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)
VH0071
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.
2.2 CENTRAL DRAW POINT (CONNECTION TO AFORCED 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.
VH0072
2.3 SIMPLIFIED INSTALLATION (CONNECTION TO AFORCED 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.
VH0073

2. TYPICAL INSTALLATIONS ( CONT’D)
2.4 ATTIC INSTALLATION FOR ERV140TE ONLY
All three types of installation can be used in the attic (Fully ducted, Central Draw Point or Simplified). The example shown below is a
Simplified Installation (connection to a forced air system).
NOTE: To get the most of your ERV unit, the ambient temperature around the unit should be conditioned. If the unit has to be installed
in a unconditioned space, the heat gains or losses from the unit and the ducts could increase the operation costs of the unit.
CAUTION
•Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.
•The attic temperature must always be above 50°F (10°C) and under 122°F (50°C).
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.
VH0076
3. INSTALLATION
3.1 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.
3.2 UNIT DOORS
For more convenience, these units have one front door and one back door.
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 semi-annual
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. 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 at right.
VD0205
CAUTION
Make sure the unit is level.

3. INSTALLATION (CONT’D)
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 CALCULATING DUCT SIZE
Use the table below to ensure that the ducts you intend to install will be carrying air flows at or under the recommended values.
Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its air flow exceeds
the maximum value.
DUCT DIAMETER RECOMMENDED AIR FLOW MAXIMUM AIR FLOW
4” Ø (102 MM) 40 CFM (19 L/SOR 68 M³/H) 60 CFM (28 L/SOR 102 M³/H)
5” Ø (127 MM) 75 CFM (35 L/SOR 127 M³/H)110CFM (52 L/SOR 187 M³/H)
6” Ø (152 MM) 120 CFM (57 L/SOR 204 M³/H) 180 CFM (85 L/SOR 306 M³/H)
NOTE: Examples 3.5.1 and 3.5.2 use imperial units. The same calculation applies to metric units.
3.5.1 EXAMPLE OF CALCULATION
Problem: My installation requires two exhaust registers (one for the kitchen, and the other for
the bathroom). I will connect these registers to a main duct which will connect to the unit (high
speed performance value of 140 cfm). What size of duct should I use for the main exhaust duct
and for both end branches leading to the registers? (See illustration at right.)
Solution: Simplified method. (For a more detailed method of calculating duct size, refer to the
ASHRAE or HRAI HANDBOOK.)
Main duct: Table indicates for a 6” Ø duct: recommended air flow: 120 cfm, maximum air flow:
180 cfm. The 140 cfm high speed air flow is close enough to the recommended value (120)
and far away enough from the maximum value (180). Therefore, a 6” Ø duct or larger is an
appropriate choice for the main exhaust duct.
End branches: Each end branch will have to transport a 70 cfm air flow (140 divided by 2).Table
indicates for a 5” Ø duct: recommended air flow: 75 cfm; maximum air flow: 110 cfm. The high
speed air flow of 70 cfm is close enough to the recommended value (75) and far away enough
from the maximum value (110). Therefore, a 5” Ø duct or larger is an appropriate choice for both
end branches.
NOTE: A 4” Ø duct would have been too small because the maximum acceptable value for a 4” Ø duct is 60 cfm.
3.5.2 Example of a design for a fully ducted system with a unit having a high speed performance of 160 cfm.

3. INSTALLATION (CONT’D)
3.6 INSTALLING THE DUCTWORK AND REGISTERS
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.
• If possible, measure the velocity of the air flowing through the registers. If the velocity is higher than 400 ft/min (122 m/min), then
the register type is too small. Replace with a larger one.
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.
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.
3.6.2 CENTRAL DRAW POINT SYSTEM (AS ILLUSTRATED IN SECTION 2.2)
Stale air exhaust ductwork
Same as for Fully Ducted System, described on point 3.6.1
Fresh air distribution ductwork
• 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 distribution port of the unit (use metal
duct, see figure at right).
• Make sure the unit duct forms an elbow inside the furnace/air handler ductwork.
• If desired, interlock (synchronize) the furnace/air handler blower operation (see
Section 5 ELECTRICAL CONNECTION TO FURNACE).
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 distribution port of the unit (see figure at
right).
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 ELECTRICAL
CONNECTION TO FURNACE).
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

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
electrical 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.
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 wire Bis
not.)

5. ELECTRICAL CONNECTION TO THE FURNACE
WARNING
!
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low
voltage class 2 circuit of the furnace blower control.
For a furnace connected to a cooling system:
On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” 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.

7. BALANCING THE UNIT
7.1 WHAT YOU NEED TO BALANCE THE UNIT
• A magnehelic gauge capable of measuring 0 to 1 inch of water (0 to 249 Pa) and 2 plastic
tubes.
• The balancing chart of the unit.
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 by setting both damper balancing tools completely vertical.
• Make sure all filters are clean (if it is not the first time the unit is balanced).
7.3 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 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 (the ones
with arrows, see insets in 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.
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.
See example below:
In that case, there is 150 CFM in FRESH air and 125 CFM in EXHAUST air. Then, adjust (close) the FRESH air balancing damper
until the FRESH air flow matchs the EXHAUST air flow: 125 CFM (0.67 in. w.g.) with magnehelic gauge connected to FRESH air
flow pressure taps).
7. Secure both dampers in place with a fastening screw (included).
8.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).
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.
