Step 3: Prepare The Venting Blower; Remove The Mounting Plate; Roof-Vented Installation - Amana ACO1840AB Installation Instructions Manual

STEP 3: PREPARE THE VENTING BLOWER

•
DO NOT PULL OR STRETCH THE BLOWER WIRING!
Pulling and stretching the blower wiring could result in electrical shock.
Your microwave oven is shipped with the blower assembled for roof venting. If you want wall-venting or
room-vented (recirculating) installation, you must change the fan, as detailed below.

REMOVE THE MOUNTING PLATE:

1. Remove any shipping materials and parts from inside the
microwave oven.
2. Cover the counter top or cooktop with a thick, protective
covering to protect it from damage and dirt. See Figure 10.
NOTE: If you have a free-standing range, disconnect it,
move it onto a piece of cardboard or hardboard and
pull it away from the wall, so that you can get closer
to the upper cabinet and back wall for easier
measuring and drilling.
3. Remove mounting plate screw(s) (1 or 2 screws) from the
mounting plate as shown and discard. See Figure 11.
4. This plate will be used as the rear mounting plate.
(It will be used to locate and mark the mounting holes on
the rear wall.)
5. Locate exhaust adaptor, grease filters and hardware packet.
6. At this point, remove any adhesive tape (if there is any), on
the exhaust adaptor, the grease filters and the power supply
cord.

ROOF-VENTED INSTALLATION:

This oven is shipped assembled for roof-vented. You will need
to install the exhaust adaptor regardless of cabinet.
1. Attach the exhaust adaptor to the blower plate by sliding it
into the guides. See Figure 12.
WALL-VENTED INSTALLATION:
1. Remove one blower unit mounting screw and one blower
plate screw. Remove the blower plate from cabinet. See
Figure 13.
2. Carefully lift the blower unit out of the microwave oven.
3. Use side cutters or tin snips to cut and remove knockouts
"B" from Back plate. Discard knockouts. Be careful not to
distort the plate. See Figure 14.
