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.
Tools needed
During assembly, installation and adjustment of the
opener, instructions will call for hand tools as
illustrated below.

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.

GATE INSTALLATIONS
•It is recommended that you attach fine mesh or
screening across the inside of swinging or sliding
gates in order to prevent intruders from reaching
through the bars and releasing the trolley from the
door arm or pressing the door control button.
•The opener must be protected from rain and/or
moisture.
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing gate.
• Activate gate ONLY when the gate is in full view and
free from any obstructions.
• ALWAYS keep gate in sight until completely closed.
NEVER permit anyone to cross the path of the moving
gate.
