Choosing a Location for Your Oven

You will use your oven frequently so plan its lo­cation for ease of use. The oven must be placed
on a countertop which is a minimum of 36 inches
from the floor. Allow at least 2 inches on the sides,
top and at the rear of the oven for air circulation.
Be sure to position oven so that the rear cannot
be touched inadvertently.

Built-in Kit

Your oven can be built into a cabinet or wall—not
near or above a heat source—using one of
Sharp’s Built-in Kits, Model RK-90S30. If your
dealer does not stock the kit, order directly by
call-ing 1-800-642-2122 to have it sent to your
address.

The kit includes ducts and finish trim strips and
easy-to-follow instructions for installation as well
as the location of the power supply.

GROUNDING INSTRUCTIONS

This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a
grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded in
accordance with the National Electrical Code and local codes and ordinances. In the event of an electri­cal short circuit, grounding reduces risk of electric shock by providing an escape wire for the electric
current.

WARNING – Improper use of the grounding plug can result in a risk of electric shock.
Electrical Requirements

The electrical requirements are a 240 volt 60 Hz, AC only, 15 amp. or more
protected electrical supply. It is recommended that a separate circuit serv­ing only this appliance be provided.

The oven is equipped with a 3-prong grounding plug. It must be plugged
into a wall receptacle that is properly installed and grounded.

Extension Cord

If it is necessary to use an extension cord, use only a 3-wire extension cord that has a 3-blade grounding
plug and a 3-slot receptacle that will accept the plug on the microwave oven. The marked rating of the
extension cord should be AC 240 volt, 15 amp. or more.

Be careful not to drape the cord over the countertop or table where it can be pulled on by children or
tripped over accidentally.

Notes: 1. If you have any questions about the grounding or electrical instructions, consult a qualified

Radio or TV Interference

Should there be any interference caused by the microwave oven to your radio or TV, check that the
microwave oven is on a different electrical circuit, relocate the radio or TV as far away from the oven as
feasible or check position and signal of receiving antenna.

electrician or service person.

2. Neither Sharp nor the dealer can accept any liability for damage to the oven or personal injury
resulting from failure to observe the correct electrical connection procedures.

ABOUT YOUR OVEN

This Operation Manual is valuable: read it carefully and
always save it for reference.

The Sharp High Speed Convection Microwave Cook
Book is valuable asset. Check it frequently for cooking
principles, techniques, hints and recipes.

NEVER use the oven without the turntable and support

nor turn the turntable over so that a large dish could be
placed in the oven. The turntable will turn both clock­wise and counterclockwise.

ALWAYS have food in the oven when it is on to absorb

the microwave energy.

When using the oven at power levels below 100%, you
may hear the magnetron cycling on and off. It is normal
for the exterior of the oven to be warm to the touch
when cooking or reheating.

Condensation is a normal part of microwave cooking.

ABOUT FOOD

Room humidity and the moisture in food will influence
the amount of moisture that condenses in the oven.
Generally, covered foods will not cause as much con­densation as uncovered ones. Vents on the oven back
must not be blocked.

After using, you may hear the sound of the cooling fan.
The fan may continue to operate as long as 5 minutes,
depending on the oven temperature.

Be aware that, unlike microwave-only ovens, convec­tion microwave ovens have a tendency to become hot
during cooking.

The oven is for food preparation only. It should not be
used to dry clothes or newspapers.

Your oven is rated 1000 watts by using the IEC Test
Procedure. In using recipes or package directions,
check food a minute or two before the minimum time
and add time accordingly.

FOOD

Eggs, sausages,
nuts, seeds
fruits &
vegetables

Popcorn

Baby food

General

DO

• Puncture egg yolks before cooking
to prevent “explosion”.

• Pierce skins of potatoes, apples,
squash, hot dogs and sausages so
that steam escapes.

• Use specially bagged popcorn for the
microwave oven.

• Listen while popping corn for the
popping to slow to 1 or 2 seconds or
use special POPCORN pad.

• Transfer baby food to small dish and
heat carefully, stirring often. Check
temperature before serving.

• Put nipples on bottles after heating
and shake thoroughly. “Wrist” test
before feeding.

• Cut baked goods with filling after
heating to release steam and avoid
burns.

• Stir liquids briskly before heating and
allow to stand at least for 20 seconds
after heating before stirring or drink­ing to avoid eruption.

• Use deep bowl, when cooking liquids
or cereals, to prevent boilovers.

DON’T

• Reheat whole eggs.

• Dry nuts or seeds in shells.

• Pop popcorn in regular brown bags

or glass bowls.

• Exceed maximum time on popcorn
package.

• Heat baby food in original jars.

• Heat disposable bottles.

book and interactive display.

ACCESSORIES There are many microwave accessories available for purchase. Evaluate carefully before you purchase
so that they meet your needs. A microwave-safe thermometer will assist you in determining correct doneness and assure
you that foods have been cooked to safe temperatures when using microwave-only cooking. Sharp is not responsible
for any damage to the oven when accessories are used.

INFORMATION YOU NEED TO KNOW

ABOUT CHILDREN AND THE MICROWAVE

Children below the age of 7 should use the microwave
oven with a supervising person very near to them.
Between the ages of 7 and 12, the supervising person
should be in the same room.

The child must be able to reach the oven comfortably;
if not, he/she should stand on a sturdy stool.

At no time should anyone be allowed to lean or swing
on the oven door.

ABOUT MICROWAVE COOKING

• Arrange food carefully. Place thickest areas towards

outside of dish.

• Watch cooking time. Cook for the shortest amount

of time indicated and add more as needed. Food
severely overcooked can smoke or ignite.

• Cover foods while cooking. Check recipe or cook-

book for suggestions: paper towels, wax paper,
microwave plastic wrap or a lid. Covers prevent
spattering and help foods to cook evenly.

• Shield with small flat pieces of aluminum foil any

thin areas of meat or poultry to prevent overcooking
before dense, thick areas are cooked thoroughly.

• Stir foods from outside to center of dish once or twice

during cooking, if possible.

• Turn foods over once during microwaving to

speed cooking of such foods as chicken and ham­burgers. Large items like roasts must be turned over
at least once.

Children should be taught all safety precautions: use
potholders, remove coverings carefully, pay special
attention to packages that crisp food because they
may be extra hot.

Don’t assume that because a child has mastered one
cooking skill he/she can cook everything.

Children need to learn that the microwave oven is not
a toy. See page 29 for Child Lock feature.

• Rearrange foods such as meatballs halfway

through cooking both from top to bottom and from
the center of the dish to the outside.

• Add standing time. Remove food from oven and

stir, if possible. Cover for standing time which allows
the food to finish cooking without overcooking.

• Check for doneness. Look for signs indicating that

cooking temperatures have been reached.

Doneness signs include:

- Food steams throughout, not just at edge.

- Center bottom of dish is very hot to the touch.

- Poultry thigh joints move easily.

- Meat and poultry show no pinkness.

- Fish is opaque and flakes easily with a fork.

ABOUT SAFETY

• Check foods to see that they are cooked to the

United States Department of Agriculture's
recommended temperatures.

TEMP FOOD

160°F

165°F

170°F

180°F

To test for doneness, insert a meat thermometer in a
thick or dense area away from fat or bone. NEVER
leave the thermometer in the food during cooking,
unless using a microwave thermometer when cooking
with only microwave power.

... for fresh pork, ground meat,

boneless white poultry, fish,
seafood, egg dishes and frozen
prepared food.

... for leftover, ready-to-reheat

refrigerated, and deli and carry­out “fresh” food.

... white meat of poultry.

... dark meat of poultry.

• ALWAYS use potholders to prevent burns when

handling utensils that are in contact with hot food.
Enough heat from the food can transfer through
utensils to cause skin burns.

• Avoid steam burns by directing steam away from

the face and hands. Slowly lift the farthest edge of
a dish's covering and carefully open popcorn and
oven cooking bags away from the face.

• Stay near the oven while it's in use and check

cooking progress frequently so that there is no
chance of overcooking food.

• NEVER use the cavity for storing cookbooks or

other items.

• Select, store and handle food carefully to preserve

its high quality and minimize the spread of
foodborne bacteria.

• Keep waveguide cover clean. Food residue can

cause arcing and/or fires.

• Use care when removing items from the oven so

that the utensil, your clothes or accessories do not
touch the safety door latches.

• Keep aluminum foil used for shielding at least 1 inch

away from walls, ceiling and door.
