Installation: carefully clean the thread connection surface of all pipes before installing the Plastic Filter, and use the pipe sealant or Teflon tape (PTFE) appropriately. The end threads are not processed to avoid getting the sealant or Teflon tape into the piping system. Y Strainer can be mounted either horizontally or vertically downward.
Warning: When installing 1-1 / 4 " (DN32) or larger caliber insert weld filters or all D series filters, note that the gaskets for such filters are non-metallic and prone to damage due to overheating. The welding time should be shortened and the filter should be cooled after welding. If preheating is required before welding or continued heating needs required after welding (the D series filter), it is recommended to remove the gasket and reheat it first. Operation and maintenance of the Plastic Strainer: after the initial operation of the system (generally not more than one week), it should be cleaned to remove the impurities accumulated on the filter screen during the initial operation of the system. Thereafter, it must be cleaned regularly. The number of cleaning times varies according to the working conditions. If the filter is not plugged, remove the filter limits and filters when cleaning the PVC Strainer.
Note: The filter shall be separated from the pressure system before each maintenance and cleaning. After cleaning, use a new gasket when reinstalling.
