SAVE THESE INSTRUCTIONS FOR THE LOCAL ELECTRICAL INSPECTOR'S USE.
LEAVE THESE INSTRUCTIONS WITH THE APPLIANCE AFTER INSTALLATION IS
COMPLETE.
_ ARNING: Ifthe information in this manual is not followed exactly, fire or
shock my result causing property damage or personal injury.
Unpack oven, remove all tape and packaging material and examine the oven for any
damage such as dents, broken door latches or cracks in the door. Notify dealer
immediately if oven is damaged. Do not install if oven is damaged.
Destroy the packaging after unpacking the appliance. Never allow children to play
with packaging material.
Unit is heavy and requires at least two people or proper equipment to move.
Hidden surface may have sharp edges. Use caution when reaching behind or under
appliance.
_ AUTION: For general ventilating use only. Do not use to exhausthazardous or explosive materials and vapours.
This appliance must be properly grounded. Grounding reduces risk of electric shock
by providing an escape wire for the electric current if an electrical short occurs. This
oven is equipped with a cord having a grounding wire with a grounding plug. The
plug must be plugged into an outlet that is properly installed and grounded.
_ ARNING: Improper use of the grounding can result in a risk of electric
shock.
Consult a qualified electrician or servicer if grounding instructions are not completely
understood, or if doubt exists as to whether the oven is properly grounded.
Do not use an extension cord. If the product power cord is too short, have a
qualified electrician install a three-slot receptacle. This oven should be plugged into
a separate 60 Hertz circuit with the electrical rating as shown in specifications table.
When the oven is on a circuit with other equipment, an increase in cooking times
may be required and fuses can be blown.
Microwave operates on standard household current, 110-120 V.

Important Safety Instructions
READ AND SAVE THESE INSTRUCTIONS
Electrical Requirements ÷ a three prong grounded outlet
÷ 120 V, 60 Hz, AC only
÷ 15 Amp electrical supply with a fuse or a circiut breaker
÷ 1.6 kilowatt
This product must be connected to a supply circiut of the proper voltage and
frequency. Wire size must conform to the requirements of the National Electric Code
or the prevailing local code for this rating. The power supply cord and plug should
be brought to a separate 15- to 20-amp branch circiut single grounded outlet. The
outlet box should be located in the cabinet above the microwave oven. The outlet
box and supply circiut should be installed by a qualified electrician and conform to
the National Electrical Code or the prevailing local code.
The voltage used must be the same as specified on this microwave oven. Using a
higher voltage is dangerous and may result in a fire or oven damage. Using a lower
voltage will cause slow cooking. The dealer is not responsible for any damages
resulting from the use of the oven with any voltage other than specified.
Location requirements Check the opening where the microwave oven will be installed. The location must
provide:
÷ Minimum installation dimensions (See Installation Dimensions illustration)
÷ Minimum one 2" x 4" (50.8 x 101.6 mm) wood wall stud and minimum 3/8" (9.5
mm) thickness drywall or plaster/lath within cabinet opening.
÷ Support for weight of 150 Ibs (68 kg), which includes microwave oven and items
placed inside the microwave oven and upper cabinet.
÷ Grounded electrical outlet inside upper cabinet. (See Electrical Requirements)
section.
Notes:
If installing the microwave oven near a left sidewall, make sure there is at least 7"
(178 mm) of clearance between the wall and the microwave oven, so that the
door can open fully.
Some cabinet and building materials are not designed to withstand the heat
produced by the microwave oven for cooking. Check with your builder or cabinet
supplier to make sure that the materials used will not discolor, delaminate or
sustain other damages.
Ground continuity check 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 ifthe outlet box does not meet Electrical Requirements, a
qualified electrician should be employed to correct any deficiencies.

Installer show the owner the location of the circuit breaker or fuse. Mark it for easy
reference.
Do not, under any circumstances, cut or remove the ground prong.It must be
plugged into a matching grounding type receptacle to aviod electrical shock. Ifthere
is any doubt as to wether the wall receptacle is properly grounded, the customer
should have it checked by a qualified electrician. Do not use an extension cord.
_ CAUTION: For personal safety, this product cannot be installed in cabinetarrangements such as an island or a peninsula. It must be mounted to both

Installation procedure
Removing the mounting
plate Note: To avoid possible damage to the work surface or to the bottom of the
appliance, cover the worksurface.
1. Remove any remaining contents from the microwave oven cavity.
2. Remove the screws from the mounting plate.
This plate will be used as the rear wall template and for mounting.
Finding the wall studs
3. Reinstall the screws into the holes where they were removed.
Note: To avoid damage to the microwave oven, do not grip or use the door or door
handle while the microwave oven is being handled.
Note: The microwave must be connected to at least one wall stud. If no wall studs
exist within the cabinet opening, do not install the microwave oven.
1. Locate the edges of the wall studs within the cabinet opening by using:
÷ a stud finder or
÷ a hammer (tapping lightly across the mounting surface to find a solid sound).
2. Place a mark halfway between the edges and draw a line down the center of the
studs (See possible wall studs configuration)
Possible wall stud configurations
These depictions show examples of preferred installation configurations with the
mounting plate.
Note: Care must be taken when drilling holes. Electrical wires may be concealed
behind the wall covering and contact with them could result in electrical shock.

No wall studs at corner holes
Wall stud at one corner hole
Note: If wall stud is within 61A"(159 mm) of the vertical centerline, only Room
Venting (recirculation) or Roof Venting installations can be done.

Attaching the mounting plate to the wall
Aligning the mounting plate _ CAUTION: Wear gloves to avoid cutting fingers on sharp edges.
Note: Make sure the cabinet bottom is level.
1. Draw a vertical line on the wall at the center of the cabinet space.
2. Use the mounting plate as a template and place it on the wall, making sure that
the tabs are touching the bottom of the cabinet (Figure 1) or the level line
(Figure 2).
3. Line up the notch and centerline of the mounting plate to the centerline on the
wall.
4. While holding the mounting plate, draw circles on the wall at holes A, B, C
and D.
Note: If neither A, B, C nor D is in a stud, find a stud somewhere in the bottom area
of the mounting plate and draw a fith 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.

Prepare rear wall
4. Drill %" (9,5 mm) holes at "A", "B" and "C"
_ CAUTION: Wear safety goggles when drilling holes in the cabinet bottom.
5. Cut out the 2" (50,8 mm) hole at "D". This hole is for the power supply cord.
Note: If the cabinet is metal, use the nylon grommet around the opening to protect
the cord.
For wall venting installation you need to cut out an opening on the rear wall.
_ AUTION: If exhaust adaptor is positioned outside considerrecommended dimensions, otherwise grease-laden air will discharge into
house structure.
1. Mark the centerline (See Attaching the mounting plate to the wall) % (10 mm)
down from the top of the mounting plate.
2. Using measuring tape, measure out 6" (152 mm) on both sides of the centerline,
and mark.
3. Measure down 4" (102 mm) from the mark made in Step 1, and mark.
4. Using a straight edge, draw the 2 horizontal level lines through the marks made in
Steps 1 and 3.
5. Draw the 2 vertical plumb lines down from the marks made in Step 2. to
complete the 12" x 4" (304 x 102 mm) rectangle. This is the venting cutout area.
The 12" x 4" (305 x 102 mm) cutout area must align with the wall damper vent
(where the damper assembly will be installed) on the back of the microwave oven.
Note: Cutout must be free of any obstructions so that the vent fits properly, and the
damper hinge opens fully and swings freely.
