INSTALLATION INSTRUCTIONS
Unpacking
1. Empty the microwave oven of any packing materials.
2. Clean the inside with a soft, damp cloth.
3. Check for damage, such as:
nA door that is not lined up correctly,
nDamage around the door, or
nDents on the interior or exterior of the microwave oven.
If there is any damage, do not operate the microwave
oven until a designated service technician has checked
itandmade any needed repairs.
NOTE: To avoid damage to the microwave oven, do not remove
microwave inlet cover. See the “Parts and Features” section.
Location Requirements
nPlace the microwave oven on a cart, counter, table, or shelf
that is strong enough to hold the microwave oven and the
food and utensils you place inside it.
nThe microwave oven should be at a temperature above
50°F (10°C) for proper operation.
nDo not block the exhaust vents or air intake openings. Allow
a few inches of space at the back and side of the microwave
oven where the exhaust vents are located. Blocking the
exhaust vents could cause damage to the microwave oven
as well as poor cooking results.
nMake sure the microwave oven legs are in place to ensure
proper airow. If vents are blocked, a sensitive thermal
device may automatically turn the microwave oven off. The
microwave oven should work properly once it has cooled.

MICROWAVE OVEN USE
A magnetron in the microwave oven produces microwaves which
reect off the metal oor, walls, and ceiling and pass through the
turntable and appropriate cookware to the food. Microwaves are
attracted to and absorbed by fat, sugar, and water molecules
in the food, causing them to move, producing friction and heat
which cooks the food.
nTo avoid damage to the microwave oven, do not lean on or
allow children to swing on the microwave oven door.
nTo avoid damage to the microwave oven, do not operate
microwave oven when it is empty.
nBaby bottles and baby food jars should not be heated in
microwave oven.
nClothes, owers, fruit, herbs, wood, gourds, and paper,
including brown paper bags and newspaper, should not be
dried in the microwave oven.
nParafn wax will not melt in the microwave oven because it
does not absorb microwaves.
nUse oven mitts or pot holders when removing containers
from microwave oven.
nDo not overcook potatoes. At the end of the recommended
cook time, potatoes should be slightly rm. Let potatoes
stand for 5 minutes. They will nish cooking while standing.
nDo not cook or reheat whole eggs inside the shell. Steam
buildup in whole eggs may cause them to burst, requiring
signicant cleanup of microwave oven cavity. Cover
poachedeggs and allow a standing time.
Food Characteristics
When microwave cooking, the amount, size and shape,
startingtemperature, composition, and density of the food
affectcookingresults.
Amount of Food
The more food heated at once, the longer the cook time
needed.Check for doneness and add small increments
oftimeifnecessary.
Size and Shape
Smaller pieces of food will cook more quickly than larger pieces,
and uniformly shaped foods cook more evenly than irregularly
shaped food.
Starting Temperature
Room temperature foods will heat faster than refrigerated foods,
and refrigerated foods will heat faster than frozen foods.
Composition and Density
Foods high in fat and sugar will reach a higher temperature and
will heat faster than other foods. Heavy, dense foods, such as
meat and potatoes, require a longer cook time than the same
size of a light, porous food, such as cake.
Cooking Guidelines
Covering
Covering food helps retain moisture, shorten cook time, and
reduce spattering. Use the lid supplied with cookware. If a
lid isnot available, wax paper, paper towels, or plastic wrap
approved for microwave ovens may be used. Plastic wrap
should be turned back at one corner to provide an opening to
vent steam. Condensation on the door and cavity surfaces is
normal during heavy cooking.
Stirring and Turning
Stirring and turning redistribute heat evenly to avoid overcooking
the outer edges of food. Stir from outside to center. If possible,
turn food over from bottom to top.
Arranging
If heating irregularly shaped or different‑sized foods, arrange
the thinner parts and smaller‑sized items toward the center. If
cooking several items of the same size and shape, place them
ina ring pattern, leaving the center of the ring empty.
Piercing
Before heating, use a fork or small knife to pierce or prick foods
that have a skin or membrane, such as potatoes, egg yolks,
chicken livers, hot dogs, and sausage. Prick in several places
toallow steam to vent.
Shielding
Use small, at pieces of aluminum foil to shield the thin pieces
of irregularly shaped foods, bones and foods such as chicken
wings, leg tips, and sh tails. See the “Aluminum Foil and Metal”
section rst.
Standing Time
Food will continue to cook by the natural conduction of heat
even after the microwave cooking cycle ends. The length of
standing time depends on the volume and density of the food.

9
Cookware and Dinnerware
use oven mitts or pot holders when handling because any dish
may become hot from heat transferred from the food. Do not
use cookware and dinnerware with gold or silver trim. Use the
following chart as a guide, then test before using.
