Step 2: Preparing the Cabinet
• The cabinet cutout dimensions are shown in
Figure 1.
• It is a good practice when the microwave oven is
installed at the end of a cabinet run, adjacent to a
perpendicular wall or cabinet door, to allow at least
1/2"
(12.7 mm) space between the side of the trim
and wall or door.
• Your microwave oven can be installed into a
cabinet or wall by itself or above any of the
following Thermador wall ovens: C271, C301,
CM301, S301, SC301. Or,
Thermador Warming
Drawers WD27 and WD30 (see Figures 2a and
2b).
• Outlet can be located anywhere within the shaded
area as indicated in Figure 1.

WARNING: Improper grounding can result in risk of electric shock.
Step 4: Preparing the Trim Kit
(1) Attach the two vertical side trim brackets to the template as shown in Figure 3. Use two (2) #8 x
3/8, Type B screws on each side.
(2) Mark the center line on bottom edge of the cutout.
(3) Hold template in front of cabinet cutout. Line up the bottom of the template with the bottom of the
cutout. Align the template notch with the centerline of the cutout.
(4) Mark the location of the three holes in the trim brackets on both sides. Set brackets and tem-
plate aside.
(5) Drill 1/16" diameter starter holes.
(7) Remove template from trim brackets and discard. Set brackets and screws aside to be installed
later in the process.
Note: DO NOT attach trim brackets at this time. Continue to
Step 5: Installing the Ducts.
Step 3: Preparing the Electric
The Thermador microwave oven is equipped with a grounded cord. The wall receptacle must be
installed and grounded in accordance with the national electrical code. It can be installed anywhere in
the shaded area in Figure 1 (previous page). Electrical connections and grounding must comply with all
applicable local codes.
The electrical requirements for a separate circuit serving only this microwave oven are: 120V, 60Hz,
15Amp.

ner in cabinet cutout.
2. Reach past microwave on left side to insert
electrical cord into outlet.
3. Slide oven the rest of the way into the cabi-
net. Position microwave in cabinet so that
base pan center hole aligns with cabinet
centerline. When properly installed, the front
end of pan will be flush with the front edge
of the shelf.
4. Open the microwave door to access three
holes on the base pan below the microwave.
Drill 1/16" holes through the three (3) base
pan holes into the cabinet cutout bottom.
Fasten base pan to shelf with three 3 #8 x
3/8 Type A screws.
11. Install both vertical trim brackets on the cabi-
net using three (3) #8 x 3/8 Type A screws
on each side. The flanges on the ends of
the brackets should be inside the cabinet.
