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.	PROPERLY POLARIZED AND
• Keep the power cord dry and do not pinch or crush it.	GROUNDED OUTLET
• DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE
POWER SUPPLY CORD GROUNDING PRONG!
This appliance MUST be grounded!

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 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 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.

W A R N I N G

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

STEP 1: PREPARE THE

ELECTRICAL CONNECTIONS

W A R N I N G

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.

NOTE: The outlet should be on a circuit dedicated to the microwave oven 120V, 60Hz., AC only with a 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 power-supply-cord hole (shown in

Figure 4) 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.

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.

W A R N I N G -F I R E H A Z A R D

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 Figures 6 (31/4" x 10" duct) and 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 (31/4" 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.

	Figure 5	Figure 6

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 SYSYTEM

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, 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.

STEP 3:

PREPARE THE VENTING BLOWER

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

W A R N I N G

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 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.)

STEP 3:

PREPARE THE VENTING BLOWER

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.

4.Reassemble the blower wire. See Figure 15.

5.Rotate the unit so that the exhaust ports face the rear of the cabinet. See Figure 16. When you insert blower unit, blower wire must be like figure 16.

6.Place blower unit back into cabinet. Check that the exhaust ports face towards the rear of the cabinet. See Figure 17.

7.Reattach the blower plate to cabinet so the exhaust ports and blower plate opening are aligned. Attach with one blower unit mounting screw and then one blower plate mounting screw. See Figure 18.
