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, ANSVNFPA 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.

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, ANSVNFPA 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.

Water

requirements

The hot water line to the dishwasher

must provide between 15-l 20 psi water

pressure. The hot water heater should be

set to deliver 12O’F water temperature to

the dishwasher for best results.

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

l/2” minimum plastic tubing inlet line.

Dishwasher inlet valve has 3/8” N.P.T.

internal pipe thread.

Drain

requirements

20” min

The drain hose MUST have a high drain

loop, 20 inches minimum ABOVE FLOOR,

to prevent backflow or water siphoning

out of dishwasher during operation.

NOTE: An air gap MUST BE USED in

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 l-l /2” hole in

cabinet wall for drain hose. Additional

drain line (a minimum of l/2” I.D. and no

longer than 20 feet) can be used if

wiring location

Cut a 1-l /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 is smooth. 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.

If a power supply cord is used, install

wall receptacle on rear or side wall of

a cabinet next to dishwasher opening.

If power supply cable is used, install a

3/4” U.L.-listed strain relief or conduit

connector to connect the flexible

armored or non-metallic sheathed,

copper cable (with grounding wire) to

the fused disconnect, circuit breaker or

junction box. Run the cable through the

hole in the cabinet opening. The cable

should extend 24 inches from the

back wall.
