SECTIONAL DOOR ONE-PIECE 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.
CAUTION
WARNING
You'll Need Tools
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.

Position the Opener
Follow instructions which apply to your door
type as illustrated. To prevent damage to steel, aluminum,
fiberglass or glass panel doors, do not rest the
opener on the door without using a 2x4.
SECTIONAL Door & ONE-PIECE Door with Track
A 2x4 laid flat 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 2x4 laid flat
on the top section beneath the T-rail.
If the top panel hits the trolley when you raise
the door, pull down on the trolley release arm to
disconnect the inner and outer sections. The
trolley can remain disconnected until Step 12 is
completed.

• 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 opener
to the same distance as the door from the floor (it
will be at a slight angle as shown).
• The top of the door should be level with the top of
the opener. Do not position the opener more than
2" above this point.

Installation Step 5
Hang the Opener
Two representative installations are shown.
Yours may be different. Hanging brackets should
be angled, Figure 1, to provide rigid support. On
finished ceilings, Figure 2, attach a sturdy metal
bracket to structural supports before installing the
opener. The bracket and fastening hardware are not
supplied.
• Measure the distance from each side of the opener
to the structural support.
• Cut both pieces of the hanging bracket to required
lengths.
• Drill 3/16" pilot holes in the structural supports.
• Attach one end of each bracket to a support with
5/16"x1-7/8" lag screws.
• Fasten the opener to the hanging brackets with
5/16"-18x7/8" screws, lock washers and nuts.
• Check to make sure the T-rail is centered over the
door (or in line with the header bracket if the
bracket is not centered above the door).
• Remove the 2x4. Operate the door manually. If the
door hits the rail, raise the header bracket.
Grease the top and underside
of the rail surface where
the trolley slides with rail
grease.

• Strip 1/4" of insulation from one end of the bell wire;
connect the wire to the two screw terminals on the
back of the Wall Control: white to 2, white/red to 1.
• Locate the Wall Control within sight of the door
at a minimum height of 5 feet where small
children cannot reach, and away from all
moving parts of the door and door hardware.
Fasten the Lighted Push Button Wall Control
securely with 6ABx1-1/2" screws. The console
style uses 6ABx1" screws. If installing into drywall,
drill 5/32" holes and use the anchors provided.
• Run the bell wire up the wall and across the ceiling
to the opener. Use insulated staples to secure the
wire in several places. Be careful not to pierce the
wire with a staple, thereby resulting in a short.
• Receiver terminals and the antenna are located on
the back panel of the opener. Position the antenna
wire as shown.
• Then connect the bell wire to the opener terminal
screws: white to 2; white/red to 1.
• Remember to affix the User Safety Instruction
label to the wall near the Wall Control, and the
Maintenance Instruction label in a prominent
location on the inside of the garage door.
If the label adhesive will not adhere to your garage
wall surface (or becomes loose with time) use tacks
to secure the label alongside the control button.
Page 32 explains how to operate the opener using
the lighted push bar or button.
Do NOT connect the power and operate the
opener at this time. The trolley will travel to the
full open position but will not return to the
close position until the sensor beam is
connected and properly aligned.

Attach the Emergency Release
Rope and Handle
Do not use the red handle to pull the door
open or closed. The rope knot could become
untied and you could fall. Use the emergency
release only to disengage the trolley and, if
possible, only when the door is closed.
Garage doors are heavy. If the door is open
when the handle is pulled, the door could
close inadvertently if it is not properly
balanced. Serious injury may result to persons
under the door. Make sure the doorway is clear
of persons and obstructions before pulling
handle when door is open.
• Thread one end of the rope through the hole in the
top of the red handle so "NOTICE" reads right side
up as shown. Secure with an overhand knot.
The knot should be at least 1" from the end of the
rope to prevent slipping.
• Thread the other end of the rope through the hole in
the release arm of the outer trolley.
• Adjust rope length so the handle is 6 feet above the
floor. Secure with an overhand knot.
If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.
