Assembly 1. Install the O-ring on the basket, by sliding it over the basket and into the O-ring groove. Do not use sharp tools, as these will damage the O-ring. 2. For perforated baskets with bag filters, slide the bag into the inside of the basket until the bag ring is seated in the basket ring. a. Place the media positioning ring on top of the bag ring with the notches at approximately 90 degrees to the handle. b. Place the ends of the locking latch (wire clip) into the notches on the media positioning ring and snap the locking latch under the basket handle into the notch provided on the bottom side of the basket handle. 3. Place the cover O-ring in the O-ring groove on the top of the body ring. On horizontally mounted units this may require extra care to ensure that the o-ring does not fall out of the groove. 4. Place the basket assembly into the housing and slide down into the strainer housing until the O-ring slips into the seat. The basket handle must be inside of the housing so that the cover may be closed. 5. Close the cover and watch for interference between the cover and basket handle. 6. Rotate the cover swing bolts into position and spin the hand knobs to clamp down the cover (hand tighten only).

NOTE: For rubber o-rings, periodically apply food grade sanitary lubricant containing no mineral oils to the o-ring for ease of installation.
Cleaning* 1. Turn off and lock out any pumps and/or equipment connected to the strainer process line. 2. Relieve pressure using the basket strainer bleed valve located on the cover of the strainer. 3. Ensure that all pressure has been relieved from the system the strainer is installed on. 4. Close any available blocking / isolation valves. 5. Open the basket strainer cover. 6. Grasp the basket handle and pull slightly off-center to loosen the o-ring. 7. Pull the basket out of the housing. 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.
Figure 2: COP Parts Washer Cleaning
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.
