INTRODUCTION

Safety Symbol and Signal Word Review

This garage door opener has been designed and tested to offer safe service provided it is installed, operated, maintained and tested in strict accordance with the instructions and warnings contained in this manual.

WARNING

CAUTION

To prevent damage to garage door and opener:

• ALWAYS disable locks before installing and operating the opener.

• ONLY operate garage door opener at 120V, 60 Hz to avoid malfunction and damage.

To prevent possible SERIOUS INJURY OR DEATH:

• ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door may not reverse when required.

• NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their hardware, all of which are under EXTREME tension.

• Disable ALL locks and remove ALL ropes connected to garage door BEFORE installing and operating garage door opener to avoid entanglement.

Preparing your garage door

Before you begin:

• Disable locks.

• Remove any ropes connected to garage door.

• Complete the following test to make sure your garage door is balanced and is not sticking or binding:

1. Lift the door about halfway as shown. Release

the door. If balanced, it should stay in place, supported entirely by its springs.

2. Raise and lower the door to see if there is any

binding or sticking.

If your door binds, sticks, or is out of balance, call a trained door systems technician.

SECTIONAL DOOR INSTALLATION

Planning

Identify the type and height of your garage door. Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page and the accompanying illustrations as you proceed with the installation of your opener.

Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.

• Installation Step 1 – Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural supports.

• Installation Step 5 – Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware may be required.

• Installation Step 10 – Depending upon garage construction, extension brackets or wood blocks may be needed to install sensors.

• Installation Step 10 – Alternate floor mounting of the safety reversing sensor will require hardware not provided.

• Do you have an access door in addition to the garage door? If not, Model 7702CB Outside Quick Release is required. See Accessories page.

• Look at the garage door where it meets the floor. Any gap between the floor and the bottom of the door must not exceed 1/4". Otherwise, the safety reversal system may not work properly. See Adjustment Step 3. Floor or door should be repaired.

SECTIONAL DOOR INSTALLATIONS

• Do you have a steel, aluminum, fiberglass or glass panel door? If so, horizontal and vertical reinforcement is required (Installation Step 11).

• The opener should be installed above the center of the door. If there is a torsion spring or center bearing plate in the way of the header bracket, it may be installed within 4 feet to the left or right of the door center. See Installation Steps 1 and 11.

• If your door is more than 7 feet high, see rail extension kits listed on Accessories page.

Horizontal and vertical reinforcement is needed for lightweight garage doors (fiberglass, steel, aluminum, door with glass panels, etc.). See page 24 for details.

ASSEMBLY STEP 1

Assemble the T-Rail and Attach the Cable Pulley Bracket

To avoid installation difficulties, do not run the garage door opener until instructed to do so.

1. Align the four T-rail sections on a flat surface

exactly as shown. Center sections are interchangeable. Front and back sections are also interchangeable for ease of assembly.

2. Insert the carriage bolts so the square bolt necks seat in the square holes in the T-rail sections and pass through the round holes in the rail braces.

Make sure bolt necks are seated in the square holes and rails are aligned before you tighten lock nuts. Improper assembly can cause

jerky trolley operation, noise and/or nuisance door reversals.

3. Assemble lock nuts, ensure alignment and tighten.

NOTE: If T-rail is not assembled exactly as shown, trolley will not travel smoothly along length of rail or it will hit against nuts.

4. Position the cable pulley bracket on the front end of the T-rail as shown. Fasten securely with the hardware shown.

NOTE: When tightening the screws, be sure to keep bracket parallel to the rail. Otherwise, the rail

may bow when the opener is operated.

INSTALLATION STEP 1

Determine the Header Bracket Location

Installation procedures vary according to garage door types. Follow the instructions which apply to your door.

SECTIONAL DOOR AND ONE-PIECE DOOR WITH TRACK

1. Close the door and mark the inside vertical centerline of the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet of the left or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling (see page 14) when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2".)

If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports as shown here and on page 13.

3. Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2" above the high point. This height will provide travel clearance for the top edge of the door.

Proceed to Step 2, page 14.
