There are 2 options for securing the dishwasher. For countertops made of wood or other materials that won’t be damaged by drilling, use method 1.
For countertops made of granite, marble, or other materials that could be damaged by drilling, use method 2.
For a flush installation, choose the appropriate method considering your installation conditions. (A flush installation may not be possible because of the cabinet size or installation circumstances.)
Method 1: Securing to Countertop
Insert the tabbed end of the installation brackets into the slots in the upper frame. Rotate the brackets until the tabbed ends are facing up.Bend the tabs on the brackets to secure them to the frame using a pair of needle nose pliers.
Method 2: Securing to Cabinets
For countertops made of granite, marble, or other materials that could be damaged by drilling, secure the dishwasher to the cabinets. If you have framed cabinets, use screws that are long enough to secure the dishwasher to the cabinets or attach wood spacers (not included) to the cabinets on either side of the dishwasher. See Securing Dishwasher in Cabinet Opening for more details.
