The special design of this filter makes it much more efficient to catch spores and their particles during
intensive pollen season. Using this optional fine mesh filter will extend the life expectancy of your prefilter.
To install it, remove the bottom metal screen of the AirDuo™ exterior hood and replace it by the optional
Alpine/pine filter. See illustration beside.
(Alpine/pine filter part number: ACCGSUP5)
During pollen season, or as needed, remove the asembled hood from its backplate by removing its 2 retaining screws. Then, slide out
the Alpine/pine filter and clean it under water. Let dry before reinstalling it on the assembled hood. Reinstall the hood on its backplate.

OCATING THE
Due to its particular design, the AirDuo™ exterior hood must be used only for exhaust hood when performing an installation
using 2 exterior hoods. Use the optional single fresh air intake exterior hood for supply air.
Make sure the optional exterior single hood is at least 6 feet (1.8 m) away (or more, as per applicable building codes or standards)
from sources of contamination such as:
• High efficiency furnace vent.
• Gas meter exhaust, gas barbecue-grill.
The AirDuo™ exterior hood must be installed at a minimum distance of 4 inches (102 mm) from the ground, and the optional single fresh
air intake exterior hood must be installed at a minimum distance of 18 inches (457 mm) from the ground. Also, a minimum distance of
6 feet (1.8 m) is required between the hoods to avoid cross-contamination. See illustration below.
