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.
If required, bathroom fans and a range hood may 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, 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 registers 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.
VH0081
2.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM)
Stale air coming from the registers 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) or the supply duct 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.
VH0082
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) or the supply duct 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.

REPLACEMENT PARTS AND REPAIR:
In order to ensure your ventilation unit remains in good working condition,
you must use the manufacturer genuine replacement parts only. The
manufacturer replacement parts are specially designed for each unit and
are manufactured to comply with all the applicable certification standards
and maintain a high standard of safety. Any third party replacement part
used may cause serious damage and drastically reduce the performance
level of your unit, which will result in premature failing. The manufacturer
recommends to contact a certified service depot for all replacement parts
and repair.

4. INSTALLATION
4.1 INSPECT THE CONTENT OF THE BOX
Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, ports, power cord, etc.
4.2 LOCATING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is kept between
10°C (50°F) and 40°C (104 °F).
• Away from living areas (dining room, living room, bedroom), if possible.
• So as to provide easy access to the interior of the unit, for quarterly and annual
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).
• Close to a drain (HRV units only). If no drain is close by, use a pail to collect run-off.
Hang the unit with the four chains and springs provided. See illustration beside.
VD0242
CAUTION
Make sure the unit is level.
4.3 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.
4.4 INSTALLING THE DUCTWORK AND REGISTERS
4.4.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1)
! WARNING
Never install a stale air exhaust register 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 registers where the contaminants are produced: kitchen, living room, etc. Position the registers 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 a register is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.
• Install the registers 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install them in the ceiling.
Fresh air distribution ductwork
• Install the fresh air distribution registers in bedrooms, dining rooms, living room and basement.
• Keep in mind that the fresh air registers must be located as far as possible from the stale air registers.
• Install the registers either in the ceiling or high on the walls with air flow directed towards the ceiling. (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.

Same as for Fully Ducted System, described on point 4.4.1
! WARNING
When performing duct connections, always use approved tools and materials. Respect all corresponding
laws and safety regulations. Please refer to your local building code.
CAUTION
When performing duct connections to the furnace supply duct, this duct must be sized to support the
additional airflow produced by the unit. Also, the use of metal duct is highly recommended.
Fresh air distribution ductwork
There are 2 methods for connecting the unit to the furnace/air handler:
Method 1: Supply side connection

4. INSTALLATION (CONT’D)
4.5 CONNECTING THE DUCTS TO THE UNIT
NOTE: All units ports were created to be connected to ducts having a minimum of 4” diameter, but if need be, they can be connected
to bigger sized ducts by using an appropriate transition (e.g.: 4” diameter to 5” diameter transition).
Insulated flexible ducts
Use the following procedure to connect the insulated flexible ducts to the ports of the unit (Exhaust air to outside and Fresh air from
outside ports).
A
All units have those 2 ports equipped with integrated balancing damper. Prior to install the
insulated flexible ducts, ensure these both ports have their damper entirely open (their
adjusment pin (A) must be set vertical, as shown beside).
VJ0033
CAUTION
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts.
 Pull back the insulation to expose the flexible duct.
 Attach the flexible duct to the port using tie wrap.
 Pull the insulation over the joint and tuck in between the inner and outer rings of the double collar.
 Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Fasten in place the vapor
barrier using the port strap included in unit parts bag). To do so, insert one collar pin through vapor barrier and first strap hole, then insert
the other collar pin through vapor barrier and center strap hole and close the loop by inserting the first collar pin in the last strap hole.
CAUTION
Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation
within the ducts.

4.7 INSTALLING DUAL EXTERIOR HOOD USING TANDEM®* TRANSITION KIT (OPTIONAL)
If desired, a dual exterior hood can be used instead of 2 exterior hoods to connect
insulated ducts. The joist opening needed to install the Tandem® transition
must be 9¾” minimum. The maximum height of the Tandem® transition is 8¾”.
To connect 4” insulated flexible ducts to the 5” oval ends of the Tandem® transition
(Exhaust air to outside and Fresh air from outside), connect an adapter to the
Tandem® transition (not included).
VJ0118A
For each duct connection:
1. Slightly squeeze a section of 4” round metal duct, at least 8” long, to insert it into
the oval opening of the Tandem® transition and push it all the way in.
2. Using silicon, seal the joint between the outside of metal duct and Tandem®
transition, and allow silicon to dry completely.
CAUTION
When connecting insulated flexible duct to the Tandem® transition,
pull the interior flexible duct over the adapter all the way to the
silicon joint and secure using a tie wrap. Then pull the insulation
over the joint, making sure that no part is left without insulation.

5. CONTROLS
All units are equipped with an integrated control located on upper left side of the unit. Plug the unit.
5.1 BOOTING SEQUENCE
The unit booting sequence is similar to a personnal computer boot sequence. Each time the unit is plugged after being unplugged, or
after a power failure, the unit will perform a 30-second booting sequence before starting to operate.
During the booting sequence, the integrated control LED will light GREEN for 5 seconds, and then will turn RED. During this RED light
phase, the unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the RED
light turns off and the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.
5.2 INTEGRATED CONTROL
Use the push button (1) to control the unit. The LED (2) will then show on which mode the unit is in.
Refer to table below to see how to operate the unit using its integrated control.

setup extended defrost. During the first 2 seconds of booting sequence, while the integrated control LED is GREEN, press on push
button for 3 seconds to set the unit in extended defrost; the LED will blink AMBER to show the unit is in extended defrost mode. After
that, the LED will shut off, then light RED (the unit returns in its booting sequence).
5.4 ELECTRICAL CONNECTION TO MAIN CONTROLS
For more convenience, these units can also be controlled using an optional main wall control.
NOTES: 1. The integrated control must be turned OFF to use an optional main control.
2. If an optional auxiliary control is used, if activated, this auxiliary control will override the optional main control.
! WARNING
Always disconnect the unit before making any connections. Failure in disconnecting power could result in
electric shock or damage of the wall control or electronic module inside the unit.
CAUTION
Never install more than one optional main wall control per unit. Make sure that the wires do not short-circuit
between themselves or by touching any other components on the wall control. Avoid poor wiring connections.To
reduce electrical interference (noise) potential, do not run wall control wiring next to control contactors or near
light dimming circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.

8.1 WHAT YOU NEED TO BALANCE THE UNIT
• A magnehelic gauge capable of measuring 0 to 0.5 inch of water (0 to 125 Pa) and
2 plastic tubes.
• The balancing chart of the unit, located on the unit door.
VP0009
8.2 PRELIMINARY STAGES TO BALANCE THE UNIT
A
• Seal all the unit ductwork with tape. Close all windows and doors.
• Turn off all exhaust devices such as range hood, dryer and bathroom fans.
• Make sure the balancing dampers are fully open (their adjusment pin (A) must be set
vertical, see illustration beside).
• Make sure all filters are clean (if it is not the first time the unit is balanced).
VJ0033
8.3 BALANCING PROCEDURE
1. Set the unit to high speed.
NOTE: Make sure that the furnace/air handler blower is ON if the installation is in any way connected to the ductwork of the
cold air return. If not, leave furnace/air handler blower OFF. If the outside temperature is below 0°C/32°F, make sure
the unit is not running in defrost while balancing. (By waiting 10 minutes after plugging the unit in, you are assured that
the unit is not in a defrost cycle.)
FRESH AIR
2. Place the magnehelic gauge on a level surface and adjust it to zero.
FLOW
3. Connect tubing from gauge to EXHAUST air flow pressure taps (see diagram on unit
door).
Be sure to connect the tubes to their appropriate high/low fittings. If the gauge drops
below zero, reverse the tubing connections.
4. Note the CFM value from balancing chart on unit.
5. Repeat steps 3 and 4, but to FRESH air flow pressure taps.
6. Match highest CFM value to lowest by adjusting the balancing damper corresponding
to the highest value. To do so, rotate the adjusment pin.

In that case, there is 78 CFM in FRESH air and 61 CFM in EXHAUST air. Then, using the adjusment pin, adjust (close) the
FRESH air balancing damper until the FRESH air flow matchs the EXHAUST air flow: 60 CFM (0.2 in. w.g.) with magnehelic
gauge connected to FRESH air flow pressure taps).
7. Secure both dampers in place with a fastening screw (included in the hardware kit).
8. Write the required air flow information on a label and stick it near the unit for future
reference (date, maximum speed air flows, your name, phone number and business
address).
NOTES: 1. Use conversion chart provided with the unit to convert magnehelic gauge
readings to equivalent cfm values.
2. The unit is considered balanced even if there is a difference of ±10 cfm
(or ± 5 l/s or 17 m³/h) between the two air flows.
