Fiberglass,aluminum or lightweight steel garage doors WILLREQUIRE reinforcement BEFORE
installation of door bracket.Contactyour door manufacturer for reinforcementkit.

Figure 1 showsone piece of angle iron as the horizontal
brace. For the vertical brace, 2 pieces ofangle iron are
used tocreate a U-shaped support. The best solution is to
checkwithyour garage door manufacturer for an opener
installation door reinforcementkit.

NOTE: Many door reinforcementkitsprovide for direct
attachment of the clevispin and door arm. In this case you
will not need the door bracket; proceed to the next step.

8.1 Center the door bracket on the previously marked vertical centerline used for the header bracket

installation.Note correct UP placement,as stamped inside the bracket.

8.2 Position the top edge of the bracket 2"-4" (5-10 cm) below the top edge of the door, OR directlybelow

any structural supportacrossthe top of the door.

8.3 Mark,drill holes and install as follows,depending on your door’s construction:

Metal or light weight doors using a vertical angle ironbrace between the door panel support and
the door bracket:

• Drill 3/16" fastening holes. Secure the door bracket using the twoself threading screws (H10).
(Figure 2)

• Alternately, use two 5/16" bolts,lockwashers and nuts(not provided). (Figure 3)

Metal,insulated or light weight factory reinforced doors:

• Drill 3/16" fastening holes. Secure the door bracket using the self-threading screws (H10).
(Figure 4)

NOTE: The 1/4"-14x5/8"self-threading screws are not intended for use on wood doors.

Wood Doors:

• Use top and bottom or side to side door bracketholes.Drill 5/16” holes through the door and
secure bracketwith 5/16"x2" carriage bolts, lock washers and nuts (not provided). (Figure 5)

A horizontal andvertical reinforcement is
needed for lightweight garage doors
(fiberglass, aluminum, steel,doors with glass
panel,etc.) (not provided).
A horizontal reinforcement brace shouldbe
long enoughto be secured to two or three
vertical supports. A verticalreinforcement
brace shouldcover the height of the toppanel.

IMPORTANTINFORMATIONABOUTTHESAFETYREVERSINGSENSORS
The safety reversing sensors must be connectedand aligned correctly before the garage dooropenerwillmove in the down direction.

The sending sensor (with an amber LED) transmitsan invisible light beam to the receiving sensor (witha green LED). Ifan obstruction breaks the light
beam while the door is closing,the door will stop and reverse tothe full open position,and the garage door opener lights will flash 10 times.

NOTE: For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The sleep mode shuts the garage door
opener down until activated. The sleep mode is sequenced with the garage door opener light bulb; as the light bulb turns off the sensor LEDs will turn
off and whenever the garage door opener lights turn on the sensor LEDs will light. The garage door opener will not go into the sleep mode until the
garage door opener has completed 5 cycles upon power up.

When installing the safetyreversing sensors checkthe following:

• Sensorsare installed inside the garage, one on either side of the door.

• Sensorsare facing each other with the lenses aligned and the receiving sensor lens does not receive direct sunlight.

• Sensorsare no more than 6 inches(15 cm) above the floor and the light beam is unobstructed.

1 Connect Power

To preventpossible SERIOUSINJURY or
DEATHfrom electrocution or fire:

• Be sure power is NOT connected to the
opener, and disconnectpower to circuit
BEFORE removing cover to establish
permanent wiring connection.

• Garage door installation and wiring MUST
be in compliance with ALL local electrical
and building codes.

• NEVER use an extension cord, 2-wire
adapter, or change plug in any way tomake
it fit outlet. Be sure the opener is grounded.

To avoid installation difficulties,do not activate the garage dooropenerat this time.

To reduce the risk of electricshock,your garage door opener has a grounding typeplug with a third
grounding pin. This plug will only fit into a grounding type outlet.Ifthe plug doesn’t fit intoyour outlet,
contacta qualified electrician to install the proper outlet.

THERE ARE TWO OPTIONS FOR CONNECTIONPOWER:

OPTION A

TYPICAL WIRING

1.1A Plug in the garage door opener into a grounded outlet.

1.2A DO NOTrun garage door opener at thistime.

OPTION B

Ifpermanent wiring is required by your local code, refer to the following procedure.
To make a permanent connectionthrough the 7/8" hole in the top of the motor unit(according to local
code):

PERMANENT WIRING

1.1B Be sure power isNOT connected to the opener,and disconnect power to circuit.

1.2B Removethe garage door opener cover and set aside.

1.3B Removethe attached green ground terminal.

1.4B Cutblack and whitewires and strip away 1/2" (1 cm)of insulation,3" (7.5 cm) before spade

terminals.

1.5B Removethe power cord from opener.

1.6B Install a conduit or flex cable adapter to the 7/8"hole.

1.7B Run wires through conduit, cut to proper length and strip insulation.

1.8B Attach withwire nutsprovided. Attachthe ground wire to the green ground screw.The opener

mustbe grounded.

1.9B Properly secure wire under plastictiesso that wire does not come in contactwith moving parts.

be aligned by loosening the wing nuts,aligning the
sensors,and tightening the wing nuts.

program the traveland cannot be changed.

PROGRAMMING BUTTONS

To preventdamage to vehicles,be sure fully
open door provides adequate clearance.

TIP: If anything interferes with the door’s

upward travel it will stop. If anything interferes with
the door’s downward travel, it will reverse.

The programming buttonsare located on the

• Safetyreversal systemMUSTbe tested every
month.

• AfterANY adjustmentsare made, the safety

object (or 2x4 laid flat) on the floor.

3 Test the Protector System

Without a properly installed safety reversing
sensor, persons (particularly small children) could
be SERIOUSLY INJUREDor KILLED by a closing
garage door.

2.1 With the door fully open, place a 1-1/2

inch (3.8 cm) board (or a 2x4 laid flat)on
the floor, centered under the garage
door.

3.1 Open the door. Place the garage door

opener carton in the path of the door.

2.2 Press the remote control push button to

close the door. The door MUSTreverse
when itmakes contactwith the board.

3.2 Press the remote control push button to

close the door. The door will not move
more than an inch (2.5 cm),and the
garage door opener lights will flash 10
times.

Ifthe door stops and does not reverse on
the obstruction,the travel needsto be
adjusted (refer to AdjustmentStep 1).

Repeat the test.When the door reverses
upon contactwiththe 1-1/2 inch board,
remove the board and open/closethe
door 3 or 4 timesto testthe adjustment.

Ifthe test continues to fail, call a trained
door systemstechnician.

The garage door opener will not close
froma remote controlif the LED in either

THE PROTECTOR SYSTEM®(SAFETY REVERSING SENSORS)

When properly connected and aligned, the safetyreversing sensors will detectan obstruction in the
path ofthe infrared beam. If an obstruction breaksthe infrared beam while the door is closing,the door
will stop and reverse to full open position, and the opener lightswill flash 10 times.If the door is fully
open, and the safetyreversing sensorsare not installed,or are misaligned, the door will not close from
a remote control. However, you can closethe door if you hold the button on the door control or keyless
entry until the door is fully closed. The safetyreversing sensorsdo no effectthe opening cycle.

added control over the light bulbs on your garage door opener, see the Door Control section.

USING YOUR GARAGE DOOR OPENER

The garage door opener can be activated through a wall-mounted door control, remote control,
wirelesskeylessentry or MyQ™ accessory.

When the door isclosed and the garage door opener is activated the door will open. If the door senses
an obstruction or is interrupted while opening the door will stop.When the door is in any position other
than closed and the garage door opener is activated the door will close.Ifthe garage door opener
