CHAPTER 5: CLEANING AND MAINTENANCE
5-2
5.3 Daily— Close Of Business
At the close of a working day, filter the oil in all fryers. When the last fryer is filtered, follow these
steps:
1. Ensure the flexible hose and pump lines are clear by running the filter pump for an
additional 15–30 seconds after air bubbles start coming from the oil return line. Drain the
flexible hose as much as possible, especially if solid shortening is used.
2. Remove the filter pan cover and hold-down ring, and then remove the filter paper and filter
paper support screen.
3. Discard filter paper.
4. Wash all filter components with hot soapy water and rinse. DO NOT use soap and/or water
inside the filter pan. Wipe residual oil and sediment from inside the filter pan with a clean
cloth or paper towel.
5. Rinse all parts with clean water (except filter pan interior), and then dry all filter parts
thoroughly before reassembling.
6. Check the hose fitting on the pump and ensure that it is tight. Check plumbing for leaks.
See Chapter 6 for service procedures. Check plumbing for leaks.
5.4 Weekly
Follow the same procedure as for "Daily", with these additional steps:
• Clean built-up residue and debris from filter pan by wiping with a clean cloth or paper
towel. DO NOT use soap and/or water inside the filter pan. Ensure all components fit
properly and function correctly.
• Clean thoroughly under, around, and behind the fryers and filtering area with hot soapy
water and rinse.
• Check the hose connection and tighten if hose becomes loose and starts to leak oil.
