Care must be taken to prevent injury or death during installation and operation of the garage door and garage door operator. 1 Check the Door Balance 1 From outside the garage, slowly open the door all the way, and then close it all the way. Notice if there is any binding, sticking or rubbing. The door should move smoothly in both directions. 2 Raise the garage door about halfway up. Carefully release the door and see if the door balances. It should stay in place. Close the door. IMPORTANT: If the garage door is unbalanced or the door travel isn’t smooth, have a qualified garage door professional adjust or repair the door. 2 Attach the Rail to the Operator 1 Place the operator head on the garage floor with cardboard underneath it to protect the finish. 2 Align the rail over the center of the operator head. 3 Be sure the flat on the sprocket lines up with the flat on the drive shaft. 4 Slide the sprocket onto the shaft. 5 Attach the rail to the operator head by installing four .-20 x .” bolts. 6 Tighten the four bolts in the order shown with a 7/16” socket. 3 Locate the Header Bracket Position 1 Close the door. 2 From inside the garage, use a pencil to mark the vertical centerline of the door on the header wall and on the top panel of the door. 3 Examine the area above the center of the door on the door header wall for a header bracket mounting location. 4 Open the door to the high-rise point (the point where the top edge of the door is highest above the floor) and measure the distance to the floor. 5 Close the door and use a pencil to mark the header wall 1” above the measured high-rise point. NOTE: In some installations, the header bracket location will be higher than the door header. This will require adding a 2x4 (or larger) cross piece to the wall studs to provide a mounting location for the header bracket. Use lag screws (not supplied) to attach the 2x4 to the studs. 6 On doors with low headroom, the header bracket can be attached to the ceiling up to 6” back from the header wall (see next step). 4 Install the Header Bracket Attaching the Header Bracket to the Wall 1 Hold the header bracket on the center line drawn above the door with the bottom edge of the bracket on the line marked above the high-rise point. 2 Use a pencil to mark the two bracket holes. 3 Drill two 3/16” pilot holes about 2” deep. 4 Use a .” socket to fasten the bracket with two 5/16” x 2” lag screws. Attaching the Header Bracket to the Ceiling NOTE: On a finished ceiling, be sure there is a joist to fasten to under the sheetrock where the header bracket will be located (use a stud finder). If there is none, install a 2x4 cross piece between the two closest joists to fasten the header bracket onto. 1 Extend the center line drawn on the header wall along the ceiling. 2 Hold the bracket on the center line with the edge of the bracket no further than 6” from the header wall. 3 Use a pencil to mark the two bracket holes. 4 Drill two 3/16” pilot holes about 2” deep. 5 Use a .” socket to fasten the bracket with two 5/16” x 2” lag screws. 5 Connect the Rail to the Header Bracket 1 Place assembled operator on the empty carton on the floor with rail towards the door. 2 Insert the end of the rail into header bracket. 3 Insert the 5/16” x 2-3/8” clevis pin through header bracket and rail. 4 Secure the clevis pin with the hitch pin. 6 Hang the Operator Installation requirements vary with garage construction. Hanging brackets should be angled to provide rigid support. Hanging material is not provided. Angle iron and lag screws are recommended. DO NOT USE NAILS. Following are typical operator hanging methods. Certain installations will require improvised methods. 1 Raise the operator head and set it on top of a stepladder (use extra spacers on top of ladder if it isn’t tall enough). 2 Carefully open the door to the full up position. Lay a 2x4 across the top section of the door as a spacer. Adjust the operator height until the rail touches the spacer. The rail should be close to level. 3 Center the operator head and rail with the centerline mark on the top of the door. 4 For finished ceilings only: An angle iron cross piece between the two closest joists above the operator will be required. Mark mounting hole locations, drill pilot holes and attach the piece with two lag screws (not supplied). 5 Measure the distance from each of the operator’s hanging tabs to the ceiling joists or angle iron cross piece. 6 Cut two angle iron pieces to the required lengths for hanging brackets. Bend brackets if required. • For unfinished ceilings: Hold each bracket in place and use a pencil to mark the locations where they will be attached to the joists, drill pilot holes and attach the pieces with two lag screws (not supplied). • For finished ceilings with an angle iron cross piece: Attach the two hanging brackets to the cross piece with two bolts and two keps nuts (not supplied). 7 Attach operator to hanging brackets using two 5/16-18 x 1” hex bolts and two 5/1...
