This microwave oven requires a mounting space on a wall as shown in Figure 1.
The unit should be attached to a minimum of one 2" x 4" wall stud.
For proper installation and servicing, a 2-inch space is necessary between the top of the range
To find the location of the studs, one of the following methods may be used:
backsplash and the bottom of the Over the Range Microwave Oven.
A. Use a stud finder, a magnetic device which locates the nails in the stud.
B. Use a hammer to tap lightly across the mounting surface to find a solid sound. This will
indicate stud location.

Note: In the event that the unit will be unable to be supported by any stud, it will be necessary
to use special care in the placement of the toggle bolts and top cabinet screws. See Wall
