Instructionsbelow are for attaching the garage door opener directlyto structural supports.

5.1 Measure the distance from each side of themotor unit to

the structural support.

5.2 Cutboth pieces of the hanging bracketto required lengths.

5.3 Drill 3/16" pilot holes in the structural supports.

5.4 Attachone end of each brackettoa support with 5/16"-

18x1-7/8" lag screws (not provided).

5.5 Fasten the opener to the hanging bracketswith5/16"-

18x7/8" hex bolts,lockwashersand nuts.

Metal orlight weight doors usinga verticalangle ironbracebetween the doorpanelsupport andthe doorbracket:

• Drill 3/16" fastening holes. Secure the door bracketusing the two self threading screws. (Figure 2)

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

Metal,insulated orlight weightfactory reinforceddoors:

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

Invisible Light Beam Protection Area

Safety Reversing Sensor 6" (15 cm) max. above floor

Introduction

Be sure power is NOTconnectedto the garage door opener BEFORE installing the safety reversing sensor. To prevent SERIOUS INJURY or DEATHfrom closing garage door:

• Correctlyconnectand align the safety reversing sensor. This required safety device MUSTNOT be disabled.

• Installthe safetyreversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor.

IMPORTANTINFORMATIONABOUTTHESAFETYREVERSINGSENSORS Thesafety reversing sensors must beconnected andalignedcorrectlybeforethe garagedoor openerwillmoveinthe downdirection.

The sending sensor (with an amber LED)transmits an invisible light beam to thereceiving sensor (with a green LED). Ifan obstruction breaks the light beam while the door is closing, the door will stop and reverse to the full open position,and thegarage door opener lightswill flash 10 times.

NOTE: For energyefficiency 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 issequenced 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 LEDswill light. The garage door opener will not go into the sleep mode until the garage door opener has completed 5 cycles upon power up.

Wheninstalling the safety reversingsensors check the following:

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

• Sensorsare facing eachother with the lensesaligned and thereceiving sensor lensdoes not receive directsunlight.

• Sensorsare no more than 6 inches (15 cm) above thefloor and the lightbeam is unobstructed.

PRE-WIRED INSTALLATIONS: If your garage

already haswiresinstalled for the safety reversing sensors,seepage 20.

OPTION A

INSTALLATION WITHOUT PRE-WIRING

2.1A Run thewire from both sensors to the

garage door opener. Attach the wire to the wall and ceiling withthe staples.

2.2A Strip 7/16 inch (11 mm) of insulation

fromeach set of wires. Separate the wires.Twistthe white wires together. Twist the white/blackwires together.

2.3A Insert the white wires intothe white terminal on

the garage door opener. Insert the white/black wires into the grey terminal on the garage door opener. To insertor remove thewires from the terminal,push in the tab with a screwdrivertip.

2.4B At the garage door opener, strip 7/16 inch(11 mm) ofinsulation from each end of the wirespreviouslychosen for the

safety reversing sensors. Twistthe like-colored wires together.

2.3B Connectthe pre-installed wires to thesensor wires with wire nuts

making sure the colors correspond foreach sensor. For example, the white wire would connect to the yellowwire and the white/black wire would connecttothe purple wire.

1 Connect Power

To avoid installation difficulties, do not activate thegarage door opener at this time.

To reduce the risk of electric shock, your garage door opener has a grounding type plug witha third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn’t fit intoyour outlet,contacta qualified electricianto install the proper outlet.

To prevent possible SERIOUS INJURY or DEATH from electrocution or fire:

• Be sure power is NOT connectedtotheopener, anddisconnectpower to circuit BEFORE removing cover toestablish permanent wiring connection.

• Garage door installationandwiringMUST be in compliancewith ALL local electrical andbuilding codes.

• NEVER use an extension cord, 2-wire adapter, or changeplugin any way to make it fit outlet.Be sure the opener is grounded.

THEREARETWO OPTIONS FOR CONNECTINGPOWER:

OPTION A

TYPICAL WIRING

1.1A Plugin the garagedoor opener intoa grounded outlet.

1.2A DO NOT run garage door opener at this time.

OPTION B

If permanent wiring is required by your local code, refer to the following procedure. To makea permanent connection through the7/8inch hole in the top of the motor unit (according to local code):

Wiringthrough a filter board(8550 models manufactured beforeApril12, 2013):

PERMANENT WIRING

1.1B Besure power is NOT connected to the opener, and disconnect power to circuit.

1.2B Remove the garage door opener cover andset aside.

1.3B Remove the attachedgreengroundterminal.

1.4B Cut black and whitewires. Strip away 1/2 inch (1 cm) of insulation, 3 inches (7.5 cm) before spade terminals.

1.5B Remove the power cord fromopener.

1.6B Install a conduit or flex cable adapter tothe7/8inch hole.

1.7B Run wires throughconduit, cuttoproper length andstrip insulation.

1.8B Attach with wire nuts provided. Attach the groundwireto the green groundscrew. The opener must be

grounded.

1.9B Properly secure wire under plastic ties sothatwire does notcomein contact with moving parts.

1.10B Reinstall the cover. DO NOT run garage door opener at this time.

Wiringthrough a terminal block (8550 modelsmanufacturedafter April 12, 2013 and all8557 models):

1.1B Remove the motor unit cover screws and set the cover aside.

1.2B Remove the attached3-prong cord.

1.3B Connect the black (line) wire to the screw on the brass terminal; the white (neutral) wire to the screw on the silver

terminal; and the groundwire to the green groundscrew. The opener must be grounded.

1.4B Reinstall the cover.

INTRODUCTION

Your garage door opener is designed with electronic controlsto make setup and adjustmentseasy. The adjustmentsallow you to programwhere the door will stop in the open (UP) and close(DOWN) position. The electronic controlssense the amountofforce required to open and closethe door. The force is adjusted automatically when you program thetravel.

NOTE: Ifanything interferes with the door’s upward travel it will stop. Ifanything interferes with the door’sdownward travel, it will reverse.

2 Test the Safety Reversal System

Withouta properly installed safetyreversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• Safetyreversal system MUST be tested every month.

• After ANY adjustments are made,the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.8cm)high object (or 2x4 laid flat)on the floor.

3 Test the Protector System

Withouta properly installed safetyreversing sensor,persons (particularly small children) could be SERIOUSLY INJUREDor KILLED by a closing garage door.

2.1 With the door fully open, placea 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 thepath of the door.

2.2 Press the remote control push button to

close the door.The door MUSTreverse when it makes contactwiththe 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 lightswill flash 10 times.

Ifthedoor stops and does notreverseon the obstruction,increase the downtravel (refer to Adjustment Step 1).

Repeat the test.When the door reverses upon contact with the 1-1/2inch board, remove the board and open/close the door 3 or 4 times to testthe adjustment.

Ifthegarage door opener continuesto fail the safetyreversaltest, call a trained door systemstechnician.

The garage door opener will not close froma remote control ifthe LED in either safety reversing sensoris off(alerting you to the fact thatthe sensor is misaligned or obstructed).

Ifthegarage door opener closesthe door when the safety reversing sensor is obstructed (and the sensorsare no more than 6 inches [15 cm]above the floor),call for a trained doorsystemstechnician.
