3. IMPORTANT SAFETY INFORMATION

2. ADVANCED FEATURES

1. INTRODUCTION

WARNING means that severe injury or death could

result from failure to follow instructions.

CAUTION means that property damage or injury

could result from failure to follow instructions.

Operate the garage door opener at 120V, 60MHz to avoid opener damage.

Garage doors are heavy, moving objects. When coupled with an automatic opener, electrical power is also

present. If not properly installed, balanced, operated, and maintained, an automatic door can become

dangerous and cause serious injury or death. Please pay close attention to the WARNING and CAUTION

notices that appear throughout this manual. Failure to follow certain instructions may result in damage to

the door or door opener, or may result in severe injury or death to yourself or others.

The instructions will refer to the tools shown below for proper installation, adjustment, and maintenance of the garage door opener. Additional tools may be required depending on your particular installation.

4. TOOLS

Fig. 1

Take a moment to survey your garage and garage door.

■ Is there an access door besides the garage door? If not, you should install an emergency key release kit.

■ With the garage door closed, check alignment of door and garage floor. The gap, if any, should be no more than 1/4". If the gap is larger than this, repair floor or door before installing opener.

■ The opener is intended for installation on a properly balanced and adjusted garage door. DO NOT INSTALL IF DOOR IS UNBALANCED OR BROKEN.

■ Check balance of door in mid travel and during full range of opening and closing. Lift the door about half way, as shown in Fig. 2 & 3. Release the door. It should remain in place, supported by its springs. Raise and lower the door fully to check for binding or sticking.

■ If door is out of balance or needs repair, DO NOT ADJUST IT YOURSELF. CALL A QUALIFIED GARAGE DOOR SERVICE PROFESSIONAL to adjust your door.

■ If your door is over 7 ft. high, you will need a longer rail. See section “6. Rail Assembly" on p. 6 of this manual for availability of longer rails.

5. GARAGE

A garage door is a heavy moving object and can

cause serious injury or death. An unbalanced door

might not reverse when required, and can increase

the risk of injury. If your garage door is out of

balance, or if it binds or sticks, call for professional

garage door service. Garage doors, springs,

pulleys, cables, and hardware are under extreme

tension and can cause serious injury or death. Do not try to adjust them yourself. Ropes left

on a garage door could cause someone to become

entangled and could kill them. Remove all ropes

connected to the door before installing your opener.

To prevent damage to steel, aluminum, fiberglass or

glass panel doors, always reinforce the inside of the

door both vertically and horizontally with steel or

angle iron bracing.

The best solution is to follow the instructions for your particular garage door or contact the garage door manufacturer for proper reinforcement instructions.

7. IMPORTANT INSTALLATION INSTRUCTIONS

IMPORTANT INSTALLATION INSTRUCTIONS

TO REDUCE THE RISK OF SEVERE INJURY OR DEATH:

1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.

2. Check with the door manufacturer to determine if additional reinforcement is required to support the door prior to installation of the garage door opener.

3. Install garage door opener only on a properly balanced garage door. An improperly balanced door could cause serious injury. Have a qualified service person make repairs to garage door cables, spring assemblies, and other hardware before installing the opener.

4. Remove all ropes and remove or make inoperative all locks connected to the garage door before installing opener.

5. If possible, install the door opener 7 feet or more above the floor. Adjust the emergency release cord so that knob hangs 6 feet above the floor.

6. Do not connect the opener to source of power until this manual instructs you to do so.

7. Locate the wall control panel or wall button: (a) within sight of door, (b) at a minimum height of 5 feet above the ground so small children cannot reach it, and (c) away from all moving parts of the door.

8. Place the Operating Warning Label next to the wall control panel or wall button in a prominent location. Affix Safety Label on inside of garage door. The Emergency Release Tag must remain on the emergency release cord.

9. After installing the opener, test Safety Reversal System. Door MUST

reverse when it contacts a 1-1/2 inch high

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

For Important Safety Instructions see page 21.

Shown on the right is an overall view of a completed garage door opener system installed on a sectional door. The arrangement is similar for a one-piece door (except for differences described later in this manual).

Identify a sound structural support on header wall above garage door for header bracket mounting. See Fig. 11. If appropriate header does not exist, replace or install a new support using a 2x4 or 2x6 board. Fasten it securely using lag screws (not provided) to structural supports of garage.

Before starting your installation, the door and the header above the door must be measured and marked. This way, the appropriate brackets can be mounted at the correct locations avoiding installation and operating difficulties later.

MARK VERTICAL CENTER LINE:

■ Measure door width, then locate the center point (Fig.10).

■ Mark a vertical line on the upper half of your door, on the

top edge of your door, and on the header, through the center point.

MEASURE DOOR’S HIGHEST TRAVEL POINT:

(Review Figs. on p. 5 for details)

■ Open door to its highest travel point and measure from the garage floor to the top of door.

■ Write down this distance.

FOR SECTIONAL DOORS AND ONE-PIECE DOORS WITH HORIZONTAL TRACK:

Add 1-1/4" to the door travel height (measured above).

FOR ONE-PIECE DOORS WITHOUT TRACK:

Add 3-3/4" to the door travel height (measured above).

MARK HORIZONTAL LINE FOR HEADER BRACKET LOCATION:

■ Close door and measure the required distance (determined above) from the garage floor to the header.

■ Mark a horizontal line, intersecting the vertical center line, on header. This is the position at which the bottom of the header bracket should be installed.

■ In case of minimal clearance above the door, the header bracket may be mounted to the ceiling. In this case, extend the vertical center line onto the ceiling, and mark a horizontal line on the ceiling no further than 4" from the header wall. The header bracket should be mounted no farther than this distance from the header wall.

8-2. INSTALL HEADER BRACKET

8-1. MEASURE AND MARK DOOR AREA

8. INSTALLATION STEPS

If the header bracket is not rigidly fastened to a sound

structural support on the header wall or ceiling, the

safety reverse system may not work and could cause

serious injury or death. DO NOT move or adjust springs

or garage door hardware, as these parts are under

extreme tension and could cause injury or death.

■ Mark pilot holes location on header through holes where lag screws will be inserted. IMPORTANT: See Fig. 11 for which header bracket holes to use.

■ Drill 3/16" pilot holes into header, and install bracket with lag screws (5/16 x 1-5/8”) provided.

■ Tighten lag screws firmly.

NOTE: Follow the same procedure if header (shown in Fig.

11) runs vertically instead of horizontally and is the only

option for mounting header bracket to header wall. In case of minimal clearance above the garage door, the header bracket may be mounted to the ceiling. Follow the same steps above to ensure a sound surface for mounting.

A. FOR SECTIONAL DOORS:

Wood Sectional Doors (Fig. 14)

■ Position door bracket (Fig. 13) along vertical center line of door with pin hole facing top of the door and top edge of the bracket 4” to 5” below top edge of the door, or roughly at the same height as top rollers on the door.

■ Mark locations of securement holes through door bracket.

■ Drill two 1/4" holes through door for securement of

door bracket.

■ Insert carriage bolts (1/4” x 2”) from the outside through door and bracket, then secure with lock washers and nuts from the inside.

■ Tighten nuts firmly.

Metal Sectional Doors

■ Attach door bracket with two teck screws (provided) per door manufacturer recommendations.

B. FOR ONE-PIECE DOORS:

Before starting the installation of the door bracket, cut off mounting leg from opposite side of pin hole.

One-Piece Doors with Exposed Frames (Fig. 15)

■ Position center of door bracket on the center line on the top edge of door.

■ Mark the position where carriage bolts will go through bracket, and drill two 1/4" holes through top frame of door.

■ Install carriage bolts from the bottom, through door frame and bracket, and secure with lock washer and nut from top.

■ Tighten nuts firmly.

■ For sectional doors, proceed to step 8-5.

ADDITIONAL STEP FOR ONE-PIECE DOORS ONLY:

IMPORTANT NOTE: For installation on One-Piece Doors only, the straight door arm that is factory installed onto the rail must be replaced by the curved door arm supplied as part of hardware in powerhead box. This must be done after attaching rail to powerhead, before moving to step 8-5.

■ Turn rail and opener head over so that open channel in rail faces up.

■ Untape straight door arm that is secured inside rail.

■ Remove and save the two phillips head screws that are

securing the door arm pin and straight door arm (Fig. 18).

■ Lift arm and pin straight out of slot in trolley, and remove pin from straight door arm.

■ Insert pin into short side of curved door arm as shown.

■ Orient arm so that long side extends away from trolley.

■ Carefully insert pin and door arm into slot in trolley.

Push pin into slot with door arm so pin is fully seated into trolley slot. IMPORTANT: Pin must be straight and seated properly into recessed area in trolley. See Fig. 18A.

■ Secure pin and curved arm with the two phillips screws which were removed from trolley—DO NOT use any other screws. Tighten screws firmly.

■ Turn rail and powerhead over so that open channel in rail faces down. Now proceed to Step 8-5.

8-4. ATTACH RAIL TO OPENER HEAD

When fastening the rail to the opener, use only the screws provided. Use of any other screws may result in opener falling

from ceiling and causing damage

to persons or property in the garage.
