41、ns must be cleaned and flushed as well. Residual flush solvent must be pumped from the system prior to the introduction of the primer. Note: If the system is down for more than 6 hours, the Shut down procedure must be followed. Shutting Down the System It is necessary to flush the system with Methyl

42、 Ethyl Ketone to remove residual primer. Once the residual primer has been removed, the system should be pumped dry of the flush solvent. Tubing Polyethylene or Polytetrafluoroethylene tubing must be used. Nylon tubing will allow the permeation of moisture, resulting in the premature curing of the p
