5.0 Typical Installation
(Primarily for homes with radiant hot water or
electric baseboard heating. See figure 1.)
Moist, stale air is exhausted from the high
humidity areas in the home, such as bathrooms,
kitchen and laundry room. Fresh air is supplied
to bedrooms and principal living areas.
The use of bathroom fans and a range hood is
suggested to better exhaust stale air.
Homes with more than one level require at least
one exhaust register at the highest level.
5.1 FULLY DUCTED SYSTEM
There are three (3) common installation methods.
4
figure 1
See 6.5.1
for details
5.2 EXHAUST DUCTED SYSTEM
(SOURCE POINT VENTILATION)
(For homes with forced air heating. See figure 2.)
Moist, stale air is exhausted from the high
humidity areas in the home, such as bathrooms,
kitchen and laundry room. Fresh air is supplied
to the cold air return or the supply duct of the
furnace.
The use of bathroom fans and a range hood is
suggested to better exhaust stale air.
Homes with more than one level require at least
one exhaust register at the highest level.
NOTE: For this type of installation, it is not
essential that the furnace blower runs
when the unit is in operation, but we
recommend it.
5
See 6.5.2
for details
figure 2
5.3 SIMPLIFIED
(VOLUME VENTILATION)
(For homes with forced air heating. See figure 3 or 4.)
Fresh air and exhaust air flow through the furnace ducts wich simplifies the installation.
The use of bathroom fans and a range hood is suggested to better exhaust stale air.
NOTE: For the installation type shown in figure 4, furnace blower should be running when the unit is
in operation.

6.0 Installation
6.1 ADJUSTING THE DAMPER ROD (FOR ERVS INSTALLED IN WARM REGIONS)
Refer to Section 4.2 and observe the difference in the damper
position at the right in diagrams Defrost Mode 1 and Defrost Mode 2:
for Defrost Mode 1 the damper is completely closed, whereas
for Defrost Mode 2 the damper is half closed. At the factory, all ERVs
are assembled for defrost Mode 2. Therefore, if your installation
is for an ERV in a warm region (zone D as defined in Section 3),
the rod must be moved to position 1 (see figure 5).
NOTE: Before attempting to change the position of the damper
rod, place the unit on a table for easy access and remove
the recovery core.
6.2 LOCATING AND MOUNTING THE UNIT
Choose an appropriate location for the unit:
• Within an area of the house where the temperature is above 10°C /
50°F (basement, attic, furnace room, laundry room, etc.).
• Away from living areas (dining room, living room, bedroom), if possible.
• So as to provide easy access to the interior cabinet and to
the control panel on the right hand side of the unit.
• Close to an exterior wall, so as to limit the length of the insulated
flexible duct to and from the unit.
• Close to a drain. If no drain is close by, use a pail to collect
run-off.
• Away from hot chimneys, electrical panel and other fire hazards.
• Allow for a power source (110 V standard outlet).
Hang the unit to ceiling joists with the 4 chains and
springs provided (see figures 6 and 7).
figure 6
figure 7
CAUTION
Make sure the unit is level.
CAUTION
This is a delicate operation: to avoid injury proceed carefully and use the appropriate tools.

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, door hinges, dampers, duct collars, cabinet, etc.
• Inspect the interior of the unit for damage. Ensure that the fan motor assembly, recovery core, insulation,
dampers, damper actuator and drain pan are all intact.
• If the unit was damaged during shipping, contact your local distributor. (Claim must be made within
24 hours after delivery.)
• Use checklist included with the unit to ensure that no parts are missing.

6.0 Installation (cont’d)
a) Follow the instructions in Section 6.4 below to determine the appropriate duct diameters for your system.
b) Keep it simple. Plan for a minimum number of bends and joints. Keep the length of insulated duct to
a minimum.
c) Do not use wall cavities as ducts. Do not use branch lines smaller than 4” (102 mm) Ø.
d) 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 recovery module. Use sheet metal for the kitchen
exhaust duct.
e) Be sure to plan for at least one exhaust register on the highest lived-in level of the house if it has
2 floors or more.
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.
NOTE: Examples 6.4.1 and 6.4.2 use imperial measures.
The same calculation applies to metric measures.
6.4.1 Example of calculation:
Problem: My installation requires two exhaust registers (one for the kitchen, one 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 the two end
branches leading to the registers? (See figure 8.)
Solution: Simplified method.
(For a more detailed method of calculating duct size refer to the
ASHRAE or HRAI HANDBOOK).
Main duct:
Table above indicates a 6” Ø duct: recommended air flow: 120 cfm; maximum air flow:
180 cfm. The high speed air flow of 140 cfm is close enough to the recommended value (120) and
far enough away from the maximum value (180). Therefore a 6ӯ duct or larger is an appropriate
choice for the main exhaust duct.
End branches: Each end branch will have to transport an air flow of 70 cfm (140 divided by 2). Table
above indicates a 5ӯ 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 enough away
from the maximum value (110). Therefore a 5ӯ duct or larger is an appropriate choice for the
2 end branches
.
NOTE: A 4ӯ duct would have been too small because the maximum acceptable value for a 4ӯ
duct is 60 cfm.

6.5.1 Fully Ducted System (as illustrated in Section 5.1)
Stale air exhaust ductwork:
• Install registers in areas where contaminants are produced: kitchen, bathrooms,
laundry room, etc.
• Install registers 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR
install them in the ceiling.
• Install the kitchen register at least 4 feet (1.2 m) from the range top.
• 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 registers in bedrooms, dining room, living room and basement.
• Install 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 level.)
• If a register must be floor installed, direct the air flow up the wall.

Stale air exhaust ductwork: (same as for Fully Ducted System, described on page 15)
Fresh air distribution:
There are two methods for connecting the unit to the furnace:
Method 1: supply side connection
• Cut an opening into the furnace supply duct at least
18 inches (0.5 m) from the furnace.
• Connect this opening to the fresh air distribution port
of the HRV/ERV (use steel duct, see figure 10).
• Make sure that the HRV/ERV duct forms an elbow
inside the furnace ductwork.
• If desired, interlock (synchronize) the furnace blower
operation with the HRV/ERV operation.
(See Section 8.4).
Method 2: return side connection
• Cut an opening into the furnace return duct not less than
10 feet (3.1 m) from the furnace (A+B).
• Connect this opening to the fresh air distribution port of
the HRV/ERV (see figure 11).
NOTE: For Method 2, it is not essential that the furnace
blower runs when the HRV/ERV is in operation,
but we recommend it. If desired, synchronize the
furnace blower operation (see Section 8.4).

(cont’d)
Insulated flexible duct
Use the following procedure for connecting the insulated flexible duct to the ports on the unit (exhaust to
outside and fresh air from outside).
a) Pull back the insulation to expose the flexible duct.
b) Connect the interior flexible duct to the port using a duct tie.
c) Carefully seal the connection with duct tape.
d) Pull the insulation over the joint and tuck it between the inner and outer rings of the double collar.
e) Pull the vapor barrier over the insulation and over the outer ring of the double collar.
f) Apply duct tape to the joint making an airtight seal
. Avoid compressing the insulation when you pull the
tape tightly around the joint. Compressed insulation loses its R value and causes water dripping due
to condensation on the exterior surface of the duct.
a) b) c) d), e) f)
Rigid duct:
Use duct tape to connect the rigid ducts to the ports.
Make sure that the 2 balancing dampers are left in a fully open position before
connecting the ducts to
these ports (fresh air distribution port and stale air exhaust port as shown on figure 14).

7.5 SPECIAL COLD WEATHER TBI MODE FOR ERVS
The enthalpic core installed in ERVs requires extra protection when the outside temperature drops below
-15°C (5°F).
A special operating mode called TBI (Time-Based Intermittent) is activated under these conditions.
Characteristics of cold weather TBI mode
• activated when the outside temperature drops below -15°C (5°F).
• 20/40 cycle (20 minutes LOW speed followed by 40 minutes OFF).
• usual control of air supply via the main wall control is suspended (except for the OFF position).
• optional control (20/40/60-minute push button) retain its temporary high speed activation capability.
• deactivated when the outside temperature warms up higher than -15°C (5°F).
7.3 OTHER FEATURES
FURNACE INTERLOCK (for forced air heating system)
The furnace fan can be interlocked so that it will run simultaneously with the ERV or HRV to ensure proper
distribution of fresh air throughout the house (see table section 7.4, to see if it is available on your unit).
PERMANENT MEMORY
Our electronic controls have a default memory feature in the event of a power outage. Even the date of the
last service reminder is maintained as a convenience to the homeowner.
CONTROL UPGRADES
All controls can be used on any ERV, so a Basic control can be upgraded to the Electronic in the future
(see table in Section 7.4 below for control availability according to the units).

Alternate furnace interlock wiring
For a furnace connected to 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”. An additional control relay will then have to be installed.

WHAT YOU NEED TO BALANCE THE UNIT
• A magnehelic gauge capable of measuring 0 to
0.25 inch of water (0 to 62.5 Pa) and 2 plastic
tubes.
• Two ”Flow Measuring Stations” or two flow
collars (the size will vary depending on the duct
diameter).
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 all filters are clean (if it is not the first time you balance the unit).
• Make sure the balancing dampers are fully open (F and G in figure 20).
Choose appropriate locations for the 2 flow collars (or flow measuring stations), according to figure 20:
• On the exhaust air duct (first measuring location, A)
• On the fresh air distribution duct (second measuring location, B
• At least 36” away from the unit; at least 12” before or after a 90° elbow; at least 12” away from a
register.
INSTALLATION OF FLOW COLLARS OR “FLOW MEASURING STATIONS”
• If you are using Flow Collars:
Insert the flow collars in the duct at each location. Make sure their arrows are pointing in the direction
of the airflow. Tape collars in place temporarily.
• If you are using “Flow Measuring Stations”:
Cut a 1” (25.4mm) diameter hole in the duct at each location. Insert the “Flow Measuring Stations”.
Make sure their arrows are pointing in the direction of the airflow. Tape the “Flow Measuring Stations”
in place temporarily.

BALANCING PROCEDURE
1. Set the unit to high speed.
Make sure that the furnace blower is ON if the installation is in any way connected to the ductwork of
the cold air return. If not, leave furnace 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.)
2. Place the magnehelic gauge on a level surface and adjust it to zero.
3. Connect tubing from gauge to flow collar (or “Flow Measuring Station”) in
exhaust air stream at location A. 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 and exhaust ducted installation.
Place the magnehelic gauge upright and level. Record the readings.
4. Move tubing to FRESH air flow on the other side of the unit (location B) and
note readings.
Adjust the fresh air balancing damper F until the reading at B is approximately
the same as the reading at A. If the reading at B is less than the reading at A,
then go back and adjust the exhaust balancing damper
G to equal the fresh
air flow.
5. Secure both dampers in place with tape or with a fastening screw.
6. If you are using flow collars, remove them, reconnect the duct and seal with duct tape. If you are using
“Flow Measuring Stations”, remove them and seal the holes with duct tape. 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: Most flow collar kits provide a conversion chart located on the collar which enables you to convert
magnehelic gauge readings to equivalent cfm values.
The unit is considered balanced even if there is a difference of +/- 10 cfm (+/- 0.015 inch w.g.)
between the two air flow readings.
If you are only using one flow collar or one “Flow Measuring Station”, then, after completing the
first reading, transfer this measuring device to the other side of the unit and take the second reading.
