Unattended Operation
The Timer-to-Close (TTC) feature, the Craftsman Garage Door app, and Smart Garage Door and Gate Monitor are examples of unattended
close and are to be used ONLY with sectional doors. Any device or feature that allows the door to close without being in the line of sight
of the door is considered unattended close. The Timer-to-Close (TTC) feature, the Smartphone Control, and any other Smart Control
devices are to be used ONLY with sectional doors.
Preparing your garage door
Before you begin:
1. Disable locks and remove any ropes connected to the
garage door.
2. Lift the door halfway up. Release the door. If balanced, it
should stay in place, supported entirely by its springs.
3. Raise and lower the door to check for binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.
4. Check the seal on the bottom of the door. 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.
5. The opener should be installed above the center of the
door. If there is a torsion spring or center bearing plate in
the way of the header bracket, it may be installed within
4 feet (1.2 m) to the left or right of the door center. See
page 12.
