IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
The safety instructions below will tell you how to use your oven and avoid harm to yourself
or damage to your oven.
•Read and follow the specific
PRECAUTIONS TO AVOID
POSSIBLE EXPOSURE TO
EXCESSIVE MICROWAVE
ENERGY
found on page 2.
•Turn the fan on to disperse steam or smoke under
the hood. Keep the area under the hood properly
ventilated at all times. Turn off cooking equipment if
you see flames or a fire occurs.
WARNING
Hazards or unsafe practices
that may result in severe
personal injury or death.
CAUTION
Hazards or unsafe practices
that may result in minor
personal injury or property
damage.
NOTE: Turn the microwave’s vent fan on
whenever you use the oven range cooktop
below it.The fan captures smoke, steam, and
odors and also prevents the heat from the
cooktop from damaging microwave components.
If the microwave is cooking, the vent fan turns on
automatically if the sensors detect too much heat
from the cooktop. This is normal, and is designed
to prevent microwave component damage.

3-wire extension cord that has a 3-blade grounding
plug, and a 3-slot receptacle that will accept the plug
on the appliance. The marked rating of the extension
cord should be equal to or greater than the electrical
rating of the appliance.
For a permanently connected appliance:
This appliance must be connected to a grounded,
metallic, permanent wiring system, or an equipment
