8) Clean the insert and O-rings 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. 9) Rinse with appropriate water supply and inspect all parts for cleanliness and damage. 10) Reassemble the strainer as described above. *These are recommended cleaning instructions only. Follow any plant sanitation standard operating procedure (SSOP) that your facility may have in place. A tri-clamp cap can be attached to the strainer body, which can then be cleaned-in-place (CIP) if desired during COP of the strainer element. Maintenance During normal disassembly, cleaning, and reassembly, inspect the strainer for the following: 1) Soil. Inspect for soil particulates or foreign matter caught in the insert. Remove as necessary. 2) Gasket/O-Ring. Inspect for cuts, abrasions, tears, holes, deformity, or other visible damage. Replace as necessary. 3) Element. Check for bent components, holes, or other damage. Replace as necessary. 4) Mesh Underlay (if applicable). Inspect for tears or other damage. Replace as necessary. o Remove and clean strainer element at least once per shift. o More frequent removal and cleaning may be required with heavier soils.
