UNPACKING AND INSTALLATION INSTRUCTIONS

Unpacking and Examining Your Oven

Remove:

1. all packing materials from inside the oven cavity;
however, DO NOT REMOVE THE WAVEGUIDE
COVER, which is located on the right cavity wall.

Read enclosures and SAVE the
Operation Manual.

2. the feature sticker, if there is
one, from the outside of the door.

Check the oven for any damage,
such as misaligned or bent door,

damaged door seals and sealing
surfaces, broken or loose door hinges and latches and
dents inside the cavity or on the door. If there is any
damage, do not operate the oven and contact your
dealer or SHARP AUTHORIZED SERVICER.

Choosing a Location for Your Oven

Y ou will use the oven frequently so plan its location for
ease of use. It's wise, if possible, to have counter space
on at least one side of the oven. Allow at least 2 inches

on the sides, top and at the rear of the oven for air
circulation. Do not place or install the oven in any area
where heat and steam are generated; for example,
next to or above a conventional gas or electric range
or above a conventional wall oven. Heat and steam
may damage the electronics or the mechanical parts of
the oven.

Built-in Kit

Your oven can be built into a cabinet or wall—not
near or above a heat source—using Sharp’s white
Built-In Kit RK-46W24 for the R-426HW, black
RK-46K24 for the R-426HK, R-426HQ and stainless
steel RK-46S24 for the R-426HS. If your dealer does
not stock the kit, it can be ordered directly from the
Sharp Accessories and Supplies Center. Have your
credit card number available and call toll-free:
1-800-642-2122 for ordering the kit to be sent to
your address.

The kit includes ducts, finish trim strips and easy-to­follow 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 120 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. Should you only have a
2-prong outlet, have a qualified electrician install a correct wall receptacle.

A 3-prong adapter may be purchased and used temporarily if local codes allow.
Follow package directions.

A short power-supply cord is provided to reduce risk of becoming entangled in
or tripping over a longer cord.

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 115­120 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 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.

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.

INFORMATION YOU NEED TO KNOW

ABOUT YOUR OVEN

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

A good microwave cookbook is a valuable asset.
Check it for microwave cooking principles, techniques,
hints and recipes. See pages 19 and 20 for ordering
the Ultimate Accessory, the Sharp Carousel Microwave
Cookbook.

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

ABOUT FOOD

FOOD

Eggs, sausages,
fruits &
vegetables

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

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

DO

for the exterior of the oven to be warm to the touch
when cooking or reheating.

Condensation is a normal part of microwave cooking.
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.

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

Your oven is rated 1200 watts by using the IEC
Test Procedure method. In using recipes or package
directions, check food a minute or two before the minimum
time and add time accordingly.

DON’T

• Cook eggs in shells.

• Reheat whole eggs.

• Dry nuts or seeds in shells.

Popcorn

Baby food

General

• 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 and after
heating to avoid “eruption”.

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

4

• Pop popcorn in regular brown bags
or glass bowls.

• Exceed maximum time on popcorn
package.

• Heat disposable bottles.

• Heat bottles with nipples on.

• Heat baby food in original jars.

• Heat or cook in closed glass jars or air
tight containers.

• Can in the microwave as harmful
bacteria may not be destroyed.

• Deep fat fry.

• Dry wood, gourds, herbs or wet papers.

INFORMATION YOU NEED TO KNOW

ABOUT UTENSILS AND COVERINGS

It is not necessary to buy all new cookware. Many
pieces already in your kitchen can be used success­fully in your new microwave oven. Make sure the
utensil does not touch the interior walls during cooking.

Use these utensils for safe microwave cooking
and reheating:

• glass ceramic (Pyroceram®), such as
Corningware®.

• heat-resistant glass (Pyrex®)

• microwave-safe plastics

• paper plates

• microwave-safe pottery, stoneware and
porcelain

• browning dish (Do not exceed recommended
preheating time. Follow manufacturer's
directions.)

These items can be used for short time reheat­ing of foods that have little fat or sugar in them:

• wood, straw, wicker

DO NOT USE

• metal pans and bakeware

• dishes with metallic trim

• non-heat-resistant glass

• non-microwave-safe plastics (margarine tubs)

• recycled paper products

• brown paper bags

• food storage bags

• metal twist-ties

Should you wish to check if a dish is safe for
microwaving, place the empty dish in the oven and
microwave on HIGH for 30 seconds. A dish which
becomes very hot should not be used.

The following coverings are ideal:

• Paper towels are good for covering foods for re­heating and absorbing fat while cooking bacon.

• Wax paper can be used for cooking and
reheating.

• Plastic wrap that is specially marked for micro­wave use can be used for cooking and reheat­ing. DO NOT allow plastic wrap to touch food.
Vent so steam can escape.

• Lids that are microwave-safe are a good choice
because heat is kept near the food to hasten
cooking.

• Oven cooking bags are good for large meats or
foods that need tenderizing. DO NOT use metal
twist ties. Remember to slit bag so steam can
escape.

How to use aluminum foil in your microwave
oven:

• Small flat pieces of aluminum foil placed
smoothly on the food can be used to shield
areas that are either defrosting or cooking too
quickly.

• Foil should not come closer than one inch to any
surface of the oven.

Should you have questions about utensils or coverings,
check a good microwave cookbook or follow recipe
suggestions.

ACCESSORIES There are many microwave accesso-

ries 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. Sharp is not
responsible for any damage to the oven when acces­sories are used.

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.

1.426HK/W/S #350MRK1 10/17/03, 10:59 AM5

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 17 for Child Lock feature.

INFORMATION YOU NEED TO KNOW

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 cook­book 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.

• 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 it is approved for microwave oven use.

...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 carry-

out “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.
