Westinghouse PHR222U is a built-in electric ceramic cooktop designed for household and similar applications. It features a smooth glass surface with concealed heating elements and energy regulators for precise temperature control. Choose the desired element, set the control knob to the high setting for quick boiling, and then adjust to the preferred heat level. Warning lights indicate when the cooktop is still hot after turning off. Use flat-bottomed pots and pans with heavy bases for optimal cooking performance. Avoid oversized pots and pans that overhang the elements by more than 50mm.
