Your Safety First
• THIS APPLIANCE MUST BE GROUNDED!
–If there is an electrical short circuit, grounding reduces the risk of electrical shock by providing an escape
wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding
plug.
•Place the plug into a properly installed and grounded outlet. See Figure 3.
•Do not use an extension cord.
•Keep the power cord dry and do not pinch or crush it.
• DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE
POWER SUPPLY CORD GROUNDING PRONG!
This appliance MUST be grounded!
Check with a qualified electrician if you are not sure whether the oven is properly grounded or if you do not
completely understand the grounding instructions.
DO NOT USE A FUSE IN THE NEUTRAL OR GROUNDING CIRCUIT.
SAVE THESE INSTRUCTIONS FOR THE LOCAL ELECTRICAL INSPECTOR'S USE.
• DO NOT EXPOSE YOURSELF TO EXCESSIVE MICROWAVE ENERGY!
–DO NOT try to operate the microwave oven with the door open.
–DO NOT tamper with or defeat the safety interlocks.
–DO NOT place objects between the microwave oven front face and the door.
–DO NOT allow soil or cleaner residue to build up on the flat surfaces around the microwave oven door.
–DO NOT operate the microwave oven if it is damaged.
–The microwave oven door must close properly to operate safely.
–DO NOT USE THE MICROWAVE OVEN:
•If the door is bent.
•If the hinges or latches are broken or loose.
•If the door seals, sealing surfaces or glass is broken.
–DO NOT ATTEMPT TO ADJUST OR REPAIR THE OVEN YOURSELF!
It should be adjusted and repaired by a qualified technician who can check for microwave leakage after
repairing the oven.

Your Safety First
• MAKE SURE YOU HAVE ENOUGH SPACE AND SUPPORT.
–Mount the oven against a flat, vertical wall, so it is supported by the wall. The wall should be constructed of
minimum 2" x 4" wood studding and 3/8" thick drywall or plaster/lath.
–ATTACH (See note on page 5) the two lag screws supporting the oven to a vertical, 2" x 4" wall stud.
–DO NOT mount the microwave oven to an island or peninsula cabinet.
–BE SURE the upper cabinet and rear wall structures can support 150 lbs., plus the weight of any
items you place inside the oven or upper cabinet.
–Locate the oven away from strong draft areas, such as windows, doors, and strong heating vents.
–BE SURE you have enough space. See Figure 4 below for minimum vertical and horizontal clearance.
CAUTION
•Before you begin installing the oven, PLACE A PIECE OF THE CARTON OR OTHER HEAVY
MATERIAL (a blanket) over the countertop or cooktop to protect it. Do not use a plastic cover.
Failure to protect these surfaces could result in property damage.

STEP 1: Prepare The Electrical Connection
Improper grounding could result in electric shock or other personal injury.
1. Locate the grounded electric outlet for this oven in the
cabinet above the oven, as shown in Figure 5.
NOTE: The outlet should be on a circuit dedicated to the
microwave oven (120V, 60 Hz., AC only) with a 15 or 20A
fused electrical supply.
IMPORTANT: If you do not have the proper wall outlet,
you MUST have one installed by a qualified electrician.
2. You will cut the hole for the power supply cord (shown in
Figure 5) later when you prepare the wall and upper cabinet in
Step 4.
NOTE: Do not use an extension cord.
Keep the power cord dry and do not pinch or crush it.
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE POWER SUPPLY CORD
GROUNDING PRONG!

STEP 2: Prepare The Venting System
THIS OVEN MUST BE PROPERLY VENTED!
NOTE: The ductwork you need for outside ventilation is not included with your oven. The standard ductwork
fittings and length are shown in Figure 10, page 9.
You may vent your oven in one of three ways. However, do NOT vent into a wall cavity, an attic, or an unused
area.
Roof-venting If your oven is located on an outside wall near the roof, as in Figures 7 (3 1/4" x 10" duct) and
Figure 9 (6" round duct.)
Wall-venting If your oven is located on an outside wall of your house, as in Figure 6 (3 1/4" x 10" duct) and
Figure 9 (6" round duct.)
Room-venting If your oven is located on an inside wall of your house, as in Figure 8.
NOTE: If you choose the rear exhaust method (roof or wall-venting), be sure there is enough clearance within the
wall for the exhaust duct.
REMEMBER AS YOU INSTALL THE
VENTING:
Keep the length of the ductwork and the number
of elbows to a minimum to ventilate your oven
efficiently. See examples on page 9.
Keep the size of the ductwork the same.
Do not install two elbows together.
Use duct tape to seal all joints in the duct system.
Use caulking to seal the exterior wall or roof
opening around the cap.

STEP 2: Prepare The Venting System
Standard Fittings
NOTE: If the existing duct is round, you must use a rectangular-to-round adapter, with a rectangular 3" extension
duct installed between the damper assembly and the adapter to prevent the exhaust damper’s sticking.
Duct Length
The total length of the duct system, including straight duct, elbows, transitions, and wall or roof caps must not
exceed 140 feet.
For best performance, do not use more than three 90 degree elbows, and keep the length as short as possible.
Below are the standard fittings and their equivalent length in feet.
To calculate the equivalent length of each duct piece used, see the examples below.

STEP 3: Prepare The Venting Blower
Your microwave oven is shipped with the blower assembled for room-vented. You need to adjust the blower if you
want wall-vented or roof-vented installation.
•DO NOT PULL OR STRETCH THE BLOWER WIRING! Pulling and stretching the blower wiring could result in
electrical shock.
1. Remove any shipping materials and parts from inside the
microwave oven. Set them aside for later use.
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.
3. Locate exhaust adaptor, grease filters and hardware packet.
4. At this point, remove any adhesive tape (if there is any), on the
exhaust adaptor, the grease filters and the power supply cord.
