OVER THE RANGE MICROWAVE OVEN/HOOD SYSTEM INSTALLATION INSTRUCTIONS Please read all instructions thoroughly before installing the Microwave Oven/Hood System. Two people are recommended to install this product. If a new electrical outlet is required, its installation should be completed by a qualified electrician before the Microwave Oven/Hood is installed. See 3 ELECTRICAL GROUNDING INSTRUCTIONS on page 2. 1 MOUNTING SPACE This Microwave Oven/Hood requires a mounting space on a wall as shown in Figure 1. It is designed to be used with standard 12-inch wall cabinets. If the space between the wall cabinets is 36 or 42 inches, a Filler Panel Kit can be used to fill the gap. The metal filler panels come in 3-inch wide pairs. One set is needed for a 36-inch opening and 2 sets for a 42-inch opening. White and black are available. See page 8 for ordering information. The Filler Panel Kit should be installed before the Microwave Oven/Hood is installed. 12" 30" At least 2" Backsplash 30" or more from cooking surface 15 1/2" 66" or more from floor Figure 1 1 2 WALL CONSTRUCTION This Microwave Oven/Hood should be mounted against and supported by a flat vertical wall. The wall must be flat for proper installation. If the wall is not flat, use spacers to fill in the gaps. Wall construction should be a minimum of 2" x 4" wood studding and 3/8" or more thick dry wall or plaster/lath. The mounting surfaces must be capable of supporting weight of 110 pounds--the oven and contents--AND the weight of all items which would normally be stored in the top cabinet above the unit. The unit should be attached to a minimum of one 2" x 4" wall stud. To find the location of the studs, one of the following methods may be used: A. Use a stud finder, a magnetic device which locates the nails in the stud. B. Use a hammer to tap lightly across the mounting surface to find a solid sound. This will indicate stud location. The center of the stud can be located by probing the wall with a small nail to find the edges of the stud and then placing a mark halfway between the edges. The center of any adjacent studs will normally be 16" or 24" to either side of this mark. 3/8" Dry Wall or Plaster/lath 16" or 24" 2"x 4" Wood Studs Figure 2 3 ELECTRICAL GROUNDING INSTRUCTIONS This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces risk of electric shock by providing an escape wire for the electric current. WARNING - Improper use of the grounding plug can result in a risk of electric shock. The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG. The power supply cord and plug must be connected to a separate 120 Volt AC, 60 Hz, 15 Amp, or more branch circuit, single grounded receptacle. The receptacle should be located inside the cabinet directly above the Microwave Oven/Hood mounting location. NOTE: 1. If you have any questions about the grounding or electrical instructions, consult a qualified electrician or serviceperson. 2. Neither Sharp nor the dealer can accept any liability for damage to the oven or personal injury resulting from failure to observe the correct electrical connection procedures. Opening for Power Cord Ground Receptacle Figure 3 2 4 HOOD EXHAUST DUCT When the hood is vented to the outside, a hood exhaust duct is required. All ductwork must be metal; absolutely do not use plastic duct. Check that all connections are made securely. Please read the following carefully: Exhaust connection: The hood exhaust has been designed to connect to a standard 3-1/4" x 10" rectangular duct. If round duct is required, a rectangular-to-round adapter must be used. Rear exhaust: If a rear or horizontal exhaust is to be used, care should be taken to align the exhaust with the space between the studs, or wall should be prepared at the time it is constructed by leaving enough space between wall studs to accommodate exhaust. Maximum duct length: For satisfactory air movement, the total duct length of 3-1/4" X 10" rectangular or 6" diameter round duct should not exceed 140 feet. Elbows, adapters, wall, roof caps, etc. present additional resistance to air flow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total length, add the equivalent lengths of all transitions and adapters plus the length of all straight duct sections. Figure 4 shows the approximate feet of equivalent length of some typical ductwork parts. Use the values in parentheses for calculating air flow resistance equivalent, which should total less than 140 feet.

See Figure 12 on page 5. The Hood Fan Unit is now rotated for vertical exhaust operation. 6. Attach the Exhaust Damper Assembly 8 to the fan cover on the top of the outercase cabinet after mounting the oven. To attach the Exhaust Damper Assembly, refer to MOUNTING OVEN TO THE WALL, Step 7 on page 7. Figure 14 9 OVEN INSTALLATION THIS OVEN CANNOT BE PROPERLY INSTALLED WITHOUT REFERRING TO THE MOUNTING INSTRUCTIONS FOUND ON BOTH TEMPLATES. THE NEXT STEP IS TO READ AND FOLLOW MOUNTING INFORMATION ON BOTH TOP CABINET AND WALL TEMPLATES. NOTE: THIS OVEN SHOULD BE ATTACHED TO AT LEAST ONE WALL STUD. See WALL CONSTRUCTION on page 2. MOUNTING PLATE 1. Separate 4 Toggle Bolts 2, packed in the INSTALLATION HARDWARE, from the Toggle Nuts. 2. Use Wood Screws 1 to attach Mounting Plate to the stud or studs. Use Toggle Bolts to attach Mounting Plate through the holes at A, B, C and D; UNLESS THOSE HOLES ARE LOCATED ON THE STUD. Insert one Toggle Bolt into A, B, C and D where appropriate (these correspond to the holes of the Wall Template) and put the Toggle Nuts onto the Toggle Bolts. Figure 15. Refer to instructions in Wall Template. 3. Position the Mounting Plate with the Toggle Bolts attached at the wall location and insert Toggle Nuts and Bolts through the holes in the wall with the Toggle Nuts closed. Figure 16. Use Wood Screws 1 to attach the Mounting Plate to studs. NOTE: Before insertion, be sure you leave a space more than the thickness of the wall between the Mounting Plate and the end of each of the Toggle Nuts (in the closed position). If you do not leave enough space, the Toggle Nut will not be able to open on the other side of the wall. Also, once a Toggle Nut opens, it cannot be withdrawn from the hole; therefore make sure all of the Toggles are in the correct position before insertion. 4. Align the Mounting Plate carefully and hold in position while tightening Toggle Bolts. Pull Toggle Bolt toward you and turn clockwise to tighten. Figure 17.
