1.
For each exterior hood, using a jigsaw, cut a 6’’ diameter hole (if using 5’’ dia. insulated duct) or a 7’’ diameter hole (if using 6’’ dia.
insulated duct) in the exterior wall. Identify each insulated duct. For fresh air from outside duct, use the blue sticker dots (one at
each end). For exhaust to outside duct, use the red sticker dots (one dot at each end). Run each flexible duct through its respective hole
in the wall.
2.
Pull back the insulation to expose the flexible duct and, using a tie wrap, attach it to the inner
ring of the exterior backplate (5’’ ring for the 5’’ insulated ducts or 6’’ ring for the 6’’ insulated
ducts). Carefully seal with duct tape (

over the insulation and over the outer ring of the exterior backplate. Apply gently duct tape to
the joint making an airtight seal (

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 optional exterior single 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 assembled 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.
NOTE: Roof top venting is not recommended.
