To avoid damage to your door and/or
operator, make sure you disable any door
locks prior to installing your operator
.
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
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).
2
Check 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.
3
Check 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.”
7
Insure 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, y
ou 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.
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.
