IMPORTANT INSTALLATION INSTRUCTIONS

WARNING —
To reduce the risk of severe injury or death:

1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.

2. Install only on a properly balanced garage door. An improperly balanced door has the potential to inflict severe
injury. Have a qualified service person make repairs to cables, spring assemblies, and other hardware before
installing the opener.

3. Remove all ropes and remove or make inoperative all locks connected to the garage door before installing opener.

4. Where possible, install the door opener 7 feet or more above the floor. For products having an emergency release,
mount the emergency release within reach, but at least 6 feet above the floor and avoiding contact with vehicles to
avoid accidental release.

5. Do not connect the opener to source of power until instructed to do so.

6. Locate the control button: (a) within sight of door, (b) at a minimum height of 5 feet so small children are not able to
reach it, and (c) away from all moving parts of the door.

7. Install the Entrapment Warning Label next to the wall-mount control button in a prominent location. In case the
adhesive does not adhere on the surface, the label should be attached to the surface by mechanical means.

8. After installing the opener, the door must reverse when it contacts a 1-1/2-inch high object (or a 2 by 4 board laid
flat) on the floor.

IMPORTANT SAFETY INSTRUCTIONS

WARNING —
To reduce the risk of severe injury or death:

1. READ AND FOLLOW ALL INSTRUCTIONS.

2. Never let children operate or play with door controls. Keep the remote control away from children.

3. Always keep the moving door in sight and away from people and objects until it is completely closed. NO ONE
SHOULD CROSS THE PATH OF THE MOVING DOOR.

4. NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR.

5. Test door opener monthly. The garage door MUST reverse on contact with a 1-1/2-inch high object (or a 2 by 4
board laid flat) on the floor. After adjusting either the force or the limit of travel, retest the door opener. Failure to
adjust the opener properly increases the risk of severe injury or death.

6. Use the emergency release only when the door is closed. Use caution when using this release with the door open.
Weak or broken springs are capable of increasing the rate of door closure and increasing the risk of severe injury or
death.

7. KEEP GARAGE DOORS PROPERLY BALANCED. See owner’s manual. An improperly balanced door increases
the risk of severe injury or death. Have a qualified service person make repairs to cables, spring assemblies, and
other hardware.

SAVE THESE INSTRUCTIONS.

Mounting Header Bracket

To Install Header Bracket
Note: Installation procedures may vary according to door

type.

1. While inside your garage, close the door and mark the
vertical centerline of the garage door. Extend the line onto
the header wall above the door spring.

2. Open the door to the highest point of travel. Mark a line on
the header wall 2“ (5cm) above the highest point of travel.

Note: DO NOT install the Header Bracket over drywall. In some
installations, it may be necessary to install a 2x4 across two wall
studs to create a suitable location for the Header Bracket.

If installing into masonry, use concrete anchors (not provided).

Wall-Mounting

As shown in Fig.2, place the Header Bracket on the vertical
centerline in direction shown.

Mark and drill two 3/16” holes. Fasten the Header Bracket
securely to a structural support using two 5/16” x 2-1/2” Lag
Screws.

Alternative Ceiling-Mounting

Ceiling-mounting is suggested ONLY when clearance is minimal.
Extend the vertical centerline onto the ceiling as shown in Fig.3.

Center the Header Bracket on the vertical mark, no more than
6” (15cm) from the header wall. Mark and drill holes to fasten the
Header Bracket securely to a structural support.

WARNING

To prevent SERIOUS INJURY:

- DO NOT connect power until instructed.

- The Header Bracket MUST be SECURELY fastened to the structural support on the mounting wall or
ceiling, otherwise the door may not reverse when required. DO NOT install the Header Bracket over drywall.

- Concrete anchors MUST be used when mounting the Header Bracket into masonry.

- NEVER try to loosen, move or adjust garage door springs, cables, Pulleys, Brackets, or hardware, all of
which are under EXTREME tension.

To Attach the Opener to the Header Bracket

1. As shown in Fig.1, use the packaging carton as temporary
support for the Opener. Place the Opener on carton to
prevent damage.

2. Align the mounting hole on the header rail to the mounting
hole on the Header Bracket.

3. Connect the Header Rail and the Door Bracket together
with a 5/16” x 2-1/4” Clevis Pin and lock it in place with a

To mount the Door Bracket
Note: Some door reinforcement kits may provide direct

attachment of the door arm to the reinforcement bracket. If you
have a door reinforcement bracket with this option, skip this step
and proceed with the next step “Mounting Opener to Ceiling”.

1. Position the Door Bracket on the centerline of the door
approximately 2” - 4” (5-10cm) below the top edge of the
door, as shown in Fig.2.

2. Depending on the construction of your door, install using
one of the steps shown if Fig. 3 below:

For steel / lightweight doors with vertical steel
reinforcements / factory reinforced.

(a) Mark and drill two 3/16” holes. Make sure not to drill
through the garage door. Secure the Door Bracket with two
1/4” x 1” Self-Threading Screws (provided) as shown in
Fig.3(a).

(b) Alternative installation: Drill two 5/16” holes through the
door. Secure the Door Bracket using two 5/16” Bolts, lock
washers and nuts (not provided) as shown in Fig.3(b). The
length of bolts will depend on the thickness of your door.

Wood door

(c) Mark and drill two 5/16” holes through the garage door.
Secure the Door Bracket using two 5/16” carriage bolts,
washers and nuts (not provided) as shown in Fig.3(c). The
