Print one record per candidate. No input fields; no data is sent or stored. Use portrait orientation and disable browser headers/footers.
Unknown fit means hold. Use accessible labels, records or an already safely removed element. Never open a pressurized filter. Use qualified service help and the exact equipment instructions. This is not an opening, installation or restart procedure.
1. Record one candidate—not an assumed equivalent

Do not normalize identifiers or dimensions. Unicel C-7471 lists 26-1/16-inch length; Pleatco PCC105 lists 26 inches. Keep each attached to its catalog, not a universal tolerance. The retrieved Pleatco catalog conflicts on R173476 / R173576; R173476 compatibility remains unconfirmed here. Do not order on that cross-reference alone. Square footage or a photograph cannot establish fit.
