NIT
Choose an appropriate location for the unit.
•
Within an area of the house where the ambient temperature is between 10°C (50°F) and 50°C (122°F) (basement, furnace room,
closet, etc.).
• Away from living areas (dining room, living room, bedroom), if possible
•
So as to provide easy access to the interior of the unit, for 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. If no drain is close by, use a pail to collect run-off.
Hang the unit with the four chains and springs provided.

LANNING OF THE
D
UCTWORK
• 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.
