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
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.

IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS
2. Install only on a properly balanced and lubricated garage door. An improperly balanced door
may not reverse and could result in severe injury or death. Repairs to cables, spring assemblies
and other hardware must be made by a professional service person before installing opener.
3. Disable all locks and remove all ropes connected to the garage door before installing the opener.
Ropes connected to a garage door can cause entanglement and death.
4. If possible, install door opener 7 feet or more above floor with the manual release handle
mounted 6 feet above the floor.
5. Do not connect the opener to power source until instructed to do so.
6. 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.
7. Install the User Safety Instruction Label on the wall adjacent to the control button and the
Maintenance Instruction Label in a prominent location on the inside of the garage door.
8. Upon completion of the installation, the door must reverse when it comes in contact with a one-
inch high object (or a 2x4 laid flat) on the floor.
9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or
loose clothing can be caught in the mechanism of the garage door or the opener.

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 multi-function door control is typically attached
directly to the wall. For pre-wired installations (as in
new home construction) it can be mounted to a
standard single gang box. See illustrations.
• 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 door control as follows: white wire to 2
and white/red wire to 1.
(NOTE: After installation, a
green indicator light behind the white translucent
cover will indicate proper connection. If not lit, the
Lock and Light features will not function (reverse
wires to correct).
• Before mounting, remove the white cover by gently
pushing both thumbs against the upper corners of
the cover on the
back side of the door control (see
illustration).
•
For standard wall mount, mark the wall about 1-1/4"
up the centerline from the bottom of the door control.
Install a 6ABx1-1/4" self-tapping screw at this point,
allowing about 1/8" to protrude from the wall. Slip the
lower part of the door control over the screw head
and adjust for snug fit. Drill and install the top screw
with care to avoid cracking the plastic housing.
Do not
overtighten.
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.
•
For pre-wired installations, partially install a 6-32x1"
machine screw into the bottom of the gang box,
allowing about 1/8" to protrude. Slip the lower part of
the door control over the screw head and adjust for
snug fit. Install top screw with care to avoid cracking
plastic housing.
Do not overtighten.
• Connect the bell wire to the opener terminal screws
as follows: white to 2 and white/red to 1.
• Replace the cover by inserting bottom tabs and
snapping into place. To remove the cover after
mounting, gently pry at the top with a paper clip or
small flat head screwdriver.

Attach the Manual 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 manual
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.
