2. TYPICAL INSTALLATIONS
Installations may vary according to the type of unit and the ports configuration (top or sides). 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 should 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.
VH0055
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.
VH0056
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.
NOTE: It is possible to connect the outside fresh air duct to the supply
duct of the forced air unit. To do so, the Automatic fresh air bypass
must be used (part #: 15391). (See installation sheet included with
the Automatic fresh air bypass).
To avoid cross-contamination and achieve the highest efficiencies, the
Automatic fresh air bypass (part #15391) must be installed. If not, the
forced air system blower must always be ON.
NOTE: Home with multiple forced air systems should have one unit on
each system.

NOTE:The ERV unit is designed to assist in the management of humidity introduced into the home.
During cooling season, in extreme humidity conditions, the use of additional dehumidification unit may be required to quickly
remove all excess moisture. During heating season, in extreme dryness conditions, the use of a humidifier may be required if
the indoor air is still too dry.
2.4.2 ERV UNITS ATTIC INSTALLATION
All 3 types of installations can be used in the attic (Fully ducted system, Central Draw Point or Simplified). The example shown below is
a Simplified installation (connection to a forced air system).
CAUTION
Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.
CAUTION
The attic temperature must always be above 0°C (32°F).
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.
NOTE: It is possible to connect the outside fresh air duct to the supply
duct of the forced air unit. To do so, the Automatic fresh air
bypass must be used (part #: 15205). (See installation sheet
included with the Automatic fresh air bypass).
To avoid cross-contamination and achieve the highest efficiencies, the
Automatic fresh air bypass (part #15205) must be installed. If not, the VH0058
forced air system blower must always be ON.
NOTE: Home with multiple forced air systems should have 1 unit on each system.

3. INSTALLATION
3.1 INSPECT THE CONTENTS
OF THE
BOX
• Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, door latches, power cord, etc.
• Remove and discard the 2 transport brackets (A) and open the door. Discard the styrofoam
A
fillers (ERV units only) and remove the hardware kit from the unit. Inspect the interior of the unit
for damage. Ensure that heat or energy recovery core, core filters, insulation, dampers, etc. are
all intact.
VD0183
3.2 LOCATING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is between 10°C (50°F) and 65°C (149°F) (basement, furnace room,
•
•
•
•
•
closet, etc.).
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).

CAUTION
Make sure the unit is level.
3.5 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.
3.6 INSTALLING THE DUCTWORK
AND
REGISTERS
! 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.

3.6.1 FULLY DUCTED SYSTEM (AS
ILLUSTRATED IN
SECTION 2.1)
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 in the ceiling OR 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall. The duct lenght should be
at least 15’ (4.6 m). (The fresh air will then flow through the room and mix with room air, ensuring a continuous renewed airflow.)
• If a register must be floor installed, direct the airflow up the wall.

When performing duct connections, always use approved tools and materials. Respect all corresponding laws and safety
regulations. Please refer to your local building code.
0
CAUTION
When performing duct connections to the furnace supply duct, this duct must be sized to support the additional airflow
produced by the HRV/ERV. Also, use a steel duct. It is recommended that the HRV/ERV is running when the furnace is in
operation to prevent backdrafting inside HRV/ERV.
There are 2 methods for connecting the unit to the furnace/air handler:
Method 1: Supply side connection
• Cut an opening into the furnace supply duct at least 18 inches (0.5 m) from the
furnace/air handler.
• Connect this opening to the Fresh air to building port of the HRV/ERV (use steel
duct, see figure beside).
• Make sure the HRV/ERV duct form an elbow inside the furnace/air handler ductwork.
• If desired, interlock (synchronize) the furnace/air handler blower operation (see
Section 5).
Method 2: Return side connection
• Cut an opening into the furnace return duct not less than 10 feet (3.1 m) from the
furnace/air handler (A+B).
• Connect this opening to the Fresh air to building port of the HRV/ERV
(see figure beside).
NOTE: For Method 2, it is not essential that the furnace/air handler runs when the
unit is operation, but we recommend it. If desired, interlock (synchronize) the
furnace/air handler blower operation (see Section 5).

Exhaust air flow
3. Connect tubing from gauge to EXHAUST air flow pressure taps (see diagram beside).
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 VP0015
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 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 to equal the fresh air flow.
5. Secure both dampers thumb screw in place with tape.
6. 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).
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.

8. CONNECTING THE DRAIN (HRV UNITS ONLY)
A
VD0181
From the inner side of the unit door, using the
provided drain tube, punch out both drain
holes (A).
VO0091
In order to keep the drain pan intact, hand
tighten the 2 plastic drain fittings to the unit
door using the gaskets and nuts as shown.
Tie-wrap
VO0092
VO0093
Cut 2 sections of plastic tubing, about 12”
(305 mm) long and attach them to each
drain fitting. Join the 2 short sections to the
«T» junction and main tube as shown.
To drain
Make a water trap loop in the tube to prevent
the unit from drawing unpleasant odors from
the drain source. Make sure this loop is
situated BELOW the «T» as shown. This will
prevent water from being drawn back up into
the unit in case of negative pressure. Run
the tube to the floor drain or to an alternative
drain pipe or pail. Be sure there is a slight
slope for the run-off.

•Unplug the unit. Disconnect the main control and the optional control(s)
damper port mechanism may be defective. (if need be). Wait 10 seconds and plug the unit back. Check if the damper
opens. If not, use a multimeter and check for 24V AC on J12-1 and J12-2
(in electrical compartment). If there is 24V AC, replace the entire port assembly.
NOTE: It is normal to experience a small delay (7-8 seconds) before
detecting the 24V AC signal at starting-up. This signal will stay
during 17-18 seconds before disappearing.
• The circuit board may be defective.
•If there is no 24V AC, replace the circuit board.
3. The wall control does not
work OR the indicators flash.
• The wires may be in reverse position.
• The wires may be broken.
• The wire in the wall OR the wall
control may be defective.
•Ensure that the color coded wires have been connected to their
appropriate places.
•Inspect every wire and replace any that are damaged.
•Remove the wall control and test it right beside the unit using another
shorter wire. If the wall control works there, change the wire. If it does
not, change the wall control.
4. The Humidity Control does
not work OR the 20-minute
push-button timer does not
work OR its indicator light
does not stay on.
• The wires may be in reverse position.
• The Humidity Control or push button
may be defective.
•Ensure that the color coded wires have been connected to their appropriate places.
•Jump the OL and OC terminals. If the
unit switch to high speed, remove the NO C NC I OC OL Y R G B
Humidity Control or push button and
test it right beside the unit using
beside the unit using another VE0098
shorter wire. If it works here, change
the wire. If it doesn’t, change the Humidity Control or the push button.
5. The supply and/or exhaust
motor do not work.
• The circuit board may be defective.
•Press on the integrated control push button until the unit turn on low
speed (the LED will light AMBER). Using a multimeter, check the voltage
on J4-1 and J4-2 (for supply motor), and on J5-1 and J5-2 (for exhaust
motor). The reading must be ± 68 V AC. Then set the unit on high
speed by pressing on the integrated control 1 more time (the LED will
light GREEN). Using a multimeter, check the voltage on J4-1 and J4-2
(for supply motor), and on J5-1 and J5-2 (for exhaust motor). The
reading must be ± 120 V AC. If all the readings correspond to the right
voltage values, the circuit board is not defective. If one or both readings
are different, change the circuit board.
• Using a multimeter, check the ohms value on each motor connectors. Black
motors values: For BLUE and BLACK motor wires, the right value is
± 55 ohms. For BLUE and BROWN motor wires, the right value is ± 35 ohms.
For BROWN and BLACK motor wires, the right value is ± 89 ohms. Aluminum
motors values: For BLUE and BLACK motor wires, the right value is ± 51 ohms.
For BLUE and BROWN motor wires, the right value is ± 47 ohms.For BROWN
and BLACK motor wires, the right value is ± 98 ohms. If the ohm values
are the same, the motor is not defective. Replace the motor capacitor.
