Mechanical Electrical

WARNING

CAUTIONCAUTION

You'll Need Tools

During assembly , installation and adjustment of the opener, inst ructions will call for hand tools shown below.

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.

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.

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

Test your Door

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.

Assembly Step 2

Attach Chain to Sprocket and Install Sprocket Cover

• Position chain over the opener sprocket. If necessary, loosen the outer nut on the trolley to obtain more chain slack.

• Insert the second washered screw.

CAUTION: Use only the screw previously removed from opener!

• Tighten both screws securely through the T-rail into the opener as shown.

Install The Sprocket Cover:

• Insert the back tab in the opener slot. Squeeze the cover slightly and insert the front tab in the slot on the mounting plate.

• Remove the two washered screws mounted in top of opener.

• Position T-rail at a 45˚ angle to opener so one hole in T-rail and opener line up.

• Thread one of the washered screws part way in.

Use only these screws!

Use of any other screws

will cause serious damage to door opener.

• Align T-rail and styrofoam over opener sprocket. Cut tape from T-rail, chain and styrofoam.

• REMOVE STYROFOAM.

Serious injury can result if fingers become entangled in moving opener sprocket. Attach sprocket cover securely. Never operate opener while your hand is near the opener sprocket.

CAUTIONCAUTION

WARNING

• 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,

ALWAYS

pull the manual release handle to disconnect trolley before adjusting chain.

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 Door Control 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 one-inch 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

• 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 10.

SECTIONAL Doors and

ONE-PIECE Door With Track

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

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

Remember, you can fasten the header bracket within 4 feet to 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 (refer to page 10) 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 9.

Installation Section: Pages 8 – 23

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 26).

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.

Fasten the Header Bracket to the Wall

• Center the bracket on the vertical guideline with the bottom edge of the bracket on the horizontal line as shown (with the arrow pointing toward the ceiling).

• Mark either set of bracket holes (do not use the holes designated for ceiling mount). Drill 3/16" pilot holes and fasten the bracket securely to a structural support with the hardware provided.

• Extend the vertical guideline onto the ceiling as shown.

• Center the bracket on the vertical mark, no more than 6" from the wall. Make sure the arrow is pointing toward the wall. The bracket can be mounted flush against the ceiling when clearance is minimal.

• Mark holes designated for ceiling mount only. Drill 3/16" pilot holes and fasten bracket securely to a structural support with the hardware provided.
