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 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.
• Installation Step 12 – Depending upon garage construction,
extension brackets or wood blocks may be needed to install
sensors.
• Installation Step 12 – Alternate floor mounting of the safety
reversing sensor will require hardware not provided.
• Do you have an access door in addition to the garage door?
If not, an emergency key release is required.
• Look at the garage door where it meets the floor. Any gap
between the floor and the bottom of the door must not
exceed 1/4" (6 mm). Otherwise, the safety reversal system
may not work properly. See Adjustment Step 2. Floor or door
should be repaired.
