Equivalent lengths of duct pieces are based on actual tests and reflect requirement for good venting performance with any vent hood.Total Length =63 Ft.

NOTE: Align the exhaust with the space between the studs, or the wall should be prepared at the time it is constructed by leaving enough space between the wall studs to accommodate the exhaust.

Exhaust connection

The hood exhaust has been designed to mate with a standard 3 1/4"x10" rectangular duct. If a round duct is required, a rectangular-to-round transiting adaptor must be used. Do not use less than a 6" diameter duct.

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.

Maximum duct length

For satisfactory air movement, the total duct length of 3 1/4"x10" rectangular or 6" diameter round duct should not exceed 140 feet.

Elbows, Transitions, Wall and Roof caps

Several duct pieces may 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.

NOTES:

  • The space between the cabinets must be 24" wide and free of obstructions.
  • When installing the microwave beneath smooth, flat cabinets, be careful to follow the instructions for power cord clearance. Make sure to leave enough space for power cord clearance.
  • To vent your microwave to the outside, see the Hood Exhaust section for exhaust duct preparation instructions.

INSTALLATION INSTRUCTIONS

Placing the Mounting Plate

  1. Open the microwave box, and remove the microwave. It will be wrapped in a plastic bag.
  2. Remove the plastic bag, being careful to save the upper foam, where the mounting bracket is located.
  3. Remove the mounting bracket from the upper foam.

Finding your Wall Studs

NOTE: The microwave must be anchored to at least one wall stud.

Locating a wall stud can be done by using a magnetic stud-finder or tapping lightly across the mounting surface to find a solid sound. The location of the solid sound should be the location of the stud.

  1. Find the center of the stud by probing a small nail into the wall to find the edges of the stud.
  2. Place a mark halfway between the edges. The center of the adjacent stud should be 16" or 24" from this mark.
  3. Draw a line down the center of the wall studs.

Your cabinets may have decorative trim that interferes with the microwave installation. Remove the decorative trim to install the microwave properly and to make it level.

Use a level to make sure the cabinet bottom is level. If the cabinets have a front overhang only, with no back or side frame, the top line of the rear wall template must align below cabinet bottom by the same distance as the front overhang depth. This will keep the microwave level.

  1. Measure the inside depth of the front overhang.
  2. Draw a horizontal line on the back wall an equal distance below the cabinet bottom as the inside depth of the front overhang.
  3. For this type of installation with front overhang only, align top line of rear wall template with this horizontal line, not touching the cabinet bottom as described in step D.

Aligning the Top Line of your Rear Wall Template
REAR WALL TEMPLATE Centerlinenotches Center line Area E

CAUTION: Wear gloves when installing to prevent cutting your fingers on sharp edges.

  1. Using a tape measure, draw a vertical line on the wall at the center of the 24" wide space.
  2. Tape the rear wall template on the wall, aligning the center marks on the rear wall template with the center line on the cabinet.
  3. The location of the rear wall template will depend on what type of cabinet you are installing the microwave under. (See above examples.)
  4. After taping the rear wall template to the wall, draw circles at the A, B, and C holes (see above illustration).

NOTE: You must use all three mounting holes. It is recommended to use four mounting holes if there are 2 wall studs on the left and 2 wall studs on the right of the center line.

  1. Remove the rear wall template, and check the markings based on the actual mounting plate (centerline, hole A, B, and C).
  2. Drill holes on the circle marks for A, B, and C. Use a 3/16" bit for hole C (to mount into the wooden stud) and a 5/8" bit for A and B (to secure with a toggle bolt).

NOTE: Do not mount the plate yet.

  1. If the rear wall template is damaged or unusable, measure and mark the wall with the dimensions shown to the right:

Mount the Microwave

For easier installation and personal safety, we recommend that two people install this microwave oven.

CAUTION: Do not grip or use the handle during installation. Also, if filler blocks are not used, damage to the microwave case may occur from over tightening screws.

NOTES:

  • If your cabinet is metal, use the nylon grommet around the power cord hole to prevent the cutting of the cord.
    • We recommend using filler blocks if the cabinet front hangs below the cabinet bottom shelf.
  • When mounting the microwave oven, thread power cord through hole in bottom of top cabinet. Keep it tight throughout Step 1-3. Do not pinch the power cord or lift the oven by pulling cord.
