DISHWASHERSAFETY

Your safety and the safety of others are very important.

We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety

messages.

This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages will follow the safety alert symbol and either the word "DANGER" or "WARNING."

These words mean:

You can be killed or seriously injured if you don't immediately

follow instructions.

You can be killed or seriously injured if you don't follow instructions.

All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can happen if the instructions are not followed.

You Need to:

• Slowly open dishwasher door while someone grasps the rear of the dishwasher. Remove shipping materials, drain hose and

lower rack. Close dishwasher door until latched.

NOTE: Each dishwasher is tested at the factory and may contain some residual water in the tub as a result of the test.

• Observe all governing codes and ordinances.

• Install this dishwasher as specified in these instructions.

Tip Over Hazard

Do not use dishwasher until completely installed. Do not push down on open door.

Doing so can result in serious injury or cuts.

• Installation should be performed by a qualified service technician. The dishwasher must be installed to meet all

electrical and plumbing national and local codes and ordinances.

Care shall be exercised when the appliance is installed or removed, to reduce the likelihood of damage to the power-supply

cord. WARNING: To reduce the risk of electric shock, fire, or injury to

persons, the installer must ensure that the dishwasher is completely enclosed at the time of installation.

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: Besure 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.

not provided)

Measure overall length of copper tubing for the water supply line.

Attach the water supply line (copper tubing or flexible braided line) to the hot water line using a connection configuration that is in compliance with local codes and ordinances. The water supply to

the dishwasher should have a manual shutoff valve located under the sink.

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.

Route water line and tape it to the floor in area shown. This will keep it from moving when dishwasher is moved into cabinet

opening.

IMPORTANT: Always use a new drain hose. Check local codes to determine whether an air gap is required.

If needed, drill a 1Y2"(3.8 cm) diameter hole in cabinet wall or side of the opening closest to the sink.

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.

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.
