Before you start
- Improper lifting can cause severe personal injury. Have sufficient manpower for lifting and mounting the cabinet.
Procedure
- Check the location to be sure that no wires or plumbing, gas, or exhaust lines run behind the wall.
- Install two mounting bolts in the wall for the cabinet mounting keyholes.
- With the shipping box standing so the cabinet is upright, carefully remove the top and sides of the box.
- Raise the cabinet and mount it on the two mounting bolts in the wall.
- Install the two remaining mounting bolts, but do not tighten them.
- Push the cabinet against the wall. If the cabinet does not align flush against the wall, shim the mounting bosses as required.
- Tighten all mounting bolts.
