• The ductwork you need for the installation is not included. All wall and roof caps must have a back-draft damper. -10 INSTALLATION STEP 1" PREPARE THE ELECTRICAL CONNECTIONS _, WARNING To avoid risk of personal injury, electrical shock or death, this oven must be grounded. • DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE POWER SUPPLY CORD GROUNDING PRONG! 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. Upper I NOTE: The outlet should be on a circuit dedicated to the Cabinet 7, microwave oven (120V, 60Hz., AC only) with a 15 or 20A fused electrical supply. ............. ............................... -Grounded Outlet IMPORTANT: If you do not have the proper wall outlet, you MUST Q ( Inside Cabinet ) 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 Power-Supply-Cord Hole Step 4. NOTE: Do not use an extension cord. Figure 4 Keep the power cord dry and do not pinch or crush it. -11 INSTALLATION STEP 2: PREPARE THE VENTING SYSTEM WARNING To avoid risk of personal injury, property damage, or fire this microwave 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 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 6 (31/4" X 10" duct) and Figure 8 (6" round duct.) Wall-venting If your oven is located on an outside wall 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.

DUCT LENGTH The total length of the duct system, including straight duct, elbows, transitions, and wall or roof caps must not exceed the equivalent of 140 feet. For best performance, do not use more than three 90 degree elbows, and keep length as short as possible. Below are the standard fittings and their equivalent length in feet. 3 3 1/4"x10" 3 1/4"x10" roof 3 1/4"x10" 90 ° to 6"=5ft. elbow=25ft. cap=24ft. 567 3 1/4"x10" 3 1/4"x10" 90 ° elbow wall cap 45 ° elbow flat elbow = 1Oft. =5ft. =40ft. =10ft.

Pulling and stretching the blower wiring could result in electrical shock. Your microwave oven is shipped with the blower assembled for roof venting. If you want wall-venting or room-vented (recirculating) installation, you must change the fan, as detailed below. REMOVE THE MOUNTING PLATE: thick, protective 1. Remove any shipping materials and parts from inside the microwave oven. 2. Cover the counter top or cooktop with a thick, protective covering covering to protect it from damage and dirt. See Figure 10. NOTE: If you have a free-standing range, disconnect it, Figure 10 move it onto a piece of cardboard or hardboard and pull it away fro...
