Method 1

1. Insert the long top mounting clips into the slot.
2. Bend the brackets to secure them to the dishwasher tub.
3. Secure the dishwasher to the countertop through the holes in the brackets, using the screws provided.

Important: Drive the screws straight and flush. Protruding screw heads will scratch the top of the control panel and interfere with the door closing.

Method 2

1.  Remove the plastic tub caps from the inside of the dishwasher tub.

2. Drive a wood screw through the hole in the side of the dishwasher into the cabinet frame.
   Important: Drive the screws straight and flush. Protruding screw heads will scratch the side of the dishwasher. This method is for attaching the dishwasher to the sides of the cabinet, and it should be done when the countertop is made of granite or other breakable materials.

3. Reinsert the plastic tub caps.

Step 14: Connecting the drain hose

Important: Follow all local codes and ordinances.

1. Cut on the marked line as required for your installation. The drain hose’s molded end will fit 5/8” or 1″ diameter connections on the air gap, waste tee, or garbage disposal.

2. If a longer drain hose is required, you can add up to 42″ (1.1 m) of length, for a total of 10 ft. (3.01 m) to the factory installed hose. Use 5/8” or 7/8” inside diameter hose and a coupler to connect the two hose ends. Secure the connection with screw-type hose clamps.
   Important: For proper drain operation, the total drain hose length must not exceed 10 ft. (3.01 m).

3. Secure the drain hose to the air gap, waste tee, or garbage disposal with a screw-type clamp, using the appropriate method below. See Drain preparation on page 6, if you do not know which method to use.
   Method 1 – Air gap to a waste tee or garbage disposal.

Method 2 – High drain loop to a waste tee or garbage disposal

4. If connecting the drain line to a garbage disposal, make sure that the drain plug has been removed. Your dishwasher will not drain if the plug is left in place.
