  • Make sure that the fluids are compatible with the filter material.
  • Follow the flow direction according to the arrow printed on the filter.
  • Make certain that the input/output piping is aligned and that there are no obstacles or restrictions inside.
  • Install the filter on a hard surface and avoid soft materials such as plastered walls.
  • Install the filter with the cleaning handle (flywheel) turned upwards.
  • We recommend installing a bleeding valve in the closed circuit to avoid overpressure due to the fuel temperature variations.



 To clean the filter, simply twist the handle at the top of the unit – this process can be manual or automatic (motorised using a variable speed drive).
