Choosing the Right Location for Airow
Choose a location to install your QuietCool AFR SLR roof mounted fan that allows for balanced airow throughout the
attic space. We always recommend the fan to be installed centrally located on the roof three feet below the ridge line.
This will allow you to access the fan very easily. Your roof mount fan should not be installed any closer than within 5 feet
to an existing passive vent, ridge vent, or additional fan unit.
Roof Pitch Requirements (Max Roof Pitch - 8/12)
For roofs with less than a 3/12 roof pitch, the fan should be curb mounted using accessory SLR-CRB-2424
IMPORTANT: DO NOT CUT THROUGH ANY RAFTERS OR STRUCTURAL MEMBERS WHILE CUTTING THE VENT
HOLE. ONLY CUT OUT THE ROOF DECKING.
Choosing the Right Location for the Best Sunlight
Choose a location to install your QuietCool AFR SLR fan or AFG SLR solar panel is very important based on the sun’s
path during the day. The optimal adjustment is to have the panel 90 degrees to the midday path of the sun. Be sure to
consider potential obstructions such as trees and other homes which may shade the solar panel during certain times of
the day. Most of the time, in the United States, you will want to have the panel facing south.
If a southern or western exposure is not possible, the fan can be installed on any other exposure and the solar panel can
be adjusted to capture maximum sunlight
There are many smartphone apps that can help in nding the best location for your solar panel based on the sun’s
location throughout the day.
