Things to consider if you are planning to "Do-it-yourself."
This opener is designed for use with SECTIONAL doors only.
In many cases you will be replacing an existing door opener with a new one,however,if this will be the first opener
installed there are some pre-installation issues which need to be addressed. They are as follows:
The 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 Corporation or an authorized Overhead Door Dealer.
(The issue numbers below refer to the circled numbers in the illustrations on page 5.)
PRE-INSTALLATION CHECK LIST ............................................. FOR HELP-1.800.929.3667 OR WWW.OVERHEADDOOR.COM
1
Check 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 position needed with
respect to the garage door opener.It may be necessary
to add an additional bracket and fasteners (not included
with your new door opener kit). (Refer to Section 2)
2
Check the wall directly above the garage
door. The door opener’s header bracket must be
securely fastened to this wall.Insure that the structure
will provide a strong mounting location.
(Refer to Section 2)
3
Check to see if the mounting location for the
Safe-T-Beam® System is clear from obstruction
and has a wood surface available for attaching the
mounting brackets. The brackets may be attached
to concrete if necessary but extra tools and special
fasteners (not supplied) will be required.
(Refer to Section 4 and 5)
NOTE: Mounting brackets must be installed within
code specifications.
4
Is your sectional garage door made of
aluminum, light-weight steel,fiberglass or
glass panels? Additional support bracing must be
added to these type doors. If this is the case, please
contact the door manufacturer or authorized dealer so
that they can furnish you with a "bracing kit."
(Refer to Section 2)
WARNING
TO REDUCE THE RISK OF INJURY TO PERSONS OR
DAMAGE TO PROPERTY - USE THIS OPENER ONLY
WITH SECTIONAL DOORS.
