I have a Eco Kleer 200sq filter system by waterway. The unit shows to use a 817-0200N filter which has a 4" inside diameter, but my unit has a another part inside of the system as shown in the attached picture which has a 6" diameter. What is this addition part that the filter slides onto. And why would the system state to use a filter with a 4" diameter filter but have this part which requires a 6" diameter filter
