the door.
Do not use disconnect mechanism or manually operate door unless power has been electrically
disconnected.
Keep doors properly maintained. Test door and service regularly. Have a qualified service person
make repairs. An unmaintained door system could cause injury or death.
The owner or users must understand the safety and operation of door system. Insure that this
installation manual be located close to the door system.

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.

LIMIT SWITCH ADJUSTMENTS
Adjustment of door travel is done by moving the limit cams on the threaded shaft. The position
of the 4 limit switches are factory adjusted and should not be altered. The limit switches are:
-
"Open" limit switch:
End of door travel in the fully open position
-
"Closed" limit switch:
End of door travel in the fully closed position
-
"Advanced Open" limit SVlitch:
Used for open/close devices or tinier lo close
features
-
"Advanced Closed" Limit switch:
Used to prevent reversing device from reversing
door when door is almost fully closed.
WARNING

TO REDUCE THE RISK OF INJURY OR DEATH

To adjust door travel:
1.
Open cycle:
Depress cam plate and spin "Open" limit cam away from "Open" limit
switch to increase door travel or spin "Open" limit cam towards the "Open" limit
switch to decrease
door travel. After each adjustment ensure that cam plate fully engages in slots of both
limit nuts.
2.
Adjust "Open" limit cam so that door stops at the desired fully open position.
3.
Close cycle:
Depress cam plate and spin "Close" limit cam away from "Close" limit
switch to increase door travel or spin "Close" limit cam towards the "Close" limit
switch to decrease
door travel. After each adjustment ensure that cam plate fully engages in slots of both
limit nuts.
4.
Adjust "Close" limit cam so that door stops at the desired fully closed position.

- The brake adjustment is factory set and should only require minor adjustment after extensive use.
- Verify brake adjustment by manually holding in solenoid plunger. When brake is properly adjusted,
the brake shoe pads should make complete contact with brake drum with sufficient brake spring
tension to stop and maintain door when solenoid is de-energized. Wben so lenoid is energized, brake
shoes should release from drum with sufficient clearance to avoid contact between shoes and drum.
- To adjust brake tension, tighten (to increase) or loosen (to decrease) nylon lock nut on brake spring
bolt. Observe solenoid during electrical testing of brake. Brake spring tension must be adjusted so
that solenoid should pull and release smoothly and quietly. Too much or too little tension on brake
spring may cause solenoid to bum out.
- To adjust individual brake shoes, loosen nut on brake shoe adjustment bolt and adjust bolt. When
properly adjusted, there should be a small clearance between adjustment bolt and solenoid bracket
when solenoid is de-energized. When solenoid is energized, brake shoes should move away from
drum with sufficient clearance to avoid friction betv:een brake shoe pad and drum. After adjustments
are made be sure to tighten nuts on brake shoe adjustment bolts.
