Key Installation Facts
1) Unit must be installed at floor level –approximately 3” off the floor.
2) Replenishment air has to flow from upstairs into the basement or crawlspace. Open doors
that can be closed are not a substitute for a properly installed vent.
3) Unit should be installed as far away as possible from the source of replenishment air.
4) Outside duct must be no less than 6” and dedicated for the Humidex unit only.
5) Maximum circulation is required to draw in air from all parts of the crawlspace.
6) Unit should not be installed within 8 feet of combustion appliance.
IMPORTANT –What Not to Do
1) DO NOT install the unit more than approx. 3 inches off the floor.
2) DO NOT make more than one turn with the duct and the ductwork should not be longer than 3
feet in total, unless rigid ducting is used - see ‘ducting” following.
3) DO NOT crush the vinyl Pipe.
4) DO NOT install the unit next to a replenishment air supply.

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 setting the controls of exhaust appliances, including the Humidex
at less than maximum speed during the heating season (Note: when humidity conditions in the
home are below the humidity setting on the Humidex, as they usually are during the heating season,
the Humidex operates at approx. 25% of the capacity of a standard bathroom fan), or 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.
Ideal location of the Unit
-Air drawn in by Humidex pulls moisture off the surface floors and walls. To maximize the
effectiveness;
A) Install unit in dampest, coolest and lowest part of crawlspace.
B) If possible, without hindering point “A”, install the Humidex as far away as possible from
the source of replenishment air (i.e. stairwell) from upstairs or from replenishment air grill in
crawl space area. This will allow for the unit to draw in the maximum moisture across the
greatest surface distance before the upstairs replenishment air is pulled into the unit.
-Keep away from sources of excess heat (i.e. furnace room).
-Unit must be installed all the way down to floor level, in order to draw in the moisture. It
should be approx. 3” and must not be higher than a max of 6 inches off floor level.
-Keep at least 8 feet away from furnace or combustion appliance, to avoid interfering with
airflow.
-The area (not less than 4 ft.) around the unit should be clear to allow the air to be pulled into the
vents.

Installation
Factors to consider
The installation must be done in the crawlspace 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 Minimum distance to any source of heat should be 8 feet.
Make sure that you do not install the unit in a boiler room.
Also maximize the distance between the unit and the source of replenishment air (example: stairwell or
openings to upper level).
For 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
location is above ground level. Also make sure that the hole doesn’t line up with a stud, electrical
wires, or pipe.
Ducting
You can duct from the back of the unit, or from the top of the unit by removing the top cover.
Duct can go through an outside wall, the floor joist or window. Duct should be vented above
ground level to the outside or below ground into a window well that is open and not sealed off to
the outdoors. The outside louver should be high enough to avoid infiltration of snow, flooding and
rodents, etc. All necessary parts and outside louvers are included.
When ducting the unit outside, no more than 3 feet of Vinyl Flex should be used. When
circumstances are that a longer span is required, 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. Duct has to be dedicated and not
combined with any other existing ductwork in operation. Seal well around the outside opening.

Preparing the CCC-103E for Installation
Measure the required Unit height. Remember that the units cannot be higher than 3”
to 6”off the ground.
From the inside, drill a pilot hole
of approximately ¼” at the
center of the proposed 6¼”
hole.
Outside the building, find the
pilot hole. 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.

Humidex

Attaching the Flex, Pipe and Vent
Attach the flex to the vent with the provided screws.
From the outside, push the flex through the 6 ¼”
hole.
Make sure the vent is not twisted by inserting the
screws too tight and that the flaps are working
properly. Attach the vent to the outside wall with the
provided screws
From the inside measure the distance between the
elbow and the flex. Cut off the excess flex. If this is
not done, the efficiency of the unit will diminish
drastically.

Humidex
9
Fasten Unit to the Wall
Now that the flex is tight, it can be attached to the elbow
with the tie wrap. Flex should not be kinked in any way.
Leaving a 1-inch gap between the top of the unit and the
ceiling (In case of a finished ceiling, leave a 1/8-inch gap
between the top of the unit and the ceiling avoiding any
contact between the two) drill ¼” pilot holes through the
lips of the unit and the wall.
Apply the four plastics anchors on the wall with the help of a
hammer. Secure the Humidex to the wall using the four 1 ¼
inch screws provided.
Once the unit is properly installed, return outside, apply
exterior caulking, to the vent, to act as a weather seal.
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.
Installing the CCC-103R
To allow the booster fan to draw air from the upper levels, a universal boot must be
installed. First cut out a whole to fit the universal boot.
Mount CCC-103R booster fan on floor joist a minimum of 6’ away from the universal
boot to reduce noise. Connect universal boot to booster fan with a 6” insulated flex.
The CCC-103R booster fan must be plugged into the outlet located on the CCC-103E
unit. Note: An extension may be needed
A T-junction duct and flex can be added to the exhaust side of the CCC-103R to direct
air into all areas of the crawl space.

Unit Operations
How a Humidex Works
Humidex is a mechanical ventilation appliance installed in the lowest level of a home, (basement or
crawlspace), engineered to expel moisture-laden air that stagnates due to poor air circulation. Cool,
moist air will gravitate to the lowest point of the home, which is the basement or crawlspace in a
multi-level home and where it can condense on the cooler floor/wall surfaces. The lack of proper
ventilation in the crawlspace creates an environment where the damp air will stagnate and emit
odors, nurture the development of molds, mildew and saturate into the structure, i.e. walls, floors,
frame works, drywall, as well as contents.
A quiet powerful fan in the unit draws the moist surface air in through the bottom vents and then
expels it out of the house through a 6-inch duct. The expelled air is replaced with a flow of fresh,
dry, warmer replenishment air drawn downward from the upper level, which raises the temperature
and lowers the relative humidity. The humidistat control in the unit measures the relative humidity
of the air flowing out. When the humidity drops to below the set level, the unit will decrease the
flow of air to a minimum.
The air flow will draw in the surface moisture and effectively “dry out” the structure. This decreases
mildew and mold activity by not allowing the moist air to stagnate and nurture their growth.
In the summer, with air conditioning running the replenishment air is dehumidified which will assist
in lowering the relative humidity and in the drying out process.
When there is no air conditioning, the air upstairs is warmer and will raise the dew point downstairs
as it eventually warms the crawlspace to reduce condensation.
In the winter, the air upstairs flows downstairs, this is then replaced by dryer outside air, thus
reducing window condensation and lowering the humidity upstairs. The warmer replenishment air
will raise the downstairs temperature. The heat in the house accompanied with the dry air (Dryer air
requires less energy to heat) will result in the Humidex working at a low speed; enough to maintain a
minimal airflow with minimal energy costs.
The air that flows downstairs is replaced with air that seeps into the house through openings or
building air leakage. The direct effect of the air being expelled and the flow of the air downstairs
create an air exchange in the house several times a day, expelling gases, toxins and contaminants
trapped in the air and providing fresh clean air necessary for good indoor air quality.
In this manner, Humidex helps control the relative humidity level in the home, reduces moisture
related problems and provides recommended air exchanges for a healthy, drier home environment.
Vacant Homes
Performance results are maximized when the building is occupied. If home is vacant for a prolonged
period of time, then the unit should be set to operate at low speed. A fresh air intake supply is
recommended via a small opening in a window upstairs or a supply vent such as the ASV-90.

Humidex
13
The Control Panel
-The switch will allow you to vary the rate of airflow.
-The Knob allows you to select the desired humidity.
By default, you should set the fan speed on High and set the humidity control at the desired level,
usually around 50%.
Note: For winter operation if there is still condensation on the windows when the humidity
drops below 50%, lower the humidity control by a few percent (45-47%).
Make sure not to set it too low to ensure a healthy home since some people will be affected by dry
conditions.
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 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
Maintaining your Humidex
Do not store anything within a radius of 4 feet around the base of the Humidex.
Make sure the basement or crawlspace has adequate replenishment air from upstairs, from a location
as far from the Humidex as possible.
The only maintenance needed for your Humidex is a periodic vacuuming of the dust accumulation
at the intake grilles or louvers located at the bottom of the unit.

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 12 (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 the basement or crawlspace 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.
