LEVELING INFORMATION
1. Use a level to
conrm the unit is
level. Level should
be placed along top
edge and side edge
as shown.
2. If the unit is not level, adjust the legs on the corners of
the unit as necessary.
3. Conrm the unit is level after each adjustment and
repeat the previous steps as needed.
INSTALLATION TIP
If the room oor is higher than the oor in the cutout
opening, adjust the rear legs to achieve a total unit rear
height of 1⁄8” (3 mm) less than opening’s rear height.
Shorten the unit height in the front by adjusting the front
legs. This allows the unit to be gently tipped into the
opening. Readjust the front legs to level the unit after it is
correctly positioned in the opening.
INSTALLATION
1. Plug in the power/electrical cord.
2. Gently push the unit into position. Be careful not
to entangle the cord or water and drain lines, if
applicable.
3. Re-check the leveling, from front to back and side to
side. Make any necessary adjustments. The unit’s top
surface should be approximately 1⁄8” (3 mm) below
the countertop.
4. Install the anti-tip bracket.
5. Remove interior packing material and wipe out the
inside of the unit with a clean, water-dampened cloth.

HANDLELESS INTEGRATED DOOR PANEL
The following procedure is designed to provide a finished,
handleless solid panel for a 24" (600 mm) door that
seamlessly integrates with its surrounding cabinetry.
NOTE: Many cabinet manufacturers provide a ready
solution for a handleless, integrated design that can be
easily applied to your model. Consult your cabinet
manufacturer for applicable design and installation details.
The cabinet manufacturer’s solution to this design and
integration detail will often result in an integrated panel
solution wherein the size of the panel may result in a
height dimension taller than what we specify. This can be
achieved provided the additional height is positioned
above the appliance door.
NOTICE
The integrated panel aligns with the surrounding
cabinetry and, due to differences in cabinetry,
may not align perfectly with the door.
The appliance will need up to 34-1/2" (876 mm)
to the underside of the counter to leave room for
leveling adjustments.
A single prepared overlay with insert must not
weigh more than 20 lbs (10 kg).
Integrated Panel Preparation
1. Cut the main panel to the appropriate dimensions
below. For details, see the drawings on the next page.
2. Create the top design for the handleless feature and
the 1/8" (3 mm) notch for the insert(s) indicated on
the Top Detail drawing.
3. Prepare the insert(s) that will back up the handleless
design. Wooden Insert – Cut 1/8" (3 mm) thick
wooden insert(s) to the dimensions below.
4. Optional: Stain or finish panel and wooden insert to
desired stain or color. Be sure to closely follow the
instructions provided by the manufacturer.
NOTICE
If finishing panel or wooden insert, all sides
must be finished to prevent warping.
5. Attach the insert to the panel. Wood glue or equivalent
adhesive should be used to attach insert to panel.
