Planning
Identify the type and height of your garage door.
Survey your garage area to see if any of the
conditions below apply to your installation. Additional
materials may be required. You may find it helpful to
refer back to this page and the accompanying
illustrations as you proceed with the installation of
your opener.
Depending on your requirements, there are several
installation steps which may call for materials and/or
hardware not included in the carton.
• Installation Step 1 – Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
• Installation Step 5 – Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
B&D recommends the use of safety infra-red
beam sensors on all installations of automatic
garage door openers.
• Installation Step 10:
– Depending upon garage construction, extension
brackets or wood blocks may be needed to
install the safety infra-red beam sensors.
– Alternate floor mounting of the safety infra-red
beam sensors will require hardware not provided.
• Do you have an access door in addition to the
garage door? If not, Model T7012 Emergency
Access Device is required.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforce-
ment is required (Installation Step 11).
• The opener is normally installed at the center of
the door. If there is a torsion spring or center
bearing plate in the way of the header bracket or
door bracket area, the opener may be installed
within 300mm to the left or right of the door center.
See Installation Steps 1 and 11.
• 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 Adjustment Step 3. Floor or door
should be repaired.
