[. . . ] It is heavy and could cause personal injury if not handled properly. · 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 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. ­2­ 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. [. . . ] Use duct tape to seal all joints in the duct system. Use caulking to seal the exterior wall or roof opening around the cap. Room Venting Roof Cap Cabinet 6"min diameter Round Duct Elbow 3 1/4" to Round Duct Transition Wall Cap Oven 3 1/4" to Round Ductwork Transition Figure 8 Figure 9 ­8­ 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. 1 2 3 3 1/4" x 10" to 6" = 5 ft. 4 5 3 1/4" x 10" roof cap = 24 ft 6 3 1/4" x 10" 90° elbow = 25 ft 7 90°elbow = 10 ft 3 1/4" x 10" wall cap = 40 ft 45°elbow = 5 ft 3 1/4" x 10" flat elbow = 10 ft Figure 10 To calculate the equivalent length of each duct piece used, see the examples below.

You need to adjust the blower if you want wall-vented or roof-vented installation. WARNING ELECTRICAL SHOCK HAZARD!Measure the bottom of the upper cabinet frame. Trim the edges A, B, and C on the upper cabinet template so that the template will fit on the bottom of the upper cabinet. If upper cabinet has a recessed frame, trim the template so it fits inside the recessed area. Align the centerline of the upper cabinet template with the centerline of the mounting plate, then securely tape or tack the upper cabinet template in place. See Figure 24. Mounting Plate (1-piece Mounting Plate) Upper Cabinet Template Mounting Plate (3-piece Mounting Plate) Figure 24 ­ 13 ­ STEP 4: Prepare The Wall & Upper Cabinet WARNING To avoid risk of personal injury, electrical shock or death: Note where electrical outlets and electrical wires are before you drill into the wall. Locate and disconnect power to any electrical circuits that could be affected by installing this oven. WARNING To avoid risk of personal injury, electrical shock or death, cover the edge of the power supply cord hole with the power supply cord bushing. Drill The Holes In The Wall And Upper Cabinet. 1. If there is a stud, drill a 3/16" hole for lag screws. If there is no stud, drill a 3/4" hole for toggle bolts. Make sure to use at least 2 lag screws in a stud, and 4 toggle screws in the drywall or the plaster. Drill a 3/8" hole at points J and K on the upper cabinet template. NOTE: If the bottom of the upper cabinet is recessed 3/4" or more, you will need 2"x 2" filler blocks (not included) to provide additional support for the bolts. [. . . ] Remove the mounting plate and draw lines extending through the points. This will give the location and size of the box cutout for the rear wall duct. (Figure 29) ­ 3-piece mounting plate: Use the wall template to determine the location and size of the box cutout for the rear wall duct. Attach the exhaust adaptor to the rear mounting plate (back plate) wall side. [. . . ]
