3.  From below, place the cut-out template on the ceiling, 
making sure that you have at least 2 inches of 
clearance all around it. While holding the template in 
place, mark its outline with a pencil. 
4.  Using a drywall saw or similar device, cut out the hole 
in the ceiling.
5.  Open and unpack your QuietCool fan. 
TIP: If your attic is very tight, you may want 
to wire your QuietCool motor housing before 
bringing it into the attic. Please follow the wiring diagrams that start on page 13. 
6.  Take the main assembly, which includes the motor 
housing, damper box, and duct into the attic through 
the crawl hole and move into position near the ceiling 
cut-out hole.
  TIP: If your attic access is far from your fan 
location, you can remove the duct from the motor 
housing and pass the motor housing, duct, and 
damper box through the ceiling cut out hole and 
reattach the duct to the motor housing in the 
attic. 
7.  Pre-screw two wood screws into the rafter almost all the way. Using the new hanger strap with eyelet 
holes, hang the motor head from the two wood screws and tighten the screws. Make sure that the 
handy box on the motor head is at the very top. Secure duct to damper box using three black sharp 
screws. Make sure the housing is angeled slightly up and the duct has a gentle 90 degree bend to 
help reduce noise level. The angle is important so the fan does not disturb any blown-in insulation in 
your attic. 
NOTE: Once your QuietCool fan is hung, it’s time to go below and install the damper box and 
ceiling grille.
