CSA F326 and Canadian Building Code:
• High speed:10 cfm per room
20 cfm for the master bedroom and the basement
• Low speed: 40-60% of high speed
ASHRAE Standard 62-2001:
• 0.35 air change per hour
Refer to ventilation code of your area to determine which method to use.

5.0 Typical Installations
(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 F ULLY D UCTED S YSTEM
There are three (3) common installation methods.

5.2 E XHAUST D UCTED S YSTEM (S OURCE P OINT V ENTILATION )
(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.

I NSPECT THE C ONTENTS OF THE B OX
• 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.
6.1 A DJUSTING THE D AMPER R OD (F OR ERV S I NSTALLED IN W ARM R EGIONS )
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.

6.0 Installation (cont’d)
6.2 L OCATING AND M OUNTING THE U NIT
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).

CAUTION
Make sure the unit is level.
6.3 P LANNING OF THE D UCTWORK
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.
6.4 C ALCULATING THE D UCT S IZE
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.

6.0 Installation (cont’d)
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 fromthe 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
on page 14 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.

6.0 Installation (cont’d)
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.
6.5.2 Exhaust Ducted System (Source Point Ventilation) (as illustrated in Section 5.2)
Stale air exhaust ductwork:(same as for Fully Ducted System, described in point 6.5.1)
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).

6.6 C ONNECTING D UCT TO THE U NIT
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 waterdripping due to
condensation on the exterior surface of the duct.
a) b) c) d), e) f)
CAUTION
Make sure that the vapor barrier on the insulated ducts does not tear during installation
to avoid condensation within the duct.

Choose an appropriate location for installing
the exterior hoods:
• a minimum distance of 6 feet (1.8 m)
between the hoods to avoid
cross-contamination
• a minimum distance of 18 inches
(457 mm) from the ground
Make sure the intake hood is at least 6 feet
(1.8 m) away from any of the following:
• dryer exhaust, high efficiency furnace
vent, central vacuum vent
• gas meter exhaust, gas barbecue-grill
• any exhaust from a combustion source
• garbage bin and any other source of
contamination
Refer to figure 15 for connecting the
insulated duct to the hoods. Place the
“FRESH AIR INTAKE” sticker, provided in the
installation kit, on corresponding hood. An
“Anti-Gust Intake Hood” should be installed
in regions where a lot of snow is expected to
fall.
CAUTION
All models require an exhaust hood with a backdraft damper.This damper closes when the unit is off
and prevents unwanted cold air from entering the house.
