Before you begin, survey your garage area to see whether any of the conditions below apply to your installation.

Based on your particular requirements, there are
several installation steps which might call for
materials and/or hardware not included in the carton.

• Step 1, page 12 - Look at the wall or ceiling above

the garage door. The header bracket

must be

securely fastened to structural supports.

• Step 5, page 17 - Do you have a finished ceiling in

your garage? If so, a support bracket and
additional fastening hardware may be required.

• Safety reversing sensor, page 21 - Depending

upon garage construction, wood blocks may need
to be fastened to mounting locations before
sensors are installed.

• Step 10, page 22 - Alternate floor mounting of the

safety reversing sensor will require hardware not
provided.

• Step 11, page 24 - Do you have a steel, aluminum,

fiberglass or glass panel door? If so, horizontal
and vertical reinforcement is required.

• Look at the garage door where it meets the

floor. It must close on the floor all the way
across. Otherwise, the safety reverse system
may not work properly. See page 30. Floor or
door should be repaired.

SECTIONAL Door Installation

• If your door is more than 7 feet high, see the rail

extension kits available on page 38.

• The opener can be installed within 2 feet to the left

or right of the door center if there is a torsion spring
or center bearing plate in the way of the header
bracket or door bracket area.

If your door has

extension springs, the opener must be installed
in the center of the door. See pages 12 and 24.

• Do you have an access door in addition to the

garage door? If not, Model 18752 Outside
Trolley Release is required. See page 38.

You may find it
helpful to refer

as you proceed
with the installation
of your opener.
