Overview, which materials are suitable for
microwaves and for high temperatures
Material Microwave suitable
Aluminium Foil In certain cases
Metal pots with No
high edge
Metal pots not hig- Yes
her than 3-4cm
Glass Yes
Glass with metal No
decorative elements
Thin glass No
Plastic Yes
Porcelain Yes
Porcelain with No
metal decorative
elements
Paper/Foils Yes
Never use hermetic closed containers, cans baby bottles, plastic containers
etc as this can cause danger of explosion. Always remove the lid or put
holes in it.
To test if a container is microwave safe put a cup of water inside the container and
place it in the middle of the glass turntable.
Start the microwave for ca 1min on max power. Is the container cold and the water
hot then it can be used. Is the container warm or hot, then it is not suitable.
If any sparks occur, then switch off the microwave instantly. The appliance must be
supervised permanently.

Remark
Can be used in small quantities to
avoid overcooking. Risk to have an
electrical arc when the foil is to near to
the side walls or to much is used.
Danger of electrical arcing and fire
Place in the middle of the turntable,
min 2cm distance to the walls
Danger of electrical arcing
Can crack because of high tempera-
tures.
If the plastic is temperature resisting
Some containers can deform and chan-
ge the colout. Never seal the container
Danger of electrical arcing
Short time use inside Microwave, but
not at the grill or hot Air Function
What is microwave?
Electrical energy is transformed inside a magnetron into microwaves.
The microwaves makes water molecules, which are in food, start to oscillate. The
friction between the molecules heats up the food. The microwaves are reflected from
the interior walls of the oven on the food.
The cold microwaves are absorbed from the water molecules or the fat of the food.
Microwaves enter into the food ca 4cm and cooking the food from the outside to the
inside. Therefore some time after switching off the appliance is recommended, as the
food is still cooking to the inside.
The cooking utensils are getting hot up by the food. Therefore always use cooking
gloves to remove them.
Cooking utensils made from metal cannot be passed from the microwaves and must
therefore normally not be used.
Grill
At the upper side of the appliance there is a 1200W heating element for grilling or au
four of food.
Always take care to have enough distance between the food and the heating ele-
ment, to avoid any ignition of splattering oil. To reduce the grilling time- when the
food is slightly brown- the microwave can be added. Always take care, that only one
wire grill is used when using the microwave function.
Hot Air
In the inside of the back plate of the oven there is a adjustable (100-220°C) heating
element combined with a convection unit. By the circulating hot air it is possible to
cook food on different levels. By the circulation the food preparation is more energy
efficient.
When using hot air and microwave at the same time it is important to use only one
wire grill on the glass turntable. Always place the wire grill in the middle of the glass
turntable.
