2. INSTALLATION
2.1 INSTALLING AFR
1. Determine in which area you would like to install your
QuietCool AFR.
2. From inside the attic, find the center point between the two
roof rafters and mark it as the center of the fan hole. Partially
insert a screw into the center point mark.
NOTE:
If you have a tile roof, you will need to move the
tiles out of the way before tracing and cutting.
3. Go to the roof. Using the screw as a reference point and the
provided template, trace out the 22” diameter circle.
4. Use a reciprocating saw to cut out the traced hole pattern
from the roof decking. Remove the cut out decking material
from around the hole as needed.
If installing on a tile roof, continue to step 5. If installing on
a shingle roof, skip to step 11.
5. Apply weatherproof barrier to the roof.
6. Position the fan so that it is centered with the vent hole.
7. Lifting the fan unit up at an angle, apply weatherproof sealant
to the bottom side of the fan unit. This will help keep the fan in
place and will seal nice and tight.
8. Using a minimum of 8 roofing nails, nail the fan to the roof
through the primary flashing. To prevent leaking, be sure to
apply weatherproof sealant on the nail heads. Once complete,
apply more weatherproof barrier to the top of the flashing.
9. Using sheets of aluminum, construct a secondary flashing out
of two pieces of material by cutting out a semi-circle shape on
either side while flaring up the edges that will stick up above
the tile, creating a “bib” that will go around the fan. Once
constructed, install the flashing material on top of the primary
flashing and attach using weatherproof sealant.
