Electrical

requirements

Electrical Shock Hazard

• Electrical ground isrequired on this

appliance.

• Do Not ground to gas pipe.

• Do Not modify the power supply cord plug. If it does not fit the outlet, have a proper outlet installed by a

qualified electrician.

• Do Not use an extension cord with

this appliance.

• Do Not have a fuse in the neutral or

grounding circuit. A fuse in the neutral or grounding circuit could

result in an electrical shock.

• Check with a qualified electrician if

you are in doubt as to whether the appliance isproperly grounded.

Failure to follow these instructions

could result in death or serious injury.

If codes permit and a separate ground- ing wire is used, it isrecommended that

a qualified electrician determine that the

grounding path isadequate.

A 120-volt, 60-Hz, AC-only, 15-or 20-ampere, fused electrical supply is required. Time-delay fuse or circuit breaker is recommended. It is

recommended that a separate circuit

serving only this appliance be provided. The dishwasher must be connected with

copper wire only.

Wiring methods

Pick one method to follow, depending upon your dishwasher and local codes.

A.Direct wire method

(cable connecting dishwasher

to a junction box).

Electrical Shock Hazard

Disconnect electrical power at the service panel (fuse box or circuit

breaker box). Failure to do so could result in death

or serious injury.

Recommended grounding

method --

I. Disconnect power supply.

2. Run flexible, armored or non-metallic

sheathed, copper cable (with ground- ing wire) from fused disconnect, circuit breaker or junction box through the 3/4"

cabinet hole to the dishwasher location.

The cable must extend 24 inches from the back wall.

The hole cut through a wood cabinet should be sanded until smooth.

The hole cut through a metal cabinet must be covered with a grommet (Part

No. 302797), available at your local dealer or parts supplier.

A U.L.-listed strain relief or conduit con- nector must be installed at each end of

the power supply cable (at the dish-

washer and at the junction box). Wire

sizes (COPPER WIRE ONLY) must conform

with the rating of the dishwasher.

B.Power supply cord method

(connecting dishwasher to outlet).

Local codes may permit the use of a U.L.-listed, flexible, three-conductor,

power supply cord terminated with a

three-prong, grounding-type plug.

It is recommended that the power

supply cord kit (Part No. 4317824), available at your local dealer or parts supplier, be used. Follow the instructions

packaged with the power supply cord kit. If the cord kit is not available locally,

the flexible power supply cord used must

be a U.L.-listed, three-conductor, 16-

gauge cord that meets the National

Electrical Code, ANSI/NFPA 70- latest edition (*, See Panel A) and all local codes and ordinances. The length of the

power supply cord must not exceed six feet. It must be routed so it does not touch the dishwasher motor or the lower

portion of the dishwasher tub. A strain

relief (Part No. 596171), available at your

local dealer or parts supplier, or a similar

part must be used to secure the flexible

power supply cord to the dishwasher frame or terminal box. The power supply cord must be plugged into a mating,

3-prong, grounding-type wall

receptacle, grounded in accordance with the National Electrical Code

ANSI/NFPA 70 -- latest edition, (*, See Panel A) and all local codes

and ordinances.

Water

requirements

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

pressure.The hotwater heatershould be setto deliver120"Fwater temperature to

the dishwasher forbestresults.

Use 3/8" minimum O.D. copper tubing or

1/2" minimum plastic tubing inlet line.

Dishwasher inlet valve has 3/8"" N.P.T. internal pipe thread.

Drain requirements

20" mJn.

to floor

The drain hose MUSThave a high drain loop, 20 inches minimum ABOVE FLOOR, to prevent backflow or water siphoning out of dishwasher during operation.

NOTE: An air gap MUSTBEUSEDin the high drain loop if the drain hose is connected to house plumbing lower

than 20 inches above the floor.

Drain hose, supplied, meets AHAM DW-1 test standards. Cut 1-1/2" hole in

cabinet wall for drain hose. Additional drain line (a minimum of 1/2""I.D. and no

longer than 20 feet) can be used if

needed.

For your personal safety, this appliance must be grounded. To minimize possible

shock hazard, the power supply cord must be plugged into a mating 3-prong grounding-type wall receptacle, grounded in accordance with National

Electrical Code, ANSI/NFPA 70 -- latest edition (*, See Panel A) and all local

codes and ordinances. See Figure 4. 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.

Panel B

• Cut a 1-1/2" maximum hole for

power supply cord or a 3/4" hole for direct wiring in the cabinet or floor for the electrical wiring to pass through. If

this hole is cut in a wood cabinet, sand the hole until it issmooth. If the hole is cut in a metal cabinet, the hole must

be covered by a grommet (Part No.

302797), available at your local dealer or parts supplier.
