from steam. Do not let potholder
touch hot heating elements. Do
not use a towel or other bulky
cloth.
• DO NOT TOUCH SURFACE UNITS
OR AREAS NEAR UNITS – Surface
units may be hot even though
they are dark in color. Areas
near surface units may become
hot enough to cause burns.
During and after use, do not
touch, or let clothing or other
flammable materials contact
surface units or areas near units
until they have had sufficient
time to cool. Among these areas
are the coil elements, the
cooktop, and surfaces facing the
cooktop.
• 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.

OPERATION
COOKTOP
BEFORE USING THE COOKTOP
Read all instructions before using.
WARNING
• Do not cook on a broken cooktop. If the cooktop is broken, cleaning
solutions and spillovers may penetrate the broken cooktop and create a
risk of electric shock. Contact a qualified technician immediately.
• Do not place or store items that can melt or catch fire on the glass
cooktop, even when it is not being used.
• Never leave surface units unattended at high heat settings. Boilovers
cause smoking and greasy spills that may catch on fire.
• Keep flammable items away from the cooktop.
• Turn off all controls when done cooking.
• Turn cookware handles inward and not extend over adjacent surface
units to reduce the risk of burns, ignition of flammable materials, and
spillage due to unintentional contact with the cookware.
• Always place the pan in the center of the surface unit you are cooking
on. Proper contact of cookware to heating element also will improve
efficiency.
• Clean cooktop with caution. If a wet sponge or cloth is used to wipe
spills on a hot cooking area, be careful to avoid steam burn. Some
cleaners can produce noxious fumes if applied to a hot surface.
24
CAUTION
• Never cook directly on the glass. Always use cookware.
• Do not use the glass cooktop surface as a cutting board.
• Do not slide metal or glass across the cooktop surface. Cookware with
rough or uneven bottoms can mark or scratch the cooktop surface.
• Do not place sealed containers on the cooktop.
• Do not place aluminum foil or plastic items such as salt and pepper
shakers, spoon holders, or plastic wrappings or any other material on
the range when it is in use.
• Do not turn surface units on before placing cookware.
• Always turn the surface units off before removing cookware.
• The surface element may appear to have cooled after it has been
turned off. The element may still be hot and touching the element
before it has cooled sufficiently can cause burns.
• Only certain types of glass, glass-ceramic, ceramic, earthenware, or
other glazed cookware are suitable for range-top service without
breaking due to the sudden change in temperature.
• Choose proper heating element size. For smaller pots and pans, use the
smaller heating elements. For larger pots and pans, use the larger
heating elements. Select pans that have flat bottoms large enough to
cover the heating elements. Using undersized pans exposes a portion of
the heating element to direct contact and may result in clothing
burning.
• Immediately clean spills on the cooking area to prevent a tough
cleaning chore later.
• Do not use a steel-wool pad or scrub pad or abrasive cleaning pads.
They can scratch the surface.

COS-ERD304K(-BK)
NOTE:
COOKING AREAS
The cooking areas on your range are identified by permanent circles on the
glass cooktop surface.
When a control is turned on, a glow can be seen through the glass cooktop
surface.
For the most efficient cooking, fit the pan size to the element size. Pans should
not extend more than 1/2" to 1" (1.3 cm to 2.5 cm) beyond the cooking area.
HOT SURFACE INDICATOR
The hot surface indicator light glows and indicates that the corresponding
cooktop element is still hot. When the hot surface indicator turns off, the glass
surface may still feel slightly hot to touch.
• The hot surface indicator light glows when the surface heating element
temperature reaches 113°F (45°C) and above.
• The hot surface indicator light remains on after the element is turned
off and until the surface has cooled to approximately 113°F (45°C).

In Case of Power Failure
The electric cooktop and oven cannot be used during a power outage.
If power is lost while a cooktop element is on, the cooktop element will turn
back on as soon as power is restored.
In the event of power loss, failure to turn all cooktop element knobs to the OFF
position may result in ignition of items on or near the cooktop, leading to
serious injury or death.
USING THE PROPER COOKWARE
The size and type of cookware will influence the settings needed for the best
cooking results. Cookware should have flat bottoms that make good contact
with the entire surface heating element. Using the correct cookware can
prevent many problems, such as uneven cooking or extended cooking times.
Cookware Recommendations
• Flat bottom and straight sides
• Heavy-gauge pans
• Pan sizes that match the amount of food to be prepared and the size of
the surface element
• Weight of handle does not tilt pan.
• Pan is well balanced
• Tight-fitting lids
• Flat bottom woks
NOTE:
• Do not use woks that have support rings. This type of wok will not heat
on glass surface elements.
• Do not use foil or foil-type containers. Foil may melt onto the glass. Do
not use the cooktop if metal has melted on it.
28
Choosing Cookware
The cookware material determines how evenly and quickly heat is transferred
from the surface element to the pan bottom.
Recommended
• Aluminum - Excellent heat conductor. Some types of food will cause
it to darken (anodized aluminum cookware resists staining and
pitting). If aluminum pans slide across the ceramic cooktop, they may
leave metal marks which will resemble scratches. Remove these
marks immediately. Because of its low melting point, thin weight
aluminum should not be used.
• Copper - Excellent heat conductor but discolors easily. May leave
metal marks on glass-ceramic (see Aluminum above). Do not let
these pots boil dry. Overheated metal can bond to glass cooktops.
An overheated copper bottom pot will leave a residue that will
permanently stain the cooktop if not removed immediately.
• Stainless Steel - Slow heat conductor with uneven cooking results. Is
durable, easy to clean and resists staining.
• Enamel (painted) on Cast Iron - Bottom of pan must be smooth
coated and smooth.
Not Recommended
• Enamel (painted) on Steel - Heating empty pans can cause
permanent damage to cooktop glass. The enamel can melt and
bond to the ceramic cooktop.
• Cast iron - A poor heat conductor, slow to absorb heat but retains
heat very well. Will scratch the glass surface. Not recommended
unless designed specifically for use on ceramic cooktops.
• Glass-ceramic - Slow heat conductor. Poor performance, and will
scratch the glass surface.
• Stoneware - Poor performance, and may scratch the glass surface.

OVEN
BEFORE USING THE OVEN
Read the instructions for each feature and cooking mode in this manual
carefully before using the oven.
CAUTION
• Do not use any type of foil or oven liner to cover the oven bottom. These
items can trap heat or melt, resulting in damage to the product and risk
of shock, smoke or fire. Damage from improper use of these items is not
covered by the product warranty.
• Foil may be used to catch spills by placing a sheet on a lower rack,
several inches below the food. Do not use more foil than necessary and
never entirely cover an oven rack with aluminum foil. Keep foil at least
1-1/2" (3.8 cm) from oven walls to prevent poor heat circulation.
• Do not cover the slotted grid of the 2-piece broiler pan with aluminum
foil. This will catch the grease and could cause fire.
• Do not use plastic wrap or wax paper in the oven.
• Do not place food, water, ice, or any dish or tray directly on the oven
floor, as this will irreversibly damage the enamel surface.
• Do not block, touch or place items around the oven vent during
cooking. Your oven is vented through ducts at the center above the rear
cooktop. Do not block the oven vent when cooking to allow for proper
air flow.
• The oven and broiler cannot be used during a power outage. If the
oven is in use when a power failure occurs, the oven heating element
shuts off and cannot be used until power is restored. Once power is
restored, you will need to reset the oven (or Broil mode).
• As the oven heats up, the heated air in the oven may cause
condensation to appear on the oven door glass. These water drops are
harmless and will evaporate as the oven continues to heat up.
30
WARNING
FOOD POISONING HAZARD
• Do not let food sit in oven more than one hour before or after cooking.
Doing so can result in food poisoning or sickness.
• 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 finished cooking.
IMPORTANT: Clock must be set in order for the oven to work. Your model has
a digital display clock with 3 control buttons. See "Setting the Clock and Timer"
section.
NOTE:
• Because the oven temperature cycles, an oven thermometer placed in
the oven cavity may not show the same set temperature on the oven.
BEFORE USING THE OVEN FOR THE FIRST TIME
Start the oven in Bake mode at the highest available temperature setting.
Allow oven to run for 1 hour to remove any dust or impurities. There will be a
distinctive odor - this is normal. Ensure your kitchen is well ventilated during
this conditioning period.
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.
Do not block the vents (air openings) of the range. They provide the air inlet
and outlet that are necessary for the range to keep cool and operate properly
with correct combustion.
It is normal for steam to be visible when cooking foods with high moisture
content.
31
OVEN DOOR
To avoid oven door glass breakage:
CAUTION
USING OVEN RACKS
The racks have a turned-up back edge that prevents them from being pulled
out of the oven cavity.
• Do not close the oven door if the racks are not fully inserted into the oven
cavity or if bakeware extends past the front edge of an oven rack.
• Do not set objects on the glass surface of the oven door.
• Do not hit glass surfaces with bakeware or other objects.
• Do not wipe down glass surfaces until the oven has completely cooled.
Removing Racks
Replacing Racks
1. Pull the rack straight out until it stops.
2. Lift up the front of the rack and pull it
out.
• 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.
• Only arrange oven racks when the oven is cool.
1. Place the end of the rack on the support.
2. Tilt the front end up and push the rack in.
32
Broiling performs best with the food close to the broil heating element -
typically rack position #5 or #6.
NOTE:
PREHEATING
Preheating is generally desirable, although not absolutely necessary in all
circumstances.
Rack Positions
For best cooking results, adjust rack so
food is placed at the center of the
oven. For most foods this will be rack
position #3 or #4. For larger foods like
roasts and turkey, move the rack
position down to #2 or #1 to keep the
food centered in the oven.
When using multiple racks
simultaneously, try to space the food
out around the oven center (rack
positions #3 and #5 or #2 and #4 for
two racks).
• The higher the set temperature is, the longer it will take to preheat.
• When the oven has reached the set temperature, the oven indicator
light on the control panel will turn off temporarily.
• The actual oven temperature will go slightly higher than the set
temperature during preheat to offset the heat lost when the oven door
is opened to place the food in oven. This ensures the cooking will begin
at the proper temperature.
Some foods are more robust and may have acceptable results without
preheating. These foods include large pieces of meat (whole roasts, hams, or
poultry) where the total cooking time is much longer than the time required to
preheat. These foods also include frozen potato products and frozen
processed dinners that, by their nature and design, are more robust to baking
variations. More delicate foods, such breads (including cakes, cookies,
pastries, and pizzas), desserts, soufflés, etc. will likely not have acceptable
results without proper preheating.

41
TIPS AND TECHNIQUES
BAKE
Baking is cooking with heated air. The lower element in the oven is used to
heat the air but no fan is used to circulate the heat.
Follow the recipe or convenience food directions for baking temperature, time
and rack position. Baking time will vary with the temperature of ingredients
and the size, shape and finish of the baking utensil.
• For best results, bake food on a single rack with at least 1" - 1½" (2.5 - 3
cm) space between utensils and oven walls.
• Use one rack when selecting the bake mode.
• Check for doneness at the minimum time.
• Use metal bakeware (with or without a non-stick finish), heatproof glass,
glass-ceramic, pottery or other utensils suitable for the oven.
• When using heatproof glass, reduce temperature by 25°F (15°C) from
recommended temperature.
• Use baking sheets with or without sides or jelly roll pans.
• Dark metal pans or nonstick coatings will cook faster with more browning.
Insulated bakeware will slightly lengthen the cooking time for most foods.
• Do not use aluminum foil or disposable aluminum trays to line any part of
the oven. Foil is an excellent heat insulator and heat will be trapped
beneath it. This will alter the cooking performance and can damage the
finish of the oven.
• Avoid using the opened door as a shelf to place pans.
• See Troubleshooting for tips on solving Oven Problems.

CONVECTION BAKE
Convection Bake uses heat from the lower heating element and air movement
from the convection fan to enhance cooking efficiency and evenness across
multiple racks. Reduce recipe baking temperatures by 25°F (15°C).
• For best results, foods should be cooked uncovered, in low-sided pans to
take advantage of the forced air circulation. Use shiny aluminum pans for
best results unless otherwise specified.
• Heatproof glass or ceramic can be used. Reduce temperature by another
25°F (15°C) when using heatproof glass dishes for a total reduction of
50°F (30°C).
• Dark metal pans may be used. Note that food may brown faster when
using dark metal bake ware.
• The number of racks used is determined by the height of the food to be
cooked.
• Baked items, for the most part, cook extremely well in convection. Don’t
try to convert recipes such as custards, quiches, pumpkin pie, or
cheesecakes, which do not benefit from the convection-heating process.
Use the regular Bake mode for these foods.
• Multiple rack cooking for oven meals is
done on rack positions 1, 2, 3, 4, 5, and
6. All six racks can be used for cookies,
biscuits and appetizers.
- 2 Rack baking: Use positions 1 and
3 or 2 and 4.
- 3 rack baking: Use positions 2, 3,
and 4 or 1, 3, and 5.
- When baking four cake layers at
the same time, stagger pans so
that one pan is not directly above
another. For best results, place
cakes on front of upper rack and
back of lower rack (See graphic at
right). Allow 1" - 1 ½" (2.5 - 3cm) air
space around pans.
• Converting your own recipe can be easy. Choose a recipe that will work
well in convection.
• Reduce the temperature and cooking time if necessary. It may take some
trial and error to achieve a perfect result. Keep track of your technique for
the next time you want to prepare the recipe using convection.
• See Troubleshooting for tips to Solving Baking and Roasting Problems.

CONVECTION ROAST
The Convection Roast mode uses heat from both upper and lower elements
and hot air movement from the convection fan to enhance cooking efficiency
and evenness across multiple racks. Heated air circulates around the food
from all sides, sealing in juices and flavors.
• Use the 2-piece broil pan, and roast in a low-sided, uncovered pan.
• When roasting whole chickens or turkey, tuck wings behind back and
loosely tie legs with kitchen string.
• Use a meat thermometer to determine the internal doneness.
• Double-check the internal temperature of meat or poultry by inserting
meat thermometer into another position.
• Large food item may need specific areas to be covered with foil (and pan
roasted) during part of the roasting to prevent over-browning.
• The minimum safe temperature for stuffing in poultry is 165°F (75°C).
• After removing the item from the oven, cover loosely with foil for 10 to 15
minutes before carving if necessary to increase the final foodstuff
temperature by 5°F to 10°F (3°C to 6°C).

RANGE CARE AND MAINTENANCE
CLEANING
IMPORTANT: Before cleaning, make sure all controls are off and the oven and
cooktop are cool. Always follow label instructions on cleaning products. Soap,
water and a soft cloth or sponge are suggested first unless otherwise noted.
Do not use abrasive cleaning products.
NOTE:
• Do not clean the oven door gasket. The material of the gasket cannot
withstand abrasion. It is essential for the gasket to remain intact. If you
notice it becoming worn or frayed, replace it.
• Re-engage the anti-t
ip bracket if range is moved.
GLASS-CERAMIC COOKTOP
• Before using the cooktop for the first time, clean it with a ceramic cooktop
cleaner. This helps protect the top and makes cleanup easier.
• Regular use of ceramic cooktop cleaner will help keep the cooktop
