POSITION THE OPENER

Follow instructions which apply to your door type as illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH TRACK
A 2x4 laid flat is convenient for setting an ideal door-to-rail distance.
1. Raise the opener onto a stepladder. You will need help at this point if the
ladder is not tall enough.
2. Open the door all the way and place a 2x4 laid flat on the top section
beneath the rail (Figure 1).
3. If the top section or panel hits the trolley when you raise the door, pull
down on the trolley release arm to disconnect inner and outer sections.
Slide the outer trolley toward the motor unit. The trolley can remain
disconnected until Installation Step 12 is completed.
