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.
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.
WARNING CAUTIONCAUTION
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.

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.

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"-18x1-7/8" 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.

Installation Step 6
Install the Premium Control Console
18
Do not connect to live electrical wiring.
Connect only to 24 Volt low voltage wires.
Connection to live wires or higher voltage may
cause serious injury from shock, burn or
electrocution.
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death.
Install the door control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware, but where the garage door is visible.
Do not allow children to operate the push
button(s) or the remote control(s).
A moving garage door could injure someone
under it. Activate the opener only when the
door is properly adjusted, you can see it clearly,
and there are no obstructions to door travel.
WARNING
Locate the door 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.
The door control is typically attached directly to the
wall. If installing into drywall, drill 5/32" holes and
use the anchors provided. For pre-wired installations
(as in new home construction), Console models
may be mounted to a standard single gang box
(Figure 2).
1.Strip 1/4" of insulation from one end of the bell
wire and connect it to the two screw terminals on
the back of the door control: white to 2, and
white/red to 1.
2.Pry off cover along one side with a screwdriver
blade (see Figure 1). Fasten with 6ABx1-1/4" self-
tapping screws (standard installation) or 6-32x1"
machine screws (pre-wired installation) as
follows:
• Install bottom screw, allowing 1/8" to protrude
above wall surface.
• Position bottom of door control on screw head
and slide down to secure. Adjust screw for snug
fit.
• Drill and install top screw with care to avoid
cracking plastic housing. Do not overtighten.
• Insert top tabs and snap on cover.
3. (For standard installation only) 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, creating a short.
4. Connect the bell wire to the terminal screws on
the opener panel: white to 2; white/red to 1.
5. Position the antenna wire as shown.

Install the lights:
• Install a 75 watt maximum light bulb in each
socket. The lights will turn ON and remain lit for
approximately 4-1/2 minutes when power is
connected. Then the lights will turn OFF.
• If the bulbs burn out prematurely due to vibration,
replace them with standard neck "Garage Door
Opener" bulbs.
Install the lenses:
• Apply slight pressure on the sides of each lens
and slide the tabs into the slots in the side panels.
• For convenience, the lenses may be installed
after Adjustment Step 4 on page 30.
• Reverse the procedure to remove the lenses.
Installation Step 7
Install the Lights and the Lenses
6. Attach the User Safety Instruction label to the wall
near the door control, and the Maintenance
Instruction label in a prominent location on the
inside of the garage door.
Page 32 explains how to use the door control.
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.
See Safety Reversing Sensor instructions
beginning on page 21.
Installation Step 8
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.
