READ ALL INSTRUCTIONS BEFORE USE
Safety Messages
Your safety and the safety of others are very important.
We have provided many important safety messages in this manual and on your appliance. Always read and
follow all safety messages.
WARNING
WARNING
• To reduce the risk of explosion, fire, death, electric shock, injury or scalding to persons when using this
product, follow basic precautions, including the following:
Installation
• This appliance should not be installed by anyone except properly qualified service personnel.
• You will need two people to install this appliance. It is heavy and could cause personal injury if not
handled properly.
• Avoid Electric 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
appliance. If you do not disconnect the power, you could get an electric shock.
• This appliance must be grounded.
If there is an electrical short circuit, grounding reduces the risk of electric shock by providing an escape
wire for the electric current. This appliance is equipped with a cord which includes a grounding wire with
a grounding plug.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill or injure you and others. All safety
messages will follow the safety alert symbol and either the word WARNING or CAUTION.
These words mean:
WARNING
You may be killed or seriously injured if you do not follow instructions.
CAUTION
You may be injured or cause damage to the product if you do not follow instructions.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and
tell you what may happen if the instructions are not followed.

a vertical, 2" x 4" wall stud.
• Do not mount the microwave oven to an island
or peninsula cabinet.
• Be sure the upper cabinet and rear wall
structures can support 150 lbs., plus the weight
of any items you place inside the oven or upper
cabinet.
• Locate the oven away from areas with strong
drafts, such as windows, doors, and strong
heating vents.
• The microwave oven has an inset handle on the
right side. To access the handle and allow the
door to swing open, install the product with
sufficient clearance on the sides. Do not block
the right side handle area by installing it against
a wall or cabinet.
(Model: MVEL213**, MVEL203**)
• Be sure you have enough space (minimum
vertical and horizontal clearance).
aMaximum 13": cabinet depth
bMinimum 30": cabinet opening width
cMinimum 30": clearance from bottom of
cabinet to cooking surface or countertop
before installation. (Use templates included
with installation instructions.)
dGrounded Outlet (inside upper cabinet)
ePower Supply Cord Hole
fMinimum 2": clearance from the top of the
range control panel to the bottom of

WARNING
• If you do not mount the oven as instructed, you
risk personal injury and/or property damage.
• If your range has cooktop controls in the front,
unplug the range before covering the cooktop to
prevent risk of fire and damage if the knobs are
accidentally activated while installing the OTR.

ENGLISH
NOTE
• If you have brick or masonry walls, you will need
special hardware and tools.
• The ductwork you need for the installation is not
included. All wall and roof caps must have a
back-draft damper (shown in Parts section).
• Wear proper gloves to protect your hands from
injury.
Installing the Microwave
Oven
Step 1: Prepare the Electrical
Connection
1 Locate the grounded electrical outlet bfor
this oven in the upper cabinet a.
NOTE
• The outlet should be on a circuit dedicated to the
microwave oven (120V, 60 Hz., AC only) with a 15
or 20 A fused electrical supply.
• Important: If you do not have the proper wall
outlet, you MUST have one installed by a
qualified electrician.
2 You will cut the hole cfor the power supply
cord later when you prepare the wall and
upper cabinet in Step 4.
NOTE
• Do not use an extension cord. Keep the power
cord dry and do not pinch or crush it.
WARNING
• Avoid electric shock. This appliance must be
grounded.
• Improper grounding could result in electric
shock or other personal injury.
Do not, under any circumstances, remove the
power supply cord grounding prong.
Step 2: Prepare the Venting System
WARNING
• This oven must be properly vented.
You may vent your ductwork in one of three ways.
Do not vent into a wall cavity, an attic, or an
unused area.
Roof Venting
The oven is located on an outside wall near the
roof: 3 1/4" x 10" duct dor minimum 6" diameter
round duct e.

venting or wall venting), be sure there is enough
clearance within the wall for the exhaust duct.
Room Venting
The oven is located on an inside wall of your
house.
aCabinet
bOven
When Installing Venting
• Keep the length of the ductwork and the number
of elbows to a minimum to ventilate your oven
efficiently. See examples in next section.
• Keep the size of the ductwork the same.
• Do not install two elbows together.
• Use duct tape to seal all joints in the duct system.
• Use caulking to seal the exterior wall or roof
opening around the cap.
• After installation, check the outside hood
opening and operation.
• For the outside hood opening and size refer to
the upper cabinet template or rear wall
template.
NOTE
• The ductwork you need for outside ventilation is
not included with your oven. See the standard
ductwork fittings.
Standard Ductwork Fittings
If the existing duct is round, you must use a
rectangular-to-round adapter, with a rectangular
3" extension duct installed between the damper
assembly and the adapter to prevent the exhaust
damper from sticking.
Duct Length
The total length of the duct system, including
straight duct, elbows, transitions, and wall or roof
caps must not exceed 140 feet.
For best performance, do not use more than three
90 degree elbows, and keep the length as short as
possible.
Below are the standard fittings and their
equivalent length in feet.
3 1/4" x 10" to 6" transition = 5 ft
3 1/4" x 10" roof cap = 24 ft
3 1/4" x 10" 90° elbow = 25 ft
90° elbow = 10 ft
3 1/4" x 10" wall cap = 40 ft
45° elbow = 5 ft

ENGLISH
To calculate the equivalent length of each duct
piece used, see the examples below.
Step 3: Prepare the Venting Blower
Your microwave oven is shipped with the blower
assembled for roof venting. You need to adjust the
blower if you want wall-venting or room-venting
installation.
WARNING
• Electric shock hazard! Unplug unit before
working on it.
• Do not pull or stretch the blower wiring. Pulling
and stretching the blower wiring could result in
electric shock.
• To avoid risk of property damage, unplug the
microwave oven or disconnect the power at the
source by removing the fuse or throwing the
circuit breaker.
• To avoid risk of personal injury, wear protective
gloves when handling the mounting plate.
Installation
1 Remove any shipping materials and parts
from inside the microwave oven. Set them
aside for later use.
2 Cover the countertop or cooktop with a thick,
protective covering to protect it from damage
and dirt. If your range has cooktop controls in
the front, unplug the range before covering
the cooktop to prevent risk of fire and
damage if the knobs are accidentally activated
while installing the OTR.
aBlanket, cardboard or other covering
NOTE
• If you have a free-standing range, disconnect it,
move it onto a piece of cardboard or hardboard
and pull it away from the wall, so that you can
get closer to the upper cabinet and back wall for
easier measuring and drilling.
3 Locate the exhaust adapter, grease filters and
hardware packet.
4 At this point, remove any adhesive tape (if
there is any), on the exhaust adapter, the
grease filters and the power supply cord.
Roof-Venting Installation
This oven is shipped assembled for roof-venting.
1 Insert the tabs on each side of the damper
into the holes at the inside rear of the
adapter. Attach the exhaust adapter ato the
blower plate bwith the two tapping screws
provided. Make sure that the damper c
swings freely.
