SAFETY PRECAUTIONS
• Be certain your appliance is properly installed
and grounded by a qualified technician.
• Do not repair or replace any part of the
appliance unless specifically recommended in
the manual.
• All other servicing should be referred to a
qualified technician.
• Always disconnect power to appliance before
servicing by unplugging, removing the fuse or
switching off the circuit breaker.
• 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 of the
appliance may become hot enough to cause
burns. Among these surfaces are oven vent
openings and surfaces near these openings,
oven doors, and windows of oven doors.
• Use Care When Opening Door.
Let hot air or steam escape before you remove
or replace food in the oven
• Do Not Heat Unopened Food Containers.
Build-up of pressure may cause container to
burst and result in injury.
• Keep Oven Vent
Ducts Unobstructed.
The oven vent could
become hot during
oven use. Never block
this vent and never
place plastic or heat-
sensitive items on or
near the vent.
NOTE:
For proper operation vent trim must be installed.
• Be certain all packing materials are removed
from the appliance before operating.
Keep plastics, clothes, and paper away from
parts of the appliance that may become hot.
• DO NOT force the door open.
This can damage the automatic door locking
system. Use care when opening the oven door
after the self-cleaning cycle. Stand to the side of
the oven when opening the door to allow hot air
or steam to escape. The oven may still be
VERY HOT.
• DO NOT use a steel-wool pad.
It will SCRATCH the surface.
• DO NOT use harsh etching, abrasive
cleaners or sharp metal scrapers to clean
the oven door glass since they can scratch
the surface.
It may result in shattering of the glass.
•
Be careful when removing and lifting the door.
• DO NOT lift the door by the handle.
The door is very heavy.
• DO NOT step or sit on oven door.
Be sure to follow proper installation instructions.
ELECTRICAL SAFETY
• Protective Liners. Do not use aluminum foil or
any other material to line the oven bottoms.
Improper installation of these liners may result
in a risk of electric shock or fire.
• Do Not allow aluminum foil or meat probe to
contact heating elements.
Metal bottom

WARNING
• DO NOT place aluminum foil directly
on the oven bottom.

GENERAL
READ ALL INSTR
READ ALL INSTRUCTIONS BEFORE USE UCTIONS BEFORE USE
• Before replacing your oven light bulb, switch
off the electrical power to the oven at the
main fuse or circuit breaker panel.
Failure to do so can result in severe personal
injury, death, or electrical shock.
• 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.)
SAFETY DURING USE
• Oven Racks. Always place oven racks in
desired position while oven is cool.
• Always use pot holders or oven mitts when
removing food from the oven.
You can be burned because cookware and
plates will be hot.
• Use caution with the TIMED BAKE or
DELAYED TIMED BAKE features. Use the
automatic timer when cooking cured or
frozen meats and most fruits and
vegetables. Foods that can easily spoil,
such as milk, eggs, fish, meat or poultry,
should be chilled in the refrigerator first.
Even when chilled, they should not stand in
the oven for more than 1 hour before
cooking begins, and should be removed
promptly when cooking is completed.
Eating spoiled food can result in sickness from
food poisoning.
• 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.
• DO NOT use the broiler pan without the grid.
DO NOT cover the grid with aluminum foil.
CHILD SAFETY
WARNING
• Children should be kept away
from the oven.
• Accessory parts will become hot
when the broiler is in use.
CAUTION
• Children should not be left alone
or unattended in area where
appliance is in use. Children
should never be allowed to sit or
stand on any part of the
appliance.
CAUTION
• DO NOT leave small children
unattended near the appliance.
During the self-cleaning cycle, the
outside of the oven can become very hot
to the touch.

READ ALL INSTRUCTIONS BEFORE USE UCTIONS BEFORE USE
SAFETY WHEN CLEANING
• Do Not Clean Door Gasket. The door gasket is
essential for a good seal. Care should be taken
not to rub, damage, or move the gasket.
• Do Not Use Oven Cleaners. No commercial
oven cleaner or oven liner protective coating of
any kind should be used in or around any part
of the oven.
• Before self cleaning the oven. Remove broiler
pan, all oven racks, meat probe and any other
utensils from the oven cavity.
• 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 well-ventilated room.
• Important Instruction. In the event the self
clean error code Fis displayed, and error
melody sounds, the oven is malfunctioning in
the self clean mode. Switch off the electrical
power to the main fuse or breaker and have
serviced by a qualified technician.
• Make sure oven lights are cool before
cleaning.
• 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 metal
bottom trim (vent) should be properly
assembled on the front bottom of oven before
installing the oven door.

GENERAL INFORMATION TION
Rating Label
Model numbers are recorded on the rating label.
Rating label is located on the lower left bottom
area of the controller. It can be seen by opening
the door. Before ordering parts, write down the
correct model and serial number from rating
label. This avoids incorrect shipments and
delays. Please refer to parts reference material
when ordering replacement parts.
Functional Operation
Bake Mode
Top and hidden bottom elements operate during
bake. Bake can be used to cook foods which are
normally baked. Oven must be preheated.
Convection fan and heater operates during the
Preheat cycle of Bake mode.
Broil Mode
Top element operates during broil. Broil can be
used to cook foods which are normally broiled.
Preheating is not required when using broil. All
foods should be turned at least once except fish,
which does not need to be turned.
Convection Bake / Roast Mode
Upper element, lower element, Rear element and
fan operate during convection bake. Convection
bake should be used for cooking casseroles and
roasting meats. Oven should be preheated for
best results when using convection bake. Pans
do not need to be staggered. Cooks
approximately 25% quicker than bake.
Cooking Guide
Refer to the owners manual for recommendations
of times and temperatures. Times, rack position,
and temperatures may vary depending on
conditions and food type. For best results, always
check food at minimum time. When roasting,
choose rack position based on size of food item.
