The safety reversing sensors must be connected and aligned correctly before

the garage door will move in the down direction. This is a required safety device

and cannot be disabled.

1. Install and align the brackets so the safety reversing sensors will face each

other across the garage door, with the beam no higher than 6" (15 cm) above

the floor.

2. Wire to the garage door opener, see

WIRING AND POWER (D)

Inspect the torsion bar while raising and lowering

the door; there should be no noticeable shifting

or vibrating of the door. If the movement is not

corrected, the life of the garage door opener will

be greatly reduced.

Lift the door halfway up.

Release the door. If balanced, it

should stay in place, supported

entirely by its springs. Doors

heavier than 650 lbs. should

NOT open or fall rapidly.

Test the Safety Reversal System

1. With the door fully open, place a 1-1/2" (3.8 cm) board (or a 2x4 laid

flat) on the floor, centered under the garage door.

2. Press the remote control push button to close the door. The door

MUST reverse when it makes contact with the board.

If the door stops but does not reverse:

1. Review the installation instructions provided to insure all steps were

followed;

2. Repeat Program the Travel (see Adjustment Step 1);

3. Repeat the Safety Reversal test. If the test continues to fail, call a

trained door systems technician.

Program the Travel

1. Press and hold the Adjustment Button until the UP Button begins to

flash and/or a beep is heard.

2. Press and hold the UP Button until the door is in the desired UP

position.

3. Once the door is in the desired UP position, press and release the

Adjustment Button.The garage door opener lights will flash twice and

the DOWN Button will begin to flash.

4. Press and hold the DOWN Button, until the door is in the desired DOWN

position.

5. Once the door is in the desired DOWN position, press and release the

Adjustment Button. The garage door opener lights will flash twice and

the UP Button will begin to flash.

6. Press and release the UP Button. When the door travels to the

programmed UP position, the DOWN Button will begin to flash.

7. Press and release the DOWN Button. The door will travel to the

programmed DOWN position. Programming is complete.

Test the Protector System

®

1. Press the remote control push button to open the door.

2. Place the opener carton in the path of the door.

3. Press the remote control push button to close the door.

The door will not move more than 1" (2.5 cm), and the

opener lights will flash.

The garage door opener will not close from a remote if the

indicator light in either sensor is off (alerting you to the fact

that the sensor is misaligned or obstructed).

Test Cable Tension Monitor

With the door fully closed, push on the front of the cable tension

monitor. A click should be heard. If there is no click, the roller may be

hitting the jamb and not allowing the switch to detect slack in the

cable. Make sure the cable tension monitor is mounted flush with the

wall and the roller is free from any obstructions.

If your cable tension monitor has been activated the UP and DOWN

arrows will flash diagnostic code 3-5.

Test the Automatic Garage Door Lock

1. With the garage door fully closed, the automatic garage door lock bolt

should be protruding through the track.

2. Open the garage door. The automatic garage door lock should retract

before the garage door begins to move.

3. Close the garage door. When the garage door reaches the fully closed

position, the automatic garage door lock should automatically activate to

secure the door.

Disengage the automatic garage door lock by sliding the manual release to

the open position.

To Open the Door Manually

Disengage any door locks before proceeding. The door should be fully

closed if possible. Pull down on the emergency release handle until a

click is heard from the garage door opener and lift the door manually.

To reconnect the door to the garage door opener, pull the emergency

release handle straight down a second time until a click is heard from

the garage door opener. The door will reconnect on the next UP or

DOWN operation.

opener on the same side as

the collar.

Mount the Garage Door Opener

1. Close the garage door completely. Slide the garage door opener onto the torsion bar. Ensure

the collar does NOT touch the bearing. Use a level to align the garage door opener.

2. Make sure the mounting bracket is located on a solid surface. If installing on drywall, the

mounting bracket MUST be attached to a stud. Mark and drill 3/16" pilot holes.

3. Tighten the collar set screws on the torsion bar. For a hollow torsion bar, tighten the screws

3/4 - 1 full turn after making contact with the bar. For a solid shaft torsion bar, tighten the

screws 1/4 - no more than 1/2 turn after making contact with the shaft. If installing on a

keyed torsion bar, DO NOT tighten the screws into the keyway.

4. Secure the mounting bracket to the wall. Tighten the mounting bracket to the garage door

opener.

Attach the Emergency Release Rope and Handle

1. Thread one end of the rope through the hole in the top of the red handle so “NOTICE” reads right side up.

Secure with an overhand knot at least 1" (2.5 cm) from the end of the rope to prevent slipping.

2. Insert the other end of the rope through the loop in the emergency release cable and secure with an

overhand knot.

Install the Automatic Garage Door Lock

Mount the lock above one of the door rollers. The third roller from the bottom of the door is ideal for most

installations. Drill holes in the track according to the template provided. Wire to the garage door opener, see

WIRING AND POWER (A)

.

Install the Cable Tension Monitor (Required)

Make sure there are no obstructions that prevent the cable tension monitor from closing completely when slack is

detected. For right side installation, remove the snap-ring holding the roller in place and reassemble it on the

opposite side of the cable tension monitor. Wire to the garage door opener, see

WIRING AND POWER (B)

.

Install on the same side as

the garage door opener if

possible.

corresponding battery terminals.

Connect Power

To reduce the risk of electric shock, your garage door opener has a grounding

type plug with a third grounding pin. This plug will only fit into a grounding type

outlet. If the plug doesn’t fit into your outlet, contact a qualified electrician to

install the proper outlet.

1. Plug in the garage door opener into a grounded outlet.

2. Check to make sure the LEDs in both sensors are glowing steadily. The LEDs

in both sensors will glow steadily if they are aligned and wired correctly.

If permanent wiring is required by your local code, refer to the manual.
