INSTALLATION
Note: This ventilator is capable of replacing an existing
120 volt powered attic ventilator. Only a qualified per-
son should remove any electrical wiring in accordance
with local codes and standards.
1. Determine the sun’s best exposure location on your roof
barring shade (trees, other buildings etc.) at 4:00pm in
the hottest month of the year. Generally, we recommend
a point located 24” – 36” on center below the roof peak
and centrally along the ridgeline on the south, southwest,
or west side of the home.
2. Prior to installation, we recommend setting up the
ventilator to verify operation. Take the ventilator to a
location exposed to sun. Removing the cardboard
cover from the solar panel should cause the ventilator
to operate. Secure cardboard in place over solar panel
(for safety).
3. Separate the dome from the base by removing four (4)
5/16” stainless steel sheet metal screws. Set dome aside.
