ONE-PIECE DOOR
SECTIONAL DOOR
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service. Garage doors, door springs, cables,
pulleys, brackets and their hardware are under
extreme tension and can cause serious injury
or death. Do not try to loosen, move or adjust
them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked) position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
WARNING
CAUTION
WARNING
WARNING
CAUTION
WARNING
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required by referring to the
lists on page 4 or page 5.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.

Before you begin, survey your garage area to see
whether any of the conditions below apply to your
installation.
Based on your particular requirements, there are
several installation steps which might call for materials
and/or hardware not included in the carton.
• Step 1, page 12 - Look at the wall or ceiling above
the garage door. The header bracket
must be
securely fastened to structural supports.
• Step 5, page 17 - Do you have a finished ceiling in
your garage? If so, a support bracket and
additional fastening hardware may be required.
• Safety reversing sensor, page 21 - Depending
upon garage construction, wood blocks may need
to be fastened to mounting locations before
sensors are installed.
• Step 10, page 22 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Step 11, page 24 - Do you have a steel, aluminum,
fiberglass or glass panel door? If so, horizontal
and vertical reinforcement is required.
• Look at the garage door where it meets the floor.
It must close on the floor all the way across.
Otherwise, the safety reverse system may not
work properly. See page 30. Floor or door should
be repaired.
• If your door is more than 7 feet high, see longer
rails available on page 38.
SECTIONAL Door Installation
• The opener can be installed within 2 feet of the left
or right of the door center if there is a torsion spring
or center bearing plate in the way of the header
bracket or door bracket area. If your door has
extension springs, the opener must be installed
in the center of the door. See pages 12 and 24.
• Do you have an access door in addition to the
garage door? If not, Model 7702CB Outside Quick
Release is required. See page 38.
