PFE 591 Inspection and Planned Maintenance
Inspections and planned maintenance are regular equipment checks to detect issues early and ensure optimum performance of the fryer. The link below provides a checklist of the inspection steps you should complete. While all steps should be performed annually, we recommend restaurants with high-volume locations perform more frequent planned maintenance (i.e., quarterly, semi-annually, or other frequency). If you are unsure, please consult with your manager.
