Check that all surfaces have no protrusions

that would prohibit dishwasher installation.

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.

Helpful Tip: Routing the water line through the left side of cabinet

opening will make water connection easier.

Drill a V2"(1.3 cm) hole in the cabinet side or rear.

Measure overall length of copper tubing or flexible braided water

supply line. Attach to the hot water line using a connection

configuration that is in compliance with local codes and

ordinances. The water line to the dishwasher should have a

manual shutoff valve.

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.

Copper tubing only: Slide nut, then ferrule, about 1" (2.5 cm) onto

copper tubing.

NOTE: To avoid vibration during operation, route the water supply

line so that it does not touch the dishwasher base, frame or motor.

water supply line ...................................................

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 5/8"open

ended wrench or adjustable wrench.

NOTE: Do not use Teflon ®ttape with compression fittings.

IMPORTANT: Always use a new drain hose. Check local codes to

determine whether an air gap is required.

If needed, drill a 1V2"(3.8 cm) diameter hole in cabinet wall or side

of the opening closest to the sink.

Route drain hose as shown through hole in cabinet to the front

center of opening where drain connection will be made. Tape

drain hose to the floor in area shown. This will prohibit it from

moving when dishwasher is moved into cabinet opening.

NOTE: If the minimum cabinet opening height is less than

34" (86.4 cm), the rear wheels can be removed for additional

clearance. This will allow the dishwasher to fit into a 337/8'' (86 cm)

high cabinet opening, but the dishwasher will be more difficult to

move. (Measurements are approximate. Wheels and legs are

preset at the factory for 34W' [87.6 cm].)

Adjust wheels and legs

Turn both leveler legs to the same height. Put wheels in the

required position determined from "Dishwasher Height

Adjustment Chart."

Built-up floors: If the kitchen floor is higher than the cabinet

opening's floor - for example, the kitchen floor tile does not

extend into the cabinet opening - add shims as needed in the area

shown to bring the dishwasher up to 34" (86.4 cm) below the

countertop.

NOTE: Shims must be securely attached to floor to avoid

movement when the dishwasher is in use.
