Mounting the Assembled Garage Door Opener

Mounting the assembled garage door opener is done in three main steps:

- Attach the Rail to the Wall

- Attach the Motor Assem bly to the Ceiling

- Attach the Door Brackets to the Garage Door and Garage Door Bracket

Attach the Rail to the Wall – Sectional & One Piece Doors

To avoid injury or death:

- Be su re to securely mount the garage door opener.

- Never touch any moving part while the garage door opener is in operation.

- Do not attempt to fix the garage door opener if it jams or malfunctions. Call a DGO installation professional for

assistance.

1. T h e fi rst step is to d et e rm ine wh e re to a t tach t h e wall b racket. How you do this depends on whether you
have a sectional garage door on rails or a one piece garage door.

If you have a sectional garage door, do the foll owing:

a. Open the door to the highest point of travel. In the center of the wall above the door, draw a

horizontal line 2” above the high point of the garage door. This height will provide travel clearance for
the top edge of the door.

12

1/2 HP Chain Drive Garage Door Opener

If you have a o

ne-piece garage door

, do the following:

a. Open your door to the highest point of travel as shown. Measure the distance from the top of the door to the

floor. Subtract the actual height of the door. Add 8” to the remainder. For example:

91” = Distance from top of door at highest point of travel to floor

87” = Actual height of door

91” – 87” = 4” remainder

4” + 8” = 12”

d. Close the door and draw an intersecting horizontal line on the header wall at the determined height from

the top of the closed door.

13

1/2 HP Chain Drive Garage Door Opener

NOTE: If there is not enough room or if there is no way to secure the garage door opener to the wall

over the spring, you can secure it to the ceiling above the door. Mark the center of the ceiling, no
more than 6 inches from the wall.

2. Mount the Header Bracket with two lag bolts provided to either the wall or the ceiling

OR

14

1/2 HP Chain Drive Garage Door Opener

3. Lay the rail against the wall (or ceiling) mount and rest the motor assembly on something tall such as a ladder

which is enough to support the rail so it does not touch the garage door spring. Some garage doors require this

height to attach the rail to the header bracket. Other doors which do not have the door spring located directly

above the garage door, may allow you to rest the opener on the carton it was shipped in to ease assembly.

4. Then attach the rail front to the wall mount with the Ø8-35mm clevis pin and split pin as shown.

15

If your door passes both of these tests, no limit adjustments are necessary. Go to next section on Testing and

Adjusting the Safety Reversing Sensors

29

1/2 HP Chain Drive Garage Door Opener

Adj ust Range of M otion

To avoid injury or death:

- Be sure correctly adjust the door range of motion. Failure to correctly adjust the door range of motion may result

in malfunction of the emergency reverse system, which can result in damage to property, personal injury and

death.

- Do not stand under the garage door opener when adjusting the door range of motion.

If adjustments are needed, follow the adjustment procedures outlined below:

Check each of the following:

1. If the door does not open completely, increase the "up travel" distance by rotating the adjusting screw
clockwise. Locate the two adjustments on the bottom center of the motor housing:

Use a flathead screwdriver to make limit adjustments. Turn the UP limit adjustment screw clockwise as
needed. One full turn equals 2” of travel. Run the opener through a complete travel cycl e after each
adjustment and repeat as needed to fine tune the range of motion.

2. If the door does not close completely, increase "down travel" distance. Turn the down limit adjustment
screw counterclockwise. . Locate the two adjustments on the bottom center of the motor housing:

Use a flat head screwdriver to make limit adjustments. Turn the DOWN limit adjustment screw clockwise
as needed. One full turn equals 2” of travel. Run the opener through a complete travel cycle after each

adjustment and repeat as needed to fine tune the range of motion.

3. If the opener reverses when it reaches its fully closed position, decrease down travel by adjusting the
downward travel limit screw clockwise.

4. If the door reverses when closing and there is no visible interference to the travel cycle, check the door
for binding. Pull the trolley emergency release handle and manually open and close the door. If the door

is binding or unbalanced, call a trained garage door technician. If the door is not binding or unbalanced,
adjust the Down force. See next section:

1. Press the remote control push button to open the door.

2. Place an empty cardboard box carton in the path of the door.

3. Press the remote control push button to close the door. The door should not move. If it does, contact
technical support for instructions.

4. Re m ove the box a n d p ress the re m ote con trol p u sh b u t ton to cl ose th e door. Place the box in the door's
path. The door should automatically reverse. If it doesn't, contact technical support for instructions.

D) Testing and Adjusting Door Force

To avoid injury or death:

- Be sure correctly adjust the door force controls. Failure to correctly adjust the door force controls may result in

malfunction of the emergency reverse system, which can result in damage to property, personal injury and death.

- Do not stand under the garage door opener when adjusting the door force controls.

- After any adjustments are made, test the safety reversal syst e m .

Force adjustment settings regulate the amount of power required to open and close the door. If the force adjustment is

set too light, door travel may be interrupted in the down direction and stops in the up direction. If it is set too heavy, the

door will not emergency reverse fast enough.

Weather conditions can affect the door movement, so occasional adjustment may be needed.

1. Locate the force adjustment controls on the side panel of the motor unit.

31

1/2 HP Chain Drive Garage Door Opener

The maximum force adjustment range is about ¾ of a complete turn. Do not force controls beyond that

point. Turn force adjustment controls with a screwdriver.

2. Test th e DOWN (cl o se) force. G rasp the door b o ttom wh en th e do or is about halfway through DOWN

(close) travel and try to stop the door. The door should reverse. If the door is hard to hold or doesn’t
reverse, DECREASE the DOWN (close) force by turning the control clockwise. Make small

adj u stm ents un ti l t h e d o or c o m pl ete s a close c ycl e . After each adjustment, run the opener through a
com plete trave l cycl e . Do n o t i ncre a se the fo rce beyond th e m inimum amount required to close the

door.

3. Test th e UP (open) force. If the door does not open ful l y INCREASE UP (Open) force by turning the

control clockwise. Make small adjustments until door opens completely. Readjust the UP limit if
necessary. After each adjustment, run the opener through a complete travel cycle.

E) Testing and Adjusting the Safety Reverse Feature

To avoid injury or death:

- Be sure correctly adjust the safety reversal system. Failure to correctly adjust the door force controls may result in

malfunction of the emergency reverse system, which can result in damage to property, personal injury and death.

- Do not stand under the garage door opener when adjusting the safety reversal system.

Your Garage Door Opener comes with a safety feature that makes the door automatically reverse if the door

encounters an object before it fully closes.

1. With the door fully open, place a one-inch board (or a 2x4 laid flat) on the floor, cenetered under the
garage door. Operate the door in the down direction. The door must reverse on striking the obstruction.

2. If the door stops shy of the obstruction, it is not traveling far enough in the down direction. Increase the
DO WN li m it by turn i ng t h e DOWN l imi t a d j ustm e n t screw countercl ockwise ¼ turn. Repeat until it hits the

board and reverses.

3. If the door stops on the obstruction but does not reverse, reduce the DOWN force by turning the
adjustment screw counterclockwise ¼ turn. Repeat until it automatically reverses when it hits the board.
