SECTIONAL DOOR

To avoid damage to the garage door and opener, disable locks before installing and operating the opener. Use a wood screw or nail to hold locks in the "open" (unlocked) position.

Operation at other than 120V 60 Hz will cause opener malfunction and damage.

WARNING

CAUTION

WARNING

Identify the type and height of your door and any special conditions that exist and any additional materials that may be required by referring to the lists on page 4 or page 5.

Before you begin, complete the following test to make sure your door is balanced, and is not sticking or binding:

• Lift the door about halfway as shown. Release the door. It should stay in place, supported entirely by its springs.

• Raise and lower the door to see if there is any binding or sticking.

An unbalanced garage door might not reverse when required and someone under the door could be seriously injured or killed.

If your garage door binds, sticks or is out of balance, call for professional garage door service .

Garage doors, door springs, cables, pulleys, brackets and their hardware are under extreme tension and can cause serious injury or death.

Do not try to loosen, move or adjust

them yourself!

Ropes left on a garage door could cause someone to become entangled and killed.

Remove all ropes connected to the door before installing and operating the opener.

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

Assembly Step 1

Assemble the T-rail & Attach the Cable Pulley Bracket

When tightening the screws, be sure to keep bracket parallel to the rail. Otherwise, the rail may bow when the opener is operated.

Assembly Step 2

Install the Trolley on the T-rail

• Place the opener on packing material to protect the

cover. For convenience, put a support under the cable pulley bracket.

• Remove the (2) 5/16"-18x1/2" washered screws mounted in the top of the opener.

• Align the holes in the back section of the T-rail with the holes in the opener.

• Fasten the rail with the (2) washered screws previously removed. Tighten securely.

Remember to use only these screws!

Any other

screws will cause serious damage to the opener.

• Insert a 5/16"-18x7/8" hex screw into the cover protection bolt hole in the T-rail as shown. Tighten securely with a 5/16" lock washer and nut.

NOTE: This screw prevents trolley over-travel. Keep a 2" minimum between the trolley and this screw when adjusting travel limits (see page 28).

IMPORTANT INSTALLATION INSTRUCTIONS

To reduce the risk of severe injury or death to persons:

1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS

2. Install only on a properly balanced and lubricated garage door.

An improperly balanced door

may not reverse and could result in severe injury or death.

Repairs to cables, spring assemblies

and other hardware must be made by a professional service person before installing opener.

3. Disable all locks and remove all ropes connected to the garage door before installing the opener.

Ropes connected to a garage door can cause entanglement and death.

4. If possible, install door opener 7 feet or more above floor with the manual release handle mounted 6 feet above the floor.

5. Do not connect the opener to power source until instructed to do so.

6. Locate the Door Control within sight of the door at a minimum height of 5 feet where small children cannot reach and away from all moving parts of the door.

7. Install the User Safety Instruction Label on the wall adjacent to the control button and the Maintenance Instruction Label in a prominent location on the inside of the garage door.

8. Upon completion of the installation, the door must reverse when it comes in contact with a oneinch high object (or a 2x4 laid flat) on the floor.

9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or loose clothing can be caught in the mechanism of the garage door or the opener.

You have now finished assembling your garage door opener. Please read the following warnings before proceeding to the installation section:

WARNING

Tighten the Chain & Cable

• Spin the inner nut and lock washer down the threaded shaft, away from the trolley.

• To tighten the chain, turn outer nut in the direction shown. As you turn the nut, keep the chain

from twisting.

• When the chain is approximately 1/2" above the base of the T-rail at its midpoint, re-tighten the inner nut to secure the adjustment.

Sprocket noise can result if chain is either too loose or too tight.

When installation is complete, you may notice some chain droop with the door closed. This is normal. If the chain returns to the position shown when the door is open,

do not re-adjust the chain.

NOTE: During future maintenance, pull the manual release handle to disconnect trolley before adjusting chain.

Installation Step 1

Determine Header Bracket Location

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

If the header bracket is not rigidly fastened to a structural support on the header wall or ceiling, the safety reverse system may not work properly (see page 30).

The door might not reverse when required, and could cause serious injury or death.

The garage door springs, cables, pulleys, brackets and their hardware are under extreme tension.

Do not attempt to loosen, move or adjust them yourself. Serious personal injury or death could result.

Call for professional

garage door service.

WARNING

a torsion spring or center bearing

only

plate is in the way; or you can attach it to the ceiling (refer to 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 supplied) to securely fasten the 2x4 to structural supports as shown here and on page 13.

• 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.
