QC-1000 rough opening is 12-3/4” x 21-1/2”
2. Determine from down below in which areas you would like to install your
QuietCool fans.
3. Go up into the attic to mark the exact location for each fan. Take the cardboard
cut-out template and a small screwdriver with you. When you nd a location,
move the insulation away to get a clear view. Make sure the template ts
between the framing, and there are no obstructions in your chosen location.
When you have chosen your exact spot, place the template on the spot and
mark it at each corner by pushing the screwdriver through at each corner to
make a hole so that you can nd it from below.
Repeat these steps at each location
4. From below, place the cut-out template on the ceiling at each location, making
sure that you have at least 2 inches of clearance all around it, because the grill
that will be installed later is 2 inches larger than the cut-out template. While
holding the template in place, mark its outline with a pencil. Using a drywall saw
or similar device, cut out the hole in the ceiling.
Repeat these steps at each location
