Step 4Attaching the Backing to the Frame
Next it is time to attach the back of the collector to the window frame. Insert one of the ends of the refrigerator backing into the appropriate hole that was drilled into the window frame. Getting each of the ends of the refrigerator backing to fit took careful placement but the flexibility of the metal makes it easier/possible.
When the back of the collector is lined up squarely top the window frame, use 6 screws to seal the collector. Since the window frame was narrow, careful attention is required when tightening.
Once the collector has been sealed, use the 2x4 to make two footings for the collector. The latitude where this system was constructed was 36 degrees so, the angle of the tilt of the collector was made to equal the altitude. Use the protractor, tape measure, and saw to make the footings. Attach to the back with the several wood screws.
