6.7.4 OPTIONAL ALPINE/PINE FILTER
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.
