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.

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

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 1702E 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.

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.
• ALWAYS keep gate in good repair and make sure it moves
freely. An improperly maintained gate may NOT reverse when
required and could result in SEVERE PERSONAL INJURY or
DEATH.

ASSEMBLY STEP 1
For Sectional and One-Piece Doors ONLY
Assemble the Rail and Attach the
Cable Pulley Bracket
To avoid installation difficulties, do not run the garage
door opener until instructed to do so.
1. Place the 3 rail sections on a flat surface for assembly.
The end sections are identical. The
center section must be positioned with
the braces against the end sections as
shown. Make sure the “directional arrow”
on the center section is pointing toward
the front (to door). Study the illustration
carefully.
2. Bolt rail sections together with the
hardware illustrated and from the
direction indicated. (When assembled,
rail has a front-to-back position as
shown.)
NOTE: If rail is not assembled exactly as shown, trolley
will not travel smoothly along length of rail or it will hit
against nuts.
3. Position the cable pulley bracket on the front end of the
rail as shown. Fasten securely with the hardware
provided.
NOTE: When tightening the bolts be sure to keep
bracket parallel to the rail. Otherwise, the rail may bow
when the opener is operated.
