Assembly
1. Install a gasket onto frame. 2. If using a mesh overlay or filter tube, slide it over the strainer element. 3. Place element over frame. 4. Place end plug over the frame and element, centering the cap in the element. 5. Place the retaining clip into the hole in the frame, positioning the retaining clip perpendicular to the frame. 6. Feed clip through the hole, keeping it perpendicular to the frame until the clip center position is in the frame hole. Figure 2: Straight-Line Strainer Components
7. Compress cap to the element by swinging down the retaining clip down over the element. The element should no longer move freely in the cap and frame. If there is free movement, the clip may need to be replaced, as it will wear over time with use. 8. Disassemble by reversing the above listed steps. Note that the retaining clip should always be installed and/or removed in a perpendicular position to the frame. Failure to maintain a perpendicular position could result in damaging/bending the clip, preventing proper compression of the cap to the element.
Cleaning* 1. Turn off and lock out any pumps and/or
equipment connected to the strainer process line.
2. Ensure that all pressure has been relieved from the system the strainer is installed on. 3. Close any available blocking / isolation valves. 4. Remove and disassemble the strainer internals. 5. Remove mesh overlay / filter tube if present. Mesh overlay can be cleaned; discard filter tube after each use. 6. Use a hose to spray the insert off with water to remove loose debris.
Figure 3: COP Parts Washer Cleaning
7. Clean the insert 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. 8. Rinse with appropriate water supply and inspect all parts for cleanliness and damage. 9. 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.
