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 outdoors. Fresh air from outdoors 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.
VH0071
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 outdoors. 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 A FORCED AIR SYSTEM)
Stale air is exhausted to the outdoors. Fresh air from outdoors 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 AVS E15 ECM ERV 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 10°C (50°F) and under 50°C (122°F).
Stale air is exhausted to the outdoors. Fresh air from outdoors 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 DOOR(S)
The AVS E15 ECM ERV, AVS E15 ECM HRV, 90H-V ECM ERV and the
90H-V ECM HRV units have one front door and one back door while the
AVS E15 HRV, AVS E10 HRV, 90H-V+ and the 60H-V+ units only have one
door. For these last models, the unit door can be relocated on the back of the
unit. This can be helpful to optimize duct configuration while keeping access
for unit maintenance. To change door location, follow these steps:
A
B
3
A. Remove both door lower mechanical screws no. 8-32 x 1” (1) and set
aside.
B. Open (2) and lift out the door (3).
To remove unit back panel, repeat steps A and B, but instead of removing
2 mechanical screws, there are 4 mechanical screws to be removed. Hang
the door to the back of the unit and secure it by tightening its both lower
mechanical screws. Hang back panel to the front of the unit and secure it by
tightening its four metal screws.

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 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. 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.
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/S OR 68 M³/H)
60 CFM (28 L/S OR 102 M³/H)
5” Ø (127 MM)
75 CFM (35 L/S OR 127 M³/H)
110 CFM (52 L/S OR 187 M³/H)
6” Ø (152 MM)
120 CFM (57 L/S OR 204 M³/H)
180 CFM (85 L/S OR 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.)
END
BRANCHES
5" Ø,
Solution: Simplified method. (For a more detailed method of calculating duct size, refer to the 70 CFM
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
VI0016
end branches.
MAIN BRANCH
6" Ø, 140 CFM
NOTE: A 4” Ø duct would have been too small because the maximum acceptable value for a 4” Ø duct is 60 cfm.

3.6 INSTALLING THE DUCTWORK AND REGISTERS
3.6.1 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.
• 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.
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
! 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
• 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).

3.7 CONNECTING THE DUCTS TO THE UNIT
NOTE: All unit ports are were created to be connected to ducts having a minimum of 6” diameter, but if need be, they can
be connected to bigger sized ducts by using an appropriate transition (e.g.: 6” diameter to 7” 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).
CAUTION
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts.
1.

4. CONTROLS
All units are equipped with an integrated control located under the unit, on the recessed side of electrical compartment. Plug the unit.
4.1 UNITS 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.
4.1.1 AVS E15 ECM ERV, AVS E15 ECM HRV, 90H-V ECM ERV and 90H-V ECM HRV
During the booting sequence, the integrated control LED will light AMBER for 10 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. CONTROLS (CONT’D)
4.5 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, it’s activation 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.
B
A
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 A is correctly inserted, but wire B is 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.

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.

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).
FASTENING SCREW
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.
