Safety Information
Safety precautions should be taken when performing the roofing work described in this installation guide.
You can significantly reduce your risk of danger by following the below recommendations:
• Do not perform roofing work in wet or windy conditions
• Tie-o both yourself and your equipment when working on steep pitched roofs to avoid falls
• Wear safety glasses and protective gloves when using power tools
• Always wear slip-resistant shoes when working on the roof
• Do not cut through any rafters or structural members of the roof during installation
• Leave the solar panel covered until your installation is complete
Choosing the Right Location
Choose a location to install your solar attic fan that allows for balanced air flow throughout the attic space.
The solar fan should be installed roughly centered on the roof and three feet below the ridge line. For
optimum performance, choose an area on the south side of your roof that is not shaded or blocked from
the sun for extended periods throughout the day. If a location on the southern side of your roof is not
available, you may raise the solar panel mounting bracket and face the fan unit toward the south for better
sun exposure. Your solar attic fan should not be installed any closer than within 10 feet to an existing passive
vent, ridge vent, or additional fan unit.
Ventilation Requirements
In order for your Cardinal Ventilation solar attic fan to operate at maximum performance, your attic must
have enough intake ventilation (net free area) to support the amount of air that your fan is moving. We
recommend a minimum of 5.5 square feet of net free area intake ventilation for best performance.
Your local building code may require specific fasteners or anchoring systems not discussed in
this installation guide. If installing this product in an area of either Florida or Texas that has been
designated as a high velocity wind zone area, review applicable building code requirements for
additional installation instructions.
