q Alcoholic drinks must not be overheated. There is
a risk of explosion.
q Do not heat any meals in heat retaining packages
as they could ignite. Food in containers made from
plastic, paper or other combustible materials must
be monitored during heating. Airtight packaging
may burst when food is heated.
q The oven door must not be opened if smoke is
visible inside the oven. Should this happen, switch
off the appliance and isolate the cooker from the
power supply at the fuse box.
q Never cook eggs in their shells nor heat up
hard boiled eggs, as they may crack or explode.
The same applies to shellfish and crustaceans.
Always prick the yoke first for fried or poached
eggs.
q Always prick the skin of foodstuffs with hard crusts
or skins such as apples, tomatoes, potatoes and
sausages before cooking to prevent the skin from
bursting.
q Keep an eye on the oven when you are defrosting
or heating foods such as herbs, fruit or
mushrooms or foods with a low water content
such as bread as overdrying can result in a fire
hazard.
q Never heat up cooking oil in a microwave as it
could ignite.
q Porcelain or ceramic ovenware can have small
perforations in the handles or lid. These
perforations conceal a cavity below. Any liquid that
penetrates this cavity may cause the ovenware to
crack.
q Always use the microwave settings and cooking
times specified in the instruction manual. If you
select a heat setting that is too high or a cooking
time that is too long, this may cause the food to
ignite and the appliance to be damaged.
