1. 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 or ceiling using brackets (included with the unit). If desired, an optional chains and spring kit
(part no. V61239, sold separately) can be used instead of brackets.
If required, bathroom fans and a range hood can 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: A standard 3-prong electrical outlet has to be available within 3 feet of the unit.
1.1 FOR HOUSE
1.1.1 F
ULLY 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.
1.1.2 C
ENTRAL 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 outdoors 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.
1.1.3 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.

1.2 FOR HIGH-RISE DWELLING
1.2.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING)
Stale air coming from the registers located in bathrooms and
kitchen is exhausted to the outdoors. Fresh air from outdoors is
filtered and supplied by the registers located in bedrooms and
living room.
See figure at right.
VH0095
1.2.2 CENTRAL DRAW POINT (CONNECTION TO A FAN -COIL SYSTEM)
Stale air coming from the registers located in bathrooms and
kitchen is exhausted to the outdoors. Fresh air from outdoors
is filtered and supplied to the supply duct of the fan-coil system
unit. See figure at right.
For this type of installation, it is not essential that the fan-coil
system blower runs when the unit is in operation, but we
recommend it.
2. INSTALLATION
2.1 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 hinges, power cord, etc.
• Open the unit door and inspect the interior of the unit for damage. Ensure that energy recovery core, core filters, insulation,
dampers, etc. are all intact.
2.2 UNIT PREPARATION
All units are equipped with 2 ports having integrated balancing damper (Fresh air to
building and Exhaust air to outdoors ports). Before installing the unit, check if these
2 ports are in wide open position. If not, proceed as follow:
Loosen the damper lever locking screw.
Use the damper lever to open the damper.
Lock the damper in position by tightening the locking screw.
VH0094
DAMPER LEVER
When loosing or tightening the damper lever locking screw, never use an electric screwdriver or drill,
use a standard screwdriver.

2. INSTALLATION (CONT’D)
2.3 LOCATING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is kept between 65°F and 104°F.
• 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 within 3 feet (standard 3-prong grounding outlet).
2.4 HOW TO HANG THE UNIT
Never handle the unit using its ports; hold the unit by its sides.
Hang the unit using 2 included brackets. See below.
To ensure occupants safety, ensure the brackets are mounted to solid surface (e.g.: concrete ceiling, joists).
The included screws are for wood joist only; do not use them to secure brackets to concrete ceiling or metal joists.
Mount brackets to ceiling or joists. To ease the brackets location, use the template printed on the cardboard filler located in
the unit box. See below.

WARNING
Ensure the unit is completely held by the brackets before continuing the installation.
NOTE: The unit can also be hung using 4 hooks (shaded part in illustration
at right), chains, springs and screws
(kit sold separately, part no. V61239).
CAUTION
Make sure the unit is level.

2. INSTALLATION (CONT’D)
2.5 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.
2.6 INSTALLING THE DUCTWORK AND REGISTERS
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.
2.6.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTIONS 1.1.1 AND 1.2.1)
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 from the range.
• Install the registers 6 to 12 inches 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 from the ceiling on an interior wall.
• If a register must be floor installed, direct the airflow up the wall.
