Never pour water into the hot cooking compartment.
This will cause steam. The temperature change can
cause damage to the ceramic floor panel.
Only leave the cooking compartment to cool with the
door closed. Do not trap anything in the appliance
door. Even if the door is only slightly ajar, the fronts of
adjacent units may be damaged over time.
If the seal is very dirty, the appliance door will no
longer close properly during operation. The fronts of
adjacent units could be damaged. Always keep the
seal clean.
Do not switch on the microwave unless there is food
in the cooking compartment. The appliance may be
overloaded if it is switched on without any food inside.
An exception to this rule is for brief testing of
ovenware (see notes on ovenware).
