4.1 I C
NSPECT THE ONTENT OF THE
Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, ports, power cord, etc.
4.2 L
OCATING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is kept between
50°F and 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 (HRV units only). 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.
Make sure the unit is level.
4.3 P
LANNING OF THE
• 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.

ULLY UCTED
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 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 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.
