Staple the fabric stretched over one of the two freshwater recovery frames, without the sides touching the vertical edges of the frame. The fabric is stapled between the top of the frame and the reinforcement! Be careful not to make a hole in the bottom of the frame! Secure the two frames facing each other by enclosing the fabric in between. Allow 10 centimeters of fabric exceed at the bottom and top of the frames. Provide feet to keep the desalinator up. Finally, fix the reflectors to the whole so that you can tilt them according to the height of the sun. They will be held in position using twine.
