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.
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.
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
• Never allow anyone to climb, sit, stand or hang on the oven door. Injury might result from contact with
hot food or the oven itself.
• Do not line the oven walls, racks, bottom, or any other part of the oven with aluminum foil or any other
material. Doing so will disrupt heat distribution, produce poor baking results and cause permanent
damage to the oven interior (aluminum foil will melt to the interior surface of the oven).
• Do not use aluminum foil or any other material to line the oven bottom. Improper installation of oven
liners may result in a risk of electric shock or fire.
• Make sure your appliance is properly installed and grounded by a qualified installer, according to the
installation instructions. Any adjustment and service should be performed only by qualified installers or
service technicians.
• Be certain that all packing materials are removed from the appliance before operating. Keep plastic,
clothes, paper, and other flammable materials away from parts of the appliance that may become hot.
• The electrical power must be shut off while the electrical connections are being made.
• Improper connection of aluminum house wiring to copper leads can result in an electrical hazard or fire.
Use only connectors designed for joining copper to aluminum and follow the manufacturer’s
recommended procedure closely.
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.

5IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
Operation
• DO NOT TOUCH HEATING ELEMENTS OR INTERIOR SURFACES OF OVEN. Heating elements may be hot
even though they are dark in color. Interior surfaces of an oven become hot enough to cause burns.
During and after use, do not touch or let clothing or other flammable materials contact heating elements
or interior surfaces of oven until they have had sufficient time to cool. Other surfaces, such as oven vent
openings and surfaces near these openings, oven doors, and windows of oven doors, also get hot and
may cause burns if not allowed to cool.
• Use care when opening door. The hot air and steam that escape can cause burns to hands, face and
eyes. Let hot air or steam escape from the oven before removing or replacing food in the oven.
• Do not use plastic to cover food. Use foil or oven-safe lids only.
• Never attempt to dry a pet in the oven.
• Never use your appliance for warming or heating the room.
• Always use pot holders or oven mitts when removing food from an oven or cooktop. Cookware will be
hot. Use only dry pot holders. Moist or damp pot holders on hot surfaces may result in burns from
steam. Do not let the pot holder touch hot heating elements. Do not use a towel or other bulky cloth to
remove food.
• Do not heat unopened food containers. Pressure in the containers may cause them to burst which may
result in injury.
• Do not allow aluminum foil or the temperature probe to contact heating elements.
• Do not touch the oven racks while they are hot.
• Only arrange oven racks when the oven is cool. If a rack must be moved while the oven is hot, do not let
the pot holder contact the hot heating element in the oven.
• Pull the oven rack to the stop-lock position when loading and unloading food from the oven. This helps
prevent burns caused by touching hot surfaces of the door and oven walls.
• Do not use the oven if a heating element develops a glowing spot during use or shows other signs of
damage. A glowing spot indicates the heating element may fail and present a potential burn, fire, or
shock hazard. Turn the oven off immediately and have the heating element replaced by a qualified
service technician.
• Do not leave children alone or unsupervised near the appliance when it is in use or is still hot. Children
should never be allowed to sit or stand on any part of the appliance as they could be injured or burned.
• DO NOT block the oven vent during operation. This can damage the electric parts of the oven. Air must
be able to move freely. The bottom vent trim should be properly assembled on the front bottom of oven
before installing the oven door.
• Do not put large, heavy items such as whole turkeys on the open oven door.
• Take care when the door is open to avoid injury.
• If the door or door seals are damaged, the oven must not be operated until it has been repaired by a
competent person.
• Do not allow children to crawl into the oven.
• Do not put your hand under the controller or between the door and bottom vent trim during operation.
The outside of the oven can become very hot to the touch.
Maintenance
• Do not store items of interest to children on the back guard or in cabinets above a cooking appliance.
Children climbing on the oven to reach items could be seriously injured.
• Let hot cookware and utensils cool in a safe place, out of reach of small children.
• If the door glass, surface, or oven heating unit of the appliance are damaged, discontinue use of the
appliance and call for service.
• Always disconnect power from the appliance before servicing.

6IMPORTANT SAFETY INSTRUCTIONS
• Before replacing the oven light, switch off the electrical power to the oven at the main fuse or circuit
breaker panel.
• Never pour cold water over a hot oven for cleaning purposes.
• Oversized food or oversized metal utensils should not be inserted in a microwave/toaster oven as they
may create a fire or risk of electric shock.
• Do not clean with metal scouring pads. Pieces can burn off the pad and touch electrical parts causing a
risk of electric shock.
• Do not store any materials, other than manufacturer’s recommended accessories, in this oven when not
in use.
• Do not cover racks or any other part of the oven with metal foil. This will cause overheating of the oven.
• If the self-cleaning mode malfunction light goes on, or if the audible signal sounds, turn off or
disconnect the appliance from the power supply and have it serviced by a qualified technician.
• If the oven is heavily soiled with oil, self-clean the oven before using the oven again. The oil could cause
a fire.
• If there is a fire in the oven during self-clean, turn the oven off and wait for the fire to go out. Do not
force the door open. Introduction of fresh air at self-clean temperatures may lead to a burst of flame
from the oven. Failure to follow this instruction may result in severe burns.
• If your oven is dropped or damaged, have it thoroughly checked by a qualified service technician before
using it.
Risk of Fire and Flammable Materials
• Do not store or use flammable material in or near the oven. Flammable materials include paper, plastic,
pot holders, linens, wall coverings, curtains, and gasoline or other flammable vapors and liquids such as
grease or cooking oil. These materials can be ignited when the oven is in use.
• Use extreme caution when moving or disposing of hot grease.
• Wear proper apparel. Do not wear loose-fitting or hanging garments, which may ignite if they contact
hot surfaces, and cause severe burns.
• Do not use the oven for drying clothes. Only use the oven for its intended purpose.
• If cabinet storage is provided directly above the oven, use it to store items that are not frequently used
and can be safely stored in an area subjected to heat. Temperatures may be unsafe for volatile items
such as flammable liquids, cleaners or aerosol sprays.
• Do not use water on grease fires. Should an oven fire occur, leave the oven door closed and turn the
oven off. If the fire continues, throw baking soda on the fire or use a fire extinguisher. Do not put water
or flour on the fire. Flour may be explosive and water can spread a grease fire and cause personal injury.
CAUTION
CAUTION
• To reduce the risk of minor injury to persons, malfunction, or damage to the product or property when
using this product, follow basic precautions, including the following:
Operation
• Always heat fat slowly, and watch as it heats.
• If frying combinations of oils and fats, stir them together before heating.
• Use a deep fat thermometer, if possible, to prevent overheating fat beyond the smoking point.
• Use the least possible amount of fat for effective shallow or deep-fat frying. Filling the pan with too much
fat can cause spillovers when food is added.

7IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
SAVE THESE INSTRUCTIONS
• Accessible parts may become hot when the grill is in use.
• Do not place food or cookware on the bottom of the oven cavity. Doing so will cause permanent damage
to the oven bottom finish.
• When using cooking or roasting bags in the oven, follow the manufacturer’s directions.
• To protect against food-borne illnesses, cook meat and poultry thoroughly. The USDA has indicated the
following as safe minimum internal temperatures for consumption:
- Ground beef: 160 °F (71 ℃)
- Poultry: 165 °F (74 ℃)
- Beef, veal, pork, or lamb: 145 °F (68 ℃)
- Fish/seafood: 145 °F (68 ℃)
• Do not use this oven for commercial purposes. It is made for household use only.
• The door or the outer surface may get hot when the appliance is operating.
• Do not use this oven for purposes other than cooking.
• Use caution if opening the door when the oven is operating. Hot surfaces can cause serious burns.
Maintenance
• Do not repair or replace any part of the appliance unless specifically recommended in the manual. All
other servicing should be performed by a qualified technician.
• Do not use harsh, etching, abrasive cleaners or sharp metal scrapers to clean the oven door glass since
they can scratch the surface. Scratches may cause the glass to shatter.
• Make sure oven lights are cool before cleaning.
• Do not clean the door gasket. The door gasket is essential for a good seal. Care should be taken not to
rub, damage, or move the gasket.
• Never keep pet birds in the kitchen. The health of birds is extremely sensitive to the fumes released
during an oven self-clean cycle. Fumes may be harmful or fatal to birds. Move birds to a well-ventilated
room.
• Do not rinse trays and racks by placing them in water just after cooking. This may cause breakage or
damage.
• The oven should be cleaned regularly and any food deposits should be removed. Failure to maintain the
oven in a clean condition could lead to deterioration of the surface that could shorten the life of the
appliance and possibly result in a hazardous situation.
• Clean in the self-clean cycle only parts listed in this manual. Before self-cleaning the oven, remove the
broiler pan, all oven racks and any utensils or food from the oven.

16 OPERATION
NOTE
• Default cook mode times are without setting a cook time.
Operating the Oven
Before Using the Oven
NOTE
• Because the oven temperature cycles, an oven
thermometer placed in the oven cavity may not
show the same temperature that is set on the
oven.
• It is normal for the convection fan to run while
preheating during a regular bake cycle.
• The convection fan motor may run periodically
during a regular bake cycle.
• The heat turns off if the door is left open during
baking. If the door is left open for longer than 30
seconds during baking, the heat turns off. The
heat turns back on automatically once the door
is closed.
• Avoid opening the oven door more than
necessary during use. This helps the oven
maintain temperature, prevents unnecessary
heat loss, and saves on energy use.
Oven Vent
Areas near the vent may become hot during
operation and may cause burns. Avoid placing
plastics near the vent as heat may distort or melt
the plastic.
It is normal for steam to be visible when cooking
foods with high moisture content.
WARNING
• Do not block the vent opening at the bottom of
the oven.
Using Standard Oven Racks
The racks have a turned-up back edge that
prevents them from being pulled out of the oven
cavity.
CAUTION
• Replace oven racks before turning the oven on
to prevent burns.
• Do not cover the racks with aluminum foil, or
any other material, or place anything on the
bottom of the oven. Doing so will result in poor
baking and may damage the oven bottom.
• Do not place objects heavier than 33 lb (15 kg)
on the racks. Do not place heavy objects on the
corners of the racks. Doing so can damage the
racks.
Removing Racks
1 Pull the rack straight out until it stops.
2 Lift up the front of the rack and pull it out.
Replacing Racks
1 Place the end of the rack on the support.
2 Tilt the front end up and push the rack in.
Using Gliding Oven Racks
The optional gliding racks slide in and out on a
frame. This keeps heavy cookware level and
prevents it from sliding forward when the rack is
completely extended.
CAUTION
• Place oven racks in the desired location before
turning on the oven to avoid burns.
• Do not cover the racks with aluminum foil, or
any other material, or place anything on the
bottom of the oven. Doing so will result in poor
baking and may damage the oven bottom.
Installing Gliding Racks
1 Start with the rack in the closed position. Hold
the rack with one hand at the center front and
the other hand at the back right corner.

Tips for Convection Baking
• Use Convection Bake for faster and more even
multiple-rack cooking of pastries, cookies,
muffins, biscuits, and breads of all kinds.
• Bake cookies and biscuits on pans with no sides
or very low sides to allow heated air to circulate
around the food. Food baked on pans with a
dark finish will cook faster.
• When using Convection Bake with a single rack,
place oven rack in position C. If cooking on
multiple racks, place the oven racks in positions
Band D.
• Multiple oven rack cooking may slightly increase
cook times for some foods.
• Cakes, cookies and muffins have better results
when using multiple racks.
The Convection Roast feature is designed to give
optimum roasting performance. Convection Roast
combines cooking with the convection fan to roast
meats and poultry. The heated air circulates
around the food from all sides, sealing in juices
and flavors. Foods are crispy brown on the outside
while staying moist on the inside. Convection
roasting is especially good for large tender cuts of
meat, uncovered.
Tips for Convection Roasting
Use a broiler pan and grid (sold separately) when
preparing meats for convection roasting. The
broiler pan catches grease spills and the grid helps
prevent grease splatters.
1 Place the oven rack in position Aor B.
2 Place the grid ain the broiler pan b.
3 Place the broiler pan on the oven rack.
CAUTION
• Do not use a broiler pan without a grid.
• Do not cover the grid with aluminum foil.
• Position food (fat side up) on the grid.
Bake Mode
Bake is used to prepare foods such as pastries,
breads and casseroles.
The oven can be programmed to bake at any
temperature from 170 ℉(80 ℃) to 550 ℉(285 ℃).
The default temperature is 350 ℉(175 ℃).

To Stop Cooking
Press Upper CLEAR / OFF or Lower CLEAR / OFF.
NOTE
• It is normal for the convection fan to operate
periodically throughout a normal bake cycle in
the oven. This is to ensure even baking results.
Baking Tips
• For best results, food should be placed on a
single rack with at least 1” to 1 1/2” of air space
between the pans and oven walls.
• Baking time and temperature will vary
depending on the characteristics, size, and
shape of the baking pan used.
• Check for food doneness at the minimum recipe
time.
• Use metal bakeware (with or without a nonstick
finish), heatproof glass-ceramic, ceramic or
other bakeware recommended for oven use.
• Dark metal pans or nonstick coatings will cook
food faster with more browning. Insulated
bakeware will slightly lengthen the cooking time
for most foods.
• The oven bottom has a porcelain-enamel finish.
To make cleaning easier, protect the oven
bottom from excessive spillovers by placing a
cookie sheet on the rack below the rack you are
cooking on. This is particularly important when
baking a fruit pie or other foods with a high acid
content. Hot fruit fillings or other foods that are
highly acidic may cause pitting and damage to
the porcelain-enamel surface and should be
wiped up immediately.
Recommended Baking Guide
Rack and Pan Placement
Baking results will be better if baking pans are
centered in the oven as much as possible. If
cooking on multiple racks, place the oven racks in
the positions shown.
Multiple-rack cooking saves time and energy.
Whenever possible, cook foods requiring the same
cooking temperature together in one oven.
If baking with more than one pan, place the pans
so that each one has at least 1” to 1 ½” of air space
around them.

Baking Rack Guide
NOTE
• When baking cakes and cookies on multiple
racks, use the Convection Bake mode and place
racks in positions Band D.
Broil Mode
Setting the Oven to Broil
Broiling uses an intense, radiant heat to cook food.
Both the inner and outer broil elements heat
during full broiling. Only the inner broil element
heats during center broiling. The element(s) cycle
on and off at intervals to maintain the oven
temperature.
Keep the oven door closed while broiling. Let the
oven preheat for approximately 5 minutes before
cooking food.
CAUTION
• Do not use a broiler pan without a grid. Oil can
cause a grease fire.
• Do not cover the grid and broiler pan with
aluminum foil. Doing so will cause a fire.
• Always use a broiler pan and grid for excess fat
and grease drainage. This will help to reduce
splatter, smoke, and flare-ups.
• Should an oven fire occur, leave the oven door
closed and turn the oven off. If the fire
continues, throw baking soda on the fire or use a
fire extinguisher.
• DO NOT put water or flour on the fire. Flour may
be explosive and water can cause a grease fire to
spread and cause personal injury.
• When using your broiler, the temperature inside
the oven will be extremely high. Take care to
avoid possible burns by:
- Keeping the door closed when broiling
- Always wearing oven mitts when inserting or
removing food items
NOTE
• This appliance is designed for closed-door
broiling. Close the door to set the Broil function.
If the door is open, the Broil function cannot be
