Miele H 136 MB Operating Instructions Manual page 19

Plastic containers must only be used
for Microwave mode alone and not in
conventional oven mode.
Plastics must be heat-resistant to a
minimum of 180 °C. Otherwise the
plastic may melt and fuse with the food.
Special plastic utensils, designed for
use in microwave ovens are available
from good retail outlets. Melamine ware
is not suitable as it absorbs energy and
heats up. When purchasing plastic-
ware, make sure that it is suitable for
use in a microwave oven.
Disposable containers, such as trays
made from polystyrene, can only be
used for very short timed warming and
reheating of food.
Plastic boiling bags can be used for
cooking and reheating. To reduce the
risk of the bag bursting, they should be
pierced first so that steam can escape
and prevent a build-up of pressure.
Roasting tubes should be about 40 cm
longer and roasting bags about 20 cm
longer than the food being roasted,
and carefully tied with string. Turn the
ends over and secure them. Holes
should be made according to the manu-
facturer's instructions.Do not use metal
clips or wire ties, even if bound by
paper. There is a danger that they will
ignite when heated.
Wooden dishes are not suitable.
Moisture contained in the wood evap-
orates when exposed to microwave en-
ergy, causing the wood to dry and
crack.
Only those plastic disposable con-
tainers which are specified by the
manufacturer as suitable for use in a
microwave oven may be used.
Do not leave the oven unattended
when re-heating or cooking food in
disposable containers made of
plastic paper or other inflammable
material.
Disposable containers are not always
recyclable or degradable.
