WARNING

FOR YOUR SAFETY:

• You will need TWO people to install this oven. It is heavy and could cause personal injury if not handled
properly. The dimensions of the oven are as follows:

Height : 16-7/16 inches
Width : 29-15/16 inches

Depth : 15-3/8 inches
Weight : 62 pounds

• AVOID ELECTRICAL SHOCK!

- Before you drill into the wall, note where electrical outlets are and where electrical wires might be

concealed behind the wall.
YOU COULD GET AN ELECTRIC SHOCK it you contact electrical wires with your drill bit.

- Locate and disconnect the power of any electrical circuits that could be affected by installing this oven.

IF YOU DO NOT DISCONNECT THE POWER, YOU COULD GET AN ELECTRIC SHOCK.

• ELECTRICAL RATING OF THIS OVEN : 120V, 60Hz.

- You need a 120V, 60Hz, AC only, 20A, fused electrical supply (located in the cabinet above the
microwave as close as possible to the microwave circuit) serving only the microwave.

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 net pinch or crush it.

• DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE
THE POWER SUPPLY CORD GROUNDING PRONG!

This appliance MUST be grounded!

_, WARNING _,

If you use the grounding plug improperly, you risk electric shock!

- 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.

PROPERLY POLARIZED AND

GROUNDED OUTLET

YOUR SAFETY FIRST

• MAKE SURE YOU HAVE ENOUGH SPACE AND SUPPORT.

- Mount the oven against a flat, vertical wall, so that 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 AT LEAST ONE of 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 are able to support 150 Ibs., 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.

WARNING

If you do not mount the oven as instructed, you risk personal injury and/or

property damage.

STEP 1: PREPARE THE
ELECTRICAL CONNECTIONS

_k WARNING _k

AVOID ELECTRICAL SHOCK! THIS APPLIANCE MUST BE GROUNDED!

1. Locate the grounded electric outlet for this oven in the
cabinet above the oven, as shown in Figure 4 Detail.

NOTE: The outlet should be on a circuit dedicated to the

_, WARNING _,

Improper grounding could result in electric shock or other personal injury.

• DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE POWER SUPPLY

CORD GROUNDING PRONG!

• This appliance MUST be grounded!

STEP 2:
PREPARE THE VENTING SYSTEM

NOTE: The ductwork you need for outside ventilation is not included with your oven. The standard ductwork

fittings and length are shown in Figure 9, page 9.

WARNING - FIRE HAZARD A

I THIS OVEN MUST BE PROPERLY VENTED!

You may vent your oven in one of three ways:

Roof Venting If your oven is located on an outside wall near the roof, as in Figure 6 (3-1/4" x 10" duct) and

Figure 8 (6" round duct.)

Wall Venting If your oven is located on an outside wall on the first floor of your house, as in

Figure 5 (3-1/4" x 10" duct) and Figure 8 (6" round duct.)

Room Venting If your oven is located on an inside wall of your house, as in Figure 7.

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.

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 sticking.

DUCT LENGTH

The total length of the duct system, including straight duct, elbows, transitions, wall or roof caps must not
exceed the equivalent of 140 feet.

For best performance, do not use more than three 90 degree elbows.
Below are the standard fittings and their equivalent length in feet.

3-1/4"x10" to 6" = 5ft.

90° elbow = 1Oft.

3-1/4"x10" roof cap = 24ft.

3-1/4"x10" wall cap
= 40ft.

45 ° elbow = 5ft. 3-1/4"x10" fiat elbow

3-1/4"x10" 90° elbow = 25ft.

STEP 3:
PREPARE THE VENTING BLOWER

Your microwave oven is shipped with the blower assembled for room venting (recirculating). You need to adjust
the blower if you want wall vented or roof vented installation.

WARNING A

ELECTRICAL SHOCK HAZARD! UNPLUG UNIT BEFORE WORKING ON IT.

• DO NOT PULL OR STRETCH THE BLOWER WIRING! Pulling and stretching the blower wiring could result

in electrical shock.

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 2 screws from the mounting
plate as shown and discard them.
(See Figure 11.)

4. The mounting plate will also 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.
