WARNING
⚠
CAUTION
⚠
WARNING
⚠
Liquids such as water, coee, or tea are able to be
overheated beyond the boiling point without appearing
to be boiling due to surface tension of the liquid. Visible
bubbling or boiling when the container is removed from
the microwave oven is not always present. THIS COULD
RESULT IN VERY HOT LIQUIDS SUDDENLY BOILING
OVER WHEN A SPOON OR OTHER UTENSIL IS
INSERTED INTO THE LIQUID. To reduce the risk of injury
to persons:
i. DO NOT overheat the liquid.
ii. Stir the liquid both before and halfway through heating it.
iii. DO NOT use straight-sided containers with narrow necks.
iv. After heating, allow the container to stand in the
microwave oven for a short time before removing the
container.
v. Use extreme care when inserting a spoon or other utensil
into the container.
To avoid personal injury or property damage, observe the following:
1. DO NOT deep fat fry in oven. Fat could overheat and be
hazardous to handle.
2. DO NOT cook or reheat eggs in shell or with an unbroken
yolk using microwave energy. Pressure may build up and
erupt. Pierce yolk with fork or knife before cooking.
3. Pierce skin of potatoes, tomatoes, and similar foods before
cooking with microwave energy. When skin is pierced,
steam escapes evenly.
4. DO NOT operate equipment without load or food in oven
cavity.
5. Use only popcorn in packages designed and
labeled for microwave use. Popping time varies depending
on oven wattage. DO NOT continue to heat after popping
has stopped. Popcorn will scorch or burn. DO NOT leave

into a separate circuit with the electrical rating as provided in product specications (available at www.acpsolutions.com) and
the oven’s serial plate / rating label. When the oven is on a circuit with other equipment, an increase in cooking times may be
required and fuses can be blown.
