IMPORTANT SAFETY INSTRUCTIONS

This product requires a three-prong grounded outlet. The installer must perform a ground continuity check on the power outlet box before beginning the installation to insure that the outlet box is properly grounded. 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 house fuse or open circuit breaker before beginning 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 63-85 pound product, plus additional oven loads of up to 50 pounds or a total weight of 113-135 pounds.

CAUTION: For personal safety, this product cannot be installed in cabinet arrangements such as an island or a peninsula. It must be mounted to BOTH a top cabinet AND a wall.

NOTE: For easier installation and personal safety, it is recommended 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 3-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.

Where a standard two-prong wall receptacle is encountered, 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, 15 amps, and

1.58 kilowatts. 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 15 to 20 ampere branch circuit single grounded outlet. 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.

Insure proper ground exists before use

OUTSIDE TOP EXHAUST (EXAMPLE ONLY)

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

* 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.

NOTE: If you need to install ducts, note that the total duct length of 3

⁄4″ 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

⁄4″ 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

⁄4″ 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 approximate feet of equivalent length of some typical ducts.

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. 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″ 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.

Remove the installation instructions, filters, glass tray, and the small hardware bag. Do not remove the Styrofoam protecting the front of the oven.

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.

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.

If the cabinets have a front overhang only, with no back or side frame, install the mounting plate down the same distance as the front overhang depth. This will keep the microwave level.

Measure the inside depth of the front overhang.

Draw a horizontal line on the back wall an equal distance below the cabinet bottom as the inside depth of the front overhang.

For this type of installation with front overhang only, align the mounting tabs with this horizontal line, not touching the cabinet bottom as described in Step D.

ALIGNING THE WALL PLATE

Draw a vertical line on the wall at the center of the

36″ 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 touching the bottom of the

cabinet. Line up the notch and center line on the mounting plate to the center line on the wall.

While holding the mounting plate with one hand, draw circles on the wall at holes A, B, C and D (see illustration above/actual plate marked with arrows).

Four holes must be used for mounting.

NOTE: Holes C and D are inside area E. If neither

C nor D is in a stud, find a stud somewhere in area E and draw a fifth circle to line up with the stud. It is important to use at least one wood screw mounted

firmly in a stud to support the weight of the microwave.

Set the mounting plate aside.

Drill holes on the circles. If there is a stud, drill a

⁄16″

hole for wood screws. For holes that don’t line up with a stud, drill a

⁄8″ hole for toggle bolts.

NOTE: DO NOT MOUNT THE PLATE AT THIS TIME.
