PLACEMENT OF THE MOUNTING PLATE

A. REMOVING THE MICROWAVE OVEN FROM THE CARTON/ REMOVING THE MOUNTING PLATE

  1. Remove the installation instructions, use and care, exhaust adapter, turntable ring, shelf, filters, glass tray and the small hardware bag. Do not remove the Styrofoam protecting the front of the oven. please note: Do Not Remove plastic plug protective cover until just before hanging the unit. Keep the unit at least 8 inches away from the  counter top edge to prevent dropping because of the heavy door
  2. Fold back all 4 carton flaps fully against carton sides. Then carefully roll the oven and carton over onto the top side. The oven should be resting in the Styrofoam.
  3. Pull the carton up and off the oven.
  4. Cut the middle of the outer protective plastic bag to remove the mounting plate
  5. Remove the screws from each end of the mounting plate. This plate will be used as the rear wall template and for mounting. Reinstall the screws into the holes where they were removed.

B. FINDING THE WALL STUDS

  1. Find the studs, using one of the following methods:
    A. Stud finder – a magnetic device which locates nails.
    B. Use a hammer to tap lightly across the mounting surface to find a solid sound.

  2. This will indicate a stud location. After locating the stud(s), find the center by probing the wall with a small nail to find the edges of the stud. Then place a mark halfway
    between the edges. The center of any adjacent studs should be 16 (40.6 cm) or 24 (61 cm) from this mark.

  3. Draw a line down the center of the studs.

THE MICROWAVE MUST BE CONNECTED TO AT LEAST ONE WALL STUD.

INSTALLATION INSTRUCTIONS FOR EXTERNAL EXHAUST DUCTING

NOTE: If you need to install ducts, note that the total duct length of 3 1 ⁄4″ x 10″ (8.2 x 25.4 cm) rectangular or 5″ (12.7 cm)diameter/6″ (15.2 cm) diameter round duct
should not exceed 140 equivalent feet (42.7 m).
Outside ventilation requires an EXTERNAL EXHAUST
DUCT. Read the following carefully.
NOTE: It is important that venting be installed using the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages. Also, make sure dampers swing freely and nothing is blocking the ducts.
Exhaust connection:
The exhaust adaptor has been designed to mate with a standard 3 1 ⁄4″ x 10″ (8.2 x 25.4 cm) rectangular duct.
If a round duct is required, a rectangular-to-round transition adaptor must be used. A 5″ (12.7cm)/ 6″ (15.2cm) diameter duct is acceptable to use.
Maximum duct length:
For satisfactory air movement, the total duct length of 31⁄4″ x 10″ (8.2 x 25.4 cm) rectangular or 5″ (12.7 cm) diameter/6″ (15.2 cm) diameter round duct should not exceed 140 equivalent feet (42.7 m).
Elbows, transitions, wall and roof caps, etc., present additional resistance to airflow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total duct length, add the equivalent lengths of all transitions and adaptors plus the length of all straight duct sections. The chart below shows you how to calculate total equivalent ductwork length using the approximate feet of equivalent length of some typical ducts.

This Rear Wall Template serves to position the bottom mounting plate and to locate the horizontal exhaust outlet.

  1. Use a level to check that the template is positioned accurately.

  2. Locate and mark at least one stud on the left or right side of the centerline.
    It is important to use at least one wood screw mounted firmly in a stud to support the weight of the microwave. Mark two additional, evenly spaced locations for the supplied toggle bolts.

  3. Drill holes in the marked locations. Where there is a stud, drill a 3/16″ hole for wood screws. For holes that do not line up with a stud, drill 5/8″ holes for toggle bolts.
    DO NOT INSTALL THE MOUNTING PLATE AT THIS TIME.

  4. Remove the template from the rear wall.

  5. Review the Installation Instruction book for your installation situation.

NOTE IT IS VERY IMPORTANT TO READ AND FOLLOW THE DIRECTIONS IN THE INSTALLATION INSTRUCTIONS BEFORE PROCEEDING WITH THIS TOP CABINETTEMPLATE. This template is used to locate the power cord clearance hole, cabinet mounting holes and the vertical exhaust cutout.

  1. Determine if your cabinet has a recessed area or a smooth, flat bottom. See Fig. 1. If smooth, tape template onto the bottom surface (Fig. 2). If it is recessed, cut the edges of the template to fit in the recessed bottom of the cabinet. It is important that the edges of the cabinets permit level installation of the oven.
    NOTE: On some cabinets a small bracket or glue block is used between the overhang and the underside of the cabinet bottom. Cut the template to fit around the bracket or glue block so that template will lie flat against the bottom of the cabinet. Tape the Top Cabinet Template to the underside of the top cabinet in the recessed area. Fig. 3. NOTE: Make sure the rear of the template touches the back wall (for smooth, flat bottom cabinets) or the back of the recess (for recessed bottom cabinets) after cutting the edges of the template.

  2. Drill 3/8 “diameter holes at A., B. &C. CA UTION: Wear safety goggles when drilling holes in the cabinet bottom.

  3. Cut out the 2 ” diameter hole at D . for power cord. If cabinets are metal, use the nylon grommet (see the Parts Included section in the Installation Instructions) to surround the opening to protect the cord.

  4. (FOR VERTICAL EXHAUST ONLY) Cut out shaded area E. through the cabinet bottom for Vertical (Outside) Exhaust location.

  5. Remove the top cabinet template.

  6. For recessed cabinets make 2 filler blocks out of scrap wood the size of the shaded areas F.& G. These filler blocks must have a thickness equal to the depth of the cabinet recess. Drill I 2 diameter holes in these blocks to line up with A.& C.. Place the blocks so that the holes in each block line up with the corresponding holes in the cabinet. The filler blocks should be at the same level as the bottom edge of the wall cabinet frame. Fig. 4.

  7. RETURN TO AND PROCEED WITH THE INSTALLATION INSTRUCTIONS.
