2. TYPICAL INSTALLATIONS
Use the following illustrations as guidelines to help you decide on how the unit will be installed.
All the units should be hung from the joists.
In every case, bathroom fans and a range hood could be used to exhaust stale air. Also, for homes with more than one level, we recommend
one exhaust register at the highest level.
There are 3 installation methods: Fully Ducted System, Central Draw Point and Simplified Installation.
NOTE: An electrical outlet has to be available within 3 feet of the unit.
2.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING)
Stale air coming from the register located at the highest level of the
house is exhausted to the outside. Fresh air from outside is filtered and
supplied by the register located in the lowest liveable level.
Homes with more than one level require at least one exhaust register at
the highest level.
See figure at right.
2.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM)
Stale air coming from the register located at the highest level of the
house is exhausted to the outside. Fresh air from outside is filtered and
supplied to the return (plenum) of the forced air unit. See figure at right.
For this type of installation, it is not essential that the forced air system
blower runs when the unit is in operation, but we recommend it.
NOTE: Home with multiple forced air systems should have one unit on
each system.
CAUTION
Do not connect the unit to any forced air system supply
duct.
2.3 SIMPLIFIED INSTALLATION (CONNECTION TO A FORCED AIR SYSTEM)
Stale air is exhausted to the outside. Fresh air from outside is filtered and
supplied to the return (plenum) of the forced air unit.
See figure at right.
To avoid cross-contamination and achieve the highest efficiencies, the
forced air system blower must always be ON.
NOTE: Home with multiple forced air systems should have one unit on
each system.

3. INSTALLATION (CONT’D)
3.2 TOOLS AND MATERIAL
Following are the tools and material needed:
• Phillips no. 2 or Robertson no. 2 screwdriver
• Small flat blade screwdriver (for wall control connection)
• Wire stripper (for wall control connection)
• Hammer and flat blade screwdriver (for plenum connection installation only, to make holes in existing metal duct)
• Scissors or utility knife (to cut duct tape)
• Measuring tape
• Duct tape
• Tin snips or metal shear (for plenum connection installation only, to cut ductwork)
• Aluminum duct tape (for plenum connection installation only)
• Jig saw
• Caulking gun and caulking.
3.3 LOCATING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is kept between 50°F (10°C) and 104°F (40°C).
• Away from living areas (dining room, living room, bedroom), if possible.
• So as to provide easy access to the interior of the unit, for maintenance.
• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit.
• Away from hot chimneys and other fire hazards.
• Allow for a power source (standard 3-prong grounding outlet).
• FOR HRV UNITS ONLY: Close to a drain. If no drain is close by, use a pail to collect
run-off.
Hang the unit with the four hooks, chains and springs provided. See illustration at right.
CAUTION
Make sure the unit is level.
3.4 PLANNING OF THE DUCTWORK
• Keep it simple. Plan for a minimum of bends and joints.
• Keep the length of insulated ducts to a minimum.
• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or a range hood. This
would cause clogging of the filters and recovery module.
• If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level.
3.5 INSTALLING NON-INSULATED DUCTS AND DIFFUSERS
3.5.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1)
Never install a stale air exhaust diffuser in a closed room where a combustion device operates, such as a
gas furnace, a gas water heater or a fireplace.
Stale air exhaust ductwork
• Install the stale air exhaust diffuser in the main area where the contaminants are produced: kitchen, living room, etc. Position
the diffuser as far from the stairway as possible and in such a way that the air circulates in all the lived-in spaces in the house.
If desired, you can install another diffuser (sold separately).
• If a diffuser is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.
• Install the diffuser 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install it in the ceiling.

Fresh air distribution ductwork
• Install the fresh air distribution diffuser in a large, open area in the lowest level to ensure the greatest possible air circulation.
• Keep in mind that the fresh air diffuser must be located as far as possible from the stale air diffuser. If desired, you can install
another diffuser.
• Install the diffuser either in the ceiling OR 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall. (The cooler air
will then cross the upper part of the room and mix with room air, before descending to occupant’s level.)
• If a register must be floor installed, direct the airflow up the wall.
HOW TO CONNECT THE FLEXIBLE DUCTS TO THE DIFFUSERS
Once the diffusers location is determined, cut out 5¼” diameter hole.
Run one end of the flexible duct through the hole and fix it to the diffuser base (1),
using a tie wrap and duct tape. Assemble the diffuser base to the wall (or ceiling)
using its 4 no. 8 x 3/4” screws. Then, slide in the diffuser (2).

3.6 INSTALLING INSULATED FLEXIBLE DUCTS
Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation
within the ducts.
3.6.1 C
ONNECTION TO THE UNIT PORTS
Use the following procedure for connecting the insulated flexible ducts to the unit ports (exhaust air to outside and fresh air from
outside). Refer to identification labels beside ports before performing any duct and port connection.
Avoid compressing the insulation pulling the tape tightly around the joint. Compressed insulation loses its
insulation properties and causes water dripping due to condensation on the exterior surface of the duct.
For both remaining ducts, pull back the insulation to expose
the interior flexible duct.
Connect the interior flexible duct to the smaller part of the
inner ring of the port using a tie wrap.
Pull the insulation over the joint and tuck it between the
inner and outer rings of the port. Pull the vapor barrier over
the insulation and over the outer ring of the port.
Apply duct tape gently to the joint in order to make an airtight
seal. See figures at right.
