If not properly grounded, or if the outlet box does not meet electrical requirements noted (under ELECTRICAL REQUIREMENTS), a qualified electrician should be employed to correct any deficiencies.

CAUTION: For personal safety, remove the house fuse or open the circuit breaker before beginning the installation to avoid severe or fatal shock injury.

CAUTION: For personal safety, the mounting surface must be capable of supporting the cabinet load in addition to the added weight of this 69 pound product, plus additional oven loads of up to 50 pounds or a total weight of 109 pounds.
CAUTION: For personal safety, do not install this product in cabinetry configured as an island or a peninsula. The microwave oven must be mounted to BOTH a top cabinet AND a wall.
NOTE: For easier installation and personal safety, we recommend that two people install this product.
IMPORTANT – PLEASE READ CAREFULLY. FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED TO AVOID SEVERE OR FATAL SHOCK.

The power cord of this appliance is equipped with a three-prong (grounding) plug which mates with a standard three-prong (grounding) wall receptacle to minimize the possibility of electric shock hazard from this appliance.

You should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded. If you have a standard two-prong wall receptacle, it is very important to have it replaced with a properly grounded three-prong wall receptacle, installed by a qualified electrician. DO NOT, UNDER ANY CIRCUMSTANCES, CUT, DEFORM OR REMOVE ANY OF THE PRONGS FROM THE POWER CORD. DO NOT USE WITH AN EXTENSION CORD.

ELECTRICAL REQUIREMENTS
Product rating is 120 volts AC, 60 Hertz. This product must be connected to a supply circuit of the proper voltage and frequency. Wire size must conform to the requirements of the National Electrical Code or the prevailing local code for this kilowatt rating. The power supply cord and plug should be brought to a separate branch circuit single grounded outlet of at least 15 A and max of 20 A. 20 A is recommended for multifamily buildings. The outlet box should be located in the cabinet above the microwave oven. The outlet box and supply circuit should be installed by a qualified electrician and conform to the National Electrical Code or the prevailing local code.

HOOD EXHAUST

NOTE: Read these next two pages only if you plan to vent your exhaust to the outside. If you plan to recirculate the air back into the room, proceed to page 11.

OUTSIDE TOP EXHAUST (EXAMPLE ONLY)
The following chart contains an example of one possible ductwork installation .

• IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have to be cut to fit, using the tin snips, in order to allow free movement of the damper.

OUTSIDE BACK EXHAUST (EXAMPLE ONLY)
The following chart contains an example of one possible ductwork installation .

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

NOTE: If you need to install ducts, note that the total duct length of 3 ¼” x 10″ rectangular or 6″ diameter round duct should not exceed 140 equivalent feet.
Outside ventilation requires a HOOD 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 hood exhaust has been designed to mate with a standard 3 ¼” x 10″ rectangular duct. If a round duct is required, a rectangular-to-round transition adaptor must be used. Do not use less than a 6″ diameter duct.

Maximum duct length:
For satisfactory air movement, the total duct length of 3 ¼” x 10″ rectangular or 6″ diameter round duct should not exceed 140 equivalent feet.

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 equivalent length in feet of some typical ducts.

IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have to be cut to fit, using tin snips, to allow free movement of the damper. Equivalent lengths of duct pieces are based on actual tests and reflect the requirements for good venting performance with any vent hood.

Step-by-step installation guide

PLACEMENT OF THE MOUNTING PLATE

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

1. Remove the installation instructions, Exhaust adaptor, filters, glass tray, and the small hardware bag. Do not remove the Styrofoam protecting the front of the oven.
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. Remove and properly discard plastic bags.
5. Remove the 2 screws from the mounting plate. This plate will be used as the rear wall template and for mounting.  

NOTE: Retain the two screws. You will need to re-insert the screws in their original locations after you have removed the mounting plate.

• B. FINDING THE WALL STUDS

  • Find the studs using one of the following methods:
  • A. With a stud finder – a magnetic device which locates nails. OR
  • B. Use a hammer to tap lightly across the mounting surface until you hear a solid sound. This will indicate a stud location.
  • After locating the stud(s), locate the stud’s 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″ or 24″ from this mark.
  • Draw a line down the center of the studs.
    THE MICROWAVE MUST BE CONNECTED TO AT LEAST ONE WALL STUD.

• C. DETERMINING WALL PLATE LOCATION UNDER YOUR CABINET
  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.
  THE MICROWAVE MUST BE LEVEL.
  Use a level to make sure the cabinet bottom is level

• D. ALIGNING THE WALL PLATE
  CAUTION: Wear gloves to avoid cutting fingers on sharp edges.

1. Draw a horizontal line on the wall at the bottom of the “Rear Wall Template”.
2. Drill ⅝” holes for toggle bolts in 3 locations (Hole A, Hole B, Hole C) as shown in the illustration above. If the location of a hole lines up with a stud, drill a 3/16″ hole for a wood screw. You cannot use a toggle bolt to attach the wall plate to a stud.  

NOTE: DO NOT MOUNT THE PLATE AT THIS TIME.

3. Holes A, B and C are inside area E. If none of these holes line up with a stud, find a stud in area E that lines up with a hole circle in Area E, and then drill a 3/16″ hole into it for a wood screw. You must have at least one wood screw mounted firmly into a stud to support the weight of the microwave. Set the mounting plate aside.
