Where should the filter pan and its components be rinsed and washed?

The dish sink is the appropriate place for rinsing and washing the filter pan and its components because it is specifically designed for cleaning dishes and utensils that come into contact with food. This sink typically has appropriate sanitation measures in place, ensuring that these components are cleaned effectively and without contamination.

Using the dish sink helps maintain food safety standards by preventing cross-contamination that could occur if the washing were done in other locations, such as a kitchen sink intended for food prep or a bathroom sink, which is not suitable for food-related items. The fryer unit would also not be appropriate as it is not designed for washing and does not provide the necessary sanitation for cleaning components. Therefore, the dish sink is the most logical and safest option for handling the filter pan and its components.
