2. Drill the mounting holes:

   1. Drill 3/8″ (9.5 mm) diameter holes 3-1/4″ (83 mm) deep.

   2. Remove debris from the holes.

1. Slide the mount housing bracket from the kit into the subbase.

2. Use a Phillips head screwdriver and the eight screws from the kit to attach the mount housing bracket to the subbase rails.

1. Use a 5/32″ hex key to loosen the six adjustment screws on the inside of the mount housing bracket.

2. Slide the mount into the housing and align the holes in the mount with the holes in the housing plate.

3. Lower the housing plate so that it sits snugly on top of the mount.

Some older Preference Collection cabinets may need new mounting holes drilled in the bottom panel for the four decorative screws that secure the upper support bracket assemblies. If necessary, drill these additional holes before beginning the installation. Holes should be 3/8″ (9 mm) in diameter and 2″ (51 mm) from the side and bottom edges of the panel. The diagram in the “Parts Identification” section shows the newer-style bottom panel.

1. Use a 3/16″ hex key to loosen the six (1/4-20 x 1/2″ socket head patch) adjustment bracket screws. This allows the adjustment brackets to slide up as needed when the mount is inserted under the cabinet.

2. Slide the mount under the cabinet.

3. Partially tighten the six adjustment bracket screws.

4. Position the anchor plate on the two adjustment brackets.

5. Use a 3/16″ hex key and the four socket head patch screws and washers included in the kit to secure the anchor plate. Partially tighten the screws so the mount moves freely while positioning and to help ensure good contact with the floor.

6. Check that the mount is flush with the floor.

7. Use a 5/16″ hex key to tighten the mount screws until snug.

8. Verify that the mount did not lift up when the anchor plate was installed. The mount should still be flush with the floor.

9. Use a 3/16″ hex key to fully tighten the six adjustment bracket screws.
