The AT-DDC Wall Clock can be mounted directly to a wall, to a single 
gang outlet box, double hung from the wall or double hung from the 
ceiling. When deciding where the clock will be mounted, keep in mind 
that 115VAC power is required.

After deciding the location where the clock will be mounted, 
make two marks 12" apart and horizontal.

 2 1/4" away from the ceiling.
