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 garage
door BEFORE installing and operating garage 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 reinforcement 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 6 mm. Otherwise, the safety reversal
system may NOT work properly.
• The floor or the garage door MUST be repaired to eliminate
the gap.

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:
• Header bracket MUST be RIGIDLY fastened to structural
support on header wall or ceiling, otherwise garage door
might NOT reverse when required. DO NOT install header
bracket over drywall.
• Concrete anchors MUST be used if mounting header bracket
or 38 mm board into masonry.
• NEVER try to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, ALL of which are
under EXTREME tension.
• ALWAYS call a trained door systems technician if garage door
binds, sticks, or is out of balance. An unbalanced garage door
might NOT reverse when required.

ONE-PIECE DOOR WITHOUT TRACK
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.

INSTALLATION STEP 2
Install the Header Bracket
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.
