Choose an appropriate location for the unit:
• Within an area of the house where the ambient temperature is kept between 50°F and 149°F;
• Away from living areas (dining room, living room, bedroom), if possible;
• So as to provide easy access to the interior cabinet for maintenance, and to the control panel on the side of the unit;
• Close to an exterior wall, so as to limit the length of the insulated exible ducts to and from the unit;
• HRV units only: 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 re hazards;
• Within 6 feet of a power source (standard outlet).
Consumer Information
A. To ensure quiet operation of the H/ERV, each product model must be installed using sound attenuation techniques appropriate for
the installation.
B. The way your heat/energy-recovery ventilator is installed can make a signicant difference to the electrical energy you use. To
minimize the electricity use of the heat/energy-recovery ventilator, a stand-alone fully ducted installation is recommended. If you
choose a simplied installation that operates your furnace air handler for room-to-room ventilation, an electrically efcient furnace that
has an electronically commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating
cost.
C. Installation of a user-accessible control with your product model will improve comfort and may signicantly reduce the product
model’s energy use.
CAUTION
Make sure that no piece of mineral wool will enter in the unit during installation. Otherwise, this could reduce airow and generate
vibrations and noise in the unit.

2.2.1 FULLY DUCTED SYSTEM (T-1) (THIS CONFIGURATION ALLOWS RECIRCULATION MODE TO OPERATE.)
2.2 INSTALLING THE DUCTWORK AND THE REGISTERS
Never install a stale air exhaust register in a room where there is a combustion device, such as a furnace, gas water heater, replace or
any appliance or equipment that can generate gaseous contaminants, or pollutants. The negative pressure this could create in the room
may impair proper evacuation of the gas or pollutants, which may have severe health consequences.
WARNING
!
STALE AIR FROM BUILDING:
Same as for Fully Ducted System, described on point 2.2.1.
FRESH AIR TO BUILDING:
• Connect the fresh air distribution duct of the unit to the central forced-
air system return duct at least 10 feet away from the central forced-air
system (A+B)*.
*This 10-ft. distance applies only in areas where the outside temperature
falls below the freezing point (32°F).
NOTE: The central forced-air system blower operation can be synchronized
with the unit (see section 3.3). It is recommended, but not essential that the
central forced-air system blower runs when the unit is in operation.
2.2.2 EXHAUST DUCTED SYSTEM (T-2) (THIS CONFIGURATION ALLOWS RECIRCULATION MODE TO OPERATE.)
Duct connection to the central forced-air system can be regulated by some codes and standards. It is your responsibility to consider and
comply with your local requirements to avoid any non-compliance.

If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation formation inside
and outside ducts, which could cause material damage and/or mold growth. Moreover, if fresh air to building duct and/or stale air
from building duct goes/go through an unconditioned space, the unit must be set to operate continuously in cold conditions (below
10°C/50°F). Continuous air movement inside ducts will prevent condensation formation. The unit can be stopped temporarily for
maintenance and/or repair purposes in such conditions.
CAUTION

2.2.3 SIMPLIFIED INSTALLATION (T-4) (THIS CONFIGURATION DOES NOT ALLOW RECIRCULATION MODE TO OPERATE.)
The central forced-air system must be synchronized with the unit since fresh air evacuation and distribution come from the same section.
The central forced-air system must operate to avoid fresh air to be directly drawn by the evacuation, which would reduce signicantly
fresh air supply to the building. See section 3.3 for ducting.
CAUTION
Duct connection to the central forced-air system can be regulated by some codes and standards. It is your responsibility to consider and
comply with your local requirements to avoid any non-compliance.
WARNING
!

TRANSITIONING TO 6-IN. DUCTS (FOR 110, 130 AND 150 CFM UNITS ONLY)
If using 6-in. ducts, install 5-in. to 6-in. transitions on the ports, and secure using duct tape only. If rigid ducting is used, install a 12-in.
section of exible duct between the transition and the rigid ducting (see above).
RIGID DUCTS
To prevent potential water leakage in cold side rigid ducting insulation, seal all rigid ducting joints with duct tape.
To avoid transmission of vibrations, always use a 12-inch section of exible duct to connect rigid ducts to the unit. To connect insulated
rigid ducts to the unit (cold side) using insulated exible ducts, follow instructions in section 2.5. To connect regular rigid ducts (warm
side) to the unit using non-insulated exible ducts, use a tie wrap.
2.6 CONNECTING THE DUCTS TO THE UNIT
INSULATED FLEXIBLE DUCTS
Use the following procedure to connect the insulated exible ducts to the ports of the unit (exhaust to outside and fresh air from outside).
1. Expose the exible duct by pulling back the insulation, and place it over the inner port ring.
2. Attach the exible duct to the port using a tie wrap.
3. Seal the joint using duct tape.
4. Pull the insulation and vapor barrier over the joint, tuck them between the inner and outer rings of the double collar and fasten them
in place using duct tape.

J0157
• If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation formation inside
and outside ducts, which could cause material damage and/or mold growth.
• Do not use screws to connect the ducts or transitions to the ports so as not to interfere with ports inner dampers operation. A
non-functioning damper could freeze the unit, which could cause damages.
CAUTION
The vapor barrier should remain intact and free of cracks or openings. An opening could produce condensation inside or outside duct,
which could cause material damage and/or mold growth in the long run.
CAUTION
2.5 INSTALLING THE EXTERIOR HOODS
To avoid cross-contamination:
• Keep at least 10 feet between both hoods OR use approved combined hoods
model VTYIK1.
• Install hood(s) at least at 18 inches away from the ground OR depth of expected
snow accumulation, whichever is greater.
Refer to illustration at right for proper connection method of the insulated ducts
to the hoods. An “Anti-Gust Intake Hood” should be installed in regions where a
lot of snow is expected to fall.
