Avoid Electrical Shock!
• Before you drill into the wall, note where electrical
outlets are and where electrical wires might be
concealed behind the wall. YOU COULD GET AN
ELECTRIC SHOCK if you contact electrical wires
with your drill bit.
• Locate and disconnect the power to any electrical
circuits that could be affected by installing this oven.
IF YOU DO NOT DISCONNECT THE POWER,
YOU COULD GET AN ELECTRIC SHOCK.
Electrical rating of this oven: 120V AC 60Hz.
• 13 A / 1500 W (Microwave oven, Cooktop Lamps,
Ventilation Fan)
• You need a DEDICATED 120VAC / 60Hz / 20A, fused
electrical supply (located in the cabinet above the
microwave as close as possible to the microwave)
serving only the microwave.
WARNING
!
To avoid risk of electrical shock, personal injury or
death; do not use the grounding plug improperly.
• Check with a qualified electrician if you are not sure
whether the oven is properly grounded or if you do not
completely understand the grounding instructions.
• Do not use a fuse in the neutral or grounding circuit.
• Save these instructions for the local electrical
inspector’s use.
• This appliance MUST be grounded!
• If there is an electrical short circuit, grounding
reduces the risk of electrical shock by providing an
escape wire for the electric current. This appliance
is equipped with a cord having a grounding wire with
a grounding plug.
• Place the plug into a properly installed and grounded
outlet.
• Do not use an extension cord.
• Keep the power cord dry and do not pinch or crush.
• Do not, under any circumstances, remove the power

Room Venting
Oven is located on an inside wall of house.
Room Venting
NOTE: Remember the following when installing venting.
• Keep length of ductwork and the number of
elbows to a minimum to ventilate oven
efficiently.
• Keep the size of the ductwork the same.
• Do not install two elbows together.
• Use duct tape to seal all joints in the ductwork
system.
• Use caulking to seal exterior wall or roof
opening around the cap.
Standard Fittings
NOTE: If existing ductwork is round, a rectangular-to-
round adapter must be used with a rectangular
3" extension duct installed between the damper
assembly and adapter to prevent the exhaust
damper from sticking.
Ductwork Length
The total length of the ductwork system, including
straight duct, elbows, transitions, and wall or roof cap
must not exceed the equivalent of 140 feet.
For best performance, do not use more than three 90°
elbows and keep the length as short as possible.

covering
NOTE: For easy access to wall and upper cabinet,
remove range from wall to allow easier
measuring and drilling.
Preparing Template Placement
1. Find and mark the vertical center line on the back
wall, using a tape measure and plumb line.
2. Find and mark placement of one or two points
indicating stud location on the wall.
• Measure and mark stud location within the area
marked Hon the wall template.
• If wall studs cannot be located, consult a local
building contractor.
WARNING
!
To avoid risk of property damage or personal injury,
do not attempt to install microwave oven if wall studs
cannot be located.
3. Align plumb line on wall with center line on the wall
template.
• Verify minimum width is 30" and the distance from
the top of wall template to the range or countertop
is at least 30".
4. Secure wall template to the wall.
• If cabinets are not level, adjust the wall template
to align with cabinet.
• Oven must hang level. If the front edge of the
cabinet is lower than the back edge, adjust wall
template to be level with the cabinet front.
Upper cabinet template

5. Measure the bottom of the upper cabinet frame. Trim
the edges A, B, and Con the upper cabinet
template, so template will fit on the bottom of the
upper cabinet. If upper cabinet has a recessed
frame, trim the template to fit inside the recessed
area. Align the centerline of the upper cabinet
template with the centerline on the wall template.
