A new drain hose is supplied with your dishwasher. If drain hose is not long enough, use a new drain hose with a maximum length of 12 ft (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 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 subfloor or

floor. Use 1/2"minimum I.D. drain line fittings. If required, the air gap should be installed in accordance with

the air gap installation instructions. When you are connecting the air gap, a rubber hose (not provided) will be needed to connect to the waste tee or disposer inlet.

Be sure that the electrical connection and wire size are adequate and in conformance with the National Electrical Code, ANSI/NFPA

70 - latest edition and all local codes and ordinances. A copy of the above code standards can be obtained from:

Hot Water line

Measure overall length of copper tubing or flexible braided water supply line. Attach to the hot water line using a connection

configuration that isin compliance with local codes and ordinances. The water line to the dishwasher should have a

manual shutoff valve.

JAdd 90 ° elbow fitting to the

water supply line

Slowly route water supply line through hole in cabinet. (If you are using copper tubing, it will bend and kink easily, so be gentle.) It should be far enough into the cabinet opening to connect it to the

dishwasher inlet on the front left side of the dishwasher.

Slowly turn water shutoff valve to "ON" position. Flush water into a shallow pan until clear to get rid of particles that could clog the

inlet valve. Turn shutoff valve to "OFF" position.

Connect the 3/8"compression fitting to the water supply line prior to installing the unit into the cabinet opening. Attach such that the 3/4"connection is facing upward as shown above.

Copper tubing only: Put the tubing into the 90° elbow fitting as far as it will go (the copper tubing bends and kinks easily). Slide the

nut and ferrule forward and start the nut onto the elbow threads. Flexible braided connection: Secure nut to elbow using 3/8"open

ended wrench or adjustable wrench. NOTE: Do not use Teflon ®ttape with compression fittings.
