Location Requirements

Dishwasher must be fully enclosed (top, sides, back, and floor)
upon installation. A side panel kit is available from your dealer for
installing your dishwasher at the end of your cabinetry.
An optional moisture barrier accessory is also available for
installing underneath a wooden countertop.
Check location where dishwasher will be installed. The location
must provide:
� Convenient access for loading and unloading dishes. Corner
locations require a 2" (51 mm) minimum clearance between
the side of the dishwasher door and the wall or cabinet.
� Easy access to water, electricity, and drain:
• Grounded electrical supply is required.
• This dishwasher has a water-heating feature and also
requires a connection to a hot water supply line.
• Make sure pipes, wires, and drain hose are within the
shaded area shown in the "Cabinet Opening Dimensions"
section.
• Do not run drain lines, water lines, or electrical wiring where
they can interfere with or contact dishwasher motor or legs.
• Shelter dishwasher and water lines leading to dishwasher
against freezing. Damage from freezing is not covered by
the warranty.
NOTE: 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.
• If installed in new construction, flush the water supply line of
debris before connecting it to the fill valve. If it is not
flushed, debris from the water supply could plug the fill
valve screen.
� A square opening for proper operation and appearance.
� The cabinet front to be perpendicular to floor.

cord, metallic strain relief,

Helpful Hint: If floor at front of opening is not level with floor at
rear of opening, shims may be used to level dishwasher.
NOTE: To avoid shifting during dishwasher operation, shims must
be securely attached to the floor.
� 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.

Drain 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) that meets all current
AHAM/IAPMO test standards, is resistant to heat and
detergent, and fits the 1" (25 mm) drain connector of the
dishwasher.
NOTE: Do not connect multiple drain hoses together.
� Make sure to connect drain hose to waste tee or disposer inlet
above drain trap in house plumbing and 20" (508 mm)
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" (508 mm) above subfloor or
