Drain Requirements:
A new drain hose is supplied with your dishwasher. If this is not long enough, use a new drain hose with a maximum length of 12' (3.7 m) (Part Number 3385556) that meets all current AHAM/IAPMO test standards, is resistant to heat and detergent, and fits the 1" (2.5 cm) drain connector of the dishwasher.
Make sure to connect the drain hose to waste tee or disposer inlet above drain trap in house plumbing and 20"(50.8 cm) minimum above the floor. It is recommended that the drain hose either be looped up and securely fastened to the underside of the counter, or be connected to an air gap. Make sure to use an air gap if the drain hose is connected to house plumbing lower than 20"(50.8 cm) above sub-floor or floor.
Use ¹⁄₂ " (1.3 cm) minimum I.D. drain line fittings. If required, the air gap should be installed in accordance with the air gap installation instructions. When you connect the air gap a rubber hose (not provided) will be needed to
connect to the waste tee or disposer inlet.
