Charcoal filter kit : Charcoal filter kit is needed for recirculating exhaust installation.
Filler panel kit : If space between cabinets is greater than 30 inches, filler panel kit may be used to fill in gap between microwave oven and cabinets.

Hood Exhaust Duct

Outside ventilation requires hood exhaust duct. Use only metal duct. Read the following carefully.
Exhaust Connection: Hood exhaust has been designed to mate with standard 3 1/4 inch x 10 inch rectangular duct. If round duct is required, rectangular-to-round transition adaptor must be used. Do not use less than 6 inch diameter duct.
Rear Exhaust: If rear or horizontal exhaust is to be used, care should be taken to align exhaust with space between studs.
Maximum Duct Length: Total duct length of 3 1/4 inch x 10 inch rectangular or 6 inch diameter round duct should not exceed 140 equivalent feet for satisfactory air movement.
Elbows, Transitions, Wall and Roof Caps, Etc. Elbows, transitions, wall and roof caps, etc., create additional resistance to airflow and are equivalent to a section of straight duct. When calculating total duct length, add equivalent lengths of all transitions and adaptors, plus length of all straight duct sections. Chart below shows approximate feet of equivalent length of some typical ducts.
If rectangular-to-round transition adaptor is used, bottom corners of damper will have to be cut to fit, using tin snips, in order to allow free movement of damper.

D. Mounting Bracket Assembly to Wall
Microwave oven needs to be mounted against and supported by flat, vertical wall. Wall construction should be minimum of 2 inch x 4 inch wall studding and 3/8 inch or more, thick drywall or plaster/lath. Microwave oven must be attached to minimum of one 2 inch x 4 inch wall stud.

Find studs, using one of following methods:
- Stud finder–magnetic device which locates nails.
- Use hammer to tap lightly across mounting surface to find solid sound. This will indicate stud location.
- Note: After locating stud or studs, stud center can be found by probing wall with small nail to find edges of stud. Place mark halfway between edges. Center of any adjacent stud should be 16 inches or 24 inches from mark.
Draw line down middle of studs. Microwave must be connected to at least one wall stud.
Draw vertical line on wall, at center of 30 inch wide space.
Use mounting plate as template for rear wall. Place mounting plate on wall, verify tabs are against bottom of cabinet. Line up notch and center line on mounting plate to center line on wall.
While holding mounting plate with one hand, draw circles on wall at holes A and B, marked on mounting plate. See diagram below. Holes A and B are shown by arrows stamped into mounting plate and must be used for mounting. If holes are not used, improper installation will occur. Use toggle bolts through these holes unless one lines up with stud. Use wood screw for stud. Set mounting bracket aside.
Draw third circle through one of top or bottom holes to match location of stud.
NOTE: For outside back exhaust, microwave oven requires rear wall cutout opening for rear wall duct. See “Preparing Rear Wall Cutout Opening for Outside Back Exhaust” section.
Drill holes through circles. Diameter of holes should be 5/8 inch for toggle bolts and 3/16 inch for wood screws on studs. Use at least 1 wood screw in stud, and 2 toggle bolt assemblies into drywall or plaster.
Attach mounting plate to wall.
Remove toggle assembly from screws. Insert screws into mounting plate and replace toggle assembly to 3/4 inch past screw ends. Insert toggle assembly into holes in wall to mount bracket. Pull forward on bracket to tighten toggle bolts.

If installation is other than outside back exhaust, proceed to step F.

E. Preparing Rear Wall Cutout Opening for Outside Back Exhaust

Place mounting plate against rear wall, as described in diagram at left.
Using pencil, draw dots through holes D and E, and in tips of notches G and F. Mark straight edges of H and I for bottom line. This will give location and size of box cutout for rear wall duct.
Verify exhaust adaptor (with damper) is squared up in house duct and lines up with holes in mounting plate.
Attach 28 inch foam tape to front of mounting plate, around both exhaust openings where it will touch microwave oven.
NOTE : Exhaust must be aligned within space between studs.

F. Mounting Microwave Oven

Locate grease filters packed separately and set aside. Thread power cord through hole, or slot, in bottom of top cabinet. Keep cord tight throughout step 2.
Install microwave by sliding onto arms of mounting plate. Push microwave oven flush to wall. Verify cord is tight
Attach microwave oven to top cabinet. Use filler block if cabinet front hangs below cabinet bottom shelf.
Insert 2 screws with washers through top cabinet holes and tighten to top of microwave oven. (While tightening screws, lift front side of microwave oven and push toward wall.)
Install rectangular washer under microwave oven for extra stability. Rectangular slot is located under microwave oven, inside left grease filter area.
Use rectangular washer to mark hole for drilling in left side rectangular slot. Place washer in slot by grasping “ears” on washer to center in opening. Mark location of hole on rear wall with pencil. Center carefully to assure good fit.
Drill small pilot hole with 1/8 inch drill to determine if stud is behind hole. If stud is found, drill 3/16 inch diameter hole for wood screw; if no stud is found, drill 5/8 inch diameter hole for toggle bolt.
If stud is found, use wood screw to attach rectangular washer lightly to wall. Twist washer 90° to lock before tightening. If no stud is found, use toggle bolt to attach rectangular washer lightly to wall. Twist washer 90° to lock before tightening.
Install grease filters.
For top exhaust, open top cabinet and attach exhaust adaptor to microwave oven through cabinet bottom. For front-to-back or side-to-side adjustment, slide exhaust adaptor as needed.
Twist exhaust adaptor to fit under flaps of blower plate. Verify damper moves freely. Square corner on hinge ends.
Pull house duct down to connect to exhaust adaptor.
