Your Safety First BEFORE YOU START • Proper installation is the installer's responsibility! – Read the entire manual before you begin. The model number label is located on the oven front. See Figure 1. The mounting plate is located on back side of microwave oven. See Figure 2. NOTE: Vent grille appearance varies by model.
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. PROPERLY POLARIZED AND • Do not use an extension cord. GROUNDED OUTLET • Keep the power cord dry and do not pinch or crush it.
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 (See note on page 5) 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 can support 150 lbs.
Parts, Tools, Materials THE FOLLOWING PARTS ARE SUPPLIED WITH THE OVEN: NOTE: Depending on your ventilation requirements, you may not use all of these parts. Damper/duct connector (for roof venting or wall venting installation) Not Actual Size (2 pieces must be assembled as shown) Not used if venting into kitchen.
Parts, Tools, Materials You will need the following tools and materials for the installation: Carton or other heavy material such as a blanket for covering the counter top.
STEP 1: Prepare The Electrical Connection WA 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 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. Upper Cabinet IMPORTANT: If you do not have the proper wall outlet, you MUST have one installed by a qualified electrician. 2.
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 9. WA 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 Figures 7 (3 1/4" x 10" duct) and Figure 9 (6" round duct.
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.
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-vented or roof-vented installation. WA 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. A thick, protective covering REMOVE THE MOUNTING PLATE: 1.
STEP 3: Prepare The Venting Blower WALL-VENTED INSTALLATION: Blower Plate Mounting Screw 1. Remove one blower unit mounting screw and one or several blower plate mounting screw(s). Remove the blower plate from cabinet. See Figure 13. Blower Plate Back Plate Blower Unit 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.
STEP 3: Prepare The Venting Blower ROOF-VENTED INSTALLATION: blower plate mounting screws 1. Remove one blower unit mounting screw and one or several blower plate mounting screw(s). Remove the blower plate from cabinet. See Figure 19. 2. Carefully lift the blower unit out of the microwave oven. blower plate blower unit mounting screw 3. Rotate blower unit 90˚ so the exhaust ports face the top of the cabinet. See Figure 20. Figure 19 4. Place blower unit back into microwave oven. 5.
STEP 4: Prepare The Wall & Upper Cabinet WA R N I N G To avoid personal injury or property damage, do not attempt to install this microwave oven if you cannot find a wall stud. Consult a carpenter or contractor. Measure And Track/Tape Up The Templates 1. Using a plumb line and (metal) measuring tape, find and mark the vertical center line on the back wall, as in Figure 23. 2. Find and mark one or two points where the studs are on the wall. (Studs are normally 16 inches apart).
STEP 4: Prepare The Wall & Upper Cabinet WA R N I N G 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. WA R N I N G 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.
STEP 5: Install The Mounting Plate The Oven Must Be Connected To At Least One 3/16 Hole on Studs 5/8 Hole on Drywall Only Wall Stud. 1. Draw a vertical line on the wall at the center of the 30" wide space. Use the mounting plate as the template for the rear wall. Place the mounting plate on the wall, making sure that the tabs are against the bottom of the cabinet. Line up the notch and center line on the mounting plate to the center line on the wall. Minimum 66" From the Floor For WallVented Only 2.
STEP 5: Install The Mounting Plate For Wall-Vented Make the box cutout for the rear wall duct. – 1-piece mounting plate: Using a pencil, put dots through slots F and G, and through holes H and I. 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.
STEP 6: Attach The Oven To The Wall WA R N I N G To avoid risk of personal injury or property damage, you will need two people to install this microwave oven. 1. Carefully lift microwave oven and hang it on support tabs (See Figure 27) at the bottom of the mounting plate.Reaching through upper cabinet, thread power supply cord through the power supply cord hole in the bottom of the upper cabinet. See Figure 31. Power Cord Power Cord Hole 2.
STEP 6: Attach The Oven To The Wall 5. Roof venting installation: See Figure 33. Install ductwork through the vent opening in the upper cabinet. Complete the venting system through the roof according to the method needed. See Prepare The Venting System STEP 2. Use caulking gun to seal the exterior roof opening around the exhaust cap. See Figure 7 on page 8. 6. Use the power supply cord clamp to bundle the power supply cord.
