1. Locate the roof panel of your greenhouse that gets the most constant sun and is also perpendicular to the sunlight.
There cannot be any shadows or shade on the solar photo voltaic cell panel surface. The Solar Fan cannot be installed
at a low point to avoid water entering through the air bleed holes. Hold your Solar Fan with the panel up to the sun to
test that your unit works, turn the thermostat dial until the fan begins to spin.
2. Install the (2) Support Braces to the 602B’s with the M6x14mm nut and bolt combo leaving about a 9” gap between
the two Support Braces.Locate the center of the panel, and mark an 8” x 8“ square in the center of the panel where
the Solar Fan will fit into place. Double check that the area you have selected to place the fan is going to fit the fan and
the threaded holes on the interior fan side of the unit are going to align with the Support Braces. Also check that it is
in the direct sunlight before you cut the polycarbonate panel, and make sure there are no vent holes on the upper side
to prevent water from entering. It is helpful to have a second person to hold the Solar Fan into place on the outside,
while the person inside confirms placement. See .
3. Cut the panel with a utility knife then test by placing the Solar Fan into the square to confirm the fit. If fit is correct
apply silicone caulk liberally around the side with the fan that will face the polycarbonate panel, see .
