WALL MOUNTING BRACKET AND OPERATOR INSTALLATION:
NOTE: Trolley type operators should generally be mounted directly over the center of the door and
the trolley tracks should clear the tracks by 2-1/2" ( 6.5 cm). However, if interfering structures or
other reasons do not allow for centered mounting, it is possible to install it up to 18" off-center for
torsion spring doors.
1. Locate the center of door by measuring door width and mark a vertical line above the door.
2. Detern1ine the highest point of door travel by manually opening the door. Using a
carpenter's level, project a line from where the top section of door reaches its highest point.
Mark the spot where this line (high arc) intersects with the vertical line drawn earlier.

3. Mount a wood block or angle iron to the wall above the door opening as shown below. The wall
mounting bracket has 3 holes for anchoring to wood block or angle iron. Bracket should be
centered with door and positioned so that these holes are 2-1/2" (6.5 cm) above the high arc
line of door. Secure wall mounting bracket using suitable hardware.

4. While allowing motor to rest on floor, raise front end of track assembly and secure (but not tighten) to
wall mounting brackets with 3/8" bolts and nuts provided.
5. Swing the operator and track assembly above the level of the door tracks and temporarily secure in
place with rope or chain. Carefully open door. Align operator and rails with center of door.
Using the door as support, shim the operator so that there is 3" (7.5cm) clearance between
door and bottom of operator. Tighten wall mounting bracket bolts.

6. Install hanging brackets (braces) from ceiling or structure to any of the 3/8" holes located on
operator frame. For tracks over J 4' long it is recommended to install braces to the tracks at
4'(1.2m) to 5' (1.5m) from operator.
TROLLEY ARM INSTALLATION
I. Manually close door to fully closed position. Slide trolley carriage towards front idler and latch trolley
arm to carriage spring pin by pulling on rope. When installed the open side of notch should
face the door.
2. Using 3/8" bolts and nuts provided, align the mounting holes of straight arm and curved arm so that
pivot bolt on door bracket is in line with the top rollers of the door. Align door bracket with
centerline of door and secure to door using suitable hardware.
