A ground connection to a cold water pipe must have a metal continuity to electrical ground and must not be
interrupted by insulating materials. Any insulating materials must be jumped as shown in the installation
instructions.
Use only connectors specially designed and certified for joining copper and aluminum to splice the appliance

model and serial number plate (see page 3). The electrical service must be installed or changed only by a
licensed electrician.
Do not operate this appliance if it has a damaged electrical cord.
Failure to install the mounting screws may result in movement or tipping of the oven during use and may result

Do not line the oven with aluminum foil or other materials. These items can melt or burn up during self-
cleaning and cause permanent damage to the oven.
Do not use a steam cleaner to clean the oven. Steam could penetrate electrical components and cause a short
circuit.
Do not leave metal objects, such as aluminum foil, the meat probe, or cookie sheets, on the floor of the oven.
Objects left on the bottom of the oven could trap heat in the bottom, damaging the bake element. In addition,
the objects themselves could be damaged.
Do not air intakes or exhaust slots, anywhere on the oven to become obstructed at any time. Do not operate
the oven if the exhaust deflector below the oven door is bent.
The oven automatically locks the oven door during self-cleaning. Do not try to force the door open after it is
locked. Damage to the door and the door latch may result.
Before self-cleaning the oven, remove the broiler pan grill and pan, oven racks, convection filter, meat probe,
and any other utensils.
Use only the cleaning solutions specified in the use and care manual to clean the inside or outside of the oven.
Other cleaning solutions could produce hazardous fumes, cause corrosion of the metal parts, and could
permanently damage the finishes. Clean only those parts listed in the use and care manual.
Take extreme caution when handling the door gasket. Damaging the door gasket in any way may eliminate the
required tight door seal. Clean the gasket only as specified in the use and care manual.
Use of meat probes other than the one provided with the oven may result in damage to the meat probe and/or
the oven.
