Things to consider if you are planning to “do-it-yourself.”
Whether you are replacing an existing garage door operator or installing an operator in your
garage for the first time, there are some pre-installation issues which need to be addressed.
They are as follows:
The Overhead Door Corporation recommends that you read and fully understand all
information and instructions contained herein before choosing a
“ do-it-yourself ”
installation. Any questions should be directed to the Overhead Door Corporation or an
authorized Overhead Door Dealer.
6To avoid damage to your door and/or
operator, make sure you disable any door
locks prior to installing your operator.
PRE-INSTALLATION CHECK LIST FOR HELP-1.800.929.3667 OR OVERHEADDOOR.COM
1Check your ceiling where the power
head of your new unit will be mounted.
Plan how you will be mounting the power head.
It is possible that ceiling joists may not be in the
exact position needed with respect to the garage
door operator. It may be necessary to add an
additional bracket and
fasteners (not included
with your new door operator kit).
2Check the wall directly above the garage
door.The door operator’s header bracket
must be securely fastened to this wall. Ensure
that the structure will provide a strong mounting
location.
3Check to see if the mounting location
for the Safe-T-Beam®System (STB)is
clear from obstruction and has a wood
surface available for attaching the STB
brackets.The brackets may be attached to
concrete if necessary but extra tools and special
fasteners (not supplied) will be required.
NOTE: 1-1/2" STB bracket adapters are available
through your local Overhead Door Dealer.
4Is your garage door made of
light-weight steel, aluminum, fiberglass
or glass panels?Additional support bracing
must be added to these type doors. If this is the
case, please contact the door distributor or
manufacturer so that they can furnish you with a
“bracing kit.”
7Ensure that your door is properly balanced
and moving freely. SEE WARNING BELOW.
If your door sticks, binds, or is out of
balance, have it adjusted by a professional.
Door springs, cables, pulleys, brackets and
associated hardware are under extreme
tension and can cause serious injury or
death.
WARNING
(The issue numbers below refer to the circled numbers in the illustrations on page 5.)
8(NOT SHOWN) If your garage does not have
aseparate entry door,you should consider
an emergency release kit (GER-2)(page 34) for
installation on your garage door. Contact Customer
Service or visit www.overheaddoor.com.
DO NOT USE AN EXTENSION CORD!
Extension cords can cause dangerous
overheating conditions.
DO NOT USE A PORTABLE GENERATOR!
This product is designed to operate on
standard house current. Do not use
alternate power supplies.
WARNING
5You need a 110-120 Volt power supply
available.The outlet should be no more than
3feet from the power head once it is mounted. (The
cord is 4 ft. in length.) SEE WARNING BELOW.
Homelink®is a universal
transceiver (a combined
transmitter and receiver), that provides a
convenient way to replace up to three hand-held
radio-frequency (RF) transmitters used to

SECT 2—INSTALLATION FOR HELP-1.800.929.3667 OR OVERHEADDOOR.COM
NOTE: There are differences in installations
depending on which type of door you have.
These differences are explained throughout
this section. Please note those steps which are
applicable to your particular door.
REFER TO PAGES 2 & 3.
There are two basic types of residential garage
doors. They are:
SECTIONAL DOORS—divided into a set of
narrow panels (usually four) connected by
hinges, so door can “bend” as it rides on a
curved track.
1-PIECE DOORS—consist of one large
panel and swivel on large spring-loaded hinges
on each side of door.
1. Determining header bracket location.
• Find center of door from side to side.
–Measure overall width of door.
(example: 16 feet)
– Divide overall width by 2.
(example: 16÷2 = 8 feet)
• Measure this distance from side of door and
draw a pencil line vertically from the top of
the door down approximately 1 foot. This is
the centerline. Fig. 2-1.
–Continue marking centerline on wall
above door from top of door up
approximately 1 foot. Fig. 2-1.

Some older doors may have
extension springs.

INSTALLATION FOR HELP-1.800.929.3667 OR OVERHEADDOOR.COM
2. Finding highest point of travel.
• While raising garage door manually, watch
top edge of door to see where it reaches its
highest point. This is called “highest point of
travel.” Fig. 2-2.
•A locking pliers can be used to hold the
door in position by clamping it onto the rail.
(A stool, chair, table or any object that can
safely support door will work.) Fig. 2-3.
– With door held partly open (at its “highest
point”), measure distance from top edge
to the floor.
• Remove support and gently lower door.
• Mark “highest point of travel” at centerline
on wall above door. Fig. 2-3.
NOTE: Following step depends on type of door.
3. Final header bracket mounting location.
• For SECTIONAL DOORS—
add 2-1/2 inches to “highest point of travel”
and mark this height on centerline. Fig. 2-3.
•For ONE-PIECE DOORS—
add 6 inches to “highest point of travel” and
mark this height on centerline. Fig. 2-4.

NOTE: If torsion spring interferes with your
final location, mark bracket location 2-1/2" or
6" above torsion spring depending on garage
door type.
4. Check mounting location for strength.
Header bracket must be attached to
framework of garage.
Fig. 2-5.
• If final header bracket position is on garage
door header, continue with step 5.
• If final header bracket position is above
garage door header, a mounting plate must
be installed and mounting location must be
remarked before continuing with step 5.
Fig. 2-5.
•If your garage wall is finished (covered with
drywall), continue with step 5.
5. Mounting preparation.
•Hold bracket against wall where final header
bracket height crosses centerline.
•Make sure flange where boom strap
attaches, is on centerline. Fig. 2-6.
•Mark screw hole locations.
– If your wall is finished, take a small “finish
nail” and gently tap it through drywall
where you have marked screw holes to
find out if there is wood behind mounting
location. If your marked location is solid,
continue with step 6.
– If your marked mounting location is not
solid, a mounting plate must be installed
and mounting location remarked before
continuing. Fig. 2-7 and Fig. 2-5.
6. Mount header bracket [20].
•Drill 5/32 inch pilot holes at marked screw
hole locations.
•Fasten header bracket using 3 lag
screws [22].
