5. INSTALLATION
5.1 PREPARING THE UNIT
The Fresh air to building and stale air to outdoors ports of these units are equipped with integrated balancing dampers. Before installing
the unit, make sure that both ports are fully open.
1. Loosen the damper lever locking screw.
2. Pivot the damper lever to fully open the damper, ensure that the lever rotation won't exceed 90° maximum
to avoid the damper not closing properly.
3. Hand tighten the damper lever locking screw to lock the damper in place.
CAUTION
When loosening or tightening the damper lever locking screw, never use an electric screwdriver
or drill. Use a standard screwdriver.
5.2 LOCATING THE UNIT
NOTE: your unit may be slightly different from the illustrations.
Choose an appropriate location for the unit:
• Within an area of the house where the ambient temperature is kept between 18°C (65°F) and 40°C (104°F)
• So as to provide easy access to the interior cabinet 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, electrical panel and other fire hazards
• Allow for a power source (standard outlet) within 3 feet
Mount the unit using the 2 included brackets, as follows:
1. Using the template printed on the cardboard filler in the box,
mount the brackets to the joists.
2. Use at least 2 screws or nails to secure each bracket to the
joists; the center one is optional.
CAUTION
Before installing this unit, please take the time to carefully read page 2 of this guide to ensure it is installed safely
and properly.
⚠ WARNING
Never handle the unit using its ports. Hold the unit by its sides.
⚠ WARNING
To ensure occupant's safety, ensure the brackets are mounted to a solid surface such as concrete or joists. Note
that the included screws are for wood joists only; do not use them to secure the brackets to a concrete ceiling or
metal joists.
