Step 3: Prepare The Venting Blower; Remove The Mounting Plate - Signature UPMC3084ST Installation Manual

STEP 3: PREPARE THE VENTING BLOwER

● To avoid risk of property damage, unplug the microwave oven or disconnect
power at source by removing fuse or throwing circuit breaker.
● To avoid risk of personal injury, wear protective gloves when handling mounting
plate.
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 room venting. If you want wall-venting
or roof-vented installation, you must change the blower, as detailed below.
Before You Start
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 11.
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.

Remove The Mounting Plate:

1. Remove mounting plate screws from the mounting plate as
shown and discard. See Figure 12.
2. 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.)
3. Locate exhaust adapter, grease filters and hardware packet.
4. At this point, remove any adhesive tape (if there is any), on
the exhaust adapter, the grease filters and the power supply
cord.
Room-Vented (recirculating) Installation:
This oven is shipped assembled for room-vented.
Wall-Vented Installation:
1. Remove one blower unit mounting screw and one or two
blower plate screw(s). 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 thin snips to cut and remove knockouts
"B" from Back plate. Discard knockouts. Be careful not to
distort the plate. See Figure 14.
