3.1.1.
Remove plastic cover from CONCIERGE.
3.1.2.
With the wide edge of the motor mount plate flush to the top of the door and 3 inches from the edge
of the door, secure the mount plate with at least the 4 supplied wood screws or binding post screws
using extended drill bit. Any holes in the mount plate may be used but it is advised to use the holes in
the outermost rows to follow best practice technique. Screw into door surfaces that are flush to the
back side of the motor mount plate. It is important the screws achieve a solid mount.
3.2.
Mounting the Shoe
First, remove the shoe from the upper lever arm. With the center line of the shoe 1.75 inches above the top of
the narrow edge of the motor mount plate and 16 inches from the hinge side edge of the door, secure the
shoe to the wall with 2 supplied wood screws. If there is a molding on the wall it is ok to attach the shoe but
make sure the screws that hold the shoe are properly anchored. If needed, use longer screws than those
supplied to ensure proper anchoring. It is important the screws achieve a solid mount.
