To prevent damage to garage door and opener:
• ALWAYS disable locks before installing and operating
the opener.
• ONLY operate garage door opener at 120V, 60 Hz to
avoid malfunction and damage.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if
garage door binds, sticks, or is out of balance. An
unbalanced garage door may not reverse when
required.
• NEVER try to loosen, move or adjust garage door, door
springs, cables, pulleys, brackets or their hardware, all
of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to

door opener to avoid entanglement.
Preparing your garage door
Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
•Complete the following test to make sure your
garage door is balanced and is not sticking or
binding:
1. Lift the door about halfway as shown. Release
the door. If balanced, it should stay in place,
supported entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.

SECTIONAL DOOR INSTALLATION
Planning
Identify the type and height of your garage door.
Survey your garage area to see if any of the
conditions below apply to your installation. Additional
materials may be required. You may find it helpful to
refer back to this page and the accompanying
illustrations as you proceed with the installation of
your opener.
Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 – Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
• Installation Step 5 – Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• Do you have an access door in addition to the
garage door? If not, Model 7702CB Outside Quick
Release is required. See Accessories page.
• Look at the garage door where it meets the floor.
Any gap between the floor and the bottom of the
door must not exceed 6 mm. Otherwise, the safety
reversal system may not work properly. See
Adjustment Step 3. Floor or door should be
repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforce-
ment is required (Installation Step 10).
• The opener should be installed above the center of
the door. If there is a torsion spring or center
bearing plate in the way of the header bracket, it
may be installed within 1.2 m to the left or right of
the door center. See Installation Steps 1 and 10.

Planning (Continued)
ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, refer to
the information relating to sectional doors in
Installation Step 10.
• Depending on your door’s construction, you may
need additional mounting hardware for the door
bracket (Step 10).
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• The gap between the bottom of the garage door and
the floor MUST NOT exceed 6mm. Otherwise, the
safety reversal system may not work properly.
• The floor or the garage door MUST be repaired to
eliminate the gap.

INSTALLATION STEP 1
Determine the Header Bracket
Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your
door.
If your door is a canopy or dual-track style garage
door, a door arm conversion kit is REQUIRED.
Follow the installation instructions included with the
replacement door arm sectional.
SECTIONAL DOOR AND
ONE-PIECE DOOR WITH TRACK
1. Close the door and mark the inside vertical
centerline of the garage door.
2. Extend the line onto the header wall above the
door.
You can fasten the header bracket within 1.2 m
of the left or right of the door center only if a
torsion spring or center bearing plate is in the
way; or you can attach it to the ceiling (see
page 17) when clearance is minimal. (It may be
mounted on the wall upside down if necessary,
to gain approximately 1 cm .)
If you need to install the header bracket on a
38 mm board (on wall or ceiling), use lag screws
(not provided) to securely fasten the 38 mm board
to structural supports as shown here and on
page 17.
3. Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 5 cm above the high point. This height
will provide travel clearance for the top edge of the
door.
Proceed to Step 2, page 18.
To prevent possible SERIOUS INJURY or DEATH:

1. Close the door and mark the inside vertical
centerline of your garage door. Extend the line
onto the header wall above door, as shown.
If headroom clearance is minimal, you can install
the header bracket on the ceiling. (See page 18).
If you need to install the header bracket on a
38 mm board (on wall or ceiling), use lag screws
(not provided) to securely fasten the 38 mm board
to structural supports as shown.
2. 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 20 cm to the remainder. (See Example).
3. Close the door and draw an intersecting horizontal
line on the header wall at the determined height.
NOTE: If the total number of centimeters exceeds
the height available in your garage, use the
maximum height possible, or refer to page 18 for
ceiling installation.

You can attach the header bracket either to the wall
above the garage door, or to the ceiling. Follow the
instructions which will work best for your particular
requirements. Do not install the header bracket
over drywall. If installing into masonry, use
concrete anchors (not provided).
WALL HEADER BRACKET INSTALLATION
• Center the bracket on the vertical centerline with
the bottom edge of the bracket on the horizontal
line as shown (with the arrow pointing toward the
ceiling).
• Mark the vertical set of bracket holes (do not use
the holes designated for ceiling mount). Drill 5 mm
pilot holes and fasten the bracket securely to a
structural support with the hardware provided.

ONE-PIECE DOOR WITHOUT TRACK
• With the door fully open and parallel to the floor,
measure the distance from the floor to the top of
the door.
• Using a stepladder as a support, raise the top of
the opener to this height.
• The top of the door should be level with the top of
the motor unit. Do not position the opener more
than 5 cm above this point.
INSTALLATION STEP 4
Position the Opener
Follow instructions which apply to your door type as
illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH
TRACK
A 38 mm board is convenient for setting an ideal
door-to-T-rail distance.
• Raise the opener onto a stepladder. You will need
help at this point if the ladder is not tall enough.
• Open the door all the way and place a 38 mm
board on the top section beneath the T-rail.
• If the top section or panel hits the trolley when you
raise the door, pull down on the trolley release arm
to disconnect inner and outer sections. Slide the
outer trolley toward the motor unit. The trolley can
remain disconnected until Installation Step 11
is completed.
