For Your Safety

•This oven should not be installed or located by anyone except properly qualified service personnel.

•You will need TWO people to install this oven. It is heavy and could cause personal injury if not handled properly.

•Avoid Electric 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 if you contact electrical wires with your drill bit.

–Locate and disconnect the power to 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 AC 60Hz.

–You need a DEDICATED 120V, 60Hz, AC only, 15 or 20A, fused electrical supply (located in the cabinet above the microwave as close as possible to the microwave) serving only the microwave.

•THIS APPLIANCE MUST BE GROUNDED!

–If there is an electrical short circuit, grounding reduces the risk of electric 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. Failure to follow this instruction may cause a fire hazard.

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

This appliance MUST be grounded!

STEP 1: Prepare The Electrical Connection

wW A R N I N G

AVOID ELECTRIC 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 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.

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 10, page 8.

wW A R N I N G

THIS OVEN MUST BE PROPERLY VENTED!

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 Figure 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.

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 8.

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.

After installation, you should check outside hood opening and operation.

When you install the oven, please refer to the Installation Manual.

For the outside hood opening position and size refer to the upper cabinet template or rear wall template.

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.

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-venting or roof-vented installation.

wW A R N I N G

ELECTRIC 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 electric 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 the 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.

•Do not remove the packing tape on the slide-out vent.

NOTE: Set the product down on a flat surface only.

ROOM-VENTED INSTALLATION:

This oven is shipped assembled for room-vented.

You need togo to STEP 4: PREPARE THE WALL & UPPER CABINET located on page 13 .

wW A R N I N G

FIRE HAZARD! CORRECTLY INSTALL THE VENT FAN BEFORE USE .

• When changing the vent fan position for a rear wall vent or roof vent:

1.Properly align the ventilation fan openings and blower plate knockouts.

2.Ventilation fan openings should be completely exposed to the outside.

3.After installation, check the air ventilation path. Refer to page 7 Figures 6-8 for proper vent selection.

•Improper installation can cause problems such as:

1.Inability to assemble blower plate or ventilation motor correctly.

2.Abnormal noise during product operation.

3.Weak ventilation.

4.Product overheating - possibility of product breakdown or fire.

STEP 3: Prepare The Venting Blower

WALL-VENTING INSTALLATION:

1.Remove one or two blower unit mounting screw(s) and one or several blower plate mounting screw(s). Remove the blower plate from the cabinet. See Figure 12.

2.Carefully lift the blower unit out of the microwave oven. See Figure 13.

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 and reinstall the blower unit so that the exhaust ports face the rear of the cabinet and are aligned with the rear cut-outs. See Figures 16 & 17.

6.Reattach the blower plate to microwave oven so the exhaust ports and blower plate opening are aligned. Attach with one blower unit mounting screw and then one or several blower plate mounting screw(s). See Figure 18.

7.Insert the tabs on each side of the damper into the holes

at the inside rear of the adaptor.

Attach the exhaust adaptor to the back plate wall side. Push in securely until it is past the top locking tabs and in the lower locking tabs. Take care to assure

the damper hinge is installed so that it is at the top and that the damper swings freely. See Figure 19.
