E. Filter Bypasses Dirt:
To avoid severe injury or major property damage, exactly fol-
low instructions under “Disassembly” and “Assembly” (Pages 11 and 12)!
1. Air bleed tube and/or tube filter not in position. Exactly follow instruc-
tions in “Filter Disassembly/Assembly Procedure”, Pages 11 and 12, and
reinstall correctly.
2. Element cloth torn or punctured; replace element.
3. Filter element is not seated properly in filter base; follow instructions
under “Filter Disassembly/Reassembly”, Pages 11 and 12, and reposition
properly.
4. Filter is plumbed backwards and element cloth is ruptured - replumb
properly and replace element.
5. Model PTM50 only: hold down strap is not in position or is missing and
element is floating. See “Filter Disassembly/Assembly,” Pages 11 and 12.
Replace hold down strap if missing; reposition strap if present.
6. Colloidal fines (very small suspended dirt particles) are present and pass-
ing through element covering. Floc with alum, or if fines have already
settled, vacuum to waste.
