should be closed to prevent an excessive amount of outdoor air from entering directly into
the house.
Maintaining your HCS
The HCS Products do not require any internal maintenance. The only maintenance needed for your
HCS is a periodic vacuuming of the dust accumulation at the intake grilles or louvers located at the
bottom of the unit. For proper functionality do not store anything within a radius of 4 feet around
the base of the Humidex.

What is the dew point?
The dew point is one of the three environmental variables that are important when discussing the
conditions in your home. Understanding the dew point will help you understand how the HCS unit
operates and how it will help to reduce the relative humidity (RH%) level infiltrating your home and
eliminate excess humidity, while providing energy efficient ventilation for your home. The dew point
is defined as the temperature at which the water vapor contained in a given volume of air will
condense into water. This is best illustrated by an example:
Assume the following measurements are taken by the unit:
Temperature = 68⁰F
Relative Humidity = 60%
Using the temperature and RH% values measured, we would calculate that the dew point in your
home is 54⁰F. As the temperature of surfaces in your dwelling (these tend to reflect the floor
temperature, which is generally cooler than the ceiling air temperature) approaches the value of the
dew point, you risk having condensation on those colder surfaces (as well as un-insulated water
pipes). This condensation can lead to problem situations that might produce unhealthy living
conditions in your home (odors, molds, etc.)
New Installations in the Summer
The late spring and early/mid-summertime temperature in most basements remains at approximately 59° to
66° F (15° to 19° C) whereas the air entering the basement from the upstairs of the house will generally be in
the range of 75° to 85° F (24° to 29° C) with a relative humidity of 70 to 75%. This air will have a dew point
(the temperature of surfaces on which it will condense, including basement surfaces) in the range of 64° to
76° F (18° to 24°).
When a Humidex is installed in these conditions, condensation may result, as the air from the upstairs comes
in contact with cold surfaces (i.e. concrete walls, floors, etc). The Humidex ventilation effect will over time
increase the basement temperature and help prevent this condition, however, during the initial operating
season; a small amount of heat may have to be added temporarily to the basement to increase its temperature.
If this condition occurs also reduce speed exhaust to medium.
If an air conditioner is present in the house, close all AC vents/leads/ducts to the basement.
COLD SURFACE FACTS –IMPORTANT
It is recommended that any exposed cold water pipes and A/C ducts should be insulated to reduce
condensation on these cold surfaces before a humidex is installed.

Most Common Issues
Mold, Mildew and Musty Smell
If mold or mildew is present prior to installing a Humidex, please have the contaminated area
cleaned. Not doing so could cause the Humidex to spread that mold to other locations in the
basement or crawlspace.
To avoid Mold, Mildew or Musty Smells:
-Follow the Recommendations on Page 13 (Concerning New Installations in the summer).
To ensure the proper functionality of the Humidex:
-Verify that the replenishment air is flowing from the upstairs to the downstairs.
-Increase ventilation in remote areas with a portable fan.
-Any exposed pipes and ducts should be insulated.
-Cinder block basement walls should be sealed with plastic vapor barrier or sealant.
-Dirt floor in crawl space or basement should be covered with vapor barrier.
-Sump pump should be equipped with a cover.
-Rainwater from the roof should be directed away from the basement or foundation.
-Landscaping should slope away from foundations.
-Insulating basement will reduce the condensation and also reduce the energy cost during
heating season.
Do not attempt to service the Humidex yourself. If you are not sure about certain functions, please
refer to Page 2.
