oven off and disconnect the power cord, or shut off power at the
fuse or circuit breaker panel.
dDO NOT use the cavity for storage. DO NOT leave paper
products, cooking utensils, or food in the cavity when not in use.

WARNING

Liquids such as water, coffee, or tea can 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:

iDo not overheat the liquid.
iStir the liquid both before and halfway through heating it.
iDo not use straight-sided containers with narrow necks.
iAfter heating, allow the container to stand in the microwave oven for a
short time before removing the container.
vUse extreme care when inserting a spoon or other utensil into the
container.

General Description

The Speed Oven uses a combination of very high temperature top and bottom air
combined with microwave, to cook a wide range of both chilled and frozen
products in a fraction of the normal cooking time.

The unique features of its fully programmable controller allows you to develop the
ideal cooking profile for every product which can then be stored to ensure
repeatability of both temperature and quality every time. The controller can store
up to 64 recipes at any one time, allowing you to store complete menus if required.

The oven takes 13 minutes to heat up from cold after which it has instant response.

The oven can operate within a range of 350 F and 500F and care
taken when putting in or taking out products, from the oven, as Internal Surfaces

are Hot

must always be
