Location Requirements

Grounded electrical supply required. Do not run drain lines, water lines or electrical wiring where they

can interfere with or contact dishwasher motor or legs. The location where the dishwasher will be installed must provide

clearance between motor and flooring. Motor should not touch the floor.

Do not install dishwasher over carpeted flooring. Shelter dishwasher and water lines leading to dishwasher against

freezing. Damage from freezing is not covered by the warranty. A side panel kit is available from your dealer for installing your

dishwasher at the end of your cabinetry. A moisture barrier accessory (Part Number 4396277) is available

from your dealer for installing underneath the countertop.

Check location where dishwasher will be installed. The location must provide:

• easy access to water, electricity and drain.

• convenient access for loading and unloading dishes.

Corner locations require a 2" (5.1 cm) minimum clearance

between the side of the dishwasher door and the wall or

cabinet.

• square opening for proper operation and appearance.

• cabinet front perpendicular to floor.

• level floor. (If floor at front of opening is not level with floor

at rear of opening, shims may be needed to level dishwasher.)

Helpful Tip: Be sure to accurately measure dimensions and ensure dishwasher is level if the floor in the dishwasher opening is

uneven (example: Flooring extends only partway into opening). NOTE: To avoid shifting during dishwasher operation, shims must

be securely attached to the floor. If dishwasher will be left unused for a period of time or in a

location where it may be subject to freezing, have it winterized by authorized service personnel.

Make sure pipes, wires and drain hose are within the shaded area shown in the "Product and Cabinet Opening Dimensions" section.

©rain Requirements

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 3885556) 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.

E)ectdca) Requirements

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:

National Fire Protection Association 1 Batterymarch Park

Quincy, MA 02169-7471

You must have:

• 120-volt, 60 Hz, AC-only, 15- or 20-amp, fused electrical supply.

• Copper wire only.

We recommend:

• A time-delay fuse or circuit breaker.

• A separate circuit.

If connecting dishwasher with a power supply cord:

Use UL Listed power supply cord kit (Part Number 4317824) marked for

use with dishwasher. Power supply cord must plug into a grounded

3 prong outlet, located in the cabinet next to the dishwasher opening. Outlet must meet all

local codes and ordinances.

If connecting dishwasher with direct wiring:

• Use flexible, armored or nonmetallic sheathed, copper wire with

grounding wire that meets the wiring requirements for your home

and local codes and ordinances.

• Use a UL Listed/CSA Approved strain relief.

box. Select UL Listed/CSA Approved twist-on wire connectors rated to

connect your power supply cord to 16-gauge dishwasher wiring.

Electrical Shock Hazard

Electrically ground dishwasher. Connect ground wire to green ground connector in

terminal box.

Do not use an extension cord. Failure to follow these instructions can result in death,

fire, or electrical shock.

Remove the ground connector screw and place through the ring terminal of the green ground wire. Reattach and tighten the

ground connector screw.

NOTE: Do not pre-twist stranded wire. Twist on wire connector. Gently tug on wires to be sure both are secured.

Connect wires black to black and white to white, using UL Listed/CSA Approved twist-on wire connectors.

If needed, see website for animated representation of this step. Visit www.maytag.com/electrical under FAQ tab.

Determine Cabinet Opening

Measure height of cabinet opening from underside of countertop to floor where dishwasher will be installed (you will need to measure the lowest point on the underside of the countertop and

the highest point on the floor). Refer to "Dishwasher Height Adjustment Chart" for wheel position and the number of turns

needed.

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 341/2'' [87.6 cm].) If the minimum cabinet opening height is 333/4'' (85.7 cm), a section in the insulation blanket can be removed by cutting along the perforation.

Cut insulation blanket along perforation

Turn both leveler legs to the same height. Put wheels in the required position determined from "Dishwasher Height Adjustment Chart."

Built-up Floors--Add shims as needed

Choose Attachment Option

Excessive Weight Hazard

Use two or more people to move and install dishwasher.

Failure to do so can result in back or other injury.

Using 2 or more people, stand the dishwasher up. IMPORTANT: The dishwasher must be secured to the cabinet.

There are two brackets found in the parts bag. Attach the brackets using Option Number 1 if the countertop is wood,

laminate or another similar surface. If your countertop is marble, granite or another hard surface, install using Option Number 2.

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.

Option 1, Countertop Attachment

Remove the brackets from the package and insert into the open slots on the left and right-hand top of the dishwasher collar as

shown.

Using a pair of pliers, bend the tab down to secure the bracket in place. Repeat this step for the other side.

NOTE: Do not attach the dishwasher. This will be done later.
