8. Remove filter bag (if present) - discard filter bag after each use. 9. Use a hose to spray the insert off with water to remove loose debris.
10. Clean the strainer element, o-rings, and other internals using a clean-out-of-place (COP) parts washer or other automated system running at an adequate temperature, chemical concentration, and amount of time to remove all soil residue. If automated cleaning is not available, manually clean soil residue off the element using a scrub device, water source, chemical and gloves. 11. Rinse with appropriate water supply and inspect all parts for cleanliness and damage. 12. Reassemble the strainer as described in the assembly section. *These are recommended cleaning instructions only. Follow any plant sanitation standard operating procedure (SSOP) that your facility may have in place. Maintenance During normal disassembly, cleaning, and reassembly, inspect the key areas of the strainer that may require maintenance: 1) Soil. Inspect for soil particulates or foreign matter caught in the element. Remove as necessary. 2) O-Rings/Gaskets. Inspect for cuts, abrasions, tears, holes, deformity, or other visible damage. Replace as necessary or no longer than a recommended annual basis. 3) Element. Check for bent components, abnormal holes, or other wear and tear or damage. Replace as necessary. 4) Filter Bags (if applicable). Inspect for tears or other damage. Filter tubes are considered “single- use” and should be replaced in between each production run and/or cleaning procedure. a. The locking latch clip should snap under the handle and hold the media ring firmly in place. If bent or fit is not firm, replace these parts. Remove and clean the strainer element at least once per shift. More frequent removal and cleaning may be required with heavier soils.
