IMPORTANT SAFETY INSTRUCTIONS
 WARNING
NEVER use this appliance as storage space. Doing so may result
in carbon monoxide poisoning and overheating of the oven.
 WARNING
NEVER cover any slots, holes or passages in the oven bottom or
cover an entire rack with materials such as aluminum foil. Doing so
blocks air flow through the oven and may cause carbon monoxide
poisoning. Aluminum foil linings may also trap heat, causing a fire
hazard.

Broiling food for an excessively long time can cause it to dry out
and may result in the food catching fire.
Do not exceed recommended broiling times.

Some foods dry out very quickly and can be ignited by high
broiling temperatures. Do not use broiling modes for crisping rolls or
bread, or to dry flowers or herbs. Instead use the Convection Bake
 or Surround  modes.

Use caution when using alcohol in your recipes. Alcohol
evaporates at high temperatures but may, in rare circumstances,
combust on the hot heating elements.

Plastic containers, which are not heat-resistant, melt and may
ignite at high temperatures and can damage the oven. Use only
plastic containers that are indicated by the manufacturer as being
suitable for use in ovens.

When residual heat is used to keep food warm, the high level of
humidity and condensation can cause damage in the oven. The
control panel, countertop or cabinetry may also be damaged.
Do not switch the oven off completely while food is inside it, but
select the lowest possible temperature for the oven mode you are
using. This will ensure the fan will automatically continue to run.
