could fall and injure someone.
Secure opener to structural supports or framing. Do not mount to drywall, plaster, or other such material.
■Position opener head so that rail is lined up with center line of open door.
■Line up hanger brackets (not provided) with ceiling joists or framing to locate where brackets are to be fastened. See Fig. 22.
■Mark location for 5/16" lag screws (not provided), and drill two 3/16" pilot holes.
■Fasten hanger brackets to joists using lag screws.
■If garage framing supports are not visible, attach a length of perforated angle or a 2x4 to the ceiling, securing it to the hidden joists with lag screws long enough to fasten firmly to garage framing (extra hardware items not pro- vided). Then, attach one end of hanger brackets to the perforated angle or 2x4 mounted to ceiling. Attach other end of hanger brackets to opener’s chassis angle iron. See Fig. 23 for alternate mounting methods.
■Once opener is securely fastened in position, remove wood blocks and temporary supports and lower door. Check door for proper operation and clearance by manu- ally moving door to full open and closed position. If door hits rail at any point, raise opener head slightly higher and
NOTE: To provide additional support for rails 13’ length and longer, use optional support bracket. (Accessories p.28)
■Measure the rail’s overall span. Bracket is located on 1/3rd of the overall rail span from the door header bracket end. See Fig. 24
■Place support bracket over rail (close side) on a diagonal. Make sure support securement clamps clear rail sides.
