Panasonic NN-S433WL Manual De Usuario

•

use your oven for home canning, your

oven cannot maintain the food at the proper can-
ning temperature. Improperly canned food may
spoil and be dangerous to consume.

• 

dry meats, herbs, fruits or vegetables in

your oven. Small quantities of food or foods with
low moisture content can dry out, scorch or catch
on fire if overheated.

3) DEEP FAT FRYING
•

attempt to deep fat fry in your

microwave oven. Cooking oils may burst into
flames and may cause damage to the oven and
perhaps result in burns. Microwave utensils may
not be able to withstand the temperature of the
hot oil, and could shatter or melt.

4) FOODS WITH NONPOROUS SKINS
• Potatoes, apples, whole eggs, egg yolks,

whole squash and sausages are examples of
foods with nonporous skins. These types of
foods must be pierced before microwave cooking
to prevent their bursting.

• Use fresh potatoes for baking and cook until just

done. Use recommended weights for programmed
cooking. Overcooking causes dehydration and
may result in a fire.

5) LIQUIDS
• Liquids can become "superheated" in a

microwave, and when the container is moved in
any way, the superheated liquids can
"explode" out of the container.
"Superheated" water is hotter than boiling
water, EVEN THOUGH IT DOES NOT
APPEAR TO BUBBLE. To reduce the possibility

of this occurrence:
Always make sure that liquids are stirred
vigorously before heating to assure that the
liquid is mixed with air. NEVER HEAT LIQUIDS
FOR AN EXCESSIVE LENGTH OF TIME.

6) GLASS TRAY / COOKING UTENSILS / FOIL
• Cooking utensils get hot during microwaving. Heat

is transferred from the HOT food to the container
and the Glass Tray. Use potholders when remov-
ing utensils from the oven or when removing lids
or plastic wrap covers from cooking utensils to
avoid burns.

• The Glass Tray will get hot during cooking. It

should be allowed to cool before handling or
before paper products, such as paper plates or
microwave popcorn bags, are placed in the oven
for microwave cooking.

• When using foil, skewers, warming rack or uten-

sils made of metal in the oven, allow at least 1-
inch (2.5 cm) of space between metal material
and interior oven walls. If arcing occurs (spark-
ing), remove metal material (skewers etc.) and/or
transfer to a non-metallic container.

• Dishes with metallic trim should 

be used, as

arcing may occur.

• If an entree is heated in a foil tray, maintain at

least 1-inch (2.5 cm) spacing from the oven walls.

7) PAPER TOWELS / CLOTHS
•

use paper towels or cloths which con-

tain a synthetic fiber woven into them. The syn-
thetic fiber may cause the towel to ignite. Use
paper toweling under supervision.

8) BROWNING DISHES / OVEN COOKING BAGS
• Browning dishes or grills are designed for

microwave cooking only. Always follow instruc-
tions provided by the manufacturer. 

preheat browning dish more than 6 minutes.

• If an oven cooking bag is used for microwave

cooking, prepare according to package directions.

use a wire twist-tie to close bag,

instead use plastic ties, cotton string or a strip cut
from the open end of the bag.

9) THERMOMETERS
•

use a conventional meat thermometer

in your oven. Arcing may occur.  Microwave-safe
thermometers are available for both meat and
candy.

10) BABY FORMULA / FOOD
• 

heat baby formula or food in the

microwave oven. The glass jar or surface of the
food may appear to be only warm while the interi-
or can be so hot as to burn the infant’s mouth and
esophagus.

11) REHEATING PASTRY PRODUCTS
• When reheating pastry products, check tempera-

tures of any fillings before eating. Some foods
have fillings which heat faster and can be
extremely hot, while the surface remains warm to
the touch (ex. Jelly Donuts).

12) GENERAL OVEN USAGE GUIDELINES
•

use the oven for any reason other than

the preparation of food.

•

leave oven unattended while in use.

Popcorn may be popped in a microwave oven
corn popper. Microwave popcorn which pops in
its own package is also available. Follow pop-
corn manufacturers’ directions and use a brand
suitable for the wattage of your microwave oven.

TO TEST A CONTAINER FOR SAFE MICROWAVE OVEN USE: Fill a 1- cup glass measure with water
and place it in the microwave oven along with the container to be tested; heat one (1) minute at P10
(HIGH). If the container is microwave oven-safe (transparent to microwave energy), the container should
remain comfortably cool and the water should be hot. If the container is hot, it has absorbed some
microwave energy and should NOT be used. This test cannot be used for plastic containers.
