PRE-INSTALLATION CHECK LIST FOR HELP-1.800.929.3667 OR OVERHEADDOOR.COM

Things to consider if you are planning to “do-it-yourself.”

In many cases you will be replacing an existing door operator with a new one, however, if this will be the first operator installed there are some pre-installation issues which need to be addressed. They are as follows:

2The Overhead Door Corporation recommends that you read and fully understand all information and instructions contained herein before choosing a “Do-it-yourself” installation. Any questions should be directed to Overhead Door Corp. or an authorized Overhead Door Dealer.

(The issue numbers below refer to the circled numbers in the illustrations on page 3.)

1Check your ceiling where the power head of your new unit will be mounted.

Plan how you will be mounting the power head. It is possible that ceiling joists may not be in the exact position needed with respect to the garage door operator. In any case, it may be necessary to add an additional bracket and fasteners (not included with your new door operator kit).

2Check the wall directly above the garage door. The door operator’s header bracket

must be securely fastened to this wall. Insure that the structure will provide a strong mounting location.

3Check to see if the mounting location for the Safe-T-Beam®System “STB” is

clear from obstruction and has a wood surface available for attaching the “STB” brackets. The brackets may also be attached to concrete if necessary but extra tools and special fasteners (not supplied) will be required.

NOTE: 1-1/2" “STB” bracket adapters are available through your local Overhead door Dealer.

4 Is your garage door made of light-weight steel, aluminum, fiberglass

or glass panels? Additional support bracing must be added to these type doors. If this is the case, please contact the door distributor or manufacturer so that they can furnish you with a “bracing kit.”

5 You need a 110-120 Volt power supply available. If you plan to plug the unit into a

standard electrical outlet, is one available? The outlet should be no more than about 3 feet from the power head once it is mounted. (The cord is 4 ft. in length.) SEE WARNING BELOW.

6To avoid damage to your door and/or operator, make sure you disable any door

locks prior to installing your operator.

7Insure that your door is properly balanced and moving freely. SEE WARNING BELOW.

8(NOT SHOWN) If your garage does not have a separate entry door, you might want to

consider an emergency release kit (GER-2) for installation on your garage door. See page A at the center of this manual.

WARNING

DO NOT USE EXTENSION CORD! Extension cords can cause dangerous overheating conditions.

DO NOT USE PORTABLE GENERATOR! This product is designed to operate on standard house current. Do not use alternate power supplies.

WARNING

If your door sticks, binds, or is out of balance, have it adjusted by a professional. Door springs, cables, pulleys, brackets and associated hardware are under extreme tension and can cause serious injury or death.
