Do Not run water or drain lines or

electrical wiring where they can

cross in front of or contact dishwasher motor or legs. Do Not install dishwasher over carpeted flooring.

Do Not kink the power supply wire between the dishwasher and

cabinet. Protect dishwasher and water lines

leading to dishwasher against freezing. Damage from freezing is not covered by the warranty.

Proper electrical, drain and water supply lines must be available or must be installed, as specified,

within the shaded area. See

"Electrical requirements,""Water requirements," and _Drain

requirements +sections.

Important: Observe all governing codes and

oralnances.

It is recommended that the electrical, drain and water supply

lines be located as close to the rear wall as possible.

Check the location where the dishwasher will be installed. The

location must provide:

• easy access to water, electricity and drainage lines.

• convenient loading -- the best location isto the left or right of the

kitchen sink.

• square opening for proper dishwasher operation and appearance.

• cabinet front that is perpendicular to the floor.

• protection so that the water inlet valve and drain cannot freeze.

• 1/4" (0.64 cm) minimum clearance

between the motor and the

flooring to prevent the motor from

overheating.

For installations where the dishwasher will be left unused and

subject to freezing temperatures, see the "Storing Your Dishwasher +or

"Moving or winterizing your

dishwasher" section of the dishwasher Use and Care Guide.

Electrical requirements

Electrical Shock Hazard

Electrically ground dishwasher. Connect ground wire to green

ground connector in terminal box. Do not use an extension cord.

Failure to do so can result in death, fire, or electrical shock.

Check with a qualified electrician if

you are not sure dishwasher is

properly grounded. It is the customer's responsibility:

To contact a qualified electrician. To assure that the electrical

installation is adequate and in conformance with all national

and local codes and ordinances.

A 120-volt, 60-Hz, AC-only,

15-ampere, fused electrical supply is

required. A time-delay fuse or circuit breaker is recommended. It is

recommended that a separate circuit serving only this dishwasher be provided.

The dishwasher must be connected with copper wire only, in

accordance with all national and local codes and ordinances.

Grounding instructions

Dishwasher must be connected to a grounded metal, permanent wiring

system, or an equipment-ground conductor must be run with the circuit conductors and connected

to the equipment-ground terminal or lead on the dishwasher.

Do not ground to a gas pipe. Do not connect dishwasherto

electrical supply untildishwasheris permanently grounded.

Do not have a fusein the neutralor ground circuit.

Wiring methods

Electrical Shock Hazard

Disconnect electrical power at the

fuse box or circuit breaker box

before installing dishwasher. Failure to do so can result in death

or electrical shock.

Pick one method to follow depending on your

dishwasher and local codes.

A= Direct wire method

(cable connecting

dishwasher to a junction box)

If your dishwasher model is not equipped with a power supply cord go to Step 1.

If a power supply cord is attached to dishwasher but dishwasher must

be directly wired to meet local codes...

The power supply cord must be removed and dishwasher wired directly. To direct wire this product,

order kit #4317979. Electrical connections must be contained

within the terminal box and meet all national and all local codes and ordinances.

The hot water line to the dishwasher must provide between 15-120 psi

(103-827 kPa) water pressure.

The hot water heater should be set to deliver 120°F (49°C) water

temperature to the dishwasher for

with a power supply cord. If a power supply cord is not supplied, Power

Supply Cord Kit (Part No. 4317824)

is available at your local dealer or parts supplier. Follow the instructions packaged with the power supply cord kit. If the kit is not available locally, the power supply cord used must be

minimize possible shock hazard, the power supply cord must be plugged into a mating 3-prong ground-type

wall receptacle, grounded in

accordance with all national and local codes and ordinances.

If a mating wall receptacle is not available, it is the personal responsibility and obligation of the customer to have a properly grounded 3-prong wall receptacle installed by a qualified electrician. The receptacle should be installed

on the rear or side wall of the cabinet next to dishwasher

opening.

Drain requzrements

The drain hose must connect to the house plumbing at a minimum of 20

inches (50.8 cm) above the floor. Thiswill prevent backflow or water siphoning out of dishwasher during operation.

If the drain hose is routed to a connection point less than 20 inches

(50.8 cm) above the floor, the drain hose must form a loop 20 inches

(50.8 cm) above the floor. An air gap must be used in the high drain

loop. Do Not kink drain hose and copper

tubing. Do Not use drain hose or fittings that

are less than I/2 inches (1.3 cm) I.D.

If connection to an air gap is required, an Air Gap Kit (Part No.

300096) is available from your local parts dealer. If another brand air gap is used, it should be checked to

make sure it allows for the same water flow.

Install air gap according to kit instructions.

If connecting to a dlsposer, remove disposer knockout or plug before connecting drain line.
