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)
VH0024
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 AFORCED AIR SYSTEM)
VH0025
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) 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.
2.3 SIMPLIFIED INSTALLATION (CONNECTION TO AFORCED AIR SYSTEM)
VH0093
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.

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.
VD0305
Make sure the unit is level.
CAUTION
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 or supply furnace duct 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 or supply furnace duct connection installation only, to cut ductwork)
• Aluminum duct tape (for plenum connection installation only)
• Jig saw
• Caulking gun and caulking.
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.

HOW TO CONNECT THE FLEXIBLE DUCTS TO THE UNIT PORTS
Both flexible ducts attached to the diffusers must be connected to the bottom ports of
the unit. When facing the unit door, the fresh air to building port is located on left side
and the exhaust air from building port is on the right side. Refer to the identification
labels affixed beside each unit ports. Using tie wrap, attach the fresh air to building
duct to its corresponding port, then do the same for the exhaust air to building duct
and port. See illustration at right.
NOTE: Use an insulated duct if the duct will have to go through a space where it is
possible to experience extreme temperature conditions (eg: in northern area,
unheated attic in winter or uncooled attic in southern area). Also, if you plan to
stop the unit for more than 12 hours, we recommend to cover the duct with R12
insulation. VJ0107

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.
CAUTION
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 before performing any duct and port connection.
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

Apply duct tape gently to the joint in order to make an airtight
seal. See figures at right.
3.6.1 CONNECTION TO THE UNIT PORTS
VJ0102
Avoid compressing the insulation when you pull 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.
CAUTION
Choose an appropriate location for installing the exterior ports:
•There must be a minimum distance of 6’ (1.8 m) between the hoods to avoid cross-contamination
•There must be a minimum distance of 18” (457 mm) from the ground
3.6.2 LOCATING EXTERIOR PORTS
Make sure the fresh air intake port is
located at least 6 feet (1.8 m) away (or
more, as per applicable building codes or
standards) from sources of contamination
such as:
• Dryer exhaust, high efficiency furnace
vent, central vacuum vent
• Gas meter exhaust, gas barbecue grill

4. CONTROLS
4.2 BOOTING SEQUENCE
The unit booting sequence is similar to a personal 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 defrost control LED will light AMBER for 5 seconds, and then will shut off for 2 seconds.
After that, the LED will light RED for the rest of the booting sequence. 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.
4.3 SETTING EXTENDED DEFROST
The unit is factory set to normal defrost. In cold region (outside temperature -17°F [ -27°C] and lower), it may be
necessary to setup extended defrost. During the first 3 seconds of booting sequence, while the integrated
control LED is AMBER, press on push button for about 3 seconds.The LED will blink GREEN the number of times
corresponding to the actual defrost mode of the unit.
NOTE: During setting extended defrost, while the push button is pressed, the LED will light RED to indicate
the signal has been received.
Refer to table below to modify the defrost cycle of the unit. It is possible to change the selection as many times
needed.

4.4 ELECTRICAL CONNECTION TO WALL CONTROLS
For more convenience, this unit 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 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.
Use the terminal connector included in the installation kit to perform the electrical connection for
main and optional wall controls. Check if all wires are correctly inserted in their corresponding
holes in the terminal block. (A wire is correctly inserted when its orange receptacle is lower
than another one without wire. On picture at right, wire Ais correctly inserted, but not wire B.)

5. ELECTRICAL CONNECTION TO THE FURNACE
15
For a furnace connected to a cooling system:
On some older thermostat, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” terminal at the thermostat
and thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERNATE FURNACE INTERLOCK WIRING.
WARNING
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Use only the low
voltage class 2 circuit of the furnace blower control.

5. Furnace fan circuit must be class 2 circuit only.
• Risk of electric shocks.Before performing any maintenance or servicing,always disconnect the unit from its power source.
• This product is equipped with an overload protection (fuse). A blown fuse indicates an overload or a
short-circuit situation. If the fuse blows, unplug the product and check the polarity and voltage output from the
outlet. Replace the fuse as per the servicing instructions (refer to wiring diagram for proper fuse rating) and
verify the product. If the replaced fuse blows, it may be a short-circuit and the product must be discarded or
returned to an authorized service center for examination and/or repair.

7.1 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 located on the unit door.
7.2 PRELIMINARY STAGES TO BALANCE THE UNIT
• 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.
NOTE: The balancing dampers are NOT INCLUDED; to be supplied by others. Install the balancing dampers in Fresh air to
building duct and exhaust air from building duct (Aand Bon illustration below), at the more convenient place.
• Make sure all filters are clean (if it is not the first time you balance the unit).
7.3 BALANCING PROCEDURE
1. Set the unit to high speed.
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 32°F/0°C, 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.)
2. Place the magnehelic gauge on a level surface and adjust it to zero.
3. Connect tubing from gauge to exhaust air flow pressure taps
(see illustration at right).
Be sure to connect the tubes to their appropriate high/low
fittings. If the gauge drops below zero, reverse the tubing
connections.
NOTE: It is suggested to start with the exhaust air flow
reading because the exhaust has typically more
restriction than the fresh air, especially in cases of
fully ducted installations or source point ventilation.
Place the magnehelic gauge upright and level.
Record equivalent air flow of the reading according
to the balancing chart.
4. Move tubing to fresh air flow pressure taps (see diagram).
Adjust the fresh air balancing damper (A) until the fresh air
flow is approximately the same as the exhaust air flow. If
fresh air flow is less than exhaust air flow, then go back and adjust the exhaust balancing damper (B) to equal the fresh air flow.
5. Secure both dampers in place with a fastening screw.
6. Write the required air flow information on a label and affix it near the unit for future reference (date, maximum speed air flows,
your name, phone number and business address).
NOTE: 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.
