Attach the Mounting Assembly to the Ceiling (Option 2) You can hang the screen from a flat (not sloped) ceiling. If your ceiling has wooden joists, this option is possible only if the joists run toward the screen. If they run across the width of your room, you won't be able to hang the screen safely from the ceiling. Also, make sure your ceiling is level before starting-if it isn't, the screen will not hang properly. Note These steps describe how to attach the screen to a ceiling with wooden joists. If you have a solid concrete ceiling, you can also attach it using the included concrete anchor bolts. 1 Slide the ceiling-mounting brackets onto the alignment bar, as shown below. Insert the 4 small screws into the face of the brackets. Loosely tighten the screws to keep the brackets from sliding off the bar. Slide brackets onto bar Insert screws 2 Determine where you want to hang the screen. Hold the mounting assembly against the ceiling and mark its approximate location. 3 Use a stud finder to locate three joists, one near each end of the mounting assembly and one near the middle. Joists are normally spaced 16 inches on center. Mark the exact center of each joist. Warning You must find the exact center of the joist, or you won't be able to attach the screen securely. 4 Make sure the mounting assembly is aligned properly, so it goes straight across the room. (Measure from the wall behind the screen to ensure that the brackets are straight.) Attach one of the end brackets to the ceiling with two wood screws. Joist Attach bracket to joist with wood screws 5 Attach the bracket at the other end. 6 Use a level to make sure the alignment bar is level. If necessary, insert shims or spacers between the bracket and the ceiling to level the bar. Caution The bar must be level, or the screen will not deploy properly. A slight tilt may cause screen failure over time. 24
