LOCATION REQUIREMENTS
• Any built-in dishwasher must be fully enclosed on the top, sides, and back and must not support any part of the
enclosure. Therefore, the cabinet space below your countertop is the best location.
• The cabinet opening must be at least 23'' (58.4 cm) deep and 23.6'' (60 cm) wide and 32.5''-34.5'' (82.5 cm – 87.5
cm) high as shown in Figure A.
• If the dishwasher is to be installed in a corner, make sure there is an adequate clearance to open the door. A
minimum of 2” (5 cm) is required between the dishwasher and an adjacent wall, as shown in Figure B.
• Select a location as close to the sink as possible for easy connections to water and drain lines.
• To ensure proper drainage, the dishwasher should not be installed more than 10 feet (3 meters) from the sink.
• Do not install dishwasher over carpeted flooring.

WATER SUPPLY REQUIREMENTS
Installing the water supply line
NOTE: The water supply hose is located inside the tub.
1. Turn off the water supply.
2. Install a hand shut-off valve in an accessible location,
such as under the sink. (Optional, but strongly recommend-
ed, and may be required by local codes.)
3. As shown in Figure F, connect one end of the inlet line
(A) to the 3/4-inch FHT (B) and connect to the dishwasher.
4. Run the other end of the inlet line through the hole in the
cabinet. If the shut-off valve is 3/8 inch I.D, the inlet line can
be directly connected to the shut-off valve.
5. Adjust the water heater so that it delivers water
temperature between 120°F (49°C) and 150°F (65°C).
6. Flush the water line to clean out debris.
Important! Make sure there are no sharp bends or kinks in
the water line, which might restrict water flow.
