No, the TF1 Omega Filter has been designed to ensure that even when it reaches a level of maximum collection, system water can still pass through the filter, short-circuiting the body, and flowing freely through the manifold.
Does Fernox Cleaner F3 need to be flushed out of the system?
Fernox Cleaner F3 should ideally circulate through the system for at least one hour, or up to a week. Afterward, it should be drained, and the system flushed and cleaned before adding Fernox Protector F1 or Protector + Filter Fluid, together with a Fernox TF1 Filter, to protect the system from further corrosion and scale formation.
