Instruction manual

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. Determine 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.
