models feature (5) rack position. Make sure the tray support and shelves are correctly positioned inside
the cooking chamber and securely installed. Only load the rated number of trays per oven size. Do not
overload the chamber or it will affect cooking performance and results.
It is normal for an unpleasant smell to be noticeable the rst time the oven is used. This is caused by
burning off residue from the manufacturing process. Set the oven to 450 degrees Fahrenheit until the
smell dissipates, for about 30 minutes.
